Talk Title:
Hash-based accumulation schemes

Abstract:
Accumulation schemes are proof systems that enable combining two or more proofs into one. Despite their simplicity they have broad and powerful applications, including recursive proofs, distributed proving and streaming provers. Previously, accumulation schemes required homomorphism and could only be built from pre-quantum assumptions. I'll be discussing a recent line of work on post-quantum accumulation schemes that are secure in the random oracle model.
