Top 5 Courses to Learn MySQL in 2020

Introduction It’s no real secret that the United States has an interesting relationship with banking. In the wake of the Great Depression, many Americans felt skeptical about banks and their ability to safely store their life savings. Even to this day, certain older Americans carry this skepticism with them. The financial crisis of 2008 renewed these suspicions, as major American banks were certainly not blameless in the collapse. While some Americans may have been tempted to terminate their accounts, there was really no viable alternative. Whether we like it or not, we all have to entrust our savings to financial institutions. If people have learned a lesson from the 2008 crisis, it’s that they need to educate themselves with regards to how banking actually works, and what steps major banks are taking to ensure the security and stability of customer accounts. This practice is especially relevant to those of us working within tech. For one, we tend to have more to protect, and second, banks are relying on tech tools and systems to prevent potential mishaps. With the help of an expert insider, we’ll be able to gain a more in-depth understanding of how banks can protect their customers and the role regulation plays in guaranteeing account safety. The Enforcer Federal regulations exist to make sure that banks, especially large banks, are doing all they can to prevent problems. In addition to these regulations, there are a number of internal efforts that have the same goal. To put it plainly, there are many different regulations and considerations to keep track of. This poses a challenge, as many banks are enormous entities, and as we all know from the recent history of Silicon Valley giants, big companies with a broad sphere of influence can be slow to adjust and adapt to the changing needs of the market and its customers. Aditya Lal has worked in finance for many years, and he currently holds a number of prominent certifications, including both PfMP (Portfolio Management) and PgMP (Program Management) certifications. He also serves as a CCAR (Comprehensive Capital Analysis Review) professional, a crucial step in preventing financial crises that we’ll be discussing in detail later in this piece. At the moment, much of his work surrounds FDIC 370, a measure that Lal helped us to understand in greater detail. We also used this opportunity to ask Lal about a few other topics in banking including how federal fines can affect individual customers and how well-equipped banking executives are to deal with much-needed adjustments and improvements. FDIC 370 and Why We Should Care Let’s start off by discussing a specific regulation: FDIC 370. The ultimate goal of this measure is to make sure that each account owner can be protected in the case of a banking institution’s failure. The nuts and bolts of this measure focus on accurate recordkeeping and reporting, which, in effect, requires banks to make sure that their system is capable of keeping accurate, up-to-date records for every single account holder. As Lal pointed out, the regulation also ensures the health of the economy as a whole, since economic stability depends so heavily on the extent to which banks can be trusted and relied upon. “The basic objective of this regulation is to determine insurance deposits in a timely and accurate manner in case of the bank’s failure. However, in doing so, it will also bring economic and financial stability by disbursing the correct amount to a depositor as soon as possible. In fact, the FDIC wants to receive all aggregated and calculated data from the bank within 24 hours of its failure.” If the measure sounds strict and demanding, that’s because it is, and with good reason. If followed to a T, then this kind of accurate reporting and dependable insurance could prevent a large-scale financial crisis. Executive Involvement in Regulation So have banking executives been up to the task thus far? Members of the public have reason to feel a bit tentative about the wisdom and expertise of banking executives, given the stark reality of recent American history. Thankfully, Lal explained how executives are often heavily involved when new regulations are being devised. This kind of roundtable discussion gives those at the top the opportunity to express potential challenges they may face, thus assessing the practicality and timeline of each regulation. We’ll let Lal elaborate on how executives can contribute positively to the discussion. “These executive are supposed to bring in real-time challenges that a bank may face while implementing new regulations. It also gives them an opportunity to learn and understand the new regulation so that they can keep their regulatory department up to date and provide enough information about the upcoming regulators to their mid-level managers.” This kind of understanding has to start the highest level. Should executives not have a full understanding of changes that need to be made, then it’s much more likely that these changes will suffer from miscommunications. Executives need to be on the ball at all times, and according to Lal’s extensive experience with banks and banking executives, they are more than capable of rising to the challenge. “To my knowledge, executives, management and mid-level managers are adequately knowledgeable in the regulations of their area.” The Ripple Effect of Bank Fines “Customers get hit directly when banks receive fines. It is imperative to mention that these practices and fines bring further instability to the financial sector and the economy in general. The 2008 crisis was all about malpractice within banks, leading to one of the greatest recessions in recent history. To curtail these illegal practices, regulators have to create even more regulations, which require millions of taxpayer dollars to implement.” Why CCAR Remains Crucial Stress testing is a concept that gets discussed quite often during media coverage of banking scandals and new forms of regulation, but it is rarely explained in detail. Let’s take a brief look at the true purpose of financial stress testing, referred to as CCAR, and why it’s an absolute necessity in the financial sector. “Stress tests are ‘what-if’ scenarios defined by the Federal Reserve Board as Baseline, Adverse, and Severely Adverse scenarios.” In essence, it’s the practice of a financial fire drill, accounting for fires of different sizes and intensities. What would happen if the economy encountered another major recession? What if the American economic system collapsed entirely? CCAR testing guarantees that individual banks would be capable of handling quite severe situations. “It ensures that banks have the ability to absorb losses, even in severely adverse scenarios. Also, it ensures that large and complex banks should have enough funds and can provide access to those funds, even in adverse and severely adverse scenarios.” It should be clear now why stress testing is one of the most important steps that can be taken to prepare for potential financial disruption in the future. Without it, we would run the risk of suffering yet another crippling financial crisis. Making Emerging Technologies Accessible In closing, let’s discuss Lal’s view of emerging technologies and how they can offer immense benefits to industries of all stripes, from finance to emergency response, and everything in between. Lal previously worked with GE in the early 2000s, and during this time he saw a major opportunity, one that would require a serious overhaul of existing practices. Specifically, Lal worked within GE roadside assistance. In 2006, he recognized a consistent problem. Namely, if someone was traveling and wasn’t familiar with the immediate area, then that person would not be able to identify their location to roadside service representatives. This poses a clear conflict, as precise location is an absolute necessity when providing roadside service. “In the early 2000s, we partnered with a number of cellular service providers. It is important to recall that GPS was a privileged service at that time and not many customers wanted to pay for GPS services. After a lot of discussions and IT, we were able to use the caller’s coordinates to find the correct zip code and determine the nearest provider using analytics.” This represented a huge step forward in an industry where time is a major factor, especially in emergency situations. So how does this relate back to current initiatives within banking? It serves as a powerful reminder that tech, especially emerging technologies, can offer solutions to many pre-existing problems, even problems that may not seem dire or in need of an immediate fix. In particular, Lal and other financial professionals like him are using updated IT systems to protect consumers. Without these tech tools, adhering to recent federal regulations a daunting challenge, to say the least, and many banks would be at risk of failure, unable to guarantee their many accounts. Even if you don’t work within finance, we implore you to look for ways in which tech can ensure the safety and satisfaction of the public in your own industry, whatever it happens to be. Tech is the way forward in all sectors, not just in banking. It doesn’t necessarily decide what our goals should be, but it does determine how, and when, those goals are achieved. <a href="https://medium.com/media/3c851dac986ab6dbb2d1aaa91205a8eb/href">https://medium.com/media/3c851dac986ab6dbb2d1aaa91205a8eb/href</a>

Aditya Lal Keeps Banks on Their Toes, Poised to Protect Customers

Banks are researching blockchain technology to reduce costs. The modern banking system dates back to the 13th century in Italy where the most famous bank across Europe was the Medici Bank. Their main innovation was the combination of banking and accounting systems, writing double entry data inside a general ledger. A bankers job was to track debits and credits or handle deposits and withdrawals for clients. They had to make sure entries were placed in a safe place and funds were secured. Trust and talent were one of the biggest components for a banks success back then and for decades to follow. For centuries, some of the biggest companies and salaries around the world came from the banking industry. However, during the 2008 financial crisis, this trust between banks and clients took a hit. Many banks had mismanaged their clients' funds and it was time for something new. Many startups jumped into the scene and offered mobile-first banking solutions, UI/UX friendly etc but the problem was still there. Human error, corruption, pen and paper records, and mismanagement of transactions would not go away with the current system. It was during this time that a new technology was being introduced to the world. This technology allowed third parties to track transactions in a public ledger, transfer value around the world at a faster pace, and manage pseudonymous identities online all without the need of a central entity. This technology was called bitcoin, introduced by Satoshi Nakamoto. Bitcoin unknowingly introduced a triple-way accounting system that banks could leverage to evolve their current infrastructure. Banks research blockchain technology Now, bitcoin might have been created to decentralized the current banking system, but this won't stop banks to research and try to leverage this infrastructure and evolve their systems. Managing a personal bank account might not be for everyone even though bitcoin facilitates the tools of doing so, even for the 2.2 global Billion global unbanked population. Blockchain reduces the infrastructural cost of running a bank. This may help banks (or other startups) to onboard this large unbanked population. : According to Mike Bodson, CEO of DTCC (check out his interview for The Blocks podcast) “U.S. markets let’s say it’s about 65 billion dollars for equity markets. Their belief is that within five to seven years, I think, that’s 65 is going to go down to 48 billion dollars. So you’ve got this massive pressure on costs. Right. And all the Wall Street firms have done the same things over the last few years, you know. They’ve all tried to modernize but we all sit off old legacy technology. You’ve outsourced, you’ve sent things overseas. You’ve done all sorts of things to try to drive that cost base down but at the same time you’ve got the pressure of compliance and regulation, which is making your costs go back up.”. : DTCC spends $1.4 billion each year, and 50% in tech ($700 Million) and handles $1.8 quadrillion of trades every year. Note Long term opportunity Every bank is focusing on reducing costs, and blockchain technology might just help them achieve part of it. They can transition key operational, risk and finance systems to blockchain platforms. made a report on what areas could benefit blockchain the most. Accenture Some of these areas could see a 70% disruption impact due to their easily automative nature. Imagine having all trades within one database where anyone can audit its history, and current trades are updated live. Since all trades are digitized, there are no more worries that if a storm comes it could damage the place they are stored and lose valuable time to re-inform the network. Also, since a blockchain stores trades in a distributed network, no one can hack it, tamper it, or corrupt past information (unless they own 51% of the computing power which is another story). Accenture finalized the report saying blockchain can help save ~$8 Billion if systems are upgraded. Current blockchain solutions for central banks Since 2014, central banks have been investigating the applicability of digital ledger technology for various banking obligations, with some 40 central banks doing so today. While blockchain, like any new technology, is full of unknowns, experiment and research points to significant advantages from central bank adoption of CBDCs (Commercial Banking Digital Currencies) and DLT (Distributed Ledger Technology). In this white paper, ten use cases are put forward: World Economic Forum Retail CBDC for consumer use similar to physical cash or alternative bank deposits. Wholesale CBDCs for interbank settlement on the commercial level. Interbank securities settlement to allow simultaneous, peer-to-peer asset trades. A primary or back-up domestic payment system in case of emergencies. Sovereign bonds issued and managed by states who act as nodes. Financial tracking of AML/KYC information as a unified information outlet. An information sharing site between public and private entities for financial data flows. Trade finance issued on a distributed ledger to increase domestic and global efficiency. Cash flow supply train to track and analyze large cash flows between commercial and central banks. Blockchain database for the EU’s SEPA credit system to increase overall efficiency between member nations. Retail CBDC for consumer use similar to physical cash. In a future where consumers use less cash, it is vital for a country to introduce a good CBDC. Especially in countries where commercial banks are unstable and deposit insurance is not offered. CBDC can be the answer for financial inclusion, especially with a 52% mobile penetration rate.( ). Statista Wholesale CBDCs for interbank settlement on the commercial level. Central banks coming from emerging countries can beneficiate the most to settle an instant transaction. Central banks with already efficient systems (such as the Bank of Denmark) can create a primary or back-up domestic payment system in case of emergencies. The intersection of emerging countries and developed banks can create the necessity of everyone being on the same page. So if say the Bank of Denmark is using blockchain as a backup, and the Bank of Argentina as primary, it might be necessary for them to use the same technology to settle transactions. Blockchain-based issued bonds issued. French banking group has issued a 100 million euro covered bond on the Ethereum ($ETH) blockchain as a security token dubbed “obligations de financement de l’habitat” or OFH. The bond is rated Aaa/AAA by Moody’s and Fitch and was part of an internal startup program for fintech experiments. Societe Generale Blockchain allows Societe Generale to explore a more efficient process for bond issuances in real time. The blockchain bond reduces time to market, increases transparency, and faster transportability, and settlement. A smart contract automated the whole process. Afghanistan, Tunisia, and Uzbekistan have been testing sovereign blockchain bonds to help out critical sectors of the economy and increase trust in their markets. Afghanistan is interested in issuing a bond tied to metals. specifically the country’s $3 trillion lithium industry. Uzbekistan was interested in issuing blockchain bonds for its cotton industry. Tunisia would issue a bitcoin-based sovereign bond. ( ). Asia Times Financial tracking of AML/KYC information as a unified information outlet. According to Banque Centrale de Tunisie governor Marouane El Abassi, Blockchain based bonds can combat money-laundering, manage remittances, fight cross-border terrorism and limit grey economies. ( ). Asia Times Banks already testing or using blockchain technology BNY Mellon- Blockchain based US Treasury bond settlement The Bank of New York Mellon, is an American worldwide banking and financial services holding company headquartered in New York City with $1.8 Trillion in assets under management. They focus on providing a suite of foreign exchange, securities finance, collateral management and segregation, capital markets and prime brokerage services as well as custody and wealth management. They launched the US treasury bond settlement- with blockchain technology back in 2016 as a backup record to their system. This blockchain can reduce the three-five days settlement of bonds to 1–10 minutes in a secure, transparent, more affordable, and instant manner. The backend is bypassing intermediaries that do not trust each other and antiquated infrastructure by clearing and verifying a bonds authenticity within a blockchain. BDS360 Banco Santander- Cross-border transactions Banco Santander is a Spanish multinational commercial bank and financial services company founded and based in Santander, Spain raking $54 Billion in revenue in 2017. With services all around the world, Banco Santander and blockchain technology are a match made in heaven due to the instant cross-border transaction this technology offers. Together with Ripple’s service Xcurrent, Santander launched in 2018 to roll out a distributed app (Dapp) offering same day International transactions for customers in Brazil, Spain, U.K, and Poland. The traditional system takes three-five day and charges an average of $25 fee + 3–7% to its customers depending on the bank to finalize an international transaction. One pay FX ING- Zero knowledge proof set membership The ING Group is a Dutch multinational banking and financial services corporation headquartered in Amsterdam. Its primary businesses are retail banking, direct banking, commercial banking, investment banking, asset management, and insurance service with 37 million clients worldwide. They have tested blockchain technology to increase in a public ledger using Zero-Knowledge Range Proof (ZKRP) solutions. Developed in-house, the team’s test has demonstrated significant efficiency improvement to protect clientele private information. ‘Zero-Knowledge Proof’ allows a party to verify the accuracy of a statement without conveying the actual information in the statement. Zcash is one of the biggest cryptocurrencies that uses the ZKRP modeling. confidentiality Approaches Permissionless blockchain A public blockchain (Permissionless blockchain) allows anyone to interact with the network and run a node. Blockchain networks such as Bitcoin, Ethereum, Litecoin, and EOS are permissionless. The benefits of a permissionless blockchain is the basic components of more decentralization, transparency, and immutability. A bank might not be so interested in allowing everyone to partake in the network. Permissionless blockchain such as Monero, Zcash, and Grin are focusing their technology on more private components using Zero Knowledge Proof algorithms. The provides privacy components built on top of the Ethereum blockchain. Aztec protocol Permissioned blockchain Private blockchain (permissioned blockchain) only allows parties with access to the blockchain to participate in the network, check transactions, and audit the information flow. Consortiums are being created to bring all banks together and work on private blockchains without revealing critical data that shouldn’t be seen in public. Ripple, Stellar, Quorum, and R3 are some of the biggest private blockchains or set of consortiums. Conclusion There are many use cases for banks to look into blockchain technology aside from opening cryptocurrency trading desks. Blockchain is beyond the testing phase for the banking world now. They want to know how blockchain will work for them. <a href="https://medium.com/media/3c851dac986ab6dbb2d1aaa91205a8eb/href">https://medium.com/media/3c851dac986ab6dbb2d1aaa91205a8eb/href</a>

When a visitor types your URL or clicks your website on your search result that goes to your URL in a browser, it is presented in HTML. The browser reads the coding and displays that as a user-friendly website page. But more than HTML, content that is available on a website may be hosted on a CMS platform like WordPress has some content within it. This content needs to be stored in a place that is accessible to your visitors. Website content includes: HTML Code Text Image Video CSS files JavaScript files and a lot more. These kinds of files need to get stored on servers so it will be easy for the browser to get your website’s content when they need it. Generally, servers physically located data centers have a lot of hardware and computers to perform an action. And this type of storing your content in a server is called web hosting. To know more about the best web hosting service, visit https://www.bestadvisor.com/picks/web-hosting A lot of web hosting is out there based on your needs and the features that you want to use. Let’s go through them one by one. Free Web Hosting From the name, you got the kind of this hosting service. Yes, you don’t have to pay for this service. You can host your website for free completely. If you are starting out, then you can learn a lot by this free hosting websites. And a lot of platforms are available to host your content for free. They are: WordPress Wix Blogger Zoho Weebly But the thing is you can’t get the complete feature like the self-hosted domain, complete security (important for e-commerce websites), and a lot more features. The above platforms also offer paid services which you have to pay to store your resources on their servers. Shared Web Hosting Shared web hosting is the prior option for those who started or running a small business. Because of their pan and billing features. Shared web hosting is nothing but sharing your server resources with other web administrators. It has both pros and cons. The advantage of this hosting service is that it is useful for a website owner who starts their business on a small scale. It comes with an affordable plan and unlimited bandwidth features. The drawback is that your server space is shared with a lot of other website owners like you. Though the server provider gives unlimited bandwidth, it was shared by hundreds of other site owners too. Sometimes it will slow your website to load and cause some problems. So, you always need to monitor your website’s uptime to avoid the site going down. Reseller Web Hosting Reseller hosting is a kind of web hosting service that allows selling different planned services. The person can have control over the billing for the usage of storage, CPU, and RAM and also can have access to the control panel. This allows the person to offer different schemes of services to their clients which meets their requirements. A lot of web designers are using this reseller hosting service to host the client’s resources in their server space and also can gain some monthly income by this. Reseller hosting provides a lot of features like private name servers, technical support from the host to the client itself, and a lot more features. VPS Web Hosting VPS is generally called as Virtual Private Server and it is functioning as shared hosting. A lot of shared websites are hosted in a single server with few limitations. Normally 10 to 15 websites are hosted in a single server and the server space is divided into small slices. Each slice is acting as a separate server. Dedicated Web Hosting On this kind of web hosting a server is completely is dedicated to your own resources, no other websites or resources are stored on your dedicated servers. A website who handles a lot of traffic is using this kind of hosting service. Other hosting types will not provide this kind of feature, because the server is completely dedicated to you. Generally, you need to know how to manage a server if you want to host in a dedicated server plan. Or else you should need a server administrator to manage your dedicated server A lot of hosting providers are offering managed and unmanaged dedicated hosting services at your convenience. Colocation Web Hosting This is the advanced web hosting services and it is kind of like dedicated web hosting. Colocation web hosting means the content owners have to rent a “space” from data centers. Technically, you have to provide the server hardware, the host will provide the supply, uplink, and facility. You are responsible for the server software, hardware drive, and the backup facilities and also you are responsible for the hardware failure. You have to change the hardware by yourself when it fails. Managed WordPress Hosting Managed WordPress hosting is suitable for those who are not ok with technical things that will face while hosting their website. This kind of hosting is especially for WordPress because the host handles all the things including updating frameworks and plugins. Instead of using CPanel or Plesk, you can handle your back-end details on your WordPress dashboard. Technical support is always excellent from WordPress. It is well suited for the website owners who don’t want to dwell into technical issues caused by the hosting side. Cluster Web Hosting This is also a kind of dedicated web hosting but in a different way. People always used to confuse with the cluster hosting with the cloud or grid hosting. Cluster hosting is a group of servers connected to form a cluster (the group of servers) and interconnected a one to operate as a single “big” server. This offers the web administrators to maintain a huge server at affordable bills. Self-Service Web Hosting Self-service hosting is means by the name itself, you have to rent a place for your server and storage. This is the most advanced web hosting. The complete web hosting is at your own responsibility. The hardware, software, power, bandwidth, cooling, backups, administration, etc. are having to be maintained by your own self. Cloud Hosting Cloud hosting technology was introduced to the world in 1992 and Amazon takes it into the market in 2002. Cloud Hosting is also called as Grid Hosting services. Some famous cloud service providers include Amazon’s AWS, Microsoft’s Azure, Google’s Cloud, etc. Did you use Dropbox, Google Docs, One Drive before? They are the popular applications of cloud service. Cloud hosting is nothing but several servers from different locations or the same location connected together to perform as a single server. It was used to handle the huge spike of traffics and you don’t always have to pay unnecessarily in cloud services. You only have to pay for the resources you have to use. Conclusion Here we listed the different kinds of hosting and it is up to you to choose the best hosting service that will meet your requirements. People generally go with shared hosting, because it is the basic hosting service with a lot of features. They upgrade or downgrade their plans and hosting based on their requirements.

AI Catflap to Stop Adorably Named Cat, Metric, from Killing Birds, Built by Amazon Engineer In order to stop Metric from following his instincts, Hamm hooked up the cat flap in his door to an AI-enabled camera (Amazon’s own ) and an Arduino-powered locking system. DeepLens The camera was loaded with machine vision algorithms trained by Hamm himself. They identified whether Metric was coming or going and whether he had prey in his mouth. If the answer was “yes,” the cat flap would lock for 15 minutes and Hamm would get a text. (In a nice flourish, the system also sends a donation, or “blood money” as Hamm calls it, to the National Audubon Society, which protects the birds cats love to kill.) — the verge

“Banking is necessary, banks are not,” said Bill Gates in 1994. In 2009, Bitcoin came along. Blockchain technology has opened up new possibilities to build better financial products that operate without the need for central authorities or banks. I started Constant to build financial products based on P2P technologies. Our products belong to our users — they collectively operate, secure and enrich everything we build. Everything is open-source. Anyone can take part. What follows describes our first product: decentralized, fully-secured P2P lending. Access to capital is key — to start or grow businesses, fund personal goals, support relationships, and pursue a higher quality of life. The more affordable capital we can provide, the more helpful we can be. The evolution of lending You are a lender whether you like it or not. happens once you deposit money into a bank. Your bank immediately loans it out to others via products like credit cards, charging predatory interest rates of up to 30% APR. The bank keeps most of these profits. You earn the national average of 0.8%. Subject to yearly inflation of around 2%, we’re effectively paying banks to store our money. Traditional lending in the UK in 2005, and have since emerged as a popular alternative to traditional lending. However, they come with their own set of problems. Most offer risky, unsecured loans that have resulted in substantial losses for investors. P2P lending platforms began with Zopa In China, for example, the once booming P2P lending industry has since . Many platforms have either gone bankrupt or been unable to repay investors. In extreme cases, employees have simply run off with investor funds. Regulation has struggled to contain the problem, leaving many people out of pocket. fallen victim to scammers and rising defaults With the introduction of blockchain technologies, we now see a number of — Dharma, Compound, and Constant — working on building better P2P lending platforms. crypto P2P lending platforms While our approaches differ, we all aim at building fully secured peer-to-peer lending platforms that replace reluctant trust with cryptographic proof, allowing any two anonymous parties from anywhere in the world to lend and borrow directly to and from each other, without the need for a trusted third party. Loan management, collateralization and repayments are carried out collectively by the users of the network, protecting them from any single point of failure. This unique P2P property bypasses the need for a central party and allows for new, exciting use cases. The traditional loan agreement has been replaced by an unstoppable Ethereum smart contract. It runs exactly as programmed — to return collateral to the borrower after repayment — without any possibility of downtime, fraud, or third-party interference. Once investors and borrowers commit to a loan, it is irreversible. Repayment is guaranteed. All this happens . If these platforms disappear, the smart contracts will continue to perform their function, collectively powered by all the nodes of the Ethereum blockchain. without a central authority or a bank Fully-secured, blockchain-enabled P2P lending is our contribution to a bankless banking system. Of the three competing business models, which is the superior? Shortcomings of current crypto P2P lending platforms While there are a few crypto P2P lending platforms today, their products are designed for a small, niche audience: crypto savvy traders. Constant is built more broadly for the everyday user. We aim to reduce friction and ease transition into decentralized finance, by first building bridges between the existing financial system and its new alternatives. As of May 15 2019, the combined loan volume of the two largest platforms, Dharma and Compound, is just shy of a modest $10 million. . The right product will migrate users and trigger mass adoption. Global debt has just reached $215 trillion Let’s take a look at the shortcomings of current blockchain-based P2P lending solutions that stand in the way of mass adoption. Lack of fiat support Current solutions are exclusively crypto-to-crypto, as one might expect from P2P lending platforms built on blockchain technology. However, most of the current volume is generated by the crypto-trader community who long or short cryptocurrencies. Very rarely do these solutions impact other demographics. Constant operates using USD stablecoins — cryptocurrency that is 1:1 pegged to USD. The platform hosts conversion of USD to stablecoins, as well as stablecoins to USD. As such, Constant makes crypto lending with USD stablecoins logistically identical to investing and borrowing USD. Loans can be easily put towards real-world use cases, such as buying a car, consolidating debt, or paying for a vacation. Investments appreciate steadily, without the typical volatility characteristic of the wider cryptocurrency market. Lack of collateral choice Current solutions offer a limited number of crypto assets as collateral (mostly BTC and ETH). We believe that more and more real-world assets will be tokenized. The more assets we support, the easier it will be for our users to get liquidity from their assets. Constant’s engineers are working hard to add as many collateral types as possible. In addition to BTC and ETH, we are onboarding many additional ERC tokens. We’re also working with other blockchains to bring their tokens onto Constant, such as EOS, TRON, and TOMO. Centralized interest rates Other solutions are decentralized to varying degrees, but interest rates are set by the company, just like banks do. In our view, interest rates are a critical component and must also be decentralized. Constant peer-to-peer lending offers an order book solution. On Constant, the users, not the platform, set their own investment and loan rates. It’s 100% market driven. High margins Current solutions set fixed rates and earn the difference. For example, if the interest rate for investors is set at 4%, and 10% for borrowers, the platform absorbs the 6%. This is also how banks work. Banks set their own rates and earn the difference. Constant doesn’t work this way. Constant simply matches investors and borrowers at the rate they agree on, and charges a minimal service fee. Lack of cross-border use cases Current solutions are somewhat insular, located mostly in the US. Constant’s team is located in both the US and Asia. We believe that bridging developed economies and emerging markets is the way forward, essential to building a global P2P lending network. Developed economies have plenty of low-cost capital but enjoy almost no returns on their savings. People in emerging markets suffer from high interest rates and lack the means to obtain traditional requirements for borrowers, such as credit scores and background checks. Introducing Constant: a Crypto P2P Lending Platform The Order Book In a , the tradable asset is a , and traders trade on (e.g. sell 100 shares of Apple at $200 each). stock exchange share share unit prices In a , the tradable asset is a , and traders trade on (e.g. buy 2 Bitcoin at $7,000 each). coin exchange coin coin unit prices Similarly, in a , the tradable asset is , and traders trade on . fully secured peer-to-peer lending platform cryptocurrency the interest rates of that cryptocurrency A P2P lending market trades on interest rates Running on top of the Ethereum blockchain, Constant is a peer-to-peer lending platform that provides a simple way for anyone to: Place an or . Invest Order Borrow Order Be a (set the interest rate) or a (take the interest rate). Market Maker Market Taker instantly. Borrow money Secure collateral with a . Smart Contract The Constant Pro web interface gives professional traders insight into the Constant P2P lending market The Matching Engine The Constant algorithm matches investors with borrowers glad to pay their rates. It then secures investor funds and borrower collateral in an unstoppable smart contract, and facilitates the entire transaction from beginning to end. Unlike P2P lending platforms like LendingClub, all loans on Constant are fully secured. Constant’s lending mechanism is designed to bring people together to do business on their own terms Automatic Liquidation If the collateral value falls to 110% of the principal plus interest to date, Constant automatically sells it to pay back investors, and refunds the borrower the difference. In this scenario, investors get the principal back, plus their profit to date. They are able to then re-invest and find a new match. Early repayment Borrowers have the option to repay early before their collateral value hits the threshold for automatic liquidation. If less than 75% of the term has elapsed, they pay full interest for the time before repayment, and 50% of the interest due for the rest of the term. If more than 75% of the term has elapsed, they pay 100%. In this case, investors also get their principal back, plus their profit to date. They then have the option to re-invest and find a new match. Here’s an example: Jon invests $10,000 at 12% APR for 6 months. Annie accepts his terms for her loan. Three months later, Annie decides she wants to repay early. Annie repays the loan of $10,000, and the interest due — 12% APR for 3 months, and 6% APR for 3 months — bringing the total amount due to $10,450. Jon has earned 12% APR for 3 months, and now has the option to withdraw $10,300, or re-invest and find a new borrower. Noncustodial Collateral is stored in a smart contract. All parties — the investor, borrower, or Constant — cannot move the collateral at any time, unless it meets the programmed conditions such as a repayment or default event. Coins Constant supports stablecoins, as well as fiat currencies which are converted automatically into stablecoins in the backend. Constant will add more stablecoins over time, but only those with liquidity. At the time of writing, Constant supports the following stablecoins: On the investment side, USDC TUSD PAX GUSD USDS Invest in fiat or stablecoins — the choice is yours , Constant supports multiple collateral types. Constant will add more coins over time, but only those with significant liquidity to ensure the smooth running of the platform. At this time, Constant accepts the following coins as collateral: On the borrowing side BTC ETH BNB BAT REP OMG HOT ZRX VET TOMO ENJ ZIL DGD DGX KCS FTM IOTX LRC NULS Constant supports diverse coin portfolios Multiple devices Constant provides cross-platform web interfaces for: Desktop Mobile iOS Android Seamlessly switch between all your devices Multiple languages The initial release will be in English and Vietnamese. More languages will be added over time, including Spanish, Chinese, Korean, and Japanese. API Constant will provide an open REST API for other platforms to integrate with ours. Here are some potential use cases: Integrate with wallets, creating “Instant Borrow” and “Instant Invest” buttons Integrate with PoS (Proof-of-Stake) chains to earn interest on staked collateral Integrate with exchange reserves Oracles Oracles play an important role in the design of Constant. They feed diverse external data (such as the current BTC price) into Constant, removing single points of failure. They enable real-time percentage updates of the value of collateral used to secure the loan, and allow for liquidation to kick in accurately. Multiple oracles ensure we have accurate data Oracle Network The Constant oracle network consists of a number of circles. Each circle contains a number of oracles. Oracles within a circle work together to report on a piece of data (i.e. the current price of Bitcoin or Ethereum). An oracle can join and leave a circle as it wishes. Oracle circles Each circle contains the following fields: The sources of data The (i.e. number of oracles) size of the circle The : mean, median, or mode reduction method Oracles combine to provide important data to the Constant platform Reduction Method: Median An oracle has the following fields: Oi is the value provided by Oi Vi is the timestamp of the last update from oracle Oi Ti is the number of times Oi submits wrong values Wi is the quorum (initially, 10 oracles) Q is the valid timestamp range (initially, 10 seconds) T is the maximum number of times an oracle could be wrong (initially, 2) W is the acceptable error margin, |Vi — Vj| < e then Vi = Vj e The is the median of the set S = { V1, V2, …, VN }, where value V |S| > Q now() — Ti < T Wi < W Let Scorrect be the set of values between the 25th and 75th percentile. An oracle Oi whose value is not in Scorrect is considered a wrongly submitted value (hence their wrong score Wi), and will have 1 added to it. Add/Remove Oracle Initially new oracles are added by the Constant core team. While this is somewhat centralized, it’s critical to keep the data feed accurate. Current solutions are simple and straightforward, designed to avoid Sybil attacks. In the future, we may replace this with a more decentralized solution. An oracle Oi is immediately removed from the network if Wi > W, or if it is voted out by the board. Incentive / Payout The incentives are structured around base payouts and commissions: is base payout per update, set by the Constant team B is commission payout per update, set by the Constant team C is total payout Oi, paid per update Pi The payout for Oi ∈ Scorrect is: Pi = B + C * | Δ — 2 * (Vi — V) | / Δ Δ = | V25% — V75% | Fees Matching fees Constant charges service fees for matching borrowers with investors. The current fees are 1% for borrowers, and 0% for investors. Deposit & Withdrawal fees Most deposits and withdrawals are free. We charge minimum fees for fiat deposits and withdrawals, to cover operational costs incurred by working with the banking industry. Bank wire transfers continue to be the most expensive method of transferring money Risks & outstanding issues There are many risks involved in operating a decentralized finance product. User fund security Many financial products have failed due to poor security implementation, resulting in lost user funds. Our team mitigates the security risks in these ways: Fiat currencies are held in FDIC-insured trust accounts insured up to $130M. The collateral is held in Ethereum smart contracts that securely lock the assets. Users have the option to store their collateral with our independent crypto custodian partner that offers up to $100M in insurance. Dissolvement of Constant Many financial platforms have failed and caused losses for their users. Constant protects users In the unlikely event that the team is dissolved; the technology it is built on ensures users’ funds remain protected and the loan contract runs as programmed. No smart contract support for BTC While most Constant loans are backed by smart contracts, BTC-collateralized loans are not, simply because Bitcoin doesn’t have a smart contract language. Our team mitigates the security risks in the following ways: Use an independent party to manage the BTC collateral such as BitGo or PrimeTrust. Implement a 2-out-of-3 multisig BTC address to manage the collateral (under active research and prototyping). Constant is designed to protect both investors and borrowers. For investors, if borrowers default, collateral is sold to refund the investor. If collateral falls in value, it is sold at a threshold. It’s all automated by an unstoppable smart contract — investors will always get their principal and their profit. For borrowers, borrower collateral is stored safely in a smart contract escrow, powered by the Ethereum network. This runs exactly as programmed, independent from human intervention — no one can touch these assets. As long as borrowers repay, they will always get their collateral back. We hope that Constant will be helpful to a lot of people. <a href="https://medium.com/media/3c851dac986ab6dbb2d1aaa91205a8eb/href">https://medium.com/media/3c851dac986ab6dbb2d1aaa91205a8eb/href</a>

Lessons from becoming a Machine Learning Engineer in 12 months, without a CS/Math degree

It’s out with the old, in with the new, just like Marty McFly and his hoverboard. The world is changing, and changing fast. The quantum computer, the new hoverboard or Segway, eliminating the skateboard, the classical computer, and a new law is telling us all about it ‘If you can fathom quantum mechanics without getting dizzy, you don’t get it.’ ― Niels Bohr Beethoven’s Replacement The advancements the world is undergoing in regard to quantum information systems is unprecedented. Moore’s law, the theory formulated by Gordon Moore, an American engineer, businessman and the co-founder of the Intel Corporation, states the number of transistors in a dense-integrated circuit doubles approximately every two years. That was then but this is now, though. Move over, Beethoven. Late last year, computer scientists working at Google did some calculations on the company’s most advanced quantum processor. Strangely, they managed to achieve the same calculation on a regular laptop. A month or so later, at the beginning of 2019, they carried out the aforesaid test on a better quantum chip. Unsurprisingly, they were forced to carry out the test on a much more advanced and powerful computer in order to get the same results as previously done. Again, a few weeks after that they ran the experiment once more but were unable to simulate the results on any form of computer at hand, even the most powerful one. To complete the testing, drastically, they had to use Google’s server to complete it. Call it desperate measures. Enter Hartmut Neven Technology is moving forward like a tsunami and we better be ready for it. The exponential growth of quantum architectural systems in recent times is a surprise to many. Hartmut Neven. Source: cio.com The man responsible for all this, , has even got a new law named after him for his efforts: , which is basically the surmise how quickly quantum computers are gaining supremacy against their classical brethren. Hartmut Neven, director of the Quantum Artificial Intelligence Laboratory Neven’s law It’s Moore’s law 2.0, a kingsize improvement on technological advancement that will only grow as the quantum chips become better, faster. Watch this space. Neven said: “It looks like nothing is happening, nothing is happening, and then whoops, suddenly you’re in a different world. That’s what we’re experiencing here.” Unlike Moore’s law, whose exponential growth was counted in years, every two years, in fact, Neven’s law is inexplicable in the speed of its growth. Improvements in performance are ’, meaning they increase by powers of two. Upgrades in quantum processing power can seem slight at first, not imperceptible in performance, but later ones are clearly noticeable in computational speed, resulting in enhanced quantum execution. ‘doubly exponential The power of quantum computers over classical models comes down to two factors: the first of these is that a qubit has four times more computational power than a normal bit, which is a binary piece of information, based on the binary or base 2 numeral system, as a circuit on a quantum model has, say, four qubits, it would take sixteen ‘normal bits’ to achieve the same computational results on a classical computer, or something to that effect. Secondly, is the speed at which quantum computer processing power is improving at a lightning pace. The chips in the processors are exponentially getting better with time and at a greater rate than processors did in the classical age of computers. This has seen vast upgrades in performance power and the error rate in the quantum computers — a big problem in earlier models of quantum information systems — being reduced. Quantum error reduction, so important in sustaining the qubits superposition and entangled states, is the key technical conundrum in moving the technology forward and taking the architectural systems out of the university and research labs and into the realm of real, utilitarian applications that can improve our lives and help humanity. Viva The Classical Computer! There are quite a few people, however, who believe that classical computer models still have their uses and are not as redundant as those computer scientists and physicists supporting quantum computers say. Advocates believe, in light of the approaching redundancy of Moore’s law, that classical computer chips and more coherent and efficient algorithms are also improving, which will only enhance classical computers lifespan. The road ahead, the target researchers and developers are reaching towards, is ‘quantum supremacy’. This term, this technological position or state of mind, if you will, has so far has eluded us. Source: the statedtruth.com To get there is problematic, but if anyone is going to, then IBM, Google or any of the other companies interested in steaming ahead, should, with the right attitude and people on board, get closer to the goal. It is obvious that as chips become better, quantum computers will become faster and faster, and will, no doubt, be able to solve problems that even the most powerful of supercomputers on the planet won’t have a chance of solving. It is only a matter of the number of qubits available, and the error rate reduction established within the confines of the quantum architectural system against the operational fluidity of the operations. Let us, then, at least for the time being, clap and congratulate Mr Hartmut Neven on his achievements: it is not every day that a town, a street, or even a law as in Neven’s case, gets named after you. Basking in such adulation can go to some people’s heads, but I would put a question mark on the German academic resting on his laurels. I’m sure, this is nothing to him, and discovering practical solutions to the hard problems of quantum computers is more of a motivation for his quest for scientific truth than any base accolade or hubristic accomplishment. <a href="https://medium.com/media/3c851dac986ab6dbb2d1aaa91205a8eb/href">https://medium.com/media/3c851dac986ab6dbb2d1aaa91205a8eb/href</a>

Neven’s Law: Paradigm Shift in Quantum Computers

To be successful is to achieve an intended goal. Where there is no goal, there can be no success. The journey towards becoming a globally competitive software engineer is not always smooth. Aspiring developers often doubt themselves at some point, and experienced engineers might suffer from the . “ Impostor Syndrome ” In this post, I will share some tips on how you can badge the title “excellent engineer” from managers. I will also highlight some day-to-day coding habits to help you achieve this. Before you read further, I want to be able to make you think differently about yourself. Purge yourself of negative mindset like, , . This is not true. You can learn new things, you are better at something, you can improve the skills you already have. Picture yourself living in a global world. No one will see you as a global software engineer if you don’t present yourself as one. It all begins with how you think of yourself. There are some habits you may need to unlearn. excellence is not for me I don’t have natural talents and potentials Like Edmond Mbiaka said, “Take positive care of your mind, and it will surely take positive care of your life.” As a mentor in the I frequently share my thoughts with my mentees. These are my words to them; Microverse program, Successful software engineers: set definite goals, and choose excellent day-to-day habits ”. Yes! You work so hard, and so smart but can you engage the force of excellence to achieve your desired goal (success).? “To be successful is to achieve an intended goal. Where there is no goal, there can be no success Excellence is a lifestyle, not an event. It is an undeniable distinguishing factor in life. Oftentimes you want to get one thing done, move to the next, and the next, and the next. But, remember no employer will recruit a loose developer irrespective their talents. Adopting a culture of excellence in your daily development activities will make you consider: creating clean commit messages writing tests to check your code performance and output, instead of making “ ” code assumptions using pull requests to improve your code managing details when creating models, UI/UX in a manner that is beyond the usual adopting standards tracking how you spend your time asking questions to gain clarity and reduce loop-back consequences taking short breaks as often as you can “I’m not a great programmer; I’m just a good programmer with great habits.” ― Kent Beck Here are six cornerstone habits that will help you achieve excellence and make you a globally competitive software engineer. 1. Be intentional and deliberate You should make a decision about the height you want to meet in your career and be intentional about it. Take your career a little more seriously, don’t just sit idle waiting for someone to ask you to join their team. “ A lack of planning on your part does not constitute an emergency on another’s.” Get to work, get a degree, get training, start somewhere! Excellence is execution tempered with discipline. For me, I believe this is the first place to begin. If you have set some goals for yourself, then its time to move on to the next step. Again, be deliberate about the next few things I will mention below. 2. Evaluate your process(es) Measure twice, cut once. Think twice, code once. “A programmer does not primarily write code; rather, he primarily writes to another programmer about his problem solution. The understanding of this fact is the final step in his maturation as an engineer”. (Anonymous) Ask yourself some important questions. Do you have a process to get things done? How does it help you to achieve the desired excellence? Do you know about ? Gitflow Workflow How meaningful are your git-commit messages? How often do you weigh readability and clean design when naming your variables? Do you create PRs (Pull Requests) so that someone more competent than you can give a code review? How much attention do you give to details? Is code refactoring part of your day-to-day coding habits? Do you create documentation for each feature you implement? How often does your process benchmark performance while writing your code? Asking yourself mattering questions will guide you in building excellent habits. These habits will mould your strengths before hiring managers. 3. Exposure and observation is important Exposure expands your mind, and lack of it can pose a limitation to you. Read about, learn from and associate with people more experienced. Ask smart questions that infer that you crave to grow better. “Questions are the important thing, answers are less important. Learning to ask a good question is the heart of intelligence.” Assumption can sometimes be the lowest level of knowledge. Steer clear of it, ensure that you hold a clear understanding of what to do, and how to do it. Some concepts are difficult to understand, but with practice, they become part of you. You also learn when you visit different cities, attend conferences and meetups. There are more online webinars, Lunch & Learn and training you can attend to expand your mind. I would recommend the program if you are looking to start your journey as a software engineer. Microverse Connect with experienced senior engineers, discover their strategies, observe their style of coding, work ethics, and problem-solving approach. Take advantage of professional social media like LinkedIn. I quite agree with some hiring managers who are of the opinion that “LinkedIn has become a single source of truth for finding professionals." Next… 4. Give your task all it takes, gain the required knowledge Don’t jump steps. If you start a task, stick to it until you finish it. “ ” (Louis Srygley) Without requirements or design, programming is the art of adding bugs to an empty text file. A couple of times you want to reply that tweet, watch YouTube videos, read that medium post, Yes! these are great of course. However, practising with a simple notepad to record ideas that cross your mind will help you maintain focus. Practice time tracking techniques with tools like and . Pomodoro Clockify “Coding requires 1% effort, staying focused on coding requires 99% effort.” Maintaining focus requires deliberate action. Every good problem solver must show great patience in order to get the problem solved. This is a rare quality in software developers. Next... 5. Adopt standards and follow them strictly Most times, when you learn a new language you begin to code in a particular style that you want. However, when you start working on smaller parts of a big application, your style could introduce conflicts and discredit your capacity to work in a team. Software development teams adopt globally accepted standards and will contribute to improving them. Your ability to follow standards will distinguish surely you. Learn about general coding standards, language-specific standards, design principles and stick to them. Standards help you write quality code — easy to maintain and debug. You should: find the best practices for tracking your code performance follow best practices in design patterns for back-end or front-end development follow software development methods practice test-driven development “Programs must be written for people to read, and only incidentally for machines to execute.” — Harold Abelson 6. Understand the law of value “VALUE PEOPLE.” People will naturally value you if you offer them value. Learn to show empathy towards people. Incrementally add value to yourself, improve your communication skills, learn a foreign language, practice public speaking, buy a new pet (if you love pets), visit your family and so on. On the other hand, value your employer, code reviewer, senior engineers, line manager plus other team members. In conclusion, I have highlighted strategies that can help aspiring engineers develop excellent habits Thoughts lead to actions, actions to results, and results lead to good success.

The Six Habits of Highly Effective Software Engineers

What began as a bold idea of ​​creating an alternative to the current monetary system is now beginning to turn into an industry with its main players, basic ideas, rules, jokes, and debates about future development. Followers army gradually grows, mediocre actors and ideas start to take a step back, a community that takes this idea more seriously continues to form. However, two main fronts have been formed — those who try to improve current reality with blockchain solutions; and those who see cryptocurrency victory and formation of a new reality. Among the latter, it is important to single out bitcoin maximalists, who are one of the most influential representatives of this category. So, here is the point. Veterans and soldiers eyes are often distracted from creating tools and solutions for their chosen victory and look at their allies to criticize their approach and ideology. There are some which don’t try to denigrate the other side. There are that are already trying to prove that their approach is more important and significant. And there are those that are to convey a personal vision of the situation. I deliberately chose articles with almost identical titles to show how only one statement “who matters” can be presented in different ways. soft articles more aggressive articles trying to reveal another author’s slyness I am not going to join any of these parties in this article, rather show the senselessness of this dispute. Okay, I’ve stopped these preludes. Let’s start with theses which for some reason many people forget. Bitcoin is not a technology, it’s an economic idea Yes, bitcoin has technological bases like blockchain, a large number of limits, embedded algorithms, cryptographic functions, and other things. Further bitcoin improvement is likely to be technological (second-layer solutions emergence, Schnorr signatures introduction), rather than economical (change in coins amount that can be produced, a strong difficulty change for adjusting the average block generation rate). That’s bitcoin network feature and the conditions in which it exists. But bitcoin itself, as a cryptocurrency, is an economic category. The concept of bitcoin was originally created as an alternative electronic transactions system which doesn’t need centralized moderation. Bases were formed and implemented in accordance with this concept. As a result, we have a system that should resolve the issue of trust to third parties. So, where we have the greatest dependence on middlemen and the requirement to trust them? In the financial markets and when we talk about government. If the government pursues a non-efficient monetary policy which turned “money” into a useless paper, then such government loses users support, and they will start looking for other ways to save their funds. Bitcoin challenges the established system and provides a partial alternative to those who are looking for it — that is why bitcoin is valuable. I don’t want to dive into this, because it’s not a theme of this text and you can find an enormous amount of articles about that. But it was important to say. Blockchain is not a panacea I think everyone read articles where “blockchain can change the X industry because it can make Y more… whatever”. How blockchain will change our life, world, transportation, science, medicine, accounting, content making, automobile industry, etc. This is the first thing I got by googling “how blockchain will…”. Having read such articles, some people sometimes begin to imagine that blockchain is a marvel which is capable to redraw our life. Or they start thinking it’s bullshit that tries to look like magic. In truth, many of the proposed blockchain solutions can be implemented using a centralized system; it can even be more efficient. There are projects that are a kind of blockchain analogue of an existing centralized solution. “Implementing blockchain only for the blockchain” looks like a silly idea. Nothing revolutionary. Sometimes blockchain can become a problem and turn into . Goldberg machine Traffic light on the blockchain I’m not saying that blockchain is a useless technology. Just don’t need to make some aspirin out of it. At least, blockchain showed its viability by being a base to create bitcoin. That’s one type of applications that can be created thanks to the blockchain. And in this case, it’s necessary technology for bitcoin to work and ensure its concept, not implemented to see what will happen. Blockchain is suitable not only to produce endless varieties of cryptocurrency. It can also be used to create other applications but only where it is really necessary. Now let’s take a closer look at the comparisons between blockchain and bitcoin. Car and gearbox Blockchain and bitcoin are two different categories, so it makes no sense to compare between them who is more important. For example, can you tell which invention is more important — a car or a gearbox? Personally, I find it difficult to answer. Bitcoin is not a technology, it’s a combination of technologies that forms a new category — an alternative monetary system. The car is also a combination of technologies that created alternative transport. Blockchain is a gearbox, as it is the technology that helps device (application) work according to a certain principle. If you get the gearbox out of the car, there is no need to say that the car is a useless bucket of bolts and it won’t go anywhere without the gearbox. Gearbox outside the car also has no value. What is the use of having it on your balcony? Thus, they are valuable when working together, not separately. But it doesn’t mean that they cannot exist without each other. You can create a car without a gearbox, like an electric car with only one gear. So, we just change the approach. If gearbox principle is not used in a car, this doesn’t mean that it is no longer a car. It is just another type of car. No one bothers you to create a cryptocurrency without a blockchain. The first thing that comes to mind is a directed acyclic graph (DAG). Some developers try to create “IoT on blockchain”, but blockchain wasn’t designed to be IoT (although I don’t deny if someone succeeds). DAG is already more suitable for creating crypto IoT, but it may need some specific blockchain features. At the same time, gearbox principle is used not only in cars or other vehicles. You can find it in various machines on the plants. I have never worked in a factory, so I cannot fully describe the importance of the gearbox for these machines and its impact on the quality of manufactured goods. I just think that it plays an important role for manufacturers in different industries, because you cannot go far at only one-speed level, and this greatly limits the capabilities of the machine. So blockchain can be used not only for ​​cryptocurrencies. Blockchain activists are trying to shove it in the “machines” of some industries with motto: “Look at these possibilities — it increases the workflow transparency, it’s safer, it can reduce the costs of storing and processing information, you no longer need to have 5 “machines” with different speed, you can use one universal “machine”. Time will tell where this “machines” really come useful, and for what purposes. Bitcoin kids Do you remember the gearbox on the balcony? Оne of the main current arguments of its utility is that it can be used and implemented in other, similar cars. I mean, many of today’s blockchains are very similar to bitcoin blockchain, as it is used as a template. What does bitcoin do well? Decentralized block generation approximately every 10 minutes and conduction of unchanged transactions, ignoring international borders and regulators. And in a sense, that’s all it does. Someone says that it’s not enough to be called a revolutionary technology or idea. This is quite enough for others because almost nothing can provide the same thing. Here we need a hammer and nailing example. Bitcoin will be a standard hammer and hammering nails into the wall — conduction of unchanged transactions. Someone can say that bitcoin is too simple, has “poor” functionality, or irregularly shaped. And what do they do? They produce different hammers for all tastes: someone changes “head” or handle size (hello, Bitcoin… with the second word); someone makes specialized hammers for certain jobs; someone attaches an ax or a nail puller to the hammer on the other side, trying to make it more functional; someone just adds rhinestones, because hammer seems to him a little bit sullen. And everyone says that his hammer is the best and most progressive. What you can see when you on Coinmarketcap Sometimes it’s become ridiculous, especially when nails are hammered with a shovel (hello, Ether) and shovel knights claimed that their tool still can do many other things. Um, guys, no one bothers you to hammer nails with a shovel, but it wasn’t created for that. It can really be useful when you need to build something new, but, please, don’t declare that standard hammer is flawed because of its simplicity. Let every tool do what it was created for. I think everyone will choose what is more convenient and important to him. Some developers just look at bitcoin as a unique principle, not a solution. And I think that it’s some kind of dilemma. Bitcoin is a specific idea and a specific way to achieve it. And some developers just make their “own bitcoin” instead of creating own ideas and own ways. It’s great when you have a choice, but do we really need so many “own bitcoin” solutions? As for me, an approach “take the best from bitcoin” limits the view to cryptocurrency and blockchain technology itself. Although maybe I’m wrong. Why bitcoin is a Model T But if crypto community is more or less determined with the basic concept of how the cryptocurrency should look like, then it can be said that bitcoin is a kind of Ford Model T. Although it can’t be called the first car, it was one which first solved the main problem that prevented the initial mass adoption — price. I came to free horses! The idea of ​​cryptocurrency existed in the 90s. There were such attempts as Bit Gold, B-Money, and Hashcash, but they all had one problem — centralization. Bitcoin solved this problem and received initial support among people who find it important. Has anyone seen a Model T driving around the streets? I think not many of us have seen at least one of these machines live. I know what you thinking but that’s not a statement that bitcoin will be irrelevant with time. Those concepts and principles that we lay in modern cars are the evolution of Model T idea and design. Bitcoin, as we know it, can step aside. Many basics may be modified or replaced, future bitcoin may differ significantly from the current bitcoin. It may lose some modern flaws but it may get new ones, which we don’t think about so far. Even today’s bitcoin is not the same as it was 10 years ago. We don’t know what evolution of bitcoin will be. Maybe the base will remain almost unchanged, and its second- and third-layer networks will already be subject to change and development. Or, it will remain the same ancient Model T which will be collected and used as a store of value. That is why it is not necessary to predict bitcoin oblivion or success. It’s easy to criticize bitcoin and blockchain, and if you are one of these persons who like to write bitcoin obituaries, on how to do it right. I hope it will help you and simplify your work. here is a guide The main thing is that the criticism of bitcoin and its idea should not be reduced to a simple thought: “This brougham has no horse”. Yay! How can we be sure that it will take us in the right direction, and how will we control it? Why invent a complicated and incomprehensible mechanism to move if we can just ride a horse? What makes you think that we will drive this if we ride horses for thousands of years? And what if it breaks? These are all important questions. Perhaps someone will be able to partially respond to them if not just look under the hood, but try to understand how “it” works and what it gives in the end. Yes, the horse is an excellent and convenient centralized solution but it doesn’t mean that we will exploit it forever. A bit about prospects Since the blockchain is a technology, it is easier for it to take over the world. It can be implemented, and then you would understand what results it gives. You can constantly try and recheck until you find the best option, or you can throw it out as unnecessary. No need to create a new reality and change people’s perception drastically, you can simply modify something that already exists. Blockchain seems more real and promising because of this. That’s more complicated with ideas such as bitcoin. If technology is objective, then the idea is intersubjective. Idea’s influence and credibility grow with the number of supporters who see a sense in it. Money, nation, religion, human rights — these are all intersubjective ideas and myths, and systems that were built around them are much more powerful than any technology. The idea can be realized by various technologies, we just choose the approach. It reminds Nassim Taleb’s phrase: Ideas are always stronger than technologies but not always more promising. “Bitcoin will go through hick-ups (hiccups). It may fail; but then it will be easily reinvented as we now know how it works”. Yes, bitcoin can become a kind of insurance policy for now but I don’t think that someone would like to get into a situation where a person will be bitcoin, as in Venezuela. It’s much better when a person it. And you need to strive for this, dear bitcoin anarchists. forced to use wants to use Although the blockchain and bitcoin have one starting point, they have different paths of development. Please, don’t argue with allies who are better and more important. It is better to direct this energy to the development of solutions that will allow everyone to win not in words but in deeds. Peace for everyone and don’t hurt horses. Don’t blame them for the way cavalry uses them.

The First Blockchain Stamp in the World and What is Means

What skills a .NET Developer must have to be successful? “DISCLAIMER: We are not Sponsored by .Net”. The emerging world of IT is bringing up a lot many job opportunities for IT professionals. As Microsoft’s is expanding, we have a number of new tools coming up and even the scope to work with those tools in this constantly widening ecosystem is increasing. .NET development environment Needless to mention that the .NET developers are among the most sought after, versatile and talented within the programming arena. However, just like any other market, the .NET world is also quite competitive. In this broadening field, there is a range of associated specializations and skills. So, if someone is keen to grab the position of a .NET developer in a well-established firm and get paid a handsome salary, then s/he has to fine-tune some of their technical abilities. This way, it gets a lot easier to earn potential and increase their market demand Also Read: Why Big Businesses Prefer ASP .NET Development? # Who is a .NET Developer? Now before giving a detailed view of the key skills required to become a top-shot .NET Developer, let’s understand who is a .NET Developer. The most obvious answer would be someone who clicks on the keyboard and updates the data or someone who creates the whole new world of software. But in reality, the responsibilities of a .NET Developer are far more than this. Also Read: Asp.NET Development and Its Advantage • A .NET Developer creates the applications that are text-based and they are then run on a number of .NET based applications. • A .NET Developer creates the code to access the applications and then the developer helps to resolve system-related errors & defects. • This professional also develops & manages defect tracking system and then s/he settles all the issues by dealing with updating of the system. • S/he makes the risk estimations. • A .NET Developer prepares the policy & procedure documents for running applications. • S/he designs different application system A .NET Developer keeps a constant eye on the system. But this is not it. To ensure these responsibilities are fulfilled well, the .NET developer has to have the below-mentioned skills, which are sought after by every employer in his .NET Developer. # Skills every .NET Developer must possess: Today ASP.NET framework is ruling the web market and it is successfully replacing many other frameworks competing with it. ASP.NET MVC makes it easier for the developers to create robust, feature-rich web applications, and hence speeding up deployment .NET developer must be well-versed with this skill, which makes use of open source web application framework. ASP.NET MVC is being used in the client-side web technologies and easily paired using server-side programming for creating complete software solutions. Not just this but ASP.NET MVC is also useful in doing unit testing. 1) Learn ASP.NET Framework: Points to keep in mind while you hire dedicated .net developers : Visit Here… So, it is quite a known and obvious fact that data dominates the technological world. Hence, having great SQL skills can instantly land you in a job. No matter whether the developer is focused on Microsoft SQL Server or MYSQL, it is necessary to be able to both architect as well as maintain a database as a developer. When the developer is adept at data & data science, it increases the demand and raises the possibility to get a great job as a .NET developer at a great organization. 2) Improve SQL Skills: Microsoft .NET utilizes several databases on its own, but still it is vital for the developer to be knowledgeable in this domain. Even though the system exists but it needs a skilled developer and that is why most employers hunt for one. When a developer is adept with SQL, as well as can deal with the systems like Entity Framework, it adds to his/her portfolio. Hence, this is again a skill that most employers demand in the .NET Development industry. Also, the one who is experienced at handling databases like Oracle and Microsoft SQL get special preference. There are few contemporary apps nowadays that use different NoSQL databases, such as CouchDB or MongoDB. Having skilled at them again makes the developer preferable by the employers. 3) Databases: For a developer, it is essential to be well-versed at creating highly interactive, appealing, and creative web apps. This adds to their market value and also helps in many other ways. This, in fact, becomes an additional quality in the developer’s portfolio, and the more, the better. As per Robert Half Technology Guide, the client-side are the most sought-after skills that add around six percent financial benefit to the initial salary package. Few of the recent technologies that have been added to this list of client-side web development technologies consist of CSS, HTML, jQuery, , and Bootstrap. When the .NET developers are great at these aspects, it adds to their skill. 4) Client-side web development technologies: web development technologies JavaScript This, in fact, is a highly valued, high-rank prestigious program, where the .NET developers work with the Microsoft MVP program, and thus this skill is highly sought-after in the market. Once a developer successful accomplishes this profile status, s/he is considered to become a strong leader with technical excellence in the .NET framework. The .NET developers who have acquired this skill are deemed eligible to play the role of a mentor. 5) Microsoft Most Valuable Professional (MVP): Again the MCSD certification is quite in demand in the market. A .NET developer skilled in this is highly valued as its development & maintenance comes from Microsoft and this requires modification after every 2 years. This is why a developer skilled in this area is again a favorite. 6) Microsoft Certified Solutions Developer (MCSD): in order to become highly proficient in .NET, a developer needs to invest a few years into this framework, to understand the handling and processing well. This way, one gain the required expertise. Look for the projects & opportunities directly involving programming on Microsoft’s platform and conduct further research as well on your own. The good thing is that out there a lot many web tutorials are available to help the developers advance their skill set. Also as .NET is a lucrative skill, hence there is a myriad of enterprises like Itransition that looks for promising new developers in the arena. 7) The more Experience, the better: Much before a developer takes up the task to an app for a big company, it helps them to test out things by first creating their own Windows application. This will help them to get to know first-hand the inherent challenges that come in way of working within the .NET framework. It also helps them to also beforehand what they should expect while entering in big leagues. Other than that, helps in learning to write and edit the code in a simple manner, and you find about your own pace of workflow. 8) Develop your own app: design creating your own app In most cases, the .NET developers are into and hence they are required to possess good communication skills, as they have to regularly communicate with the clients. It is crucial for a web developer to be able to translate the intricate codes into clear-cut features easily understandable to everyone, in order to avoid any kind of misunderstandings. A developer must be confident enough and know to stand their ground on occasions when clients are making unrealistic demands. 9) Should have good communication skills: application development The onlookers for .NET developers are not just satisfied with the theoretical knowledge of .NET, but they are mainly concerned with their skills and what they can practically do with them. There can be a number of .NET developers around you in the market, but it is the skilled ones who are most sought-after in the tech industry. In fact, as there are new technologies being released constantly in the market, hence the .NET developers should be keen to learn more and more, as here learning is an endless process. The more they know, the better it is, and the higher they are paid. Guide to Hire an ASP.NET Developer! : Read More…

Facebook’s Libra announcement and Bitcoin’s 2 times price rise since April once again attract the attention of millions of people. Cryptocurrencies proved to be not only the result of blockchain revolution but also the source of passive income. I’m not going to tell you about buy and hold strategies and things you may already know, rather than tell you about services that allow making money on crypto in different ways. So, here we go! Tokpie For almost anyone in the crypto sphere, there is no breaking news about bounties existence. People earn money by making microtasks. But the big deal is a service that provides for its users. Tokpie It allows bounty hunters to sell bounty stakes for Ethereum of different projects on Tokpie exchange immediately as soon as stakes appear on bounty spreadsheet. In comparison, usually, it takes months for bounty hunters to receive the deserved reward. In such a way Tokpie saves time for people and help to avoid the risk of wasting time for zero bounty rewards. WhatToMine Bitcoin price, as I mentioned, is going up, and so do altcoins prices. It also impacts in a positive way the revenue you can get from mining. is absolutely the most popular service that helps you to choose what exact coin is better for mining in term of future profit. The service is so popular, that according to Similarweb, top service to website traffic adjustment, WhatToMine have 4.7 million visits per month — this is huge. WhatToMine Using WhatToMine, you can check how profitable it is to mine selected altcoins in comparison to Ethereum or Bitcoin. Earn.com This service (now owned by popular crypto exchange Coinbase) has made it possible for the masses to use digital currencies such as BTC to send and receive targeted, paid microtasks. was formerly known as 21.co. Earn.com The idea of their service is simple and targeted on providing people the possibility to earn Bitcoin by replying to emails and completing tasks.

Top Industries Getting Revolutionised by Artificial Intelligence

The first decade of the existence of cryptocurrencies was everything but lacking events and novelties. The count of “live” cryptocurrency projects has exceeded 2000, with at least an another thousand announced. The number of holders of cryptocurrencies is estimated to be at the end of it. between 13 and 25 million Starting with Satoshi’s “A Peer-To-Peer Electronic Cash System”, the use cases for cryptocurrencies have extended, diversified, wandered astray, becoming — especially during the beginning and the bloating of the ICO bubble — mainly means to make a few quick bucks on pompous marketing of white papers and LinkedIn profiles. Several exposed scams and the loss of the vision presented in the Satoshi paper ultimately lead to the burst of the ICO bubble, several months of continuous loss of value of the total market capitalization of the cryptocurrency market, regulatory pressure in certain (financially significant) countries and the discontinuation or cancellation of many announced projects. The decade of infancy, in spite of providing a number of solutions and improvements through dialectics, still didn’t manage to provide long term solutions to at least three re-occurring problems of crypto, that will have to be solved before the crypto-sphere reaches the Crypto V.3 stage and succeeds in eventually becoming the borderless, decentralized, immutably reliable, censorship resistant and accessible to all electronic cash of the future, growing out of what it is today — a tradable asset, valued through the amount of fiat needed for its’ purchase. The three core problems of crypto that have to be solved in the quest to find the sound money of the future can be simplified into: sustainability of cryptocurrency mining, (de)centralization and mass adoption. Sustainability The sustainability problem of cryptocurrency mining has been observed from the moment Proof Of Work (PoW) mining became a business. The emergence of PoW mining farms, built on power-hungry ASICs and arrays of GPUs brought the concern of electricity consumption and the adverse environmental effects it has. While last year’s decline in Bitcoin price reduced the number of miners, and consequently the total Bitcoin electricity consumption, its’ price recovery has brought the . With the awareness of the detrimental effects of PoW mining to the environment in the long run, more and more blockchains introduce the Proof Of Stake (PoS) as their main consensus algorithm to forge blocks. While the PoS consensus requires, no doubt, significantly less power, it introduces — or doesn’t help to solve — the problem of centralization. total back up to being close to the electricity consumption of the Czech Republic (De)centralization The biggest novelty brought by the cryptocurrency paradigm is in fact decentralization — as opposed to the centralized governance of conventional monetary systems, . Initially, PoW miners enabled high decentralization, but with the accumulation of hashing power of mining farms, mining pools have also grown, which all together increases the risk of centralization of mining resources. it hands back the control to the “user” — i.e. the network, which by means of consensus validates transactions and maintains immutable records Bitcoin mining pools share on June 29h, 2019. (Source: ) https://www.blockchain.com/pools With PoS cryptocurrencies, the risk of centralization is a given — the concept of staking distributes rewards for block forgers proportionally to the amount at stake, and with low initial distribution, it doesn’t take too much mathematics to calculate how quickly the network becomes centralized and at risk of a “takeover” — a 51% attack. Mass adoption The low adoption of cryptocurrencies as means of payment for purchased goods or services rendered is the result of globally low number of cryptocurrency holders and their mindset that makes cryptocurrencies an investment vehicle rather than a currency for daily use. A part of reasons why the adoption remains low in spite of the large number of cryptocurrencies available is in the primary distribution — crypto is either obtained by mining or by taking part in ICOs, both of which are available to those who can afford/access them. Secondary markets, even though they are at times very lively, are again accessible to those that come from countries eligible to pass KYC procedures and to those who have enough excess funds to invest in the super-volatile cryptocurrency market. As long as the access to cryptocurrencies comes at a cost measured and paid for in fiat — such as e.g. the price of building a PoW mining rig or buying cryptos in exchanges, the main use case of cryptocurrencies will remain “investment”, as the holders expect to cover their initial investment and make a profit in fiat, before they are ready to transact with the cryptocurrencies they have. Why Proof Of Capacity? Energy Efficient The Proof Of Capacity (PoC) consensus algorithm has been around since 2014, after it was introduced as the base protocol of the Burst blockchain. The resource used to mine blocks of PoC cryptocurrencies is storage space, where miners store pre-computed hashes — plot files. Every time a block is mined, miners read plot files from hard drives, searching for deadlines computed from stored hashes, which is then submitted to the pool or the wallet. The lowest deadline submitted to the network forges the block. Given that the operation of hard disks requires considerably less energy (5–10 W), the processing on one transaction on the than the processing of one Bitcoin transaction by several orders of magnitude (~100.000). Burst blockchain uses less electricity Enabling And Promoting Decentralization As storage space comes with any computer or handheld device, anyone having unused space on their computer, laptop or even mobile phone can create a plot file and start mining a PoC cryptocurrency, without the need to purchase additional devices or equipment. The electricity consumption of PoC mining is, in fact, so low that running the on Android mobiles doesn’t impact the user-perceived duration of the mobile’s operation on one battery charging. Scavenger miner <a href="https://medium.com/media/e631afd8bc972965a011a5a853132506/href">https://medium.com/media/e631afd8bc972965a011a5a853132506/href</a> Since the PoC consensus algorithm has been deployed, the PoC plot file has been improved from the PoC1 to plot format, by the (PoCC), an anonymous developer group focused on the development and the improvement of PoC technology. PoC2 is the current standard plot file format for existing PoC cryptocurrencies. The PoCC recently went one step further in optimization of PoC mining, by introducing , that doubles the effective mining capacity of PoC miners by “compressing” hashes. the optimized PoC2 Proof Of Capacity Consortium the revolutionary Helix plot file format Even though the Helix requires a GPU on the mining system, the total energy consumption of the mining process is lower than with HDD-only setup of equivalent capacity. The innovation has been introduced with the intention to “level the playing field” between big-professional miners that operate miners of up to several petabytes and hobbyist-enthusiasts who mine PoC coins with less hardware, and thus slow down or prevent the centralization of mining resources on PoC blockchains. An another evolutionary step for PoC, the prototype of which has been prepared by the PoCC is the PoC3 plot file format, that allows for data other than hashes to be mined. The PoC3 concept uses individualized plots, that will contain “the knowledge of mankind” — documents, encyclopedic material and files, which PoC miners will be able to mine. The current efforts regarding PoC3 are focused on creating a list of relevant files to be used for mining in the future. PoC3 mining addresses smaller mining setups, by enabling them to increase the profitability of their mining operation by taking part in this philanthropic project. Image courtesy of https://starburst.pink/post/scavenger-mining-android/ Accessible To Everyone The technological improvements that have been and are being introduced into the Proof Of Capacity ecosystem grant access to cryptocurrencies for more people than any other paradigm within the crypto-sphere. Given that the number of mobile phones used across the globe already exceeds the number of people, it is a question of mobile appstore policy changes before running mobile crypto miners is a “normal” thing to do. With the Helix and PoC3, the entry barrier into the primary cryptocurrency market is also being substantially lowered. Having more holders of cryptocurrencies — increasing the geographical “density” of them actually, is likely to encourage the business adoption of cryptocurrencies as well. If one thinks about it — in case there were 100 crypto-holders in a neighborhood, the owner of the local coffee shop, deli or kiosk would have a greater interest to start accepting crypto as payment than when there’s no more than one or two occasional customers that are willing to use their crypto as money. In that way, the business adoption of crypto could be pushed not just by companies driving cryptocurrency projects — which is the current case, with projects striving to create “partnerships” with different businesses, but also from the layer of consumers. Until now, the PoC layer of the world of crypto has been represented only by Burstcoin. Other coins using the Proof Of Capacity have started to operate only late last year, with several others announced for the future— such as Chia and Diskcoin. It is likely that other projects based on the Proof Of Capacity consensus will soon emerge — given that there are attempts, , to issue PoC cryptocurrencies. some of questionable nature With the technological improvements introduced in the past year within the PoC ecosystem, that strive to make cryptocurrencies accessible to many — regardless of how much or little they can invest into mining equipment and regardless if they can access secondary cryptocurrency markets, it is just possible that the future in which one can buy their morning coffee on their way to work using the money their mobile phone mined during the night is not too distant. <a href="https://medium.com/media/3c851dac986ab6dbb2d1aaa91205a8eb/href">https://medium.com/media/3c851dac986ab6dbb2d1aaa91205a8eb/href</a>
