LayerZero Aerie Speeds Up Post-Quantum Signature Verification

LayerZero Labs’ Aerie research system aggregates large batches of post-quantum signatures into a single proof, offering a potential way to reduce blockchain validator workloads. On an Apple M4 Max laptop, Aerie aggregated 32,768 Falcon-512 signatures in 0.65 seconds using 16 CPU threads and no GPU; it also processed 16,384 Falcon-1024 signatures in 0.63 seconds. The Falcon-512 test used 2.1 GiB of peak memory. Aerie’s paper reports that verifying the Falcon-512 aggregate took 54 milliseconds on one core, versus 519 milliseconds to check the signatures individually. The standard aggregate was 1,346 KiB, including signature salts and headers, while the proof itself was about 66 KiB. This clarifies that the proof size is not the same as the full aggregate data. A smaller shared-salt format requires additional signing-policy and security conditions. The system uses Akita and creates one proof for the batch rather than recursively generating proofs. Earlier reported comparisons with Orthus described faster proving and verification and smaller proofs, but results depend on the systems and measurements being compared. Aerie’s benchmark results are not directly comparable with every competing system: the paper found faster proof generation than leanVM in its tests, while leanVM verified proofs faster, and the systems used different signature schemes and workloads. Falcon is still undergoing NIST standardization; ML-DSA and SLH-DSA are finalized standards. LayerZero says Aerie also supports ML-DSA aggregation, but has not released detailed performance figures. The research may help make post-quantum cryptography more practical for blockchain validators, but it is not a deployed product and does not signal an immediate change to LayerZero or Ethereum. For traders, its relevance is primarily a longer-term infrastructure and security development, not a direct short-term price catalyst.
