We introduce a new approach to block building called parallel block building. Instead of treating all transactions as potentially conflicting - as traditional sequential building algorithms do - parallel block building recognizes that most transactions in…

A blazingly fast, modular and contributor friendly Solidity compiler, written in Rust

最近因緣際會下看到 ERC-6551 提到 Nick’s Factory，好奇地去了解一下這是什麼魔法，發現了古老（？）而有趣的 Nick’s Method。這是一個可以在無信任的條件下，在特定地址上執行特定交易的方法（即便你和所有人都不知道密鑰）。在這篇文章中，我想介紹…

Demystifying Arbitrageurs’ profits, LVR, and sandwich attacks: batch trading as an AMM design response

Introduction We are pleased to announce that after working for months with the StarkWare team, we are finally launching the Stone CLI, a tool for easily proving and verifying Cairo programs! Huge thanks to the StarkWare team for their work and guidance as…

Recently Eric Voskuil shared a benchmark of doing IBD with Libbitcoin versus Bitcoin Core, showing that Libbitcoin could perform IBD 15x faster than Core with -assumevalid. Libbitcoin’s approach is very different from Bitcoin Core. This writeup intends to…

In January, we identified and reported a vulnerability in the Lotus and Venus clients of the Filecoin network that allowed an attacker to remotely crash a node and trigger a denial of service. This issue is caused by an incorrect validation of an index, resulting…

Many DeFi Protocols have decentralised using DAOs and token governance. This article explores the common vulnerabilities in the...

How Chainflip is bringing BTC liquidity on-chain

DeMystifying MEV in Sui

AI-enabled code assistants (like GitHub’s Copilot, Continue.dev, and Tabby) are making software development faster and more productive. Unfortunately, these tools are often bad at Solidity. So we decided to improve them! To make it easier to write, edit,…

Programmable cryptography enables fun, safe, and intelligent experiences.
Hardware is necessary to achieve programmable cryptography at scale.
How to think about the levels of secure hardware?
Let’s get to Level 5.

This book aims to explain, from the ground up, how peerDAS actually works.
It covers all the aspects of peerDAS (or more especially, how does peerDAS is implemented inside the Prysm Ethereum consensus clients), without going too deep into the exploration.…

How do different devices stack up for signing multisig transactions? See the results of Jameson Lopp's tests.

Prove you know without telling me the whole thing.

The article introduces a structured testing framework to help developers write more thoughtful, effective tests aimed at catching severe bugs in their protocols.
