Taiko RPC: The L2 With No Sequencer

Short summary

Taiko is an Ethereum L2 based rollup (chain ID 167000) with no sequencer—Ethereum's own validators propose blocks, inheriting L1 liveness and censorship resistance. It's also a Type-1 zkEVM, meaning Solidity contracts and standard EVM tooling work with zero changes. Unlike optimistic rollups with 7-day challenge windows, Taiko achieves hard finality in minutes via validity proofs. The trade-off is heavier proof generation, but that burden falls on provers, not application developers.

• •No sequencer: Ethereum validators propose Taiko blocks, inheriting L1 liveness and censorship resistance
• •Type-1 zkEVM means exact Ethereum opcode behavior—Foundry, Hardhat, Viem all work unchanged
• •Hard finality via zk proofs in minutes vs 7-day optimistic challenge windows on OP Stack chains
