Encrypted Mempools

We're excited to announce that Shutter and Primev are partnering to bring the first threshold encrypted mempool to Ethereum's out-of-protocol transaction supply chain, PBS (Proposer-Builder Separation). This integration targets the long standing issue of front running, sandwich attacks, and real-time censorship across the PBS pathway, which

Explore how Shutter uses threshold encryption to fight MEV, its strengths and trade-offs.

We’ve Seen This Before. It’s Happening Again. In 2014, Michael Lewis published a book called Flash Boys. It pulled back the curtain on Wall Street’s dirty little secret: a small group of trading firms had rigged the game. They spent millions on faster cables and servers so

We're excited to share some big news: Erigon’s 3.1.0 Pebble Paw release now officially supports Shutter’s encrypted mempool on the Gnosis chain in addition to the Nethermind client. Erigon is a high-performance Ethereum execution client, and this update makes it easier than ever for

This article provides insights on proposing encrypted mempools in various environments, offering a practical framework tailored to your context.

Ethereum’s public mempool has always been a double-edged sword.  On one hand, it reflects the openness of the network and allows for auditability. On the other, that same openness creates an “exploit window,” where pending transactions can be seen and acted upon before they’re finalized. This fuels harmful

Myths and misconceptions about encrypted mempools can hinder adoption and obscure the value that they offer to Ethereum and its users.

Ethereum's $1 trillion security initiative aims to attract institutional capital, but the chain’s transparent mempool enables $1.8 billion in malicious MEV extraction.

Glamsterdam is Ethereum’s next big upgrade - and a chance to dramatically improve decentralization and censorship resistance. Shutter supports prioritizing EIP-7732 (ePBS) and EIP-7805 (FOCIL), with encrypted mempools and silent threshold encryption proposed as powerful future implementations.
