Sherlock AI reported a Critical vulnerability in the @40acresFinance protocol. The 40acres team generously allowed us to share the details publicly so others can learn from the finding. Here’s how the vulnerability worked: First, veNFTs are a special type of vote-escrowed…
The Solidity function dispatcher is a tree where: - Internal nodes perform binary splits. - Leaf nodes contain up to 4 function selectors, tested linearly. Protip 1: the `fallback` function's bytecode is generated twice in the bytecode. To reduce bytecode size, wrap the…
Presenting 'The Road to Core Solidity', a series of blog posts through which we will share where we are headed with the language. Let's take a look at the overview!
We paused Parallel EVM last October for this exact reason — 2x throughput in exchange for complex node integration with forks. There were many lower-hanging fruits for a 2x. Nevertheless, after another year of tackling the hardest performance problems, we’re bringing Parallel…
I wrote about it on my account a lot since I was doing EVM performance tuning and actual parallel execution for our MEV searcher on BSC back in 2021-2022. The short answer is that in the real world scenarios, most txs use contentious state and cannot be parallelized, so you're…
What prevents an attacker or competitor from deploying the same contract but with the GAS2ETH calls removed (so users get the same functionality but no fee is paid)?
guys, we need your feedback. The `GAS2ETH` opcode (the EIP is written by @big_tech_sux and myself) is proposed for inclusion for Glamsterdam and we need further feedback about potential ambiguities in the specs, security issues, or any other concerns. The tldr for the EIP is that…
Progress toward real-time proving for Ethereum L1 is nothing short of extraordinary. In May, SP1 Hypercube proved 94% of L1 blocks in under 12 seconds using 160 RTX 4090s. Five months later Pico Prism proves 99.9% of the same blocks in under 12 seconds, with just 64 RTX 5090s.…
Announcing Pico Prism, the state-of-the-art zkVM for Ethereum real-time proving. 99.6% of blocks proven under 12 seconds, 6.9s average with 64 RTX 5090 GPUs. This marks a major step toward scaling Ethereum by 100x and a future where you can validate the chain from a phone.

Sherlock AI discovered a Critical vulnerability affecting $2,400,000 in a live lending protocol. This is the first known instance of an AI uncovering a multi-million-dollar bug on mainnet. Here's how Sherlock AI surfaced the vulnerability:
Fusaka is coming and it is bringing more blobs! Testnet upgrades (Holesky, Sepolia, Hoodi) have been scheduled for October of this year. If you are running nodes or infra, please refer to the blog post in next tweet for further details.
Introducing Ethereum Debugger (EDB) EDB is a smart contract debugger created by @troublor and @i2huer, and open-sourced to contribute to the EVM ecosystem. Enabling: → Source-level stepping → Local/state variable inspection → Solidity expression eval at any step

Fusaka will fix this. But also, safety first is of the utmost importance for Fusaka. The core feature, PeerDAS, is trying to do something pretty unprecedented: have a live blockchain that does not require any single node to download the full data. The way PeerDAS works is that…
