Secure your sequencer with Espresso 🔐

Hypothetical scenario… We trust the orgs running the major L2s, but what if Lazarus compromised a sequencer? The sequencer can’t steal your funds, but it can arbitrarily re-arrange or remove txns between state commitments. Potentially billions of MEV in those windows?

Decentralized, shared sequencing is finally real. It’s been awesome working with the Caldera team on this release and amazing to see the extensive infrastructure they’ve built for rollups.
