Espresso Systems: Shared Sequencing and Privacy for L2 Rollups
Espresso Systems is building shared sequencing and privacy infrastructure for Ethereum L2 rollups — a sequencer marketplace that multiple rollups can use to get MEV protection, fast finality, and cross-rollup atomicity. Positioned at the intersection of rollup scaling and the decentralized sequencer problem.
Notes on Ethereum L2 Solutions
Jin's 2021 notes on Ethereum L2 scaling solutions — covering optimistic rollups, ZK-rollups, state channels, and plasma. A solid survey of the L2 design space written before rollups became the dominant paradigm.
L2BEAT: The State of the Layer Two Ecosystem
L2BEAT tracks TVL and security risk across all Ethereum Layer 2 solutions — classifying each by how much trust is required (training wheels vs. fully trustless). The most authoritative public resource for comparing the actual security properties of different L2s.
Exploring Zero Knowledge: zkSync and the zkEVM
An explainer on zkSync and the zkEVM — how zero-knowledge proofs enable EVM-compatible rollups that give instant finality without trusting the operator. Written in early 2022 as zkEVM was the most technically ambitious open problem in Ethereum scaling.
