Abstract
The invention discloses a method for optimizing the interoperability of a distributed account book, which solves the problems of high consumption of software and hardware resources for deployment, excessively complex system and protocol and high operation cost in the existing distributed account book platform by providing the function that an intelligent contract platform of an industry opening source lacks cross-chain interoperability, and promotes enterprises to obtain due benefits by implementing the distributed account book system.
Description
Technical Field
The invention relates to the technical field of block chains, in particular to a method for optimizing distributed account book interoperability.
Background
The distributed ledger technology belongs to a distributed database technology for sharing, copying and synchronizing information among network member nodes, and the distributed ledger records transaction matters among network participating nodes, such as asset flowing or data exchange. A distributed ledger is essentially a database of assets that can be shared across multiple sites, different geographical locations, or across a network of multiple institutions. It records data transactions according to the principles of a point-to-point network protocol and enables multiple members to manage copies of their own public ledgers and synchronize simultaneously among all nodes without authorization from the lead entity.
In a distributed ledger network, participants can obtain a copy of a unique, real ledger; any changes in the ledger will be reflected in all copies. The distributed ledger technology is introduced as a new internet value layer, adding a three-in-one feature for any asset class transaction (including information, data and physical): trustworthiness, transparency, and traceability. Through the distributed account book technology, identity verification, authorization, tracking and registration can be carried out in a system for implementing peer-to-peer digital ledgers in the Internet, and meanwhile, the problems of data privacy and safety are solved.
Interoperability is defined as the ability of two or more components or systems to exchange information and utilize the exchanged information. In the technical field of distributed accounts, interoperability represents the ability of a distributed account platform to interact with other business platforms and information systems and share data. It is apparent that the shared data of these business platforms is orchestrated by introducing integration across distributed ledger platforms to manage data usage in the enterprise.
Due to the lack of uniform technical standards of the distributed ledger technology, the realization of almost every ledger technology presents unique characteristics. Different organizations or enterprises may employ different distributed ledger techniques, and the overall deployment of distributed ledger systems and digital platforms is limited in many ways. At present, various methods for solving and improving interoperability of a distributed ledger have been proposed in the industry, such as a naive relay solution, a side chain solution, a predictive teller solution, a notary solution, etc., and many of these solutions have not been practically applied, because the implementation of these solutions has the problems that the software and hardware resources required to be invested for deployment are too high, and the functions of privacy, security, ownership, governance, trust, etc. required for solution make the software system and the protocol extremely complex, and the operation cost is high after the deployment and implementation.
