Hey everyone! and just like you, I’ve been fascinated with the recent progress of artificial intelligence. Realizing that I needed to stay abreast with all the developments happening, I decided to embark on a personal journey of learning, thus was born! With this series, I will be learning about LLMs and share ideas, experiments, opinions, trends & learnings through my blog posts. You can follow along the journey on HackerNoon or my personal website . In today’s article, we’ll be looking at the case study of how Klarna leveraged Gen AI and what other companies can learn from it. , I’m Nataraj 100 days of AI here here How is Klarna using generative AI? There are lots of ways generative AI is being used by companies, and we have explored some of them . In case of Klarna, they launched an AI customer support assistant that is available 24*7 and supports 30+ languages. They launched the assistant using Open AI as their LLM provider. If we have to guess, they have finetuned it using their own customer support interaction data set that they have collected over the years. in a previous post What features does the Klarna AI assistant support? The assistant is designed to handle wide range of questions related to refunds, returns, payment-related issues, cancellations, disputes, and invoice inaccuracies, ensuring swift and effective solutions. Like any tech feature, its available 24*7 across all geographies. For customers who want to know what they can afford and not afford, it also provides info related to purchase power, spending limits and the reasons why it exists. All the info of a customer account is with the assistant to help any questions related to it. Is the new AI assistant effective? Its cool to say that we have used gen AI and see the stock pop up, but the real question is, does the feature deliver value to the company. And from the numbers, it looks like it is beating expectations. Here are some of the numbers. Two-thirds of all customer service chats are handled by the assistant, which is an impressive 2.3M conversations. Customer satisfaction same as human conversations. 25% drop in repeat inquiries Estimated to drive $40M in profit improvements to the company. What are the takeaways from Klarna’s gen AI assistant? Its clear that generative AI is being adopted and creating value for companies at all stages. Customer support will get more effective and cheaper. If the new assistant is handling two-thirds of all conversations, it means the next set of companies which start their customer support teams will not require the same number of people in their teams. And this also means the existing customer support teams might be larger than needed. We will see a lot of growth stage startups follow Klarna to boost their profitability and reduce expenses. For companies like Klarna whose stocks are down due to the concern of profitability, companies with similar concerns will start to look at leveraging AI to cut costs and boost profitability. Open AI’s board drama didn’t effect its trust among companies to use them for production scale deployments. When Sam Altman was fired and re-hired at Open Ai, one of the concerns was that this would reduce the trust among developers to use Open Ai to create AI applications. When a large public company publishes such a case study its clear that the board drama at Open Ai didn’t effect Open AI’s abilities. Expect more companies to announce improvements because of using gen AI technology in fields outside customer support. More case studies using generative AI will come from more public companies showing how they are leveraging Ai. This is a function of every company wanting to get a piece of the AI narrative and the fact that gen AI features are actually delivering on value. If you are a company with large data set related to customer support, you should explore creating an AI assistant for support interactions. That’s it for Day 19 of 100 Days of AI.

MR. KIRKPATRICK, Q.C.

Mrs. Kirkpatrick had been reading aloud till Lady Cumnor fell asleep

In an insightful and interesting Q&A conversation, Hackernoon contributor Brian Wallace interviews Nachum Kligman, co-founder & CEO of Book Like a Boss, an online booking platform. #1. What do you currently do and what’s your favorite part about it? I am the co-founder & CEO of Book Like A Boss, a booking platform that makes it simple for anyone to sell a service in less than an hour. We launched in 2017 and have tens of thousands of users in over 100 countries. My favorite part is when we get unsolicited 5-Star reviews from our customers or when I’m on a Demo with a customer and they just say “Wow”. It makes all the hard work and challenges worth it when you know you are having a positive impact on a person and their business. #2. What are you currently excited about at BLAB? We recently announced the launch of our Enterprise Product. We launched as a solution for individuals and in 2021 we released our company plans for those with medium sized businesses from 3-300 employees or sales reps. We have now released the ability to white label and blend into other existing platforms and can handle from 5,000 to millions of users. With this launch we also announced a partnership with Duda, a leading Website Builder with over 20,000 Agencies as customers and powering more than a million active websites. You can now turn any Duda website into a booking system for appointments, memberships, selling services, events and more. You can read more about that : here #3. How did you get started with your Tech Career? My first tech experience was an idea I had back in 1998. It was my first start-up, a company I called FunRaze - The Fun Way to Raise Money. It was a platform that enabled companies to donate products to a charity of their choice. They would receive free publicity and a tax write off for their donation. We would then post the item on our site where anyone could put in $1 or more depending on the item and at the end of the auction we would randomly choose a winner from everyone that entered. We would take a 15% platform fee for every auction and it was the perfect win/win/win situation. I had celebrities lined up to get involved and raised some initial funds and had a large law firm taking care of all the legal work for a percentage of the company. Unfortunately, after 4 months, the law firm told us the bad news and that what we were trying to do was illegal and considered gambling. We would need to get a license for every county in every state for every auction, basically an impossible task. This was 25 years ago. I was shocked back in 2012 when Omaze was the first to introduce what I tried to do back in 1998. The way they got around the legal issue was that they had a way for anyone to enter any of their auctions for free without needing to purchase a ticket. They way the government couldn’t call it gambling if you could enter for free and only pay for additional tickets or because you wanted to. I didn’t think this was a good business model and it seems they are having some issues now in the USA. #4. Tell us more about the things you write/make/manage/build! I love taking ideas from nothing and bringing them to life. In 2002 I started an Interoperable Instant Messaging company called IMVITE. I was the first to put an RSS feed into a messenger and created a built-in mall with a built-in affiliate program. I left in 2005 over a disagreement with my partners. I wanted to take our messenger and integrate with our own Social Network. My partners didn’t think Social Networking would be anything so I left. I then started a company called Qoof, a video shopping player. There are 4 technology patents in my name for coming up with the idea to put overlays on top of videos. I left in 2010 when an investor gave me an ultimatum, either allow him to buy 85% of the company for $500k (there was a downturn in the markets and we needed funds) or fire my 12 employees and close up shop. I sold my shares and was left with less than 4%. So I left the company after saving them and the company later exited under the name Viewbix based on my ideas to turn the company around. Then I had a few more projects as most good entrepreneurs, mostly failures with a couple of successes until I came up with the idea for Book Like A Boss at the end of 2015. I pitched my partner on the idea and we launched in June 2017. It’s been my biggest success to date and has been mostly bootstrapped with tens of thousands of happy users all around the world. #5. What’s your favorite thing about the internet? It’s probably what everyone would say, but the truth is the ability to keep in touch with old friends and family is unparalleled. The ability to share videos, photos or just a simple hello to let people know you care is something that was not so simple 20 years ago. Now with a click of a button you can share your children’s birthday party pics with your family all over the world. #6. What is your least favorite thing about the internet? Definitely the addiction. There is always another email, another message, another article, another customer service ticket waiting to be answered etc.. I try to get back to people as fast as possible, especially to my employees who are waiting for answers from me. I find it hard to just totally turn off my phone for deep work or even for family time. I’m getting better at it, but I still look back at quieter times when you actually had to speak to someone in person and you would be able to give your undivided attention. #7. If you were given $10 million to invest in something today what would you invest in and why? Is it cliché to say my company? Lol. Truth is there is a HUGE game changing project I would like to do that involves AI and the way we communicate with those we need. I don’t want to say more right now, but I hope to break ground on this project in 2023. #8. What’s something you’re currently learning or excited to learn? I’ve been following the online newsletter industry for about a year now and I love the new software companies (shoutout to Beehiiv) that are coming out as well as the courses and newsletters about newsletters. I don’t have the time to start one right now, but I do love picking up tips and seeing how people are becoming successful. It’s all in the list! #9. Would you rather travel 10 years into the past or 10 years into the future? Give reasons for your answer. For sure 10 years in the past. Everyone wishes they could change something from their past that would create a brighter future. Why go 10 years ahead and miss out on things you could have changed as well as all that time spent with loved ones and friends.

Pioneering Online Bookings: A Talk with Nachum Kligman, CEO of Book Like A Boss

So let’s start! Tell us a bit about yourself. For example, name, profession, and personal interests. I'm Kirill Balakhonov, working at Chainstack.com, a leading Web3 infrastructure provider. As the Lead Product Manager, I specialize in our recently launched product, Chainstack Subgraphs hosting, which focuses on blockchain data access and indexing. Prior to this role, I spent five years in the Data Science field, where I developed and trained various computer vision neural networks and large language models. I have a strong passion for exploring new technologies, programming, and prototyping everything on my own. I adore my family, which consists of my wife, a 5-year-old son, and a pug dog. Interesting! What was your latest Hackernoon Top story about? It was the first part of a three-part series called " ." This series came after years of developing telegram bots solely for my own usage, which proved to be very helpful in various cases. I am truly inspired by the idea of having a group of intelligent helper bots that can handle certain tasks on my behalf. How to Create a Telegram Bot to Monitor Your Service Uptime in Python (Part 1: Instant Metrics) Although I can't recall all of them, there were some exceptionally useful bots that continue to assist me in my daily life. They read numerous telegram channels and only send me the most interesting and relevant content. Additionally, I have several personal ChatGPT-powered telegram bot assistants, a news navigator bot, pet projects alerting&monitoring bots, and bots for sharing community links, amongst others. Do you usually write on similar topics? If not, what do you usually write about? I write a lot about programming. I really like the format of zero-to-hero tutorials because I always learn best using this type of material, considering it the fastest approach to learning anything. Additionally, I write about Web3/blockchains/smart contracts development, which is also my top interest in the technological business field. Great! What is your usual writing routine like (if you have one?) Usually, I write about a project that I have just implemented to showcase my work and share the results with the developer community. The routine is simply to describe something that I have had experience with. Being a writer in tech can be a challenge. It’s not often our main role, but an addition to another one. What is the biggest challenge you have when it comes to writing? The biggest challenge for me is finding time to write after I come up with an article idea. I have so many ideas in my head that I can't possibly put them all on paper, as it would take up a significant amount of time. What is the next thing you hope to achieve in your career? To be honest, I'm not really focused on career goals. The main thing for me is to have an interesting time and the opportunity to develop myself. Wow, that’s admirable. Now, something more casual: What is your guilty pleasure of choice? I love walking, eating delicious food, and spending time with friends. Do you have a non-tech-related hobby? If yes, what is it? I love snowboarding, traveling, and watching TV shows. What can the HackerNoon community expect to read from you next? It would be great to write more about the real development of decentralized applications in simple language, from a first-person perspective, and for beginner developers. Web3 is an area that fascinates me from various angles, as a creator of developer tools, interesting and useful content, and as an avid learner of new technologies. What’s your opinion on HackerNoon as a platform for writers? This is an excellent place to study, learn new things and share experiences. Thanks for taking the time to join our “ ” series. It was a pleasure. Do you have any closing words? Meet the Writer Thank you for such a wonderful platform!

And of course, it helps a lot for all people that are looking through the internet for a solution to such problem. So please, if you’ve learned something new - right an article about it, cause it probably helps the next engineer to find the answer faster!

Meet Noonies 2022 Winner Georgii Kliukovkin of the Category Functional Programming

On September 15, 2022. Ethereum, the second largest crypto in the world, successfully transitioned from proof-of-work (PoW) to a proof-of-stake (PoS) consensus algorithm via the Merge update. This transition has sparked a lot of debate about the pros and cons of these algorithms. This blog will take an unbiased look at both PoW and PoS. What is PoW? Governance is simple in a centralized ecosystem – you have a central board of directors or a CEO making all the big decisions. However, how do you implement robust governance in a decentralized model? You will need to trust the participants to consistently do a good job. However, any model that relies on “trust” can’t be that efficient and reliant. Plus, seeing how crypto protocols deal with millions and billions of dollars, it is even more crucial to have a trustless and robust governance process that can be easily replicated. In particular, Nakamoto wanted an algorithm that fulfilled the following criteria: The consensus process itself should be really tedious. Proving that you have reached the correct conclusion using the consensus should be simple. Successful participants should be rewarded for their efforts. Malicious participants must be punished for working against the protocol. Last but not least, the algorithm must provably solve double-spending. Double-spending is an issue where the same crypto coin can be spent on two (or more) completely different transactions simultaneously Keeping all these in mind, Nakamoto devised a consensus mechanism called proof-of-work. This is how the algorithm works: Users wishing to participate in PoW must buy mining equipment like GPUs and ASICs. The users, aka “miners,” will then use their GPUs and ASICs to solve cryptographically-hard puzzles. If they can successfully solve this puzzle, they get the right to add a block to the blockchain and earn block rewards. Before adding the block, the miner must propagate their block throughout the network to validate their work. The act of block validation (or “showing proof of your work”) is relatively straightforward. Miners use real-world computational power and electricity to participate in the mining process. The degree of difficulty of the process is directly related to the number of active miners in the protocol. The overall cost of mining is also directly related to the difficulty of the process. How PoW Prevents double-spending? As we mentioned earlier, preventing potential double-spending attacks is one of the core functions of PoW. So, what is a double-spending attack? What you see in the diagram above is a “fork,” basically a split in the chain. So, a user can potentially spend the same coin in the main chain and the forked chain. As you can imagine, this could cause massive confusion. Think of it like this. Imagine that you spent your BTC buying a house in the blue chain and the same coin purchasing a car in the red chain. Which one of these transactions should go through? For malicious miners who may look to discredit Bitcoin, creating random forks and deeming the majority of the transactions completely useless may be the best way to go about it. So, does PoW completely negate forks? No, it doesn't. However, PoW makes forking extremely expensive and impractical. For example, if a malicious miner decides to take over the Bitcoin blockchain through a fork, it will be challenging for them to do so against the combined might of the rest of the miner network. To do so successfully, they need to have control of over 51% of the network’s mining power (or hashrate). This is also known as a 51% attack. When an entity has control of over 51% of the network hashrate, it can basically create multiple random forks and rewrite the entire system. However, in a PoW system, it becomes exceedingly expensive to conduct a 51% attack. For example, in Bitcoin, it costs ~$750,000 to conduct a 51% attack for just 1 hour. But PoW has a big problem PoW’s biggest problem is that it is inherently extremely wasteful. Check out this chart: Bitcoin consumes more electricity than Noway and Bangladesh! However, what about its carbon footprint? Now, what about its carbon footprint? As per reports, Bitcoin is responsible for annually! That’s the same as countries like Jordan and Sri Lanka. This wastefulness of PoW has attracted a lot of negative criticism. This is why several protocols have started opting for proof-of-stake (PoS), a significantly cleaner alternative. 22-22.9 million metric tons of carbon dioxide emissions What is PoS? Proof-of-Stake makes the mining process completely virtual. In 2012, Peercoin became the first coin to implement PoS. Following that several other cryptocurrencies like Cardano, Algorand, and, most famously, Ethereum followed suit. Each coin has its own unique implementation of PoS. However, for your understanding, let’s give you a simplistic overview of the entire process: Instead of buying ASICs and GPU, you need to lock up a certain amount of tokens as a “stake” within the system. Your “mining power” depends on the amount of stake you lock up within the protocol. The more stake you have, the more your chances of validating a block and getting a block reward. While traditional PoS isn’t exactly faster than PoW, it simplifies the integration of scalability techniques like sharding. The entire process is virtual and doesn’t require you to waste resources. Ethereum Merge and PoS On September 15, 2022, Ethereum deployed the Merge update and transitioned from PoW to PoS. Ethereum’s staking algorithm is called Casper, and its signature feature is the “slashing mechanism.” Slashing is how Ethereum prevents the blockchain from forking. To participate in Ethereum’s PoS, you must stake at least 32 ETH, which is a significant amount. Furthermore, if you act against the system and attempt to fork the chain, your stake will get slashed, meaning you will lose a substantial amount of your own money. This has been designed to ensure that the validators are economically incentivized to always act in the system's best interests. However, like most PoS algorithms, Ethereum’s Casper also has a significant weakness. The biggest problem with PoS The biggest problem with the majority of the PoS algorithms is their overdependence on just one token. This leads to the following issues: The system favors early adopters who may have gotten a big bag of native tokens for cheap. Being dependent on a “stake-as-trust” system could have protocol-breaking implications in a cross-chain ecosystem. Let’s say you transfer BTC from Bitcoin to Ethereum to access certain DeFi apps. If the value of BTC is higher than the stake, then the validator is incentivized to act maliciously. How KIRA mitigates these issues with MBPoS native consensus stands for “Multi-Bonded Proof of Stake.” With MBPoS, you can stake multiple assets simultaneously and participate in the consensus process. With MBPoS, you may stake real-world assets like fiat and commodities and popular crypto assets like BTC, ETH, DOT, and even NFTs. The revenue generated can be shared among all your staked assets, increasing the value proposition of each token. KIRA's MBPoS Here’s a quick overview of MBPoS: By enabling the staking of multiple assets, KIRA resolves potential trust issues. MBPoS guarantees transaction finality and fast block times. By allowing multiple tokens, MBPoS creates a fairer system that doesn’t overtly reward early adopters.
