Beneficiary Recruitment: May 2021 | Ethereum Foundation Blog

It’s always nice to hear about new grants being awarded. But what happens after the announcement? In this series, we’ll take a look at a few projects that are either well underway or have already reached the finish line. Read on to learn about our grantees’ recent milestones and achievements!

GSN

Gas Station Network (GSN) provides a decentralized infrastructure for dapp builders to reduce friction in UX by abstracting transaction costs. The relay network makes a “collect call” to the paymaster contract, which can implement the logic for the gas payment terms. dapp developers can choose to cover gas costs directly, allow users to pay for gas with a credit card or token other than ETH, or allow withdrawals without ETH from a stealth address. GSN v1 is released From 2019But recently v2 release Many new features and improvements have been added, including:

• New modular composable architecture Giving developers more choice about which parts of the system they need to understand or trust for specific use cases.
• A more distributed and censorship-resistant security model
• Wallet UX improvements to make transaction signing more transparent and secure
• Customizable gas gripping relief

Quadratic Dollar Home Page

The Quadratic Dollar homepage is Million Dollar Homepage, selling display space by the pixel. Rather than simply selling space, Quadratic Dollar Home Page (QDH) allows users to determine the relative scale of images on a page using two experimental blockchain voting mechanisms.

• secondary voting Voters can indicate not only their preference among a set of options, but also the strength of that preference. In QDH, holders of MOON, BRICK or POAP tokens can vote in any way they choose, as many tokens are distributed among the images on the page.
• Minimal Collusion Prevention Infrastructure (MACI) Prevents bribery by preventing users from seeing how they voted. QDH achieves this by providing users with an “I was bribed” option when signing a voting transaction. This causes the transaction to be sent to the wrong nonce, invalidating the vote. The user can then change the signing key to submit a second valid vote.

Grantee Raman Shalupau recently completed funded work on the QDH user interface, MACI smart contracts and documentation. For a more detailed look at how QDH works, see: demo a provides video guidance for both the web interface and backend components.
