Embodiment 1

[0116] figure 1 It is a schematic flow chart of a coding method based on a blockchain smart contract provided by the embodiment of this specification, including the following steps:

[0117] S100: A node in the blockchain network obtains a business and initiates a transaction and broadcasts it to other nodes.

[0118] S102: For each node in the blockchain network, when executing the business initiation transaction, the node invokes the business smart contract through the blockchain virtual machine.

[0119] S104: The node uses the blockchain virtual machine to trigger the execution of the BASE64 encoding logic according to the BASE64 encoding instruction in the business smart contract, so as to perform an encoding operation on the data to be encoded.

[0120] In this embodiment, it is necessary to pre-configure the blockchain network so that:

[0121] 1) The instruction set of the blockchain virtual machine includes BASE64 encoded instructions, and the blockchain virtual mac...

Abstract

A BASE64 encoding and decoding method and system based on blockchain smart contracts are disclosed. In the embodiment of this specification, on the one hand, BASE64 encoding instructions and BASE64 decoding instructions are defined and added to the instruction set of the blockchain virtual machine, and at the same time, the BASE64 encoding corresponding to the BASE64 encoding instruction is deployed in the blockchain virtual machine The logical sum corresponds to the BASE64 decode logic of the BASE64 decode instruction. On the other hand, it is also necessary to add the defined BASE64 encoding instructions and BASE64 decoding instructions to the instruction set of the smart contract compiler, so that the business smart contracts compiled by the smart contract compiler include BASE64 encoding instructions and / or BASE64 decoding instructions. In this way, if the business smart contract is deployed in the blockchain network, when the user constructs a business initiation transaction, he can specify to call the business smart contract to execute the business initiation transaction at the same time.

Description

technical field [0001] The embodiments of this specification relate to the field of information technology, and in particular to a coding and decoding method and system based on blockchain smart contracts. Background technique [0002] At present, by deploying smart contracts in the blockchain network based on the Ethereum protocol, various online business needs can be met. [0003] In practice, for some business needs, each node in the blockchain network needs to perform encoding and decoding based on 64 printable characters (BASE64) when calling the smart contract corresponding to the business demand through the Ethereum virtual machine to execute the business. operate. [0004] However, the existing Ethereum virtual machine does not support BASE64 encoding and decoding operations by default. Contents of the invention [0005] In order to solve the problem that the existing Ethereum virtual machine does not support BASE64 encoding and decoding operations by default, th...
