Read the full technical breakdown on [ethresear.ch](https://ethresear.ch/t/lattice-based-signature-aggregation/22282). + +--- + +Ethereum currently uses BLS signatures, but these are vulnerable to future quantum attacks. Our recent research explores lattice-based signature aggregation using Falcon signatures and the LaBRADOR proof system. + +Key highlights: + +* **Compact proofs:** Aggregate 10,000 Falcon-512 signatures into a 74 KB proof. +* **Efficient generation:** Proofs generated in \~6 seconds on commodity hardware. +* **Verification optimization:** Current verification time (\~2.6 seconds) identified as a primary bottleneck, with active work to reduce it further. + +This work is part of our broader post-quantum initiative at PSE, focusing on securing Ethereum's core infrastructure. + +--- + +🔗 **Full technical details and discussions:** [Lattice-based signature aggregation on ethresear.ch](https://ethresear.ch/t/lattice-based-signature-aggregation/22282) +
