Crate subspace_verification

Verification primitives for Subspace.

Structs

• PieceCheckParams
  Parameters for checking piece validity
• VerifySolutionParams
  Parameters for solution verification

Enums

• Error
  Errors encountered by the Subspace consensus primitives.

Functions

• calculate_block_weight
  Calculate weight derived from provided solution range
• check_reward_signature
  Check the reward signature validity.
• derive_next_solution_range
  Derives next solution range based on the total era slots and slot probability
• derive_pot_entropy
  Derive proof of time entropy from chunk and proof of time for injection purposes.
• is_piece_valid
  Validate witness embedded within a piece produced by archiver
• is_record_commitment_hash_valid
  Validate witness for record commitment hash produced by archiver
• is_within_solution_range
  Returns Some(solution_distance) if solution distance is within the solution range for provided parameters.
• verify_solution
  Verify whether solution is valid, returns solution distance that is <= solution_range/2 on success.
