A method of verifying the destination of a transaction between nodes in a network includes receiving transaction information corresponding to a transaction between the nodes, where the transaction information comprises a unique destination identifier and a destination name and where the unique destination identifier defines a destination account of the transaction; obtaining from a storage unit a set of names used in previous transactions to that destination account; determining at least one disparity value between the destination name and the set of names; and producing a destination verification value based on the at least one disparity value, wherein the destination verification value is used to verify whether the transaction between nodes should proceed.
