Method and system for enabling traceable privacy-maintaining multi-hop offline transactions in digital currencies

A method for processing offline cryptocurrency transfers, comprising:

• storing, in a computing device, a blockchain wallet having access to an amount of cryptographic currency on a blockchain associated with a blockchain network;
• storing, in a secure element of the computing device, a first public key of a first key pair;
• communicating, by the computing device, with a blockchain node in the blockchain network, to request a cryptographically signed issuing transfer message;
• receiving, by a receiver of the computing device, from the blockchain node in the blockchain network, a first transfer message that is cryptographically signed by the blockchain node using a first private key of the first key pair and is associated with a transfer of cryptographic currency to the computing device that has already been published to the blockchain associated with the blockchain network;
• validating, by a processor of the computing device, the cryptographic signature of the first transfer message using the first public key of the first key pair stored in the secure element of the computing device, wherein said validation ensures that the transfer message will be honored by the blockchain network after an offline transaction is made;
• storing, in a memory of the computing device, the validated first transfer message;
• receiving, by an input device of the computing device, a transfer instruction, the transfer instruction including at least a communication address;
• generating, by the processor of the computing device, a data container by wrapping the first validated first transfer message with a second transfer message;
• and
• electronically transmitting, by a transmitter of the computing device, the data container to an external device based on at least the communication address.
