Grantee Roundup: July 2021 | Ethereum Foundation Blog

It is always interesting to hear that new grants are awarded, but what happens after the announcement? In this series, we will check several projects that are in progress-or are already on the finish line. Read on to learn about some recent milestones and achievements of the grantees!

Mutual visits

For users who switch to the new social media platform, one of the biggest friction points is rebuilding their reputation. InterRep aims to reduce this friction by allowing users to associate social media accounts with an Ethereum address, which can be used to confirm their identity on the new platform.

Recipient Jay Graber and Raphael Roulette Implemented UI and Smart contract for InterRep MVP (You need to connect to MetaMask on Ropsten to interact with the UI). The initial version was released to Ropsten on June 30, allowing the verification of Twitter accounts via API and private linking to Ethereum addresses. The NFT “badge” is cast to the link address as a proof of ownership of the relevant reputation.See Launch pad More detailed information on how InterRep works, use cases, and future plans.

Status box, Philip Zane and Jules Hedges Used to combine game engines

game theoryStudying the strategic interaction between rational participants is the core of the mechanism design of a decentralized system. However, the “games” involved in real-world interactions, such as verifying the blockchain or voting in DAOs, are extremely complex and difficult to reason about.

Enter Combinatorial game theory, It treats large, complex games as a combination of smaller, simpler games. The equilibrium of a complex game (that is, any given participant has no incentive to change their strategy, as long as the strategies of all other participants remain the same) can be defined based on its simpler components.

Although these concepts are highly related to Ethereum, the basic theory is extremely complex. Philipp Zahn and Jules Hedges aim to make the theory easier to understand by creating a software engine to model and analyze strategic interactions through modular programming.recent Post a post To share more detailed information about the system, the system uses a small domain specific language and Haskell to define functions, and uses the auction format as an example to illustrate the process.

This introduction is just the beginning-the project is at an early stage and will continue to evolve and add new features. Follow @Statebox Get updates and go to the project’s GitHub Keep up with progress or contribute.

Blog blog blog!

The Ethereum Foundation Privacy and Expansion Team has published a blog where they will share what they have discovered and developed, usually in close collaboration with the grantees, as well as guest posts by the grantees themselves.

Inaugural guest post, Introduction to Optimism’s Optimistic RollupFrom Kyle Chabone, Who received a grant to assess the security attributes Optimism Optimistic summary is achieved. This is not an audit, but an opportunity to gain a deeper understanding of the structure that is expected to be heavily used and imitated. The results of the evaluation will be announced soon; at the same time, Kyle’s post provides an overview of the agreement, putting it all in context!

Some other recent posts by the grantee:
