NV29 upgrade

Forest joins Lotus and Venus in supporting NV29 Solstice upgrade. See the post for details regarding the new features brought to the network.

To keep Forest nodes running, the operators must upgrade Forest to supporting versions, as outlined in the timeline.

📆 Timeline

timeline
    title NV29 Forest timeline

    Sep 28th (epoch 4109133): Calibration NV29 network upgrade
    ~First-Second Week of Oct: Forest release supporting NV29 for Mainnet

Loading

The timeline is subject to change. Depending on external factors, the Forest release for mainnet will likely arrive faster to give plenty of time for an update.

💻 Hardware requirements

The state migration for this upgrade is minimal. Depending on your hardware, the time to migrate the state will vary.

• calibnet: around 2s

Tip

To lower the time required for the state migration, you can prune the chain data before the upgrade. This is done by removing $HOME/.local/share/forest/mainnet on Linux, or by starting Forest with --import-snapshot <snapshot> --remove-existing-chain on any OS, and importing a fresh snapshot before the upgrade.

An alternative to the automatic state migration is downloading a snapshot from the ChainSafe snapshot service sometime after the upgrade (30m - 2h). Endpoints below:
