Abstract

The invention relates to a multi-domain blockchain network with data flow control. An example operation may include one or more of receiving an endorsed storage event from a first security domain thatconforms to a first security policy and that is isolated from a second security domain that conforms to a second security policy which is different than the first security policy, determining that the storage event satisfies a cross-domain security policy based on the first and second security policies, creating a cross-domain data block which stores the storage event that satisfies the cross-domain security policy as a blockchain transaction, and transmitting the cross-domain data block to a first blockchain node included in the first security domain and a second blockchain node included inthe second security domain.

Description

technical field [0001] The present application relates generally to a system for storing data via a blockchain, and more specifically, to a system that can control bi-directional data flow between physically isolated security domains via a single logical blockchain network blockchain network. Background technique [0002] A security domain (also referred to herein as a domain) may be a domain within which behavior, interaction, and results occur, and is defined by an administrative security policy. For example, a security domain can be defined by rules for users, processes, systems, and services that apply to activities within the domain and to activities with similar entities within the domain. Networks with different security domains can be kept separate from other networks. These networks may contain confidential information that is only available to authorized users, or otherwise store information that you do not wish to share with users of other networks. [0003] A ...
