This is an optional but highly recommended feature release of Lotus, as it includes fixes for synchronizations issues that node operators have experienced.

This feature release also introduces the new Lotus-Provider binary in its alpha testing phase, as well as the ability to call external PC2-binaries during the sealing process - read more about these features in the highlights section.

☢️ Upgrade Warnings ☢️

  • You might see a install: cannot stat './lotus-provider': No such file or directory error when running sudo make install building from source. It will not cause any issues, but you can get rid of the error by running make lotus-provider

⭐️ Highlights ⭐️

Lotus-Provider

The feature release ships the alpha release of the new Lotus-Provider binary, together with its initial features - High Availability of WindowPoSt and WinningPoSt.

So what is so exciting about Lotus-Provider:

High Availability

  • You can run as many Lotus-Provider instances as you want for both WindowPoSt and WinningPOSt.
  • You can connect them to as many clustered Yugabyte instances as you want to. This allows for an NxN configuration where all instances can communicate with all others.
  • You have the option to connect different instances to different chain daemons.

Simplicity

  • Once the configuration is in the database, setting up a new machine with Lotus-Provider is straightforward. Simply start the binary with the correct flags to find YugabyteDB and specify which configuration layers it should use.

Durability

  • Lotus-Provider is designed with robustness in mind. Updates to the system are handled seamlessly, ensuring that performance and stability are maintained when taking down machines in your cluster for updates.

External PC2-binaries

In this feature release, storage providers can call external PC2-binaries during the sealing process. This allows storage providers to leverage the SupraSeal PC2 binary, which has been shown to improve sealing speed in the PC2-phase. For instance, our current benchmarks show that an NVIDIA RTX A5000 card was able to complete PC2 in approximately 2.5 minutes.

We have verified that SupraSeal PC2 functions properly with Committed Capacity (CC) sectors, both SyntheticPoReps and non-Synthetic PoReps. However calling SupraSeal PC2 with deal sectors is not supported in this feature release.

For more information on how to use SupraSeal PC2 with your lotus-worker, as well as how to use feature, please refer to the documentation.
