Claim 2:
3. A computer system for automatically for digitally tracking ownership of goods with a blockchain comprising:
a processor;
a memory containing instructions when executed on the processor, causes the processor to perform operations that:
provide the blockchain, wherein the blockchain comprises a set of blockchain ownership records provided in a chronological mathematical proof format such that specified data exists in a specific chronological order;
save a smart contract that references a real-world object in the blockchain, wherein the smart contract comprises a tool for tracking ownership of the real-world object, wherein the smart contract comprises a real-world object identifier, and an address data, wherein the smart contract comprises a real-world object holder data, real-world object name data, and a real-world object location data, wherein the smart contract comprises a real-world object description data, wherein the real-world object identifier is a hash of a specified media file, and wherein the hash of a specified media file comprises a hash of at least one specified digital photograph of the real-world object that is being tracked in the blockchain, and wherein the blockchain uses a private and public keypair address comprising a private key and a public key to enable a modification of the smart contract and wherein any new values of the real-world object that is being tracked in the blockchain are updated as a string in the smart contract storage on the blockchain;
with a computer application:
enable an owner of the real-world object to modify an owner data portion of the smart contract to a new owner entity to change the ownership of the real-world object in the blockchain, wherein the owner is defined as a holder of the private key, wherein only the owner holding the private key is allowed to change a property in the smart contract, wherein the property of the smart contract comprises an ownership of the real-world object, and wherein the tracking of the ownership of the real-world object is saved in the smart contract in the blockchain;
update the owner data portion of the smart contract in the blockchain to include the new owner entity;
generating a matrix code that enables access to the owner data portion of the smart contract a user who scans the matrix code with a user-side mobile device,
wherein the unique ID code comprises a QR code, and wherein the QR code address corresponds to the user's blockchain public key and database identity in the system that is a supplementary data in a traditional database, and
wherein a user scans the QR code to fetch history information about the item, wherein the history of the item is fetched in the application, and wherein the history information comprises an ownership history, a plurality of details about the item, and an ability to contact the owner of the item.
