摘要： The described technology relates to a deep learning based method and system for detecting abnormal cryptocurrency transaction between computing devices in a blockchain network. In once aspect, the method includes generating, at a server, a first data set, a second data set, and a third data set from the transactions of a user wallet address with at least one other user wallet address. The method may also include running a pre-learned deep learning module to extract a first feature vector, a second feature vector, and a third feature vector from the first data set, the second data set, and the third data set. The method may further include converting the first feature vector, the second feature vector, and the third feature vector into an intermediate value and comparing the intermediate value to a predetermined reference value to determine if a fraudulent transaction associated with the user wallet address has occurred.

摘要： Disclosed is a method for use in a virtual asset transmission 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 sending, to the receiving VASP, a first request for verifying the receiving account of the recipient at the receiving VASP; receiving, from the receiving VASP, a verification result confirming that the receiving account of the recipient at the receiving VASP is valid; subsequently receiving, from the sending VASP, a second request for verifying a blockchain record for a transmission of a virtual asset from the sender to the recipient; upon receipt of the second request, determining if the transmission has been recorded on a blockchain network; and upon determining that the transmission has been recorded on the blockchain network, sending, to the receiving VASP, a third request to update the receiving account of the recipient at the receiving VASP about the transmission of the virtual asset from the sender to the recipient.

摘要： Provided is an electronic device including a communication interface, one or more memories, and one or more processors configured to receive, from a user terminal of a user, a rental request for a digital asset corresponding to a first token, and to perform a procedure of generating a second token based on the rental request. The first token is generated based on a first smart contract configured to prove ownership of the digital asset, and first metadata of the first token indicates an owner having the ownership of the digital asset. The second token is generated based on a second smart contract configured to prove a right of use of the digital asset, and second metadata of the second token indicates a person having the right of use of the digital asset. Generation information of the second token indicating a rental history of the digital asset is recorded in the first metadata of the first token.
