Methods for integrating dynamic type programming languages ​​on blockchain

Methods for integrating dynamic type programming languages ​​on blockchain

I. Review of knowledge points

1. Blockchain technology

Relationship between Bitcoin and blockchain: Bitcoin is a digital currency, and blockchain is the underlying technology of Bitcoin, like a database ledger, recording all transaction records.

Structure of blockchain: Blockchain is composed of many nodes, each of which stores complete blockchain data.

Smart contract: Smart contract is a program code written and stored on each node of the blockchain. All nodes on the blockchain can implement related functions by executing smart contracts.

2. Static type programming language and dynamic type programming language

Static type programming language: The data type of the variable needs to be determined in the compilation stage, such as Solidity.

Dynamic type programming language: The data type of the variable is determined only in the running stage, such as Javascript.

Advantages and disadvantages of the two programming languages: The code of static type programming language is rigorous, but the scalability is poor; the code of dynamic type programming language is flexible and scalable, but the code is prone to errors.

3. Technical solution of the present invention

Purpose: To solve the problem of low scalability of blockchain smart contracts in the prior art.

Method: Use dynamic type programming language to write smart contracts on blockchain.

Implementation steps:

Compile the smart contract into bytecode and store it in each node on the blockchain.

When the node calls the smart contract, the bytecode is parsed by the bytecode interpreter to obtain a smart contract with undefined variable types.

Define the variable type of the smart contract according to the requirements, and then execute the smart contract.

Advantages: Improve the scalability of smart contracts on the blockchain.

3. Answer

Blockchain is a decentralized distributed database used to record all transaction information. Bitcoin is a digital currency, and blockchain is the underlying technology of Bitcoin.

Smart contracts are program codes stored on the blockchain, which can automatically execute pre-set rules. Smart contracts can be used in various application scenarios, such as digital asset transactions, supply chain management, etc.

Statically typed programming languages ​​need to determine the data type of variables at the compilation stage, while dynamically typed programming languages ​​determine the data type of variables at the runtime stage.

In the prior art, blockchain smart contracts are mainly implemented using statically typed programming languages, such as Solidity. The problem is that the code has poor scalability and is difficult to adapt to changing needs.

The present invention proposes to use a dynamically typed programming language to write smart contracts to solve the problem of weak scalability of smart contracts in the prior art.

The present invention first compiles the smart contract into bytecode and stores it in each node on the blockchain; when the node calls the smart contract, the bytecode is parsed by the bytecode interpreter to obtain a smart contract with undefined variable types; finally, the variable type of the smart contract is defined according to the requirements, and then the smart contract is executed.

Bytecode is an intermediate form of machine code, which can be interpreted and executed by different platforms. In the present invention, bytecode is used to store and distribute smart contracts.

A bytecode interpreter is a program used to convert bytecode into machine code and execute it. In the present invention, a bytecode interpreter is used to parse the bytecode of a smart contract and perform corresponding operations.

Compared with the prior art, the solution proposed in the present invention has the advantage of improving the scalability of smart contracts on the blockchain, enabling it to better adapt to changing needs.

The "memory" in the present invention refers to a special area in a smart contract for storing data. It is stored on the blockchain and is queried and modified by the code logic in the smart contract when the smart contract is called and executed. The memory can store numbers, Boolean values, strings, mapping tables and arrays.
