Abstract:
A blockchain-based method includes: receiving, by a smart label via accessing a block of a blockchain stored on a computer system, a cold chain requirement for a product, wherein the smart label is affixed to a package containing the product, the cold chain requirement for the product is specified and stored by a manufacturer of the product in the block of the blockchain; storing, by the smart label, the cold chain requirement in a memory of the smart label; receiving, by the smart label, from a temperature sensor a temperature of the product, wherein the temperature sensor is affixed to the package containing the product; comparing, by the smart label, the temperature of the product with a temperature range of the product specified in the cold chain requirement; and adding, by the smart label, the temperature of the product and a time at which the temperature of the product is received by the smart label, to the blockchain, if the temperature of the product is outside of the temperature range specified in the cold chain requirement.
