Problems solved by technology

[0005] At present, the release code of each smart contract needs to be written separately. If the smart contract is updated, the previously written release code needs to be rewritten, and the dependencies between the smart contracts need to be rearranged, which is time-consuming and labor-intensive.

specific Embodiment 2

[0115] The second specific embodiment is the release process after the smart contract is updated, the steps are as follows Figure 5 shown, including:

[0116] Step S501: Receive a smart contract change request.

[0117] Step S502: Obtain the corresponding dependency tree according to the smart contract change request, and update the nodes in the dependency tree.

[0118] Step S503: Publish the smart contract corresponding to the leaf node of the dependency tree.

[0119] Step S504: Remove the leaf node whose smart contract is successfully released from the dependency tree.

[0120] Step S505: Determine whether there is only the root node in the dependency tree, if yes, execute step S506, otherwise execute step S503.

[0121] Step S506: Publish the smart contract corresponding to the root node, and save the root node.

[0122] The embodiment of the present invention also provides a device for issuing smart contracts in the block chain, such as Figure 6 shown, including: ...

Abstract

The embodiment of the invention relates to the field of finance of science (Fintech), in particular to a method and device for issuing a smart contract in a block chain, which is used for improving the issuing efficiency and accuracy of the smart contract. The method comprises the steps of obtaining the to-be-issued smart contracts; traversing the to-be-issued smart contracts, and determining a dependency relationship between the to-be-issued smart contracts; according to the dependency relationship, establishing N dependency trees, wherein one node of each dependency tree corresponds to one smart contract, and n >= 1; and for any dependency tree, starting from the leaf node of the dependency tree to the root node of the dependency tree, issuing the smart contract corresponding to each node in sequence.

Description

technical field [0001] The invention relates to the field of technology finance (Fintech), in particular to a method and device for issuing smart contracts in a block chain. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field. The traditional financial industry is gradually transforming into Finteh, and Blockchain technology is no exception. However, due to the security of the financial industry , Real-time requirements, but also higher requirements for technology. [0003] A smart contract is a computer protocol designed to disseminate, verify or execute contracts in an informatized manner, and its execution process is consensus and confirmed on the blockchain in the form of transactions. Smart contracts allow for trusted transactions without third parties, which are traceable and irreversible. [0004] A smart contract is a piece of code that runs on the blockchain and needs to be publis...
