Method for sharing business information based on mutual confirmation blockchain

A method for sharing business information based on a mutual confirmation blockchain in which a plurality of certified terminals are connected to each other through a network, wherein each of the plurality of the certified terminal includes an application unit for operating thereof as a node of a blockchain, and wherein business information registered in the blockchain is shared among the plurality of the certified terminals, the method comprising steps of:

• registering, by an application unit of a specific node, approver information, wherein the approver information corresponds to an approver of the business information to be shared;
• transmitting, by the application unit of the specific node, request information for requesting confirmation of the business information registered in the blockchain to the approver node corresponding to the approver;
• confirming, by an application unit of the approver node, validity of the request information, and registering certification information and the business information in the blockchain when the validity is confirmed;
• confirming, by the application unit of each of the nodes of the blockchain, validity of the certification information such that a validity in a preset shared ledger is registered when the confirmation is successful;
• generating and storing, by the application units of the specific node and the approver node, compensation information according to the registration of the certification information of the approver;
• and
• storing, by the application unit of the specific node and when the business information requires fast processing, a registration-related transaction of the business information in a predetermined temporary storage space as temporary valid information, and requesting each of the nodes belonging to the blockchain to store the temporary valid information in the predetermined temporary storage space such that the registration-related transaction of the business information corresponding to the temporary valid information stored in the temporary storage space is searched when searching the shared ledger,
• subtracting, by the application unit of the specific node, a predetermined setting amount of a holding amount cumulatively stored according to the compensation information in the electronic wallet of the specific node corresponding to the business information requiring the fast processing and generating the request information including paid information that promises to pay the setting amount to the approver of the approver node upon fast processing of the business information to transmit the generated request information to the approver node,
• wherein the generating and storing the compensation information step further provides the business information of the specific node and registers the valid business information in the blockchain through mutual confirmation,
• wherein the business information further includes the approver information, and
• wherein a contract condition that a penalty is received when the confirmation of the approver is failed in the business information corresponding to the temporary valid information.
