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

Our very own Dionysis Zindros presenting "Light Clients for Lazy Blockchains," a paper describing how to construct a light client for "optimistic" chains like @CelestiaOrg. A collective effort alongside @ErtemTas, David Tse, and Lei Yang Σ:. 1/2

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…

The Common Prefix team is in Athens for ZK Summit, by Zero Knowledge Podcast. Looking forward to discussing all things Zero Knowledge with the thought leaders of ZK research and implementation!🪄

Shresth (shresth) giving a talk at #zksummit11 about common pitfalls and optimizations for modern cryptographic protocol implementations.

For those who couldn't make it in person, here's the recording of shresth's talk: youtu.be/5qy0AWTrjjI

In the past year, we've collaborated with BabylonChain on their mission to bring Bitcoin Staking to the world: stake your bitcoins right from the Bitcoin chain and help secure the Cosmos ecosystem! 🧵 1/4

PoW vs PoS: Can wealth truly replace work in securing blockchains? Let's dive into why Proof-of-Work may be the key to more robust and secure blockchain systems. 1/5

We've curated our researchers' publications: commonprefix.com/research. Evidently, our scientists have been busy. Happy reading.

CJ taking the stage at Apex 2025, talking about Formerly Axelar, now at @axelar and the upcoming integration with XRPL.

Our team will be flying over to Brussels to attend EthCC - Ethereum Community Conference and @modular_summit, coming up in a few days. DM us if you'll be there and would like to talk!

We're looking to onboard Senior Software Engineers with blockchain experience: commonprefix.notion.site/Opening-Senior… If you think you're a good fit, please email your CV, GitHub handle, and transcript (if you graduated within the past 5 years) to [email protected].

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
