LayerZero’s Aerie tackles the post-quantum signature bloat problem

A new aggregation system from LayerZero Labs and academic partners compresses Falcon signatures into compact proofs on an ordinary laptop Post-quantum signatures have a weight problem. They typically run 10 to 100 times larger than the classical signatures that blockchains rely on today. On October 16, 2026, LayerZero Labs unveiled Aerie, a system built to put those signatures on a diet. The research was developed with a16z crypto research, Carnegie Mellon University, and Imperial College London. Aerie is a signature aggregation system that combines large batches of Falcon signatures, which NIST has standardized as FN-DSA, into a single compact proof. Under the hood, it relies on a lattice-based polynomial commitment scheme called Akita. The headline benchmarks are notable.
