Round 2 / Storage Onboarding R&D

The Storage Onboarding R&D project benefits Storage Providers (SPs) by streamlining and reducing costs in the onboarding pipeline, helping them operate more efficiently and economically.

Our project tackles key issues such as memory inefficiency during PoRep, limited flexibility for SPs, and the lack of a viable Sealing-as-a-Service model. In particular,

• Synthetic PoRep:
  • Reduced the size of the temporary data stored between PreCommit and ProveCommit (150 epochs) from ~400GiB to ~25GiB, with no impact on security.
• NI-PoRep:
  • Simplified storage onboarding pipeline (no precommit step, no waiting time, no precommit deposit);
  • Trustless separation between storage and computing: the proving tasks associated with sector onboarding can be outsourced;
  • Unblocking SupraSeal's full potential.
• Removal of PreCommitSectors:
  • Reduced block cron time by 10x;
  • Fixed the impossible-to-estimate-gas-beforehand-for-Provecommit problem: https://github.com/filecoin-project/specs-actors/issues/1319, https://github.com/filecoin-project/lotus/issues/7002 ;
  • Provided a simpler interface for SPs (only one method to use proveCommitSectors3);
  • Provided a simpler system for developers to understand.
