Therefore, the fund deal of the assets on the block chain can be directly completed by using the fund outside the chain, and the fund risk brought by introducing a third-party platform is avoided.
For example, referring to fig. 2, fig. 2 is a flowchart of a specific legal digital currency based block-chain asset deal method disclosed in an embodiment of the present application.
User a needs to buy asset X on the blockchain belonging to user B, and the flow based on legal digital currency is as follows:
a) a user A generates a random number s, and calculates a hash value H(s) by using an agreed abstract algorithm H; generating a timeout time T1;
b) a user A initiates an asset ownership transfer application on the blockchain to the blockchain, and writes H(s) and the overtime T1 into a blockchain account book as parameters, and the transaction state is modified to be confirmed;
c) after finding the application, the user B confirms that the ownership transfer is agreed, and initiates operation to the block chain, and the block chain modifies the transaction state into a state of waiting for payment;
d) and (3) the user A inquires that the transaction state is to be paid, and sends the H(s) and the timeout time T2(T2> T1) generated in the step a) to the digital currency operator A 'opened by the user A, and the A' generates a digital currency string locked by the hash time.
Where a programmable portion of the hash time locked digital currency note string, index digital currency note string D, is written to a validation logic, the lock is released if and only if s ' is entered such that H (s ') ═ H(s) and the current time T ' < ═ T2, otherwise the note string is not available.
A ' initiates a cross-bank transfer or a peer transfer to B's digital monetary account open at B ', where A ' may be equal to B '.
e) And the user B receives the transfer, and the digital currency in the account B is in a locked state and cannot be used. B verifies that H(s) in the digital currency is consistent with the block chain, verifies that T2> T1, and T2-T1 are sufficient to complete the digital currency unlocking operation;
f) the user B initiates an unlocking application and modifies the transaction state into a state to be unlocked;
g) the user A transmits s '(s' ═ s) to the block chain, and initiates unlocking; the intelligent contract on the block chain verifies H (s ') -H(s) and the current time T' < -T1, and the verification is passed, the transaction state is modified to be paid, and the property right is modified to be A;
h) after the user B acquires the transaction state and the s ' transmitted by the user A, the user B requests the operation mechanism B ' to unlock the digital currency coin string D by using the s ';
i) user A does not initiate the unlocking operation within the time T1, and operator B 'checks that the digital currency is still in the locked state when the time is greater than T2, and automatically returns to the digital currency account opened by user A in operator A'.
For example, referring to fig. 3, fig. 3 is a diagram illustrating a status of an asset transaction on a blockchain according to an embodiment of the present disclosure.
