Abstract: Disclosed is a method for use in a transmission of a virtual asset from a sender having a sending account at a sending virtual asset service provider (sending VASP) to a recipient having a receiving account at a receiving virtual asset service provider (receiving VASP). The method involves subsequent to verification that the receiving account at the receiving VASP is valid, determining, by a verification node, if the transmission has been recorded on a blockchain network; and subsequent to determination that the transmission has been recorded on the blockchain network, sending, by the verification node to the receiving VASP, a request to update the receiving account at the receiving VASP about the transmission of the virtual asset from the sender to the recipient. In the method, the verification node does not belong to either the sending VASP or the receiving VASP.

Abstract: A method for mediating virtual asset transmission is provided. The method comprises receiving a first information on virtual asset to be transmitted from a first user to a second user from a first virtual asset service provider (VASP) server managing virtual asset of the first user, transmitting a verification request as to whether information on the second user included in the received first information is correct to a second VASP server managing virtual asset of the second user, receiving a verification result indicating that the information on the second user is correct from the second VASP server as a response to the verification request, and transmitting the received verification result to the first VASP server. The method further comprises transmitting virtual asset update request of the second user to the second VASP server if it is determined that the transaction has been recorded in the blockchain.
