Today, we are announcing "Kevlar" (github.com/shresthagrawal…), a tool that makes Metamask, or any RPC-based wallet, completely trustless! Kevlar first runs a light client to quickly sync with the beacon chain and then starts a local RPC proxy that you can add to your wallet

Kudos to Trail of Bits for the great work, highlighting the gap between research and application. Checking the degree of the sharing polynomial might seem "obvious" to the cryptographer, but not to the engineer. This underscores the need for "translational cryptography". 1/4

Apostolos (tzinas) presenting "On-Chain Timestamps Are Accurate" at FC'24. This joint work with Dionysis Zindros and Srivatsan Sridhar proves that timestamps of blockchain blocks do not deviate from real-world time, even in adversarially-produced blocks. 1/2

This property was suspected but never proven before. Yet, billion-dollar DeFi protocols rely on it for their safety, e.g., in dispute period durations. The exact parameters are calculated in this paper: eprint.iacr.org/2023/1648.pdf 2/2

Decentralization is the fundamental concept underpinning all blockchain systems. But what does this mean and how do we measure it? Christina (Christina Ovezik) explains in her talk at FC'24, presenting joint work with Aggelos Kiayias & CP's @dimitKarakostas: arxiv.org/pdf/2211.01291…

Proving an Ethereum PoS block's ancestry is hard. Verifying predecessor blocks without downloading all of Ethereum's ~200MB Beacon state is far from trivial. Inspired by Lodestar's proving API, we built a Rust library that simplifies proving the lineage between two beacon

Everything runs on ledgers — from banks and governments to entire economies. Blockchains can transform them into a global, scientific system of trust. Watch Dionysis Zindros keynote “The Vision of Blockchain” (Panathenea 2025, Athens). 1/3
