a16z crypto's Aerie aggregates 32,768 post-quantum signatures in 0.65 seconds
- —Aerie aggregates over 50,000 Falcon-512 signatures per second without GPU acceleration
- —Proof verification takes 54 ms on a single core, about 10x faster than checking signatures individually
- —The proof is about 66 KiB, but per-signature salts push total data to roughly 42 bytes per signature
- —Post-quantum signatures are 10–100x larger than elliptic-curve ones, raising block and node costs
Why it matters: If aggregation scales, Ethereum and other proof-of-stake chains could adopt post-quantum signatures without a sharp jump in block size and node operating costs.
