A Smart, Efficient and Novel Distributed Ledger Technology for Information System

Although distributed ledger technology (DLT) provides new and distinct benefits for information systems, some of its features, such as slower data processing, are incompatible with many applications. A new DLT architecture based on main-sub-ledger is presented in this paper. It achieves physical data isolation, ensuring the privacy and security of business data. Simultaneously, the main-sub-ledger creates tiered data storage, effectively relieving node data storage pressure and improving data processing capacity.
