Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for digital asset transfer. One of the methods includes: obtaining a request for transferring a quantity of a digital asset from a first blockchain account associated with a blockchain to a second blockchain account associated with the blockchain, wherein the request identifies a tangible asset corresponding to the digital asset; determining a blockchain contract that is deployed on the blockchain and that corresponds to the tangible asset identified in the request; generating, based on the obtained request, a blockchain transaction for transferring the quantity of the digital asset from the first blockchain account to the second blockchain account, wherein the blockchain transaction invokes the determined blockchain contract; and sending the generated blockchain transaction to a blockchain node for adding to the blockchain.
