Abstract
A distributed hash tree-based authentication system for digital input records has more than one upper-level core node, each of which receives at least one uppermost value from aggregators. Communicating with each other about which aggregator values they have received, the nodes try to reach agreement as to which of these values should be included in duplicated current intra-node hash tree evaluations so as to form a consistent top-level value used as the basis for digital signatures associated with the digital input records.
