METHOD AND SYSTEM FOR BUILDING FAST SYNCHRONIZABLE DECENTRALIZED DISTRIBUTED DATABASE

摘要

A method and system for configuring a decentralized distributed database using blockchain according to various embodiments relates to a method and system for configuring a decentralized distributed database managed by P2P network participants using blockchain technology, and modified By using the main chain, which is an impossible block chain, information about what kind of work needs to be done now is transparently provided to all participants, and the database status of the account along with account registration using the account chain in the form of a block chain that can be modified. is provided to all participants without leakage of personal information, users request synchronization of their data to the sidechain network without leakage of their personal information, and 'approval' required for synchronization of the entire database system using multiple sidechains It is designed to proceed with high-speed synchronization, and to configure the commands necessary for synchronization into a smart contract to proceed with synchronization. In the actual synchronization process, a local database that has completed synchronization provides data necessary for synchronization to other local databases that have not completed synchronization, thereby eliminating a bottleneck that appears when using a central database, and synchronizing accuracy of each local database We proposed a distributed database method and system that enables high-speed synchronization by allowing users to check the data using the public main chain and account chain that cannot be forged or altered.
