Summary of beneficiaries: May 2021 | Ethereum Foundation Blog

[ad_1]

It’s always fun to hear about new grants as they are awarded, but what happens after the announcement? In this series, we’re going to check out a few projects that are well advanced – or already at the finish line. Read on to learn more about some recent milestones and achievements of beneficiaries!

RSG

GSN (Gas Station Network) provides a decentralized infrastructure to dapp builders to reduce friction in their UX while ignoring transaction costs. A relay network makes “collect calls” to payer contracts which can implement any logic of gas payment conditions. A dapp developer could choose to cover the cost of gasoline themselves, allow users to pay for gasoline with a non-ETH credit card or token, or allow ETH-free withdrawals from addresses. stealthy. GSN v1 has been put online since 2019, but the recent version v2 added a host of new features and improvements, including:

  • New modular sectional architecture give developers more choice in which parts of the system they need to understand or trust for their specific use case
  • A more decentralized and censorship-resistant security model
  • Wallet UX improvements to make transaction signing more transparent and secure
  • Customizable gas grief reliefs

Quadratic dollar home page

The quadratic dollar homepage is inspired by the Million dollars of hospitality, which sold display space by the pixel. Rather than simply selling space, the Quadratic dollar home page (QDH) allows users to determine the relative scale of images on the page using two experimental blockchain voting mechanisms:

  • Quadratic vote allows voters to indicate not only their preferences among a set of options, but the strength of those preferences. On QDH, holders of MOON, BRICK or POAP tokens can vote as many votes as they have tokens, divided between the images on the page as they see fit.
  • Minimum anti-collusion infrastructure (MACI) discourages corruption by making it impossible to verify a user’s vote. QDH achieves this by giving the user an “I am corrupted” option when signing the voting transaction. This causes the transaction to be sent with an incorrect nonce, invalidating the vote. The user can then change their signing key to submit a second valid vote.

Recipient Raman Shalupau recently completed his funded work on QDH user interface, MACI smart contracts and documentation. For a more in-depth look at how QDH works, this demo a provides a video overview of the web interface and major components. You can find Raman Shalupau on Twitter @ksaitor, or contribute to the Quadratic Dollar homepage on Github.
