Title:
BLOCK CHAIN SYSTEM, BLOCK CHAIN MANAGEMENT DEVICE, NETWORK CONTROL DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/003386
Kind Code:
A1
Abstract:
The present invention improves the confidentiality of data flowing through a block chain and reduces a risk of leakage of data. This block chain system includes: computer resources that can operate as calculation nodes of logical block chains which have been logically divided; a block chain management device that manages the logical block chains respectively comprising the calculation nodes; and a network control device that controls a network where the calculation resources are allocated such that, regarding the plurality of block chains, communication between calculation nodes that belong to the same logical block chain is permitted, whereas communication between calculation nodes that belong to different logical block chains are inhibited.
