Type Definition dock_runtime::accumulator::AccumulatorKeys

pub type AccumulatorKeys<T> = StorageDoubleMap<_GeneratedPrefixForStorageAccumulatorKeys<T>, Blake2_128Concat, AccumulatorOwner, Identity, IncId, AccumulatorPublicKey<T>, OptionQuery, GetDefault, GetDefault>;

Public key storage is kept separate from accumulator storage and a single key can be used to manage several accumulators. It is assumed that whoever (DID) owns the public key, owns the accumulator as well and only that DID can update accumulator.
