Node and Miner v1.31.0 / 2024-12-02

The Lotus v1.31.0 release introduces the new ChainIndexer subsystem, enhancing the indexing of Filecoin chain state for improved RPC performance. Several bug fixes in the block production loop are also included. Please review the upgrade warnings and documentation for any important changes affecting RPC providers, node operators and storage providers.

⭐ New Feature Highlights:

  • 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. 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 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
  • lotus chain head now supports a --height flag to print just the epoch number of the current chain head (filecoin-project/lotus#12609)
  • Implement EthGetTransactionByBlockNumberAndIndex (eth_getTransactionByBlockNumberAndIndex) and EthGetTransactionByBlockHashAndIndex (eth_getTransactionByBlockHashAndIndex) methods. (filecoin-project/lotus#12618)
  • lotus-shed indexes inspect-indexes now performs a comprehensive comparison of the event index data for each message by comparing the AMT root CID from the message receipt with the root of a reconstructed AMT. Previously inspect-indexes simply compared event counts. Comparing AMT roots instead confirms all the event data is byte-perfect. (filecoin-project/lotus#12570)
  • Return a "data" field on the "error" returned from RPC when eth_call and eth_estimateGas APIs encounter execution reverted errors. This is a standard expectation of Ethereum RPC tooling and may improve compatibility in some cases. (filecoin-project/lotus#12553)
  • Improve ETH-filter performance for nodes serving many clients. (filecoin-project/lotus#12603)
  • Implement F3 utility CLIs to list the power table for a given instance and sum the proportional power of a set of actors that participate in a given instance. (filecoin-project/lotus#12698)

🐛 Bug Fix Highlights

  • Add logic to check if the miner's owner address is delegated (f4 address). If it is delegated, the lotus-shed sectors termination-estimate command now sends the termination state call using the worker ID. This fix resolves the issue where termination-estimate did not function correctly for miners with delegated owner addresses. (filecoin-project/lotus#12569)
  • The Lotus Miner will now always mine on the latest chain head returned by lotus, even if that head has less "weight" than the previously seen head. This is necessary because F3 may end up finalizing a tipset with a lower weight, although this situation should be rare on the Filecoin mainnet. (filecoin-project/lotus#12659) and (filecoin-project/lotus#12690)
  • Make the ordering of event output for eth_ APIs and GetActorEventsRaw consistent, sorting ascending on: epoch, message index, event index and original event entry order. (filecoin-project/lotus#12623)
  • Return a consistent error when encountering null rounds in ETH RPC method calls. (filecoin-project/lotus#12655)
  • Correct erroneous sector QAP-calculation upon sector extension in lotus-miner cli. (filecoin-project/lotus#12720)

Node and Miner v1.30.0 / 2024-11-06

This is the final release of the MANDATORY Lotus v1.30.0 release, which delivers the Filecoin network version 24, codenamed Tuk Tuk 🛺. This release sets the Mainnet to upgrade at epoch 4461240, corresponding to 2024-11-20T23:00:00Z.

  • If you are running the v1.28.x version of Lotus, please go through the Upgrade Warnings section for the v1.28.* releases and v1.29.*, before upgrading to this release.
  • This release requires a minimum Go version of v1.22.7 or higher.
  • The releases branch has been deprecated with the 202408 split of 'Lotus Node' and 'Lotus Miner'. See https://github.com/filecoin-project/lotus/blob/master/LOTUS_RELEASE_FLOW.md#why-is-the-releases-branch-deprecated-and-what-are-alternatives for more info and alternatives for getting the latest release for both the 'Lotus Node' and 'Lotus Miner' based on the Branch and Tag Strategy.
    • To get the latest Lotus Node tag: git tag -l 'v*' | sort -V -r | head -n 1
    • To get the latest Lotus Miner tag: git tag -l 'miner/v*' | sort -V -r | head -n 1

🏛️ Filecoin network version 24 FIPs

⚠️ The activation of F3 (Fast Finality) has been postponed for mainnet due to unresolved issues in the Client/SP code and the F3 protocol itself. These issues require further testing and resolution before we can safely deploy F3 on the mainnet. Read the full post here.

📦 v15 Builtin Actor Bundle

The v15.0.0 actor bundle is used for supporting this upgrade. Make sure that your Lotus actor bundle matches the v15 actors manifest by running the following cli after upgrading to this release:

lotus state actor-cids --network-version=24
Network Version: 24
Actor Version: 15
Manifest CID: bafy2bzaceakwje2hyinucrhgtsfo44p54iw4g6otbv5ghov65vajhxgntr53u

🚚 Migration

All node operators, including storage providers, should be aware that ONE pre-migration is being scheduled 120 epochs before the network upgrade. The migration for the NV24 upgrade is expected to be light with no heavy pre-migrations:

  • Pre-Migration is expected to take less then 1 minute.
  • The migration on the upgrade epoch is expected to take less than 30 seconds on a node with a NVMe-drive and a newer CPU. For nodes running on slower disks/CPU, it is still expected to take less then 1 minute.
  • RAM usages is expected to be under 20GiB RAM for both the pre-migration and migration.

We recommend node operators (who haven't enabled splitstore discard mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade.

For certain node operators, such as full archival nodes or systems that need to keep large amounts of state (RPC providers), we recommend skipping the pre-migration and run the non-cached migration (i.e., just running the migration at the network upgrade epoch), and schedule for some additional downtime. Operators of such nodes can read the How to disable premigration in network upgrade tutorial.
