PoolMetadata

scalus.cardano.ledger.PoolMetadata

case class PoolMetadata(url: String, metadataHash: ByteString)

Represents metadata for a stake pool in the Cardano blockchain.

Pool metadata provides information about the pool such as name, description, ticker symbol, etc. It's stored off-chain, and only the URL and hash are included in the blockchain.

Value parameters

metadataHash: Hash of the metadata for verification. Conventionally a 32-byte Blake2b-256 digest, but the ledger does not constrain it: the CDDL says pool_metadata = [url, bytes] (conway.cddl:494, unchanged since Allegra) and Haskell holds it as pmHash :: !ByteArray with a decoder that checks no length (State/StakePool.hs:293-296, :522-524). Hence a plain ByteString rather than a fixed-width MetadataHash.
url: URL where the metadata can be found
