Talks Digest

Day1 in ETHCC full of energy. Though the temperature is high in Paris, the enthusiasm for information exchange is even higher. We attended talks we thought would be interesting, and compiled the information for our community. Even if you weren’t able to attend Eth Paris, it will feel like you’re here with us! Let us go through some interesting talks we attended.

The Soul of a New Machine: Next-Generation Optimistic Rollups with Cannon

📹 Video

Shared by Nicolas Laurent from Optimism. Optimism is a layer 2 Optimistic Rollups network designed to utilize the strong securities of Ethereum while reducing its cost and latency. Fault proof is a critical part for OP rollups to be workable in practice. Even with the assumption that only one verifier needs to be honest, the verifying process is still a huge amount of work to make it happen on L1. Optimism introduces Cannon, which is a challenge game system composed by Minigeth and Preimage oracle. These aim to make proving L2 blocks on L1 to be more efficient. Minigeth splits the execution of transactions into steps by emulating a MIPS machine. With the state information provided through Preimage oracle, the challenge can be processed with less resources.

Learning My Way into Web3 Community Building

📹 Video

Shared by Reka.eth, the founder of Guild.xyz. Guild.xyz is the solution she founded to build a web3 community. Which is to simplify the new user onboarding journey. For example, by following an account on Twitter, you will get a new role when you join its discord. With the role, you will only see 3 channels (introduction, general, education). In the education channel, you will find a link to a google document with more education documents. When you complete the reading, you will get access to more discord channels, where you can get a link to github to contribute if you are a developer.

OpenZeppelin Contract: Past and Future Roadmap

📹 Video

Shared by Hadrien Croubois from OpenZeppelin. Openzeppelin provides security products to build, automate, and operate decentralized products. Openzeppelin introduced their work in three main parts: Contracts, Audit and Defender. Contracts is the library that we are most familiar with. The current version includes several key features such as Token, Governor, Timelocks, CrossChainEnabled, etc. Except for Solidity, Openzeppelin also introduced their library of Cairo. Another major product, Defender, is the interface that enables users to construct and manage their contract in a more friendly way. This includes all the modularized functions supported by their contract library. For the upcoming features, we can look forward to more functions in the library, including more functions related to upgradability (like Diamond), staking, cross-chain message sending, and features like batching transaction and tx simulation in defender.

Towards a NFT Rental Standard

Shared by Jerome de Tychey from Cometh. Cometh is a blockchain game that lets users own yield-generating NFTs. Blockchain gaming is being increasingly discussed and rising in popularity. Cometh aims to build a game engine that supports all kinds of common features. Some of these features include asset usage (such as NFT crafting), in-game nft rentals, dex as a service, a market place, etc. Cometh proposed a NFT rental system that is compatible with ERC721. By utilizing two NFTs (borrowed/lent), which is similar to the idea of aToken and debtToken, to manage the relation between the borrower and lender. Looking forward to more features that describe the games that are implemented through the same engine to be more interactive with each other.

DAO Vulnerabilities & Resilience

📹 Video

Shared by Kelsie Nabben from BlockScience. BlockScience is an engineering, R&D, and analytics firm specializing in complex systems. Kelsie shares a very thorough understanding about how to evaluate the risk of the DAO. Using the term resilience represents the recovery ability, which should make a DAO more sustainable. Vulnerabilities can also produce opportunities that lead to adaptation, resilience, and growth.

Designing a Blockchain Ecosystem for Web2 Games

📹 Video

Shared by Sam Seo from Klaytn. Klaytn is a open source public blockchain that provides performance and scalability for anyone that wants to build on top of it, with a focus on gaming projects. There are 3 key components for those Play-to-earn(P2E) projects: open governance, open economy and on-chain ownership. On the other hand, there are also some problems they are facing such as: high barriers to entry, game distribution channels being dominated by web2, ecosystem disturbance by game bots, regulatory risk, and the worst part, creating games that are not interesting at all.

However, for those Web2 games, the user base is still the most important factor that attracts them to get in the world of Web3, which means that supporting more chains is also important. Other features like owning their own blockchain game platform, low tx fee, high performance, stable, faster development, lower latency are also critical parts to maintain the original UX. Those Web2 companies have tremendously large resources and strong IP and development experience, which can definitely bring something different to Web3 gaming. Klaytn introduced a solution for those web2 game companies which is an easy way to build their own blockchain game ecosystem. This Includes their own chain, dex, bridge, NFT marketplace, etc. They are seeking to become the one to push the gaming industry to the next generation.

Security Monitoring for On-chain Attacks

📹 Video

Shared by Christian Seifert from Forta Protocol. Forta protocol is a decentralized monitoring network that aims to protect all assets on web3. Their pitch is that prevention is important but not enough, and early detection and mitigating the situation is necessary. The attack can happen through several stages: funding, preparation, exploit, money laundering. By understanding the protocol and situation, including decomposing the protocols, identifying the risk, and identifying the monitoring requirements, the exploit can be eased — even prevented. Forta also supports custom bots to be built and alerts the protocol ahead of time to attempt to prevent any exploitation.

Auction, Coins and Security

📹 Video

Shared by Gonçalo Sá from Consensys Diligence. Consensys Diligence provides a full scope project incubation, marketing, and blockchain app design and development. Today they announced that their audit reservation auction is now online. A new token TURN is introduced to purchase through dutch auction, which can be used to make a reservation for future audit.

The Next Advancement in Cross-Chain UX

📹 Video

Shared by Jaz Gulati from Catalog. Catalog is a dex that is built on the Ren blockchain. By applying the features provided by the Ren project, and the routing result provided by 1inch, Catalog is able to utilize the liquidity provided on different chains. This results in a seamless user experience. This includes a single Catalog account that can be triggered through signing metadata by all the evm-based wallets.
