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.　©　2023　IEEE.
