Contract apparatus and method of blockchain using location information

A blockchain type contract terminal using position information comprising:

• an input module that is inputted with a contract term regarding an object of contract;
• a position information collection module that collects, in real time, position information of the object and position information of a contract partner terminal at a time of contract;
• a contract creation module that creates a contract by using the contract term inputted by the input module and the position information of the object and the position information of the contract partner terminal at the time of contract collected in real time by the position information collection module;
• a blockchain creation module that encrypts the contract created by the contract creation module to create a blockchain;
• a blockchain distributed storage control module that transmits the blockchain created at the blockchain creation module to a first terminal in a P2P manner for storing on a network in a distributed manner;
• a query creation module that creates a query of the contract to search;
• a query transmission module that transmits the query created by the query creation module to the first terminal;
• a contract receiving module that receives the contract corresponding to the query from the first terminal;
• a contract display module that displays the contract received at the contract receiving module;
• a query receiving module that receives a query for searching a certain contract from a second terminal;
• a polling module that polls a blockchain to read the certain contract corresponding to the query received at the query receiving module;
• and
• a relay transmission module that relays the contract read from the polling module to the second terminal that issued the query,
• wherein the contract term includes both contractors of the contract, identities of the contractors, addresses of the contractors, accounts of the contractors, and content of the contract,
• wherein the position information collection module continuously tracks and collects the position information of the object of the contract,
• the blockchain creation module stores the contract in each block, user information, digital signature, the position information of the object of contract and the position information of the contract partner terminal at the time of contract, and timestamp at the time of the contract in a header of the block, and continuously stores the position information of the object after the time of the contract,
• wherein the user information includes an ID and a password of a user, the timestamp includes information on a date and time when the creation of the contract is completed and when the contract is stored, and the digital signature includes coordinate information for each pixel of a signature image of the user and history information according to an update of the timestamp,
• wherein the position information of the object of contract and the contract partner terminal are stored on the blockchain together with the contract.
