A method for transferring assets, the method comprising: detecting an asset transfer request related to a blockchain member, wherein the asset transfer request involves transferring a first asset of a first asset type to a second asset of a second asset type that is to be held by the blockchain member when the asset transfer request is allowed, and the first asset to be transferred is issued by a specified anchor in a blockchain and the second asset is to be issued by the specified anchor in the blockchain; determining whether there is a first maximum trusted asset limit that is configured by the blockchain member for the specified anchor and corresponds to the first asset type and a second maximum trusted asset limit that is configured by the blockchain member for the specified anchor and corresponds to the second asset type; determining a first amount of the first asset to be transferred that is indicated by the asset transfer request and is of the first asset type, a second amount of the second asset type by converting the first amount of the first asset of the first asset type according to a conversion ratio between the first asset type and the second asset type, and a third amount of assets of the second asset type that is held by the blockchain member and that is issued by the specified anchor; and setting the second maximum trusted asset limit for the second asset type at the specified anchor in the blockchain member; allowing the asset transfer request to be applied to an asset transfer implementation when a sum of the third amount and the second amount is not greater than the second maximum trusted asset limit for the second asset type. detecting an asset transfer request related to a blockchain member, wherein the asset transfer request involves transferring a first asset of a first asset type to a second asset of a second asset type that is to be held by the blockchain member when the asset transfer request is allowed, and the first asset to be transferred is issued by a specified anchor in a blockchain and the second asset is to be issued by the specified anchor in the blockchain; determining whether there is a first maximum trusted asset limit that is configured by the blockchain member for the specified anchor and corresponds to the first asset type and a second maximum trusted asset limit that is configured by the blockchain member for the specified anchor and corresponds to the second asset type; determining a first amount of the first asset to be transferred that is indicated by the asset transfer request and is of the first asset type, a second amount of the second asset type by converting the first amount of the first asset of the first asset type according to a conversion ratio between the first asset type and the second asset type, and a third amount of assets of the second asset type that is held by the blockchain member and that is issued by the specified anchor; and setting the second maximum trusted asset limit for the second asset type at the specified anchor in the blockchain member; allowing the asset transfer request to be applied to an asset transfer implementation when a sum of the third amount and the second amount is not greater than the second maximum trusted asset limit for the second asset type.
