This release brings over 300 performance enhancements, protocol improvements, and developer-focused upgrades:
- Increase Ethereum Mainnet Gas Limit to 45MGas
- Drop the pre-merge history for Ethereum Mainnet (around 300GB smaller DB)
- Faster block production, sync, and pruning
- New admin RPCs and richer metrics for tracing and debugging
- EIP-4444 and EIP-2935 fixes, plus extended snapshot handling
- Refactors improving stability, modularity, and test coverage
Major highlights
Protocol
- Drop pre-merge history from Ethereum Mainnet
- It gives about 300GB in disk space
- Requires a full resync of a node to have an effect of that
- To preserve them on fresh sync add flags
--Sync.AncientReceiptsBarrier=0and--Sync.AncientBodiesBarrier=0
- RPC error support for EIP-4444 (pruned blocks)
- Fixes for EIP-2935 edge cases
Performance
- A lot of performance improvements which allows now to bump safely gas limit of Ethereum Mainnet to 45 MGas
- Significantly improved local block building and profitability logic
- State sync, pruning, blob fee calc
- Improved memory use by networking and Trie cache
- Parallel block downloading (with rollback safety)
- AVX512 and ARM64-specific boost for 256-bit integer arithmetic
JSON-RPC & metrics
- New JSON-RPC methods:
admin_addTrustedPeer,admin_removeTrustedPeer,admin_peerEvents - More granular metrics:
engine_getBlobsV1, pruning, block stats - Improved Geth-compatible
debug_tracesupport - Default extradata for local building includes Nethermind version (as per Besu, Erigon, Geth)
Chain support
- Updates to OP Superchain, World Chain, Hoodi, Taiko Pacaya
- Snap sync support for Energy Web
- Configuration fixes: deposit contracts, gas limits, ancient block barriers
CLI improvements
Shortened boolean command line option notation. For example, --metrics-enabled true can now be written as --metrics-enabled, omitting the value part. If the value is false, it still must be explicitly specified.
nethermind-cli
nethermind-cli is retired as deprecated. See the docs for suggested replacements.
Other improvements
- Major refactors: pruning, sync, metrics, plugins, discovery
- Plugin system enhancements and modular debug features

v1.31.11
Release notes
Important
This release is a mandatory upgrade for all node operators of OP Stack chains.
OP Stack
Nethermind was rejecting blocks as invalid due to an InvalidWithdrawalsRoot error from multiple different peers. This is now fixed and it is a mandatory upgrade for OP stack node operators.
- Fix Invalid Withdrawals Root when downloading blocks by @emlautarom1 in #8638
Hoodi gas limit increase to 60Mgas
As everything works smoothly on Sepolia after bumping gas limit to 60m and Hoodi also already operates at 60m we add it as a default value for Hoodi which is used by local builders.
Memory leak fixes
- Fix infinite loop in tx pool by @asdacap in #8632
- Fix filter timeouts, set to 15m by @LukaszRozmej in #8633
Taiko-alethia Pacaya hardfork
- Taiko Alethia Pacaya fork activation which happened at Block 1,166,000 at May 21, 2025 UTC by @smartprogrammer93 in #8642
Surge Hoodi
- Add Surge Hoodi chainspec by @smartprogrammer93 in #8643
Other changes

v1.31.10
Release notes
This release is a mandatory upgrade for all node operators of OP Stack chains
Isthmus upgrade
- The Isthmus hard fork of a limited number of OP Stack Mainnet chains is scheduled for May 9, 2025 at 16:00:01 UTC
Sepolia and Holesky gas limit increase to 60Mgas
As we are already post-Pectra on mainnet and after discussion with other Core developers we decided to increase gas limit on Sepolia and Holesky to 60MGas. This also aligns with decisions taken on ACDE 203.
Other changes
- [Optimism] Add support for all Superchain Chains by @emlautarom1 in #8105
- [Taiko] Rename

v1.31.7
v1.31.6
Release notes
This release is recommended for all users operating on Sepolia, Holesky, or Chiado.
Major highlights
Hoodi testnet
Added support for a new testnet—Hoodi with the hoodi and hoodi_archive configurations. For instance:
nethermind -c hoodi --data-dir path/to/data/dir
# or
nethermind -c hoodi_archive --sync-snapsync false --sync-fastsync false --data-dir path/to/data/dirHolesky gas limit increase to 60M
As Holesky is now updated to Pectra and we have Hoodi as a new chain that will imitate the Mainnet closer, we are free to experiment a bit more here, so we decided to try out the 60M gas limit for blocks to see how well those would be handled here.
trace_transaction memory leak fix
Fixed issue #8020, where memory started to grow exponentially under heavy load by the trace_transaction JSON-RPC method, and a node restart was required to bring it back to normal.
What's Changed
- Increase Holesky gas to 60M by @benaadams in #8383
- Fix/1.31.6 trace leak by @kamilchodola in #8388
