OP Stack Deep Dive
summary
Workshop deep-dives OP Stack architecture and hacking points: op-node + op-geth split, a sequencer producing an unsafe chain every two seconds while L1 advances ~6s, an op-batcher that submits batches as 5–6 blobs ≈130KB each to L1, and a proposer that posts output roots for withdrawals. Local testing uses the monorepo, Docker and make devnet up exposing L2 on 9545 and L1 on 8545. Extensions covered: DA server abstraction (S3/file), adding custom pre-compiles, bridge patterns and instructions to make it your own on a local devnet.
