1. A system for managing storage-state data and certifying ownership of by-the-barrel liquor using a public blockchain, characterized by including:
barrels to be filled with an unblended liquor,
GPS sensors and IoT sensors installed on the barrels,
a server for managing the system along with a processing program thereof, which is program code recorded on a non-transitory computer-readable medium which is connected to the server, and
an application/wallet provider configured to connect to the server over the Internet,
wherein the server is configured to receive data transmitted by each GPS sensor and each IoT sensor, operate the processing program, and connect to the public blockchain over the Internet,
wherein the processing program:
records on the server, basic data of each of the barrels including a distillery name, brand, and unblended liquor fill date, which are linked to a unique barrel number assigned to each barrel;
obtains and records on the server, location information transmitted by the GPS sensor linked to the barrel number, and storage-state data of each barrel transmitted by the IoT sensor linked to the barrel number, including time elapsed from the unblended liquor fill date, and temperature and humidity taken at each specified time interval;
hashes the basic data, location information, and storage-state data by linking each barrel number thereto, and records a result on the public blockchain; and
records on the public blockchain, a certificate token linked to each barrel number,
wherein the application/wallet provider is configured to receive all certificate tokens from the server and to provide a buyer with a certificate token of a barrel of the buyer's interest who accesses the public blockchain, as a purchase process, to obtain storage-state data and ownership data associated with the barrel number linked to the certificate token.
