Erigon v3.5.1 — Tidal Tails

v3.5.1 is a bugfix release recommended for all users. It is a drop-in upgrade from 3.5.0 — no re-sync required.

Bugfixes

• execution/stagedsync: fix parallel-execution commitment consistency at step boundaries (#22111, #22135, #22147, #22094) by @awskii, @sudeepdino008 — a block straddling a step boundary left that step's commitment inconsistent with the account/storage/code domains, so published snapshots could mis-serve state-read RPCs (eth_getProof, debug_executionWitness) and, on a later run, wedge the Execution stage in a zero-progress loop with nothing logged. Closes #21992, #22101.
• execution/stagedsync: fix log index reset and missing WebSocket notifications in parallel execution (#22155) by @Sahil-4555 — restores logs / newHeads subscription notifications and correct log indexing when executing in parallel.
• execution/stagedsync: fix pruning in stage_custom_trace (#22052) by @sudeepdino008 — regenerated domains were never pruned and accumulated unbounded in the DB. Closes #22013.
• cl/persistence: fix caplin historical state reconstruction loop at the Bellatrix transition (#22370) by @Sahil-4555 — a Caplin node could stop advancing at the Merge (Bellatrix) slot; pre-Merge blocks carry an all-zero execution payload header, and reconstruction now detects the zero block hash and skips the EL transaction lookup. Closes #22337.
• cl/phase1/forkchoice: replace latestMessagesStore interning with a flat per-validator slice (#22355) by @lystopad — the prune scan walked the whole message map on every update and stalled GetHead past the attestation deadline. Closes #22351.
• cl/antiquary: commit reconstructed state in bounded batches (#22348) by @awskii — committing up to 30 minutes of replayed beacon state in a single MDBX transaction could overflow libmdbx and crash on large (100+ GB) archive databases.
• cl: bound caplin archive blob-column backfill so it can't wedge on Fulu (#22318) by @awskii — prevents an archive node from getting stuck while backfilling blob (data-column) sidecars.
• cl, db/snapshotsync: caplin snapshot correctness — don't freeze empty block/state roots (#22323) and remove overlapping state snapshots on retire (#22317) by @awskii.
• cl: allow boundary attestations while head state lags (#22251) by @domiwei — fixes attestation validation at epoch boundaries when the wall-clock slot has advanced but the head state briefly lags behind.
• rpc/jsonrpc: gate debug_executionWitness on keys[] completeness and keep preimages for in-block-deleted accounts (#22320) by @awskii — avoids returning an incomplete witness.
• rpc: remove the state-history check from block-data-only endpoints (#22073) by @Sahil-4555 — endpoints that only need block data no longer error on nodes pruned below the requested block's state history.
• cmd/utils: allow snapshot reset on upgraded datadirs by restricting the table config (#22291) by @Sahil-4555 — snapshot reset failed to resolve the chain name on upgraded datadirs. Closes #22275.

Improvements

• execution: disable gzip compression for the Engine API (#22369) by @taratorio — removes compression overhead on engine_* responses, lowering engine_getPayload / getBlobs latency.
• p2p: re-resolve the STUN external IP at runtime (#22188) by @lystopad — with --nat=stun, a node whose public IP changes while running now re-resolves and re-advertises it instead of keeping the stale startup value.
• db/version: relax the minor-version check in Supports (#22205) by @sudeepdino008 — a newer, backward-readable minor version within a supported major is now accepted, so the binary won't refuse newer minor-versioned files.
