v3.5.0

Compare Source

Erigon 3.5.0 is a major release headlined by parallel block execution becoming the default and initial support for Ethereum's upcoming Glamsterdam hardfork. It is a drop-in upgrade for 3.4.x users — no re-sync required; existing datadirs upgrade their prune configuration automatically (see Breaking Changes).

Key Features

• Parallel block execution, on by default. Erigon now executes EVM transactions across multiple cores by default, using the Block-STM (software transactional memory) design pioneered by Aptos: transactions run optimistically in parallel and are re-validated against a multi-version state, re-executing only on conflict (#​21591 by @​mh0lt, closes #​17630). Revert to serial with EXEC3_PARALLEL=false or --exec.serial.
• Glamsterdam devnet support. Initial implementation of Ethereum's next hardfork: Block-Level Access Lists (EIP-7928), enshrined Proposer-Builder Separation / "Gloas" (EIP-7732) in Caplin, gas repricings (EIP-8037, EIP-7976, EIP-7981), larger contracts (EIP-7954), transfer logs (EIP-7708), and the eth/71 Block Access List wire protocol (EIP-8159). Devnet/testing only — not scheduled on mainnet or any public testnet.
• debug_executionWitness. Stateless execution-witness generation (EIP-7928/8025) with reth-compatible output, for zkEVM and stateless clients (#​20205 by @​antonis19, #​21629 by @​awskii).
• More aggressive history pruning by default. --prune.mode=full now follows the EIP-8252 reorg-retention window (~36 days / 262,144 blocks) — see Breaking Changes.
• GraphQL API revival. Broad resolver coverage restored — queries, logs, call, sendRawTransaction, estimateGas, gasPrice, storage, and EIP-4844 fields.

Breaking Changes

--prune.mode=full: EIP-8252 retention window replaces pre-merge history-expiry

Full mode now retains state and block data for the last 262,144 blocks (~36.4 days), matching EIP-8252's REORG_RETENTION_WINDOW (#​21342). Previously full mode pruned only pre-merge block data (EIP-4444 history-expiry) and kept the last 100,000 blocks of state history.

What changed:

	Before	After
State history retention	last 100,000 blocks	last 262,144 blocks
Block data retention	pre-merge pruned, all post-merge kept (EIP-4444)	last 262,144 blocks

Migration: existing datadirs upgrade automatically and silently. To keep the old "retain all post-merge block data" behavior, set --prune.distance.blocks=18446744073709551615.

Note: physical deletion of frozen snapshot files is not implemented yet (see #​21306), so existing on-disk historical blocks persist for now, though the new cutoff is already recorded at the config level.

In practice, this means only freshly synced full nodes will have a reduced disk footprint.

--prune.mode=blocks: state history retention bumped to 262,144 blocks

--prune.mode=blocks keeps the same shape as before (all block data retained), but its state history retention also bumps from 100,000 to 262,144 blocks. --prune.mode=minimal is unchanged — both block and state history retain the 100,000-block window, deliberately sub-EIP-8252 for disk-constrained operators. See #​21342 for details.

Single p2p listener: --p2p.allowed-ports removed, all eth versions multiplex on --port

Erigon now opens a single TCP listener on --port (default 30303) carrying every configured eth protocol version, instead of one listener per protocol on 30303/30304/30305. This fixes a discovery-DHT race that left inbound peers stuck at a fraction of --maxpeers for multi-protocol deployments: per-protocol ENRs collided under one Node ID, so only one survived in the DHT and peers dialed the wrong listener (#​21335).

What changed:

Aspect	Before	After
Inbound peer ports	30303, 30304, 30305, … (one per eth version)	30303 only
--p2p.allowed-ports flag	Picked one port per protocol from this list	Removed — passing it now errors
--maxpeers semantics	Per-protocol cap; actual ceiling ≈ N × maxpeers	Honest total cap
Default --maxpeers	32	64 (compensates for the now-honest cap)
Enode database directory	<datadir>/nodes/eth68, <datadir>/nodes/eth69, …	<datadir>/nodes/eth

Migration:

• Remove --p2p.allowed-ports=... from CLI args / config files; it is no longer recognised.
• Firewall, Kubernetes Service, and monitoring rules that explicitly opened 30304/30305 can drop those entries — only --port is bound now.
• If you previously lowered --maxpeers because you knew the per-protocol multiplication inflated the real ceiling, raise it back to the target total (the cap is now what the flag says).
• First run after upgrade loses the warm peer cache in nodes/eth{68,69,…} — nothing on disk is deleted, the directories are simply no longer read; discovery rebuilds the peer set from bootnodes within a few minutes.

Standalone sentry binary (cmd/sentry) and --sentry.api.addr (remote sentry over gRPC) are unaffected — neither had the bug.

debug_trace* RPC: enableMemory / enableReturnData replace disableMemory / disableReturnData

Aligns Erigon with the execution-apis specification (ethereum/execution-apis#762) and Geth behavior.

What changed:

Field	Before (Erigon)	After (Erigon / Geth / Spec)
Memory in trace	disableMemory (default: included)	enableMemory (default: excluded)
Return data in trace	disableReturnData (default: included)	enableReturnData (default: excluded)

Both the key and its default changed: disable* → enable*, and memory and return data are now excluded unless explicitly enabled — matching the spec and Geth.

Migration: memory and return data are now excluded by default. To include them, add the new opt-in key (omit it to keep the default):

• Memory: { "enableMemory": true }
• Return data: { "enableReturnData": true }

Affected RPC methods: debug_traceTransaction, debug_traceBlockByHash, debug_traceBlockByNumber, debug_traceCall.

---

Clique PoA consensus engine removed

The legacy Clique proof-of-authority engine has been removed (#​20532 by @​yperbasis). --chain=dev now runs on an embedded proof-of-stake consensus instead of Clique (#​20451 by @​mh0lt), matching how all live networks operate post-Merge. Networks or tooling that still depended on Clique are no longer supported.

---

Silkworm integration removed

The optional Silkworm C++ execution-backend integration and its --silkworm.* flags have been removed (#​19662 by @​canepat). Erigon uses its native Go execution engine exclusively.

---

Glamsterdam (Devnet Support)

3.5.0 adds an initial implementation of Ethereum's next hardfork — Glamsterdam (consensus-layer "Gloas" + execution-layer "Amsterdam") — for devnet testing and validation. It is not scheduled on mainnet or any public testnet, and these code paths are inert on production networks until an activation time is configured.

v1.17.4: Flexible Polymer Casing (v1.17.4)

Compare Source

This is a maintenance release with accumulated bug fixes and improvements, and is recommended for all users. It also continues the implementation work for the upcoming Amsterdam hardfork.

One thing worth highlighting:

• Clef has been removed. The standalone clef signer has moved to https://github.com/ethereum/clef (#​35097).

Fork Implementation (Amsterdam)

v8.2.0: Mr. Goldenfold

Compare Source

Summary

⚠️ Lighthouse v8.2.0 is a high-priority release containing fixes for several security vulnerabilities, as well as optimisations and new features.

All beacon node users should upgrade as soon as practical. Validator client users should review the fee-recipient and graffiti changes below before upgrading.

This release also contains substantial Gloas preparation, Fulu data-availability networking improvements, and new standard API support.

Upgrade Notes

• Mandatory fee recipient: Validator clients now refuse to startup when an enabled validator has no suggested_fee_recipient field in validator_definitions.yml and no global --suggested-fee-recipient fallback is configured. This prevents validator income from being lost accidentally.
• Validator graffiti: Lighthouse beacon nodes now append client version information to user graffiti by default. To opt-out use the --graffiti-append false flag with Lighthouse VC or set graffiti that is between 30-32 bytes long. There is no change in behaviour if you are already using the --private flag for the beacon node.
• 💾 Database schema v29: Lighthouse beacon nodes will automatically migrate the database from schema v28 to v29 on startup. A downgrade back to v28 is available prior to the Gloas hard fork, follow the instructions in the [Lighthouse Book](https://lighthouse-book.sigmaprime.io/advanced_
