2.5.0 (2026-06-12)

This pre-release introduces Unzen fork support on Taiko-Hoodi network, syncs with go-ethereum v1.17.2, adds a new auth API, and aligns zk gas behavior with alethia-reth.

Hoodi Unzen Fork Time

• Set Hoodi Unzen fork time to 2026-05-21 13:00:00 UTC.
• Unix timestamp: 1789995600.

Flag Changes

• Added --taiko.internal-uzen-time
  • Internal flag for configuring the Unzen fork time.
  • Intended for internal/devnet testing and controlled network rollout scenarios.

Highlights

• Added Unzen fork support:

  • Introduce Unzen zk gas metering, Osaka EVM support, and engine API updates.
  • Use network-specific Unzen zk-gas block limits: 1B for Masaya and 100M for other networks.
  • Set Masaya Unzen fork time to 2026-05-07 13:00:00 UTC.
  • Set Hoodi Unzen fork time to 2026-05-21 13:00:00 UTC.
  • Update Taiko genesis configuration for Masaya and Hoodi Unzen scheduling.

• Improved Unzen zk gas accounting:

  • Include TX_INTRINSIC_ZK_GAS in Unzen zk gas accounting.
  • Match precompile zk-gas multipliers by full address.
  • Add the p256verify zk-gas multiplier.
  • Lower the default Unzen modexp zk-gas multiplier to 154.
  • Recalibrate Unzen zk gas multipliers and freeze the Masaya schedule.
  • Correct Unzen BLS12 precompile addresses and add CLZ opcode support.

• Added API support:

  • Introduce the auth API taikoAuth_lastCertainL1OriginByBatchID.

• Synced upstream:

  • Merge upstream go-ethereum v1.17.2.

• Fixed network and execution behavior:

  • Honor Taiko network ID when selecting genesis.
  • Align Unzen zk-gas accounting.
  • Revert state on zk-gas-exhausted transactions to match alethia-reth.
  • Align Unzen zk gas behavior on memory size overflow.
  • Gate batch lookup results by network.

• Maintenance and testing:

  • Increase the batch lookup window.
  • Update devnet JSON files.
  • Reduce lookup blocks in related tests.
