Protocols take time to mature, predicts 2024 at the earliest for a secure decentralized rollup

There seems to be a great underestimation on how long new crypto protocols take to mature. E.g. I don't expect any smart contract rollup to be battle-tested, secure & decentralized till at least 2024, and the zkEVM stuff - not till 2025 at the earliest.Sure, they will be usable much before then (already are now), and it's possible Arbitrum gets to a pretty good state in 2023 - enough to shed the beta tag - but will I put any sizeable portion of my wealth on it? No, not till it's battle-tested and nearly as secure as Ethereum L1

Targeting Shanghai upgrade, network bandwidth testing will determine target blob sizes

EIP4844 will drive 10-100x fee reductions and higher transaction throughput for layer 2 rollups. It does this by introducing data availability to Ethereum in the form of "blobspace", which is purpose built for rollups. This change is critical for driving adoption of Ethereum - for example at Coinbase, “we see EIP-4844 as a key enabler for bringing our customers into the cryptoeconomy with a secure, easy to use experience that is faster and cheaper”.

Project Update

Fast G2 subgroup check in BN254

BLS12-381 is now universally recognized as the pairing curve to be used given our present knowledge. As probably know though BN254 4 is currently the only curve with precompiled contracts on Ethereum for elliptic curve addition, scalar multiplication, and pairings (EIP 196, EIP 197), this until the inclusion of EIP-2537.

sandwich bot for Uniswap v2, implemented in Rust & Huff

subway-rs is a port of libevm's original subway, implemented with ethers-rs and huff. Having highly optimized contracts is just one part of the equation, a tech stack is just as important as the contracts to execute on the opportunities. A pure-rust bot used to execute sandwich attacks on UniswapV2. The bot's goal is to act as a low barrier of entry for rust-based MEV development - Reference source code for aspiring new searchers. It's fast.
