More Chains, More Problems: Fixing Interop and Reorgs?
summary
Thousands of new rollups create a rising chance that a single sequencer compromise drains value, so Espresso builds a confirmation layer that claims 5 seconds finality using the HotShot consensus property called optimistic responsiveness. Mainnet is live (permissioned) since November with about 100 nodes 22 validators, testnet “decaf” upgraded to proof‑of‑stake, and the system accepts EVM/ALVM chains for DA or as an optional decentralized sequencer to prevent reorgs and speed bridging.
