Structs

• LAYERS
• POREP_PARTITIONS
• WINDOW_POST_SECTOR_COUNT

Constants

• DRG_DEGREE
  The base degree used for all DRG graphs. One degree from this value is used to ensure that a given node always has its immediate predecessor as a parent, thus ensuring unique topological ordering of the graph nodes.
• EXP_DEGREE
  The expansion degree used for Stacked Graphs.
• FIP92_MAX_NI_POREP_AGGREGATION_PROOFS
• FIP92_MIN_NI_POREP_AGGREGATION_PROOFS
  Constant NI-PoRep aggregation bounds specified in FIP-0090, but superseded by FIP-0092
• MAX_LEGACY_REGISTERED_SEAL_PROOF_ID
• MINIMUM_RESERVED_BYTES_FOR_PIECE_IN_FULLY_ALIGNED_SECTOR
• MINIMUM_RESERVED_LEAVES_FOR_PIECE_IN_SECTOR
• MIN_PIECE_SIZE
  The minimum size a single piece must have before padding.
• PUBLISHED_SECTOR_SIZES
  Sector sizes for which parameters have been published.
• SECTOR_SIZE_1_GIB
• SECTOR_SIZE_2_KIB
• SECTOR_SIZE_4_KIB
• SECTOR_SIZE_8_MIB
• SECTOR_SIZE_16_KIB
• SECTOR_SIZE_16_MIB
• SECTOR_SIZE_32_GIB
• SECTOR_SIZE_32_KIB
• SECTOR_SIZE_64_GIB
• SECTOR_SIZE_512_MIB
• SINGLE_PARTITION_PROOF_LEN
  The size of a single snark proof.
• SUPPORTED_SECTOR_SIZES
  Sector sizes for which parameters are supported.
• TEST_SEED
• WINDOW_POST_CHALLENGE_COUNT
• WINNING_POST_CHALLENGE_COUNT
• WINNING_POST_SECTOR_COUNT

Functions

• get_porep_non_interactive_partitions
  Returns the number of partitions for non-interactive PoRep for a certain sector size.
• is_sector_shape_base
• is_sector_shape_sub2
• is_sector_shape_sub8
• is_sector_shape_top2

Type Aliases

• DefaultBinaryTree
  A binary merkle tree with Poseidon hashing, where all levels have arity 2. It’s fully persisted to disk.
• DefaultOctLCTree
  A merkle tree with Poseidon hashing, where all levels have arity 8. Some levels are not persisted to disk, but only cached in memory.
• DefaultOctTree
  A merkle tree with Poseidon hashing, where all levels have arity 8. It’s fully persisted to disk.
• DefaultPieceDomain
