DoxyChain

doxychain

HackerNoon Reporter: Please tell us briefly about your background. I’m Co-founder and CEO of DoxyChain and winner of the Forbes 25 under 25 award. I’m member of the Global Shapers Community, an initiative of the World Economic Forum. Previously, I worked for the Warsaw Stock Exchange in the WSE Private Market project - a market for tokenization of assets using blockchain technology. Also took part in several deep tech projects in Poland and Singapore, among others. I’m also member of the former working group in the Polish Ministry of Digitalisation on DLT and blockchain. What's your startup called? And in a sentence or two, what does it do? DoxyChain. It is a next-generation blockchain document management software (DMS). Powered by its own blockchain, DoxyChain is an innovation that combines electronic signature, workflows optimization, and enhanced security, which means we are the very first user-oriented holistic digital solution. We democratize blockchain and set new standards for digital documents space. What is the origin story? DoxyChain idea emerged during the GlobalLegal Hackathon held in Warsaw Google Campus at the beginning of 2019, where the four future co-founders Gabriel Dymowski, Piotr Żelazko, Marcin Lorenc, and Daniel Bigs, received the award for their "Blockchain Power-of-Attorney" project. After that competition,, the team received multiple inquiries and questions about the solution's functionalities and availability. That became an indicator of the market trust for a blockchain-based solutions. Yet before the entity was set up in September 2019, the team ran various business, legal, tech checkups to explore the market pain points, opportunities, risks and shape the revolutionary platform. Verified by the Covid-19 pandemic, the market needs happen to be way wider than just a PoA, which made the team start working on the app for all the documents (including various contracts), digitization, and management. After several MVP implementations and assumptions checks, DoxyChain launched their platform in Q2 2021 in Poland as B2B SaaS, also addressing the needs of enterprise clients with a dedicated offer for them. #What do you love about your team, and why are you the ones to solve this problem? Some of the core founders know each other for more than 7 years. We share a passion for technology and disruptive solutions. We are not afraid to be different, and we are not afraid to be judged for our revolutionary ideas. The experiences of every team member complement each other. We have a talented lawyer, 2 blockchain geniuses, and a business growth hacker. We communicate openly, know our strong and weak spots, listen to the more experienced advisors, and learn every day. We bring the next-gem solution to the market, and we are sure we are doing the right thing. If you weren't building your startup, what would you be doing? If we weren't building the DoxyChain startup, we would be building another tech-related project. All of us have a strong entrepreneurial spirit. Analytical and critical thinking help me spot the pain points and come up with ways to resolve those. All of us would be connected to the blockchain market one way or another. #At the moment, how do you measure success? What are your core metrics? Basically, we have just launched. The 3 main metrics crucial for us are the number of users, market awareness about DoxyChain, and partnerships/network. What's most exciting about your traction to date? It took us a while to test the platform before going public with SaaS. However, we already have 25+ paying SMEs. Besides, our resell partners are what we are most excited about: Wolters Kluwer Poland and Oracle for Startups among them. What technologies are you currently most excited about, and most worried about? And why? Mostly I am excited about blockchain since I have been in that market for a while now. Obviously, every technology has pros and cons. The question is what the balance is. I personally took part in a debate, "Does blockchain bring more harm than good?" and although the end result was "No," I listened to several good arguments about DLT cons. There are risks. The approach we take in DoxyChain is that we try to foresee those and make them part of our development strategy. What drew you to get published on HackerNoon? What do you like most about our platform? The content quality and transparency are what I like about HackerNoon. Real market stakeholders write stories and their messages are super meaningful to other industry participants. The tech focus is also a reason why I like you, guys! What advice would you give to the 21-year-old version of yourself? Buy crypto :D I think the advice would be to make as many valuable connections as possible because network really matters and to continue humbly to pursue your goal no matter what. What is something surprising you've learned this year that your contemporaries would benefit from knowing? Hard work really pays off, be patient and trust the process. Vote for DoxyChain as the . startup of the year, Warsaw, Poland

The Ultimate Dev Stack for Building on Bitcoin
Building a Decentralized Application on Rootstock 1. What is your smart contract designed to do? My hybrid smart contract is designed to tap into Chainlink's Price Feeds on Rootstock to get real-world asset prices. This is particularly useful if you're building DeFi applications that need reliable price data. 2. Why deploy on Roostock, what benefits does the platform offer compared to alternatives? Because Rootstock, being merge-mined with Bitcoin, inherits its unparalleled security model while maintaining full EVM compatibility. This means I can leverage the entire Ethereum development ecosystem while building on Bitcoin's foundation. Moreover, if also add Chainlink's oracle network to the mix, I suddenly have the ability to create a smart contract that can interact with real-world data and systems. 3. Break down the key components of your smart contract i.e state variables, functions, events, etc Smart Contract RootStockPriceFeed.sol SPDX-License-Identifier: MIT Imports State Variables Constructor Functions Key Points The contract relies on an external Chainlink oracle for price data, making it a hybrid smart contract.
The getLatestPrice() function is marked as view, meaning it doesn't modify state but only reads from the oracle.
The contract assumes the Chainlink oracle is already deployed and has the correct interface implemented. 4. How did you test your smart contract? Did you notice any vulnerabilities while testing? If so, what were they and how did you correct for them This is a proof-of-concept(POC) and since I am using the Chainlink battle-tested AggregatorV3Interface.sol contract but with no offical price feed contract address for RootStock on Chainlink https://docs.chain.link/data-feeds/price-feeds/addresses, I tested my RootStockPriceFeed.sol using a depolyment script to do a staging test on the RSK Testnet using my own public address “0xEd752dCE9f6c1Db35FeDABca445617A0d2B0b674” 5. What steps have you taken to keep your smart contract safe? Eventhough there was no need to do an official audit of my POC, I used one of the most popular static analysis tools to do an audit to ensure safety of my hybrid smart contract using: Slither. The output color codes potential issues: Green - Areas that are probably ok, may be informational findings, we may want to have a look
Yellow - Potential issue detected, we should probably take a closer look
Red - Signifant issues detected that should absolutely be addressed. 6. Share, step-by-step, how you deployed your smart contract on Rootstock. Before we dive into the technical details, make sure you have Node.js and nvm version manager for node.js installed on your system since we'll need it to install and use Node version v18.0.0 that is compatible with Rootstock starter kit. You'll also need Hardhat and a basic grasp of smart contracts with Solidity and JavaScript/TypeScript. You'll also need a Metamask wallet configured for the Rootstock network and some test RBTC if you're planning to follow along. Let's start by setting up our development environment. First, we'll clone the Rootstock Hardhat Starter Kit, which provides a solid foundation for our project: Now, let's install all the required dependencies: Let's rename our project directory to better reflect its purpose: We'll need to modify our package.json and package-lock.json to reflect our project's new name and add Chainlink specific dependencies: After installation, add the plugin to your Hardhat config: The magic happens in our configuration setup. We need to tell Hardhat how to work with both Rootstock and Chainlink. I've found that keeping this configuration clean and well-organized saves countless hours down the line. Update your hardhat.config.ts file: Don't forget to create a .env file to store your sensitive information: Next, let's test our RootStock configuration, but first make sure you have sufficient Testnet RBTC funds available on your Metamask wallet. You can get some from a Rootstock Testnet Faucet. Then, let's deploy the contract. We'll use the --tags flag to only deploy the MultiToken 1155 contract. Output: Next, let's test our Chainlink confirguration to get a list of all available getter-method for a specific registry Output: Now, let's build something practical - a smart contract that taps into Chainlink's Price Feeds on Rootstock to get real-world asset prices. This is particularly useful if you're building DeFi applications that need reliable price data. Here's what that looks like: To bring our contract to life, we need a deployment script. Create scripts/deploy.ts: Finally, let's deploy our hybrid smart contract to the Rootstock RSK Testnet by running the deploy script: Output: 7. What did you learn from your deployment experience? What worked well, and what would you change the next time around? The magnificence of combining Rootstock with Chainlink through Hardhat is that it opens up a world of possibilities. You're not just building smart contracts; you're given the opportunity to creating secure, Bitcoin-based applications that can interact with real-world data. The security of Bitcoin's network, the flexibility of EVM compatibility, and reliable external data through Chainlink oracles - it's a powerful combination that's greater than the sum of its parts. This simple contract demonstrates how to create a hybrid smart contract that leverages off-chain data (via Chainlink) to provide on-chain functionality (retrieving asset prices) on RootStock. All worked well, with some warnings after a quick audit using Slither static analysis tool and next time around I will do a few changes: Use of internal variables for interacting with other contracts.
Proper error handling could be added to deal with potential issues when calling latestRoundData().
Consider adding events for important state changes or actions taken by the contract.

Deploying Hybrid Smart Contracts on Rootstock

In the bull market, when BTC goes up and breaks its all-time high (ATH), the accumulation process for a new ATH is underway. This is good for altcoins, which go up next. SOL and ETH are the first altcoins to start moving, just like many other Layer 1’s. Investors are looking for ways to maximize their returns on ETH because of gas fees and exploring alternative options, which brings us to Layer 2. Projects like BASE & ARBITRIUM, DOGECHAIN, OPTIMISM, POLYGON, and others that are built on ETH are starting to grow too. Once these altcoins start to gain traction, investors start looking for ways to diversify their profits. Things started to change this year. Once ETFs were approved for BTC, altcoins didn't see much growth. They rarely took off. While some meme tokens saw huge gains (up to 10x), altcoins tried to triple their value and then fell back to their original levels. The same thing happened again after the second big spike, this time with an ETF for ETH. Once again, while ETH peaked, altcoins stayed at the bottom. And yes, meme tokens were making waves again. Crypto wallet activity is at an all-time high, and it is still on the rise. Over the course of the year, it has tripled, compared to previous cycles that saw a tenfold increase. I'm seeing the greatest increase in wallet activity on Solana and Base. This suggests that the alt season hasn't started yet, and could indirectly confirm the BTC supercycle theory. The rise of decentralized launchpads has been a major driver of the growth of these networks. You don't need to know any coding to create a token. But launchpads have some technical limitations, they're great for creating template tokens. It's worth noting that the only category of template tokens that can attract a large community are meme tokens! That's why the most successful and first Launchpads is based on Solana and was designed to run meme tokens. Solana is where a lot of memes started. Is that just a coincidence? It's not a coincidence. It's a trend. Many memes launched on pump.fun are later launched as analogs on other networks, where some of them become more successful than the original projects. The second most popular moonshot launchpad from dexscreener also started on Solana and now supports Base. ETH saw little change in developers’ activity from year to year (though it's still the leader in this area). BTC and its L2s, on the other hand, have seen a significant increase in development activity, doubling in the past year. This growth is likely to continue and set new trends in the coming year. To avoid confusion, I will refer to the new Meme tokens currently trending in the short-term market as "Memes 2.0". There are several differences between Memes 2.0 and Meme tokens from previous cycles. The main difference is how the tokens were launched. Memes 2.0 launch on launchpads using the Bonding Curve, which we call a fair launch. What makes this launch different is how the tokens are distributed after they're listed on the dex. Specifically, only a small percentage of the supply is available for purchase in the liquidity pool. This means that if you try to sell a large number of tokens, the price will drop dramatically. In fact, 99.999% of these tokens going to 0 after being listed on dex. This is an important point. I like to think of this as natural selection. If meme 2.0 has a strong narrative and a healthy community by the time when whales and/or developers are out, a CTO (community token owned) is created. The community takes ownership of the project's development. With a strong community, the project is already more likely to succeed than at the Bonding Curve level. A short-term speculative meme 2.0 can become a long-term meme. So the main things that differentiate memes 2.0 from those of previous cycles are how popular the CTOs are, how the tokens are distributed, and how they're launched. Some good examples are GOAT, Michi, FWOG, and MOODENG. On top of that, memes 2.0 have become a kind of tokenized representation of everything that happens in the world. It's like a news channel. If you want to see what's trending, just go to pump.fun and look at the top active tokens :) Murad's theory of the memcoin supercycle suggests that we may soon see a cycle in which memcoins surpass traditional coins. This will be based on community sentiment, emotion, and the speculative lure of getting rich quickly. Memcoins are different from traditional projects because they grow through hype and the ability to rally large communities. The main things to watch out for are: The popularity of meme launchpads (pump.fun, moonshot) and the fact that you can deploy memtokens almost for free without any programming skills or blockchain knowledge.
Many moonboys on X and other socials
More and more people are looking to invest in high risk assets like memcoins due to the instability in the world and high inflation across the board
We're seeing a shift where communities driven by profit are replacing those driven by blockchain and technology.
Major exchanges like Binance and Coinbase are listing more and more meme tokens, fueling a speculative frenzy. Meme token supercycle theory has no real fundamentals like memcoins itself. They attract traders with the promise of quick profits. There's no real utility or technology behind them. It's just people chasing the dream of becoming a millionaire with just $10. It reminds me of the ICO boom I was a part of. Even the most obvious scams raised money. They had fake profiles of team members, renamed social networks, made beautiful websites, and that was it. They just sold the standard tokens and out. Yes, there were some real projects, but only a few. Investors were just as fixated on quick profits as they are today. After the whole system crashed, most of them lost their money. Then they started thinking about technology and utility. It seems that the new generation of investors hasn’t learned from our mistakes and is falling into the same traps we did. Memcoins like Dogecoin, Pepe, and Shiba Inu will probably benefit from this hype around memes either way. On the other hand, most Meme 2.0 will experience a rug pool, not a supercycle:) Given the current market conditions, it's likely that the surviving 2.0 memtokens will see zero value due to their low liquidity and high FDV.

Meme Tokens 2.0 or ICO 2.0?

Unlocking the Future of DeFi: Renzo's and Chainlink Building the Future When it comes to the ever-changing world of decentralised finance (DeFi), innovation and security are the cornerstones that underpin the architecture of trust and efficiency. It is with great enthusiasm that we dig into the most recent and ground-breaking development in the DeFi environment, which is the integration of Chainlink Price Feeds by Renzo. Renzo, the restaking centre of Eigenlayer, has reached a critical milestone with this strategic move, which not only prepares the way for a new age of liquid restaking protocols but also represents a significant milestone for Renzo. This is why Renzo and Chainlink are ushering in a new era of decentralised finance today. A Leap Towards Secure and Intelligent Restaking The choice that Renzo made to use the capabilities of Chainlink Price Feeds on the Ethereum mainnet is the driving force behind this progress. This incorporation is not only a technical improvement; rather, it is a revolutionary step towards the provision of safe and intelligent liquid restaking procedures via the use of ezETH. As a result of having access to pricing feeds that are of a high quality and cannot be altered, Renzo is able to put itself at the forefront of DeFi innovation and establish new benchmarks for the industry. Why Chainlink? A Decision Rooted in Excellence The fact that Renzo has decided to choose Chainlink as its oracle solution is shown by the company's impressive track record and capabilities that are at the forefront of the industry. The pricing data standard that was established by Chainlink is an essential component of the Web3 ecosystem. It guarantees the safety of smart contract value that is worth tens of billions of dollars across the most well-known DeFi protocols. The fact that Chainlink is immune to attacks such as data manipulation, exchange failures, and flash crashes is illustrative of the high level of security and reliability that it brings to the table. The ezETH token that Renzo has created is a brilliant example of innovation since it enables you to obtain restaked ETH and LSTs in a simple and lightning-fast manner. Because of this connection with Chainlink Price Feeds, the utility of the token is increased. This is because it ensures that users get restaking advantages that are presented immediately in the price of ezETH, without the need to pay fees or wait. Potential Benefits and Possibilities Additionally, users of Renzo will benefit from a rewards system that is larger and more comprehensive. Providing awards in ETH, USDC, and Actively Validated Services currencies, in addition to ezPoints and EigenLayer points, demonstrates that Renzo is committed to providing its consumers with value that cannot be matched by any other platform.     As a consequence of this combination, Chainlink Price Feeds provide data of superior quality that originates from premium sources. Additionally, they are safeguarded by oracle nodes of the highest calibre that have been evaluated by specialists from the outside. The decentralised architecture of Chainlink provides protection against data tampering and outages, therefore ensuring that assets are priced fairly on the market and that they accurately reflect the economic worth of trade settings. A Glance Into the Future: The Prospects for the Partnership Between Renzo and Chainlink  As far as the immediate future is concerned, the possibility of Renzo and Chainlink working together once again seems to be favourable. In the future, there are plans to make use of more Chainlink capabilities, such as automation and interchange across chains. This paves the way for a great deal of freedom for development and inspiration. Insights from Renzo's Founding Contributor: A Vision That Is Shared One of the founders of Renzo, James, reflects on the path that has transpired since ETH Denver 2018, the event at which he first saw Chainlink. His admiration for Chainlink's development and the role it plays in translating smart contracts into practical applications in the real world is congruent with the goals that both organisations have set for themselves. This first merger is merely the beginning of a collaboration that will quicken the pace of innovation at DeFi while maintaining the highest possible standards of reliability and safety. Chainlink is one of the most essential components of decentralised computing since it enables a wide variety of domains to access and process data in the real world in a safe manner. The fact that it has a transaction value of more than nine trillion dollars makes it a distinctive addition to established applications and marketplaces with high integrity. Any anyone who is interested in gaining a deeper understanding of the capabilities of Chainlink should visit either chain.link or docs.chain.link and carefully go through the developer instructions that are provided. One indication that progress is being made in the decentralised finance field is Renzo's objective of making sophisticated Liquid Restaking strategies more accessible and simpler to implement. Through the use of institutional-grade node operators, Renzo makes it simpler to ensure the safety of AVS. Additionally, it provides you with a robust method to manage risks and monitor prizes.

Designing Fair and Efficient Blockchain Games: Conclusion and References

Oracles provide a secure and reliable way for smart contracts to access real-time market data, which is essential for various DeFi applications. API3 has developed an oracle node that is operated by the API Provider, removing the intermediary node layer, or middleman. This change in oracle architecture creates a scalable and transparent solution that enables first-party oracles to be aggregated according to user requirements. DeFi protocols looking to utilize first-party oracles do so by integrating dAPIs to their smart contracts. With developers in mind, dAPIs have been designed with a simple integration process that abstracts away the technical implementation of accessing data feeds. The API3 Market provides the ability to manage these data feeds while giving users access to a range of first-party data feeds. In the future, additional data feed services, such as capturing (OEV) will be accessible once a dAPI has been integrated. Oracle Extracted Value This tutorial will demonstrate how easy it is for developers to switch from Chainlink data feeds to API3’s first-party oracles. Choosing the Contract To demonstrate how easy it is to port over from Chainlink to API3, we are going to port over the DeFi options contract from this C . hainlink tutorial We don’t need to go over the entire contract because we will only be modifying a small section of the contract to port it over, but in summary, the contract enables users to create, buy, exercise, and cancel options within the contract using Ethereum (ETH) and Chainlink (LINK) tokens. It makes use of Chainlink’s aggregator interface for obtaining price feeds while exercising options. For more of an in-depth explanation, you can check out the . full guide Now let’s look at the code we want to modify: pragma solidity ^0.8.17;

} The contract initializes the AggregatorV3Interfaces via the constructor for both the Eth and Link datafeeds; these can later be used to fetch the price. The two functions and use the AggregatorV3Interface to fetch the price and return it. The struct defines how options are stored when they are created, along with the and array to store the created options. getEthPrice() getLinkPrice() options ethOpts linkOpts Porting it Over Porting over the contract to use API3’s dAPIs in this options contract can be done in 3 easy steps: Fetching the proxy address of the “ETH/USD” and “LINK/USD” dAPIs from the API3 Market Import the proxy interface from API3 repo and set the proxy addresses in the constructor Replace the and the logic with a function call to the proxy interface getEthPrice() getLinkPrice() .read() And that's it. You do not need to hold any special type of token to be able to read from the oracle, it is completely free to read. Over 100+ dAPIs are currently available on the api3 market and work on a self-funded basis i.e you can top up the gas wallets to start reading from the oracle. If the dAPI is already funded you just need to copy the proxy address as seen below: Here’s the same DeFi options contract updated to use API3 dAPIs pragma solidity ^0.8.17;

import "@api3/contracts/v0.8/interfaces/IProxy.sol";

contract Api3Options {
    //Pricefeed proxies
    address public ethProxy;

    uint ethPrice;
    uint linkPrice;
    //Precomputing hash of strings
    bytes32 ethHash = keccak256(abi.encodePacked("ETH"));
    bytes32 linkHash = keccak256(abi.encodePacked("LINK"));
    address payable contractAddr;
    
    //Options stored in arrays of structs
    struct option {
        uint strike; //Price in USD (18 decimal places) option allows buyer to purchase tokens at
        uint premium; //Fee in contract token that option writer charges
        uint expiry; //Unix timestamp of expiration time
        uint amount; //Amount of tokens the option contract is for
        bool exercised; //Has option been exercised
        bool canceled; //Has option been canceled
        uint id; //Unique ID of option, also array index
        uint latestCost; //Helper to show last updated cost to exercise
        address payable writer; //Issuer of option
        address payable buyer; //Buyer of option
    }
    option[] public ethOpts;
    option[] public linkOpts;

    //Kovan feeds: https://docs.chain.link/docs/reference-contracts
    constructor(address _ethProxy, address _linkProxy) public {
        //ETH/USD Proxy on Goerli
        ethProxy = _ethProxy
        //LINK/USD Proxy on Goerli
        linkProxy = _linkProxy
        contractAddr = payable(address(this));
    }

    //Returns the latest ETH price
    function getEthPrice() public view returns (uint) {
        (int224 value,uint32 timestamp) = IProxy(ethProxy).read();
        // if the data feed is being updated with a one day-heartbeat
        // interval, you may want to check for that.
        require(
            timestamp + 1 days > block.timestamp,
            "Timestamp older than one day"
        );
        //Price should never be negative thus cast int to unit is ok
        //Price is 18 decimal places
        return uint(uint224(value));
    }
    
    //Returns the latest LINK price
    function getLinkPrice() public view returns (uint) {
        (int224 value,uint32 timestamp) = IProxy(linkProxy).read();
        // if the data feed is being updated with a one day-heartbeat
        // interval, you may want to check for that.
        require(
            timestamp + 1 days > block.timestamp,
            "Timestamp older than one day"
        );
        //Price should never be negative thus cast int to unit is ok
        //Price is 18 decimal places
        return uint(uint224(value));
    }
    
    //Updates prices to latest
    function updatePrices() internal {
        ethPrice = getEthPrice();
        linkPrice = getLinkPrice();
    }
    
    -----------------------
    -----------------------
    
    
} As you can see, we only needed to call on the interface to start reading from the datafeed. We ended up with lesser lines of code and a much simpler reading interface. You can try running the contract yourself on . (Note: The remix version only allows you to open and close options in ETH for simplicity). .read() IProxy(ethProxy) REMIX Why use dAPIs ? dAPIs have been designed to abstract away the technical implementation of data feeds. Once a dAPI has been imported to oracle contracts, the API3 DAO can redirect the dAPI mapping upon user requests. This means that data feeds can be upgraded from self-funded to managed dAPIs, or directed to read alternate reference data with zero technical implementation. Any update to data feeds, or a lack thereof, can create opportunities for OEV, such as arbitrage and liquidations. During each of these interactions value is leaking from the dApp users to both searchers and validators. Once a dAPI has been integrated, DeFi protocols will be able to capture Oracle Extractable Value without any further technical implementation. Additionally, switching from Chainlink to API3 data feeds means no major alterations to smart contracts. This mitigates the need for audits while keeping battle-tested code intact.
