zkSync Era block time is 1.55 s (p50, 24h). zkSync Era is a zk-rollup with a Matter Labs-operated sequencer; block production is batched because the prover must generate a SNARK before the batch is finalized on Ethereum, so within a busy burst blocks land near 1 s but the median drifts up during quiet periods when the sequencer waits to fill a batch. Measured via the `era.zksync.io/ws` WebSocket and `newHeads` inter-arrival deltas.
