Dynamic Positive and Universal accumulators according to the paper: Dynamic Universal Accumulator with Batch Update over Bilinear Groups Provides
- a dynamic positive accumulator
PositiveAccumulator, that supports membership proofs. - a dynamic universal accumulator
UniversalAccumulator, that supports membership and non-membership proofs. - a zero knowledge proof of membership and non-membership in the accumulators with
ProofProtocol.
Allows
- single and batch updates (additions, removals or both) to the accumulators.
- single and batch updates to the witness.
Both accumulators implement that trait Accumulator that contains the common functionality.
Both MembershipWitness and NonMembershipWitness can be updated either using secret key or using public
info published by accumulator manager called Omega.
Most of the update logic is in the trait Witness which is implemented by both MembershipWitness
and NonMembershipWitness.
The implementation tries to use the same variable names as the paper and thus violate Rust's naming conventions at places.
