 # UNRELEASED
 
 ## New features
+- New ChainIndexer subsystem to index Filecoin chain state such as tipsets, messages, events and ETH transactions for accurate and faster RPC responses. The `ChainIndexer` replaces the existing `MsgIndex`, `EthTxHashLookup` and `EventIndex` implementations in Lotus, which [suffer from a multitude of known problems](https://github.com/filecoin-project/lotus/issues/12293).  If you are an RPC provider or a node operator who uses or exposes Ethereum and/or events APIs, please refer to the [ChainIndexer documentation for operators](./documentation/en/chain-indexer-overview-for-operators.md) for information on how to enable, configure and use the new Indexer.  While there is no automated data migration and one can upgrade and downgrade without backups, there are manual steps that need to be taken to backfill data when upgrading to this Lotus version, or downgrading to the previous version without ChainIndexer. Please be aware that that this feature removes some options in the Lotus configuration file, if these have been set, Lotus will report an error when starting. See the documentation for more information.
 - Return a consistent error when encountering null rounds in ETH RPC method calls. ([filecoin-project/lotus#12655](https://github.com/filecoin-project/lotus/pull/12655))
 - Reduce size of embedded genesis CAR files by removing WASM actor blocks and compressing with zstd. This reduces the `lotus` binary size by approximately 10 MiB. ([filecoin-project/lotus#12439](https://github.com/filecoin-project/lotus/pull/12439))
 - Add ChainSafe operated Calibration archival node to the bootstrap list ([filecoin-project/lotus#12517](https://github.com/filecoin-project/lotus/pull/12517))

+	// the chain index at a specific epoch.
+	//
+	// It can be used to:
+	//
+	// 1. Validate the chain index at a specific epoch:
+	//   - Ensures consistency between indexed data and actual chain state
+	//   - Reports any errors found during validation (i.e. the indexed data does not match the actual chain state, missing data, etc.)
+	//
+	// 2. Optionally backfill missing data:
+	//   - Backfills data if the index is missing information for the specified epoch
+	//   - Backfilling only occurs when the `backfill` parameter is set to `true`
+	//
+	// 3. Detect "holes" in the index:
+	//   - If `backfill` is `false` and the index lacks data for the specified epoch, the API returns an error indicating missing data
+	//
+	// Parameters:
+	//   - epoch: The specific chain epoch for which to validate/backfill the index.
+	//   - backfill: A boolean flag indicating whether to attempt backfilling of missing data if the index does not have data for the
+	//               specified epoch.
+	//
+	// Returns:
+	//   - *types.IndexValidation: A pointer to an IndexValidation struct containing the results of the validation/backfill.
+	//   - error: An error object if the validation/backfill fails. The error message will contain details about the index
+	//            corruption if the call fails because of an incosistency between indexed data and the actual chain state.
+	//            Note: The API returns an error if the index does not have data for the specified epoch and backfill is set to false.
