What L2s need from Based Rollups

Some unstructured thoughts on what Ethereum needs to focus on to accelerate the L2 roadmap

On Token Vesting

Token vesting in Web3 controls token release to prevent mass sell-offs, protecting price stability. Learn what it is, how it works, and why strategies like randomized vesting could improve market health and protocol governance.

(Yet another) Circle STARK tutorial

Dive into the intricacies of Circle STARKs, their efficiency over Mersenne 31 prime, and the challenges of FFT/FRI compatibility.

Understanding GKR

Cryptographic commitments often bottleneck SNARKs. Circle STARKs and Binius reduce costs but add new challenges. GKR offers another path, cutting overhead by almost avoiding commitments entirely.

Investigating a Zcash Web Wallet

ChainSafe R&D has been investigating the feasibility of a Zcash web wallet. Such a wallet would allow easy onboarding to Zcash. It is also the first step in building a browser extension wallet or a MetaMask snap.

Forks Aren't Always Safe

Forking open-source smart contracts is risky. Developers often inherit existing bugs or create new ones through modifications, leading to major exploits like those seen with Grim Finance and Meter. Transparency, collaboration, and auditing new logic are crucial to prevent costly vulnerabilities.

Improving Web3 UX: Deferred Transaction Inclusion

Waiting for transaction inclusion doesn't have to mean, halt and wait. Let's set the stage a bit... I'm a liquidity provider (LP) for a DeFi protocol and receive LP tokens. I can stake those LP tokens and receive bonus rewards ("farming"), which is highly appealing and a common practice in

Onchain Dispute Games: Past, Present and Future

Blockchains use dispute games to efficiently verify computations. Instead of costly on-chain execution, a statement is accepted unless challenged. Protocols like one-step fraud proofs and bisection games resolve disputes, saving resources by only performing full verification when necessary.

Transaction fee mechanism design

For a sustainable decentralized ecosystem, it is essential to align incentives. This prevents the system from favouring one actor too much.

Security for the paranoid

People are prone to making mistakes, but rarely do they make a royal one. When it comes to protecting your digital assets, however much, there is nothing more important.

Intro to social choice theorems

Before designing governance for DAOs, understand that onchain voting is a useful tool. However, it does not fix the main problems in social choice theory.

Building a Polywrap SDK Wrapper for Substrate and Polkadot

Authored by Colin Adams Last year, ChainSafe received a co-sponsored grant from Polywrap and the Web3 Foundation to develop a Substrate "wrapper." That is, a universal SDK powered by Polywrap's technology that aims to significantly improve the experience of building on Polkadot and Substrate. Background Polywrap is the technology behind
