Shared Sequencing, the Next Step toward Decentralizing Rollups
summary
Explains a working prototype of a shared sequencer built on a new Hot Shot consensus that targets tens of thousands of nodes and «optimistic responsiveness» for near-network finality while assuming 2/3 honest validators; shows how a shared layer makes atomic cross-rollup inclusion possible and raises the bar on bridge-revert attacks. Compares that to an encrypted ZK rollup approach (private + public txs) and an encrypted mempool + ZK-validity model to eliminate MEV/censorship; reports ~10 RFP submissions and one concrete “espresso Martini” pre-confirmation design.
