Taiko is a decentralized Ethereum-equivalent ZK-EVM and general-purpose ZK-Rollup.
Taiko released taiko-geth v2.7.0, a mandatory, consensus-sensitive execution-engine upgrade for node runners on both networks. The release fixes EIP-4788 beacon-roots system-call handling when building Unzen blocks, aligning block building with the import path to prevent state-root mismatches once the beacon-roots contract is deployed.
It sets the canonical zero parent beacon root before execution, rejects non-zero roots during block building and header validation, and drops built-in Masaya network support. Nodes deriving blocks from L1 — not just block producers — must upgrade; runners already on alethia-reth need no changes, and Taiko repeats its recommendation to switch to alethia-reth for ongoing node operation.
Taiko's Security Council Proposal #39 is approved and now sits in the community veto window for roughly 10 days. It upgrades the Bridge and ERC20Vault, and per Taiko's walkthrough it targets a bridging bug exposed by EIP-8037 ("Glamsterdam" storage pricing): creating a new storage slot now costs 97,920 gas while the bridge forwarded only 35,000 when paying out Ether, refunds, unused fees, recalls, and relayer fees. A smart wallet writing one storage slot on receipt runs out of gas, and the failed payout reverts the whole call.
The proposal also adds opt-in permit and Permit2 transfers so no separate approve transaction is needed (existing sendToken behavior is unchanged), and fixes a live bug where the first transfer to L1 of an L2-native token with no L1 counterpart failed since June. Taiko notes two other Security Council proposals executed this month: #37 bumped Raiko verifiers to v0.8.0, cutting Risc0 proving cycles, and #38 restructured the Security Council.
Taiko DAO's Security Council Proposal #24 is open, with TAIKO holders having roughly a 10-day window to veto it. The proposal upgrades four proxies — the Bridge and ERC20Vault on both Ethereum and Taiko — and registers a new resolver on L2. No new contract code ships with the update.
Taiko's CTO Gus Gonzalez is stepping down from his role, as announced by the project on X. The team thanked him for building the rollup's engineering foundation. Gonzalez will remain part of the Taiko ecosystem as an advisor. A replacement CTO was not announced in the post.
The Pheasant Super App launched on Taiko, providing a single AI-powered interface for on-chain interactions. Users tell Pheasant what they want and it converts that intent into on-chain execution, which Taiko promoted as "tAIko."
Taiko enabled Unzen on mainnet, making a ZK proof mandatory for every block. No single proof system can finalize the chain on its own going forward — Validity Proofs are enforced at the protocol level, giving the rollup verifiable and always-on ZK security that runs on mainnet today.
Gus Gonzalez stepped down as CTO of Taiko and moved to an advisor role. He had been responsible for building the rollup's engineering foundation.
Taiko activated Unzen, requiring a ZK (Validity) proof for every block, enforced at the protocol level.
The TAIKO token launched with a Phase 1 genesis airdrop of 5% of the initial supply (~50 million tokens) to eligible users, claimable from June 5 to July 5, 2024.
Taiko was deployed on Ethereum mainnet as the first based rollup, with Ethereum co-founder Vitalik Buterin proposing the inaugural block.
Ahead of its mainnet launch, Taiko announced a $15 million Series A round led by Lightspeed Faction, Hashed, Generative Ventures and Token Bay Capital, bringing total funding to $37 million.
Taiko launched Katla, its sixth and final testnet, implementing the Based Contestable Rollup design with a multi-proof system, ahead of its planned mainnet release.
Taiko Labs announced it had raised $22 million in two seed rounds, including a $10 million round led by Sequoia China and a $12 million round led by Generative Ventures, to build its Ethereum-equivalent Type 1 zkEVM.
