    proof_type: RegisteredPoStProof,
    randomness: &ChallengeSeed,
    sector_set_len: u64,
    prover_id: ProverId,
) -> Result<Vec<u64>>
Expand description

Given some randomness and the length of available sectors, generates a sector challenge.

The returned values are indices in the range of 0..sector_set_len, requiring the caller to match the index to the correct sector.

§Arguments

  • proof_type - PoSt proof type for this challenge, must be “winning” proof type.
  • randomness - Random value generated by caller (verifier).
  • sector_set_len - Number of available sectors to challenge.
  • prover_id - Unique 32 byte ID of prover which will be challenged with these sectors.

Returns a vector, with each element representing a sector to challenge.
