Struct diem_types::proof::definition::AccumulatorConsistencyProof[−][src]

pub struct AccumulatorConsistencyProof { /* fields omitted */ }
Expand description

A proof that can be used to show that two Merkle accumulators are consistent – the big one can be obtained by appending certain leaves to the small one. For example, at some point in time a client knows that the root hash of the ledger at version 10 is old_root (it could be a waypoint). If a server wants to prove that the new ledger at version N is derived from the old ledger the client knows, it can show the subtrees that represent all the new leaves. If the client can verify that it can indeed obtain the new root hash by appending these new leaves, it can be convinced that the two accumulators are consistent.

See [crate::proof::accumulator::Accumulator::append_subtrees] for more details.
