In cryptography, an accumulator is a one way membership hash function. It allows users to certify that potential candidates are a member of a certain set without revealing the individual members of the set. This concept was formally introduced by Josh Benaloh and Michael de Mare in 1993. See more There are several formal definitions which have been proposed in the literature. This section lists them by proposer, in roughly chronological order.
