Expand description
A unique descriptor of the candidate receipt.
Fields§
§para_id: Id
The ID of the para this is a candidate for.
relay_parent: H
The hash of the relay-chain block this is executed in the context of.
collator: CollatorId
The collator’s sr25519 public key.
persisted_validation_data_hash: Hash
The blake2-256 hash of the persisted validation data. This is extra data derived from relay-chain state which may vary based on bitfields included before the candidate. Thus it cannot be derived entirely from the relay-parent.
pov_hash: Hash
The blake2-256 hash of the PoV.
erasure_root: Hash
The root of a block’s erasure encoding Merkle tree.
signature: CollatorSignature
Signature on blake2-256 of components of this receipt:
The parachain index, the relay parent, the validation data hash, and the pov_hash
.
para_head: Hash
Hash of the para header that is being generated by this candidate.
validation_code_hash: ValidationCodeHash
The blake2-256 hash of the validation code bytes.
