LVMT - An Efficient Authenticated Storage for Blockchain

Explore a 15-minute conference talk from OSDI '23 that introduces LVMT (Layer Versioned Multipoint Trie), a novel high-performance blockchain storage solution. Learn how LVMT addresses the performance bottleneck of authenticated storage access in blockchain systems by significantly reducing I/O amplifications. Discover the key features of LVMT, including its use of the authenticated multipoint evaluation tree (AMT) vector commitment protocol, multi-layer design for unlimited key-value pair support, and version number storage. Understand how LVMT outperforms the standard Merkle Patricia Trie (MPT) storage structure, delivering read and write operations six times faster and boosting blockchain system execution throughput by up to 2.7 times in real Ethereum traces. Gain insights into this efficient authenticated storage solution presented by researchers from Shanghai Tree-Graph Blockchain Research Institute, University of Toronto, and Tsinghua University.
