This release prepares the Hoodi testnet for the Amsterdam hard fork, scheduled for activation at block timestamp 1793036568 (Mon, 26 Oct 2026 17:42:48 UTC). All users on the Hoodi testnet are recommended to upgrade.
A major highlight of this release is a significant performance boost to the EVM. The interpreter's opcode dispatching is now approximately 16% faster due to a new inlined switch implementation. Additionally, state history committing has been moved to a background process, resulting in a 2% speed improvement for newPayload calls.
Key improvements and fixes include:
Core & Geth
- A new --history.transactions flag allows archive node operators to configure the transaction index history.
- Several critical fixes have been implemented to prevent database corruption during power failures.
- Blsync now supports the Gloas beacon chain fork.
- A bug was fixed in the trie database related to concurrent state reading.
Networking
- Resolved an issue that could cause snap sync to restart by correctly checking for pivot block reorgs.
- Fixed a potential mempool corruption when the tip block was below the base fee.
RPC
- RPC methods like eth_call and historical calls will now correctly reject transactions or fields that are not aligned with the active fork rules.
- The eth_simulateV1 endpoint has received several fixes to improve spec compliance.
- eth_newFilter now correctly accepts the earliest tag in the toBlock parameter.
This release enables the Amsterdam fork 🦩 on the Hoodi testnet at block timestamp **1793036568 (Mon, 26 Oct 2026 17:42:48 UTC)**. It also contains changes to the EVM to improve the performance significantly. This release is recommended for all users running their nodes on the Hoodi testnet. ## Geth - Blsync now supports the Gloas beacon chain fork and had some bug fixes (#35956, #35385, #35957) - When running an archive node, you can now configure the transaction index history using `--history.transactions` flag. (#35907) ## Core - Amsterdam fork is set to activate at block timestamp 1793036568. (#35974) - EVM interpreter opcode dispatching became 16% faster due to a new inlined switch implementation. (#35638) - Several fixes for database corruption on power failure (#35939, #35936) - Bug fix in trie database related to concurrent state reading (#35978) - RPC call concurrent with block processing could result in BAL corruption. (#35905) - State history committing is moved to the background, making `newPayload` 2% faster. (#35949) - Key-value database settings changed for improved write performance (#35691) - Fixed log index under history pruning beyond the checkpoint (#35875) ## Networking - Fixed snap/2 restart issue by checking for pivot block reorg in the header chain (#35930, #35982) - Added metrics to discovery listeners (#35673) - Fixed mempool corruption with tip below base fee (#35988) ## RPC - `eth_simulateV1` spec compliance fixes (#35841, #35842, #35953) - `eth_call` and similar methods will reject fields which are not aligned with forks - `eth_fillTransaction` always chooses AccessList transaction when `accessList` is provided by user. (#35969) - `eth_newFilter` now accepts `earliest` in `toBlock`. (#35933) - `eth_sendTransaction` rejects invalid `yParity` value in 7702 transactions. (#35761) - In `debug_traceTransaction`, `debug_traceCall`, omit storage on halted SLOAD/SSTORE steps. (#35961) - Pending block access was fixed on the Amsterdam fork transition block. (#35968) - Historical RPC calls will reject transaction features which have not yet activated.
