Claim 0:
1. A computer-implemented method for verifying physical proximity of counterparties in digital asset transfers, the method comprising:
receiving, by a sender device, a recipient hash and a recipient wallet address communicated from a recipient device, the recipient hash and the recipient wallet address being associated with the recipient device, wherein the recipient device, is configured to generate the recipient hash with a hash function based on each of the recipient wallet address and a first set of location coordinates that corresponds to a recipient device physical location;
receiving, by the sender device, a set of signals at a sender device physical location;
detecting, by the sender device, a second set of location coordinates based on the set of signals, the second set of location coordinates corresponding to the sender device physical location;
generating, by the sender device, a hash value with the hash function based on the recipient wallet address and the second set of location coordinates;
verifying, by the sender device, that the recipient device and the sender device have same location coordinates based on a determination that the hash value corresponds to the recipient hash received from the recipient device; and
transferring, by the sender device, a digital token from a sender wallet address associated with the sender device to the recipient wallet address based on the determination that the hash value corresponds to the recipient hash,
wherein the step of transferring the digital token from the sender wallet address to the recipient wallet address further includes generating a request to transfer the digital token to the recipient wallet address, the request including a digital signature of the sender device, wherein the request is communicated to and authenticated by a distributed ledger network based on the digital signature, and the digital token is transferred based further on the authenticated digital signature.
