Module near_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.
• PartialState
• 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.

Type Definitions

• 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).
• StateItem
  Serialized TrieNodeWithSize
