On the official site of Corn (@cornkry), this note covers Erigon.
Release On GitHub
Developers checking the GitHub page for the Ethereum execution client saw a new release tag appear on October 20, 2026. The version carried the number 3.8.0. The client itself comes from Erigon.
The Ethereum execution client v3.8.0, released on Oct. 20, 2026, spread commitment work across parallel workers and made batched database syncing the default.
Commitment Handling
Erigon spread deferred commitment writes across parallel workers. Trie updates were prepared at the same time as execution. This approach kept the work moving without single-thread bottlenecks.
Database Sync Update
Erigon made batched database syncing the default. Disk-flush pauses dropped as a result. The change affected how the client handled ongoing chain data.
RPC Adjustments
Erigon streamed trace output for users. State caching returned for embedded RPC calls at the chain tip. These steps supported queries that run close to the latest block.
Transaction Pool Additions
Erigon built blob sidecars inside eth_fillTransaction. Missing KZG commitments and proofs were computed during the same step. A readable txpool_inspect summary now covers pending and queued non-blob transactions.
Erigon returned pending transactions from the pool when eth_getRawTransactionByHash was called. The eth_sendRawTransactionSync method gained the ability to locate receipts for transactions mined before the subscription started.
Consensus Layer Work
Erigon's Caplin consensus layer fetched missing custody columns within the slot. Blobs were recovered in parallel during the same process.
Overall Scope
All items listed above sit inside the single release dated October 20, 2026. The client remains published on GitHub.
How The Changes Fit Together
Parallel commitment writes sit alongside the batched sync default. RPC streaming and caching support queries that need recent state. Transaction pool summaries and receipt lookup extend the set of available calls. Caplin adjustments keep custody and blob recovery inside the slot window.
Each of these pieces targets execution, RPC, or consensus areas. The release date anchors every detail to October 20, 2026. The GitHub page holds the full set of notes for the version.
