Class BlockHashFilter
Predicate filter on the block.hash query parameter of the
contract-results endpoints (/api/v1/contracts/results,
/api/v1/contracts/{id}/results). Scopes the returned results
to a single block by its hash.

Syntax
public sealed class BlockHashFilter : IMirrorFilter, IMirrorQueryParameterRemarks
The wire format accepts either a 32-byte Ethereum block hash (64 hex chars) or a 48-byte Hedera SHA-384 block hash (96 hex chars). Use Is(EvmHash) when you already have an EvmHash; use Is(ReadOnlyMemory<byte>) for raw bytes (EVM 32-byte or Hedera 48-byte). Construct via the static factories; the ctor is private.
