This presentation by Philipp Muens explores how hash-based signature schemes can be extended to support multiple signatures and why they're critical for Ethereum's post-quantum security roadmap, particularly for the proposed Beam Chain.
What You'll Learn:
How to extend one-time signature schemes to many-time signatures
The eXtended Merkle Signature Scheme (XMSS)
Practical application of hash-based signatures in Ethereum's consensus
Trade-offs between signature size and computational cost
Parameter selection for real-world deployment
Key Topics:
Quick recap of Winternitz One-Time Signatures (Winternitz-OTS)
Target Sum Winternitz-OTS optimization
Merkle Tree construction for multiple signatures
Slot-based synchronization mechanism
Post-quantum SNARK aggregation
Hash function selection: SHA-3 vs Poseidon 2
Performance analysis and parameter recommendations
