Chord Ring Distributed Storage Method for Ethereum Data

Abstract

To address the limitations of blockchain data storage capacity and uneven dis-tribution, this paper proposes a Chord dual-ring distributed storage method based on virtual nodes. Building upon the original Chord protocol, this approach introduces virtual rings to construct a “storage ring-virtual ring” dual-ring structure. Target virtual nodes are located through routing table lookups, and data is distributed across the storage ring via a name mapping mechanism. Sim-ulation experiments validate the proposed scheme's effectiveness by evaluating load balancing and query success rate across varying sharding granularities. Results demonstrate that this approach not only efficiently achieves sharded storage for blockchain data but also ensures balanced distribution of block data.
