Expand description

First step in sector sealing process. Called before seal_pre_commit_phase2. Reads unsealed data from in_path, generates sealed data and writes to out_path.

§Arguments

  • registered_proof - Seal proof to generate.
  • cache_path - Directory path to use for generation of Merkle tree on disk.
  • in_path - File path of the input sector file to perform the seal operation on.
  • out_path - File path to write the resultant sealed sector to.
  • prover_id - Unique ID of the storage provider.
  • sector_id - ID of the sector, usually relative to the miner.
  • ticket - The ticket used to generate this sector’s replica-id. For Filecoin this randomness drawn from the Filecoin blockchain’s verifiable random function (VRF), which generates tickets with each new block.
  • piece_infos - The piece info (commitment and byte length) for each piece in the sector.

Returns Merkle tree labels and commitment for use by seal_pre_commit_phase2.
