FROST/ROAST Signing Performance
Confidence Score
85%Current Thesis
Arch's FROST/ROAST threshold signing achieves sub-100ms signing for 300ms block times with 50-100 validators. Performance scales linearly. This enables institutional-grade security (threshold signatures) without sacrificing finality or latency.
Evolution of Belief
Threshold signing introduces unacceptable latency overhead.
Reason: Initial architecture review
FROST/ROAST achieves <100ms signing; fits comfortably in 300ms block time
Reason: Mainnet testnet results with 75-validator set

Open Questions
- •Will signing latency remain sub-100ms with 500+ validators?
- •Can we implement threshold signature recovery for >50% faults?
