filecoin-project/lotus v1.28.0-rc2

on GitHub

This is the second release candidate of the upcoming MANDATORY Lotus v1.28.0 release, which will deliver the Filecoin network version 23, codenamed Waffle 🧇.

This release candidate sets the calibration network to upgrade at epoch 1779094, corresponding to 2024-07-11T12:00:00Z. This release does NOT set the mainnet upgrade epoch yet, in which will be updated in the final release.

☢️ Upgrade Warnings ☢️

• If you are running the v1.26.x or an earlier version of Lotus, please go through the Upgrade Warnings section for the v1.27.* releases, before upgrading to this RC.
• This upgrade includes an additional migration to the events database. Node operators running Lotus with events turned on (off by default) may experience some delay in initial start-up of Lotus as a minor database migration takes place. See filecoin-project/lotus#12080 for full details.

The Filecoin network version 23 delivers the following FIPs:

• FIP-0065: Ignore built-in market locked balance in circulating supply calculation
• FIP-0079: Add BLS Aggregate Signatures to FVM
• FIP-0084: Remove Storage Miner Actor Method ProveCommitSectors
• FIP-0085: Convert f090 Mining Reserve Actor to Keyless Account Actor
• FIP-0091: Add support for legacy Ethereum transactions
• FIP-0092: NI-PoRep
• FIP-0086: Fast Finality Soft Launch

Note that we are only doing a "soft launch"/"passive testing" for F3 (Fast Finality) i.e. FIP-0086 in NV23. Please see this doc for more details.

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 NV23 upgrade is expected to be light with no heavy pre-migrations, here are some expected timings and resource consumption numbers:

• Pre-Migration is expected to take less then 1 minute
• The migration is expected to take less then 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.

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.
