We are pleased to announce our new research paper “Fractional Verkle Trees for Scalable Post-Quantum Signatures”, authored by Maksim Iavich, Tamari Kuchukhidze and Razvan Bocu, has been officially published.
The paper introduces a novel Fractional Verkle Tree (FVT) construction that significantly reduces signature size and verification costs compared to traditional Merkle-based schemes, making it highly effective for IoT, blockchain, and other bandwidth-limited applications.
