Hybrid centralized and decentralized enterprise system

A non-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for providing a hybrid enterprise system comprising a centralized sub-system and a decentralized sub-system, the hybrid enterprise system executing a change management system to manage documents between parties, the operations comprising:

• receiving, by the centralized sub-system, user data representing a user that is authorized to access one or more electronic documents stored in the centralized sub-system, the hybrid enterprise system being provided by an enterprise and the user is an agent of a second-party that interacts with the enterprise;
• generating a hash identifier that is unique to the user, the hash identifier being generated based on at least a portion of the user data;
• recording, by the decentralized sub-system, the hash identifier in a blockchain that is maintained within the decentralized sub-system, the blockchain being stored in multiple nodes of the decentralized sub-system;
• limiting, by the centralized sub-system, access to the electronic document in response to access of the user to the electronic document;
• receiving, by the centralized sub-system, a change to one of the electronic documents from the user, the change being associated with the hash identifier that is unique to the user;
• editing, by the centralized sub-system, the electronic document based on the change;
• storing, by the centralized sub-system, the electronic document edited based on the change to replace the electronic document stored in a central repository of the centralized sub-system;
• and
• sending, by the centralized sub-system, a change log entry of the electronic document to the decentralized sub-system to be recorded in the blockchain, the change log entry comprising the change to the electronic document and the hash identifier of the user.
