Multi-Party Revocation in Sovrin: Performance through Distributed Trust
IACR Cryptology ePrint Archive
Accumulators provide compact representations of large sets and compact membership witnesses. Besides constant-size witnesses, publickey accumulators provide efficient updates of both the accumulator itself and the witness. However, bilinear group based accumulators come with drawbacks: they require a trusted setup and their performance is not practical for real-world applications with large sets. In this paper, we introduce multi-party public-key accumulators dubbed dynamic (threshold)dblp:journals/iacr/HelmingerKRW20a fatcat:mn22hnielbhxrdy3k2ztmwwzfq
