Chipmunk Aggregates 8192 Signatures Into Under 200 KB

Chipmunk, a lattice-based multi-signature scheme, aggregates 8192 signatures into under 200 KB at 112-bit security. Signatures are 5× smaller than Fleischhacker, Simkin, Zhang (CCS 2022). Non-interactive aggregation, secure against rogue-key attacks, and plausibly quantum-safe via short integer solution hardness. Full implementation and benchmarks provided.
