Selected Writing / Research

I occasionally write about the topics which interest me the most in crypto:

Ethereum Reorgs after the Merge, with Vitalik Buterin: We investigate chain reorganizations in Proof of Work Ethereum and explain how they are affected by the Proof of Stake transition.
Ethereum is a Dark Forest, with Dan Robinson: We narrate our experience trying to whitehat rescue $12,000 and failing due to being frontrun by a generalized Ethereum mempool bot, a horror story about MEV.
On Staking Pools and Staking Derivatives, with Hasu: We unpack how decentralized staking pools and staking derivatives work, and their impact on their underlying Proof of Stake protocols
(Almost) Everything you wanted to know about Optimistic Rollup Deriving Optimistic Rollups from first principles in a socratic dialogue.
Ethereum Blockspace - Who gets What and Why, with Leo Zhang: We analyze the evolving market dynamics around Ethereum's blockspace.
EIP1559 Series, with Hasu: We analyzed the base mechanics under EIP1559 & its main alternative, bounded the change in miner income as a result of 1559, and finally predicted why the proposal would get activated without any problem (which it did, 6 months later).

I am a big proponent of writing software in the Rust programming language for safety, performance and portability:

foundry: Foundry is a blazing fast, portable and modular toolkit for Ethereum application development. It is a rewrite of dapptools
ethers-rs: Complete library and wallet implementation for interacting with EVM-compatible blockchains, focused in modularity and ergonomics.
opensea-rs: Client to Opensea's APIs and Ethereum smart contracts with Fireblocks and Flashbots support.
mev-inspect-rs: Blazing fast historical MEV discoverer, the first backend of MEV Explore (now replaced by mev-inspect-py)
darkforest-rs and ark-circom: Headless client to Dark Forest, along with an arkworks <> circom library.
