Mar 03, 2026 - 18:18 UTC
We will be upgrading our Ethereum consensus (Lighthouse) nodes to the latest stable version (v8.1.1) to incorporate a mandatory security fix along with networking and validator client bug fixes.
Notable changes: --- - Security: Critical security vulnerability fix affecting all prior Lighthouse versions — further details to be disclosed by the Lighthouse team in the coming days
- Bug Fixes: Validator Client — Fixed a regression from `v8.1.0` where the VC head monitoring stream would continuously time out, causing repeated Head service failed warnings. Networking — Fixed duplicate data columns in `DataColumnsByRange` responses caused by skip slots, which was causing peers to downscore nodes with `DuplicatedData` errors. Networking — Snappy decoding errors are now correctly classified as `InvalidData` instead of `IoError`, fixing improper error handling in RPC message decoding. Memory — Fixed a slow memory leak on long-running nodes caused by missing prune calls for the `observed_column_sidecars` cache during finalization Sync — Fixed head chain processing to correctly sort by peer count in descending order, improving sync peer selection
- Networking Improvements: Peers sending invalid RPC requests that result in decoding errors are now penalized and disconnected ---

In effort to ensure quick and reliable performance, we’re initiating a client migration on Binance Smart Chain from the Erigon client to the Reth client. This is expected to completed by February 27.
BSC Testnet has already been migrated, allowing your team to test and observe for any potential issues. While such issues are unlikely, there are a few minor differences to note.
Minor: - `eth_getBlockByNumber`: size field is 1 byte smaller in Reth (may affect some archive assumptions) - Minor formatting differences:`debug_traceBlock` / `trace_block`: error message capitalization (“Out of gas” vs “out of gas”) - eth_feeHistory: returns 0 instead of 0.0
Important: - This migration deprecates all erigon_* methods on BNB Smart Chain, as they are not supported by Reth.

In preparation for the Lisoo/LisovoPro hardfork at block 83756500, we will be upgrading our Polygon nodes.
There are no explicit API method format/signature changes called out for this upgrade.
However, there are a few API-relevant things to be aware of: Bug fixes affecting RPC behavior:
- `eth_simulateV1` - had a crash bug that is now fixed (two separate fixes: one for the method handler, one in consensus/misc/eip4844). If you were working around crashes, behavior may normalize.
- State-sync transactions in tracers - eth_tracers now correctly includes state-sync txs in traces post-Madhugiri HF. If you rely on trace results, output may change for those transactions.
Consensus/fee changes that could affect responses:
- Dynamic EIP-1559 parameters — base fee calculation parameters are now dynamic. This could affect `eth_gasPrice`, `eth_feeHistory`, and related fee estimation calls.
- P256 precompile gas cost update — calls to the P256 precompile (RIP-7212) will now use updated gas costs, affecting gas estimation for transactions using it.
- PIP-82 / BurntContract changes — changes to how fees are burned; shouldn't change API formats but could affect balance/accounting queries.
New opcode:
- CLZ opcode added — relevant if you're doing gas estimation for contracts that use it. The short answer: no breaking changes to API method names or response schemas are documented. The main things to watch are fee estimation behavior (dynamic EIP-1559 params) and tracer output for state-sync transactions. The hardfork hits Mainnet at block 83756500, around 2 PM UTC on March 4, 2026.
