Common Computer participated in Ethereum Denver 2022 to promote AI Network and introduce AINFT and AIDAO. As we advocates open-resources, we would like to analyze the teams in the Hackathon Top 30 and share them with more developers. Part 1 analyzes Top 21 to Top 30.

Top 30:22222. World-VIP Membership Through NFT Ownership

22222.World provides a ticket management and verification system based on tableland, a blockchain database management system. It can be applied when purchasing tickets. In most cases, existing ticket management verification systems are centralized. As a result, there is a problem that it is vulnerable to security and costs a lot of money to operate. Recently, many companies have used tickets in conjunction with NFT, and they have focused on the fact that there is currently no NFT ticket management platform in the Web3 market. Customers can link their NFT tickets to 22222.world to manage ticket usage, usage time, and validity.

Top 29: Colorado Aware-Moving Colorado To A Net Zero World One Notification At A Time

It is a project to solve eco-friendly renewable energy power management through blockchain. It is said that the U.S. state of Colorado, which is focusing on eco-friendly renewable energy generation, does not have a system to efficiently manage it. The grid, a unit of renewable energy production, is distributed and arranged in each region, making it the best item to manage with a blockchain. The system performs power generation and consumption management of the grid in a blockchain and even alerts you in case of an emergency.

Top 28: farm kudos-Rewards and Incentives for Farmers and Food System Supporters

It is a virtual local currency reward system created to encourage Colorado’s agricultural food system.

When farmers and consumers create a group ‘Guild’, Farm kudos’ DAO grants guild the right to issue ‘Kudo’ tokens. If their farmers reach environmental goals, such as producing eco-friendly crops, or if consumers contribute to revitalizing the local economy, such as purchasing food made by Colorado, the guild will issue a Kudo to compensate. Users can receive discounts, special events, and benefits such as joining the household cooperative through Kudo. The more the guild helps the local agricultural economy, the more Kudo issuance increases, so farmers and consumers in the group contribute to greater compensation.

Top 27: Background Network: Discord Chatbot & Help Center Protocol- Decentralized Help Center as a service protocol

It is a service for the management of QnA channels, which are widely used on the web. It is a chatbot using GPT-3 and a web page like Reddit that collects and shows it. It is a project that focuses on the limitations of existing discord used in CS. In the case of the discord, it is difficult to find questions easily because it is in the feed format, and duplication occurs frequently in the content. In addition, phishing fraud can occur because they are vulnerable to external attacks.
This service uses your wallet in a form similar to Stack Overflow to join the community and ask or answer questions. Tokens are paid in return for this and encourage users to share quality information. Discord bot automatically connects to related questions and answers by looking at Q&A.

Similar Web2 service: Stack Overflow

In Stack Overflow, if you open your ID through your wallet as above, you can freely post questions or answer them.

Similar Web3 service: Quiz Talk

QuizTalk is a knowledge-sharing platform that allows you to solve or take quizzes, and participants freely produce and participate in content to receive tokens as rewards. The more active participants participate, the greater the reward, and there is a self-verification system that can filter out incorrect answers and overlapping problems.

Top26: Intuition-Game-Theoretic Decentralized Identity System

As one of the utilization of the blockchain, it is a decentralized ID (DID) service that is still actively discussed. It means a system in which an individual has control of his or her information, not controlled by a central system when identifying someone. Representative services currently in operation include Raon Secure’s OmniOne using the EOS platform and Coinplug’s MYKEEPiN.

Problem 1 — Modern society is complicated. Because it interacts with numerous people and many objects, the degree of exchange is bound to be weak once it is exchanged. Intention solves this problem by strengthening ID metadata, which helps us better understand what’s around us.
Problem 2 — Modern society adopts a one-on-one comparison with information on DB to verify IDs. However, other personal information that does not exist in the DB may not be properly reflected. Therefore, forming ID metadata can comprehensively reflect personal information.

Similar Web2 service: SNS and recommendation algorithms have a similar structure. These include algorithms for recommending friends based on personal information entered on Facebook or advertising recommendation algorithms based on information collected by Google through various channels. Since existing services are based on input information, there is a limit to the comprehensive judgment of personal information (if the recommendation algorithm is wrong).

Top 25: Do or DAOn’t?-Find a DAO that fits your needs

It helps new DAO participants evaluate the level of transparency and decentralization of DAO. Users can select DAO that meets their criteria through Trust score. Trust score is rated as five metrics: Governance, Treasure, Token Distribution, Social Media, and Ratings. Trust score can be customized and weight which part you will focus on.

Similar Web2 service: Credit rating agencies in the financial industry can be cited as similar examples. It mainly plays a role in evaluating whether the target institution can repay it after financing. It is in line with the fact that it comprehensively evaluates companies (targets) using various information such as corporate information and market conditions.

Similar Web3 service: It’s a new tool. A similar example is CoinMarketCap, which provides overall information about crypto. Coin Market Cap is a service that provides comprehensive information such as SNS activity, coin market capitalization, and trading volume. This service can be seen as a pioneering new industry in that it goes beyond providing simple information and focuses on DAO.

Top 24: AcademyONE- An education platform allowing projects to outsource and incentivize creation of high quality learning materials. A platform for educators to make money fulfilling bounties. A place to learn and earn governance rights in the process.

Open education platforms or outsourcing platforms usually have a fixed service unit price. That’s why it was hard to motivate educators. AcademyONE takes a strategy to boost educators’ morale by introducing a reward system. Users with common learning goals create a group and invite educators to achieve their goals. Educators create learning media and receive rewards after providing them to users. At this time, the reward is paid differently depending on the degree of completion, so educators are motivated to give high-quality classes.

Top 23: Skew You (Automated Skew Farming)-Defi Vault to automate skew farming with risk mitigation for perpetual pool

Perpetual pool is a new concept in which anyone can take a short or long position on underlying assets. Permanent pools are serviced in many places, so it’s important which permanent pool you take a position in. ‘SKew you’ will automatically allocate funds to the most profitable skew arbitrage position. This is done fully automated by smart contracts. With the help of automation contracts, users can deposit funds into a vault that will automatically allocate their funds to highest earning skew arbitrage positions.

Top 22: DustSweeper-Clean small token balances from your wallet and swap for ETH!

source: Dustsweeper

DustSweeper allows users to swap small balance tokens (dust) for ETH without expensive gas transactions. Users just have to approve the tokens they’d like to sell, and ‘market taker’ bots execute the swap.

Many Ethereum mainnet users have low-balance tokens (<$500) in their wallets from old trades, airdrops, and trying out apps back when gas was cheap. They’d like to sell these tokens for ETH to clean out these wallets but gas prices are prohibitively high for swapping on Uniswap/Sushi/etc.

Top 21: SlowSwap- AMM with a Verifiable Delay Function (VDF) that prevents MEV front-running and sandwiching issues

SlowSwap is an AMM with a Verifiable Delay Function (VDF) that prevents MEV front-running and sandwiching issues. This project was implemented during the EthDenver 2022 Hackathon.

It’s a kind of AMM Defi service. It is a service to overcome the shortcomings of the decentralized exchange(DEX), which has emerged differently from the existing central exchange.

Existing central exchanges manage order information at once by the central server, so the speed is very fast and accurate. In the case of the decentralized exchange (DEX), it is traded on a blockchain, and traders who pay a lot of fees will have priority. During transaction, another trader or bot comes in the middle and pays a higher price than expected and the transaction proceeds. This is called the sandwich phenomenon or deadlock phenomenon. At this time, the problem of bot coming in earlier and interfering with the transaction is called the front-running problem.

To solve this problem, Slowswap chose the VDF proof method. VDF is short for Verifiable Delay Function, which serves to verify whether this function is an appropriate function with input and output.

Similar Web2 service: In the stock market, there is a market maker to reduce the difference in trading prices (the price difference between buying and selling prices) and to supply market liquidity.

Similar Web3 service: Decentralized exchanges (DEXs) such as Uniswap and Kyber Network use Automated Market Maker to implement DeFi.
