Embodiment Construction

[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047]The solution of the embodiment of the present invention is mainly: when the transaction transfer party initiates a transaction, first determine the transfer value of the transaction, and search for a list of objects that meet the transfer value in the wallet contract, and then call the conversion contract to verify the transaction and The object list, after the transaction and the object list are verified, write a preset field in the object list to indicate that the object has been used, and finally create a new object contract, and The attribute field in the object contract is initialized by using the transfer value and the account address of the transaction recipient to obtain the object list of the transaction recipient, thereby realizing object flow transfer. To solve the technical problems of object flow ve...

Abstract

The invention discloses a block chain object transfer method and system and a computer readable storage medium. The method comprises the following steps: when a transaction transferring party initiates a transaction, determining a transfer value of the transaction, and searching a list of object objects satisfying the transfer value in a wallet contract; invoking a conversion contract to verify the transaction and the list of objects; writing a preset field in the object list after the transaction and the object list are verified to indicate that the object has been used; newly building the object contract, and initializing the attribute field in the object contract by using the transfer value and the account number address of the transaction receiver, so as to obtain the object list of the transaction receiver, thereby realizing the object logistics transfer. The invention makes the application scene of object logistics transfer richer, and improves the simplicity of object tracing.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain object flow transfer method, system and computer-readable storage medium. Background technique [0002] The existing transaction process and the method of object flow transfer generally adopt: the ownership transfer method based on the UTXO (UnspentTransaction Outputs, unspent transaction output) model and the account model. Among them, when the object flow is transferred in the UTXO model, the backtracking of the transaction can be realized, but the transaction object and application scenario are limited to encrypted digital currency, and the ownership verification process uses limited script opcodes, lacking the programmable nature of smart contracts. support. However, the account model based on the idea of ​​a state machine, although supported by powerful functions of smart contracts, is the current state at any moment, and the implementation method...
