Method for mediating virtual asset transmission

A method for use in a virtual asset transmission from a first account of a first user at a first virtual asset service provider (VASP) to a second account of a second user at a second virtual asset service provider (VASP), the method comprising:

• receiving, by a verification node comprising a computing device connected to a computer communication network comprising a blockchain network, information about the second user which comprises an account number of the second account at the second VASP;
• sending, by the verification node to the second VASP, a first request for verifying the information about the second user to cause the second VASP to process verification of the information about the second user;
• receiving, by the verification node from the second VASP, an electronic verification result confirming that the information about the second user is valid;
• subsequently receiving, by the verification node from the first VASP, a second request for verifying a blockchain record for a transmission of a virtual asset from the first user to the second user, wherein the second request for verifying the blockchain record comprises transaction information associated with the transmission;
• upon receipt of the second request for verifying a blockchain record, determining, by the verification node, if the transmission has been recorded on the blockchain network, wherein determining uses at least part of the transaction information received from the first VASP;
• and
• upon determining that the transmission has been recorded on the blockchain network, sending, by the verification node to the second VASP, a third request to update the second account of the second user at the second VASP about the transmission of the virtual asset from the first user to the second user,
• wherein the verification node does not belong to either the first VASP or the second VASP.
