This Week in Lotus - Week 19 - 2023

Posted May 12, 2023 by  ‐ 2 min read

🆕 Lotus v1.23.1-rc2

The second release candidate for v1.23.1 was released this week. It includes a couple of backports, most notably:

  • A fix that addresses the regression where using the GET_<sectorSize>_MAX_CONCURRENT environment variable could lead to a stuck scheduler.
  • We now hidden the legacy lotus-miner market functions from the CLI. Your lotus-miner cmd output should now be a lot cleaner.

❗ Note that this release candidate disables the legacy markets subsystem in the Lotus-Miner by default. We recommend all our users to use Boost for markets related operations.

🆙 nv20 reminder

Gentle reminder that the nv20 upgrade is happening next week 2023-05-18T13:00:00Z. After which the old windowPoSt proofs (v1) will no longer be accepted by the network.

For SP-users that has upgraded to Lotus v1.22.1 or Lotus v1.23.x releases there is nothing that you need to do, as you already have been generating and using the new windowPoSt-proofs (v1_1) since after the nv19 upgrade.

If you want to double check that everything is okay, either:

  • Pick a proving deadline with a small amount of sectors and run lotus-miner proving compute windowed-post [Deadline]. And check that the “PoStProof”: output is either 13 for 32GiB sectors or 14 for 64GiB sectors.
  • Check your windowPoSt messages in any explorer and see that the “PoStProof” type in the parameters is either 13 for 32GiB sectors or 14 for 64GiB sectors.

After the upgrade the lotus state network-version command will show: Network Version: 20

That’s it for the week! Have a great weekend! ☀️
