Abstract
A method for conducting an offline data exchange associated with a blockchain includes: storing a structured data set associated with a blockchain network, the data set including a network identifier, unspent output hash, output index, output value, and key pair; receiving the network identifier and a transaction amount from a point of sale; validating the structured data set as including the network identifier and an output value greater than or equal to the transaction amount; transmitting the unspent output hash and output index to the point of sale; receiving a destination address from the point of sale; generating transaction data including the destination address and a payment amount based on the transaction amount; and transmitting the transaction data to the point of sale.
