Research on Node Collaborative Storage Method for Consortium Chain Ledger Data

Blockchain as a technology for solving trust issues has received increasing attention, especially for consortium chains that combine the advantages of public and private chains, which have become very popular. However, as consortium chain applications deepen, ledger data expands rapidly, and general users find it difficult to provide hardware support for such large capacity storage. This leads to fewer high-intensity nodes that can participate in maintaining the consortium chain, gradually centralizing the consortium chain ledger. At the same time, as the scale of the consortium chain expands, the requirements for the concurrency of the consortium chain are also increasing, and the storage scalability of the consortium chain has become a bottleneck for the future development of the consortium chain. This article proposes a collaborative storage method for consortium chain ledgers, which aims to address the shortcomings of traditional consortium chains in ledger storage modes.
