On the evening of April 25th, Gitcoin launched a new round of donations "Gitcoin Grants Beta Round". This round of donations will last until May 9th, and plans to use the second matching mechanism for all core rounds (Core Rounds) The program provided $1.25 million in matching funding.

Gitcoin’s Beta round of donations covers a total of five core rounds, all of which are voted by the community, including "Web3 Open Source Software", "ZK Technology", "Web3 Community and Education", "Climate Solutions" ", "Ethereum infrastructure" and other five categories.

In addition, this Beta round donation also provides a number of Featured Rounds such as "Web3 Social" and "Witch Review". These rounds cover partner projects that are consistent with Gitcoin's vision, but the matching The magnitude of funding is much smaller than that of core rounds. It is worth mentioning that in the special round, there is a "Greater China" specially designed for Chinese projects, which contains a batch of Chinese background projects.

Core Round: Web3 Open Source Software

• Project 1: Flexible Voting

Official Twitter: https://twitter.com/ScopeLift

Flexible Voting is an extended application of the Governor system that has been widely used in various DAOs. It allows arbitrary delegated voting contracts to aggregate votes from multiple token holders, which provides support for various DAO voting-related The new use case provides a permissionless interface.

Flexible Voting listed some potential use cases of the project. For example, users holding governance tokens can use the entrusted voting contract to retain governance rights while participating in DeFi interest generation. Another example is that users can use BridgeStreet tokens to directly vote on governance at Layer 1 (There is no need to migrate back to the main network), another example is privacy voting and so on.

• Project 2: ENS Wayback Machine

Official push:https://twitter.com/blossom_labs

ENS Wayback Machine can visualize historical IPFS content related to ENS domain names and support user access, thus helping researchers explore the evolution of decentralized networks.

With the development of the decentralized network, the need to access and track historical content related to ENS domain names began to amplify. Traditional archiving tools (such as Internet Archive's Wayback Machine) are not specially designed for ENS and IPFS content, which makes the archiving of decentralized content operational obstacles, and the emergence of ENS Wayback Machine fills this gap well. vacancy.

• Project 3: Uniswap V3 Calculator & Simulator

Official push:https://twitter.com/iakshatmittal

Uniswap V3 Calculator & Simulator literally translates to Uniswap v3 calculator and simulator. This is a data analysis platform based on Uniswap V3, which provides position statistics, historical fees, transaction volume, price, APR and other common data.

Core round: ZK technology

• Project 1: Proof of Innocence

Official push:https://twitter.com/chainway_xyz

Proof of Innocence is one of my personal favorites from this round of giving.

Proof of Innocence is an upper layer application of Tornado Cash. Tornado Cash, as the most mainstream currency mixing protocol on Ethereum, allows users to conduct private transactions while disrupting the on-chain connection between the sending address and the receiving address. However, in some cases, users may wish to demonstrate that their use of Tornado Cash is above board and not related to any illegal activity.

This is where Proof of Innocence comes in, a tool that allows users to prove that the funds they withdraw from Tornado Cash are not from known malicious addresses, allowing users to prove their innocence without revealing their identities.

• Project 2: Sprint checkout

Official push:https://twitter.com/sprintcheckout

Sprintcheckout is a zkEVM-focused Web3 payment Dapp, which currently supports zkSync Era, Polygon zkEVM, and Scroll testnets.

The function of Sprintcheckout can be understood as an e-commerce payment gateway, through which merchants can accept ERC 20 payments after integrating the API.

Core Round: Web3 Community and Education

• Project 1: ETH Daily
  

Official Twitter: https://twitter.com/ethdaily

ETH Daily is a daily podcast covering the latest developments in Ethereum.

Core Round: Climate Solutions

• Project 1: Litter Token

Official push:https://twitter.com/litter_token

Litter Token is simply a "garbage to Earn" project. Users pick up trash and upload proofs in discord, and the community will pay you LTK tokens (can be cashed out!).

Core round: Ethereum infrastructure

• Project 1: Stereum

Official Twitter: https://twitter.com/stereumdev

Stereum is an Ethereum node installation, setup and management tool.

Setting up an Ethereum node is technically demanding and requires a lot of research and preparation. Faced with this challenge, many people have chosen to use various staking services. This choice is understandable, but it inevitably exacerbates the centralization of Ethereum.

Stereum hopes to remove barriers for users who are willing to run an Ethereum node but lack the relevant knowledge. Stereum It provides an intuitive GUI that simplifies the node installation process with just a few clicks, thereby reducing the barrier to entry and complexity. Stereum hopes to attract more users to deploy nodes and promote the decentralization of Ethereum.

• Project 2: Kakarot

Official Twitter: https://twitter.com/KakarotZkEvm

Users who are familiar with StarkNet must be familiar with the project.

Kakarot is a ZK EVM written based on the Cairo language. It is not a network itself, but a set of smart contracts, which can be understood as an interpreter of EVM bytecode. Kakarot can be deployed on StarkNet and supports all 142 EVM bytecodes, so Kakarot can be used to run Ethereum smart contracts on StarkNet.

(In anticipation of the StarkNet airdrop, Kakarot might be the most worthy project?)

• Project 3: Ephemery Testnet

Official push:https://twitter.com/ephemerytestnet

Ephemery is a self-resetting testnet where each network iteration is created by a specific function that deterministically generates a new genesis state.

Featured round: Greater China

In addition to the above-mentioned core round projects, you can also support some Chinese-background projects in the "Greater China" round, such as the full-chain analysis tool Chaineye, Web3 mailbox MetaMail, Web3 open source academy WTF Academy, etc.

How to donate?

First, before donating, you need to checkGitcoin Passport, an on-chain identity credential that is scored based on the historical activity of the address, in order to prevent the increasing prevalence of Sybil attacks.

The status of Gitcoin Passport will be reset every 90 days. Only when the status is in the latest version and the score exceeds 15 will the secondary matching mechanism be triggered-in simple terms, if you donate a sum of money, Gitcoin will also donate a sum simultaneously. (You can donate without reaching the score, but you can't trigger a match.)

Next, we can make donations. By clicking the "shopping cart" icon at the bottom right of each specific item in each round, it can be added to the ranks of "to be donated". It is worth noting that the items added to the "shopping cart" in different rounds will not be displayed together, so if you want to donate to the five core rounds, you need to click on different rounds in order to donate.

Next, it’s time to make money. We can choose to donate in DAI or ETH, and the amount can be completely customized. After confirming the specific amount, click Submit your donation on the right to submit the transaction. I personally recommend that you choose ETH for donation, because using DAI will have an additional authorization transaction, which requires more gas fees.

After the transaction is confirmed, the Gitcoin interface will jump, and a word of thanks pops up.

According to this operation, repeat the operation several times in other rounds.

It is worth mentioning that this Gitcoin donation only supports the Ethereum mainnet, so the gas cost is relatively high. It is recommended that you decide whether to operate according to the actual situation.
