Module unc_primitives::challenge

Structs

• BlockDoubleSign
  Double signed block.
• Challenge
• ChunkProofs
  Invalid chunk (body of the chunk doesn’t match proofs or invalid encoding).
• ChunkState
  Doesn’t match post-{state root, outgoing receipts, gas used, etc} results after applying previous chunk.
• SlashedValidator

Enums

• ChallengeBody
• MaybeEncodedShardChunk
  Either EncodedShardChunk or ShardChunk. Used for ChunkProofs. Decoded is used to avoid re-encoding an already decoded chunk to construct a challenge. Encoded is still needed in case a challenge challenges an invalid encoded chunk that can’t be decoded.
• PartialState
  TODO (#8984): consider supporting format containing trie values only for state part boundaries and storing state items for state part range.

Type Aliases

• Challenges
• ChallengesResult
  Result of checking challenge, contains which accounts to slash. If challenge is invalid this is sender, otherwise author of chunk (and possibly other participants that signed invalid blocks).
• TrieValue
  Serialized TrieNodeWithSize or state value.
