Scripts executed on blockchain platforms

Scripts executed on blockchain platforms

System and method overview:

System and method: A computer-implemented method and system are provided to allow or facilitate the execution of source code portions written in a high-level language on a blockchain platform.

Target platform: Supports multiple blockchain platforms including the Bitcoin blockchain.

Blockchain compiler:

Function: Receives high-level language source code as input and generates an output script containing a series of op_codes compatible with the blockchain scripting language.

Scripting language characteristics: The blockchain scripting language is functionally limited and does not support complex control flow structures or recursion.

Op_codes:

Selection: The op_codes in the output script are a subset selected from the functionally limited blockchain scripting language.

Static compilation: The step of generating the output script may include static compilation, such as loop unrolling.

High-level language (HLL) characteristics:

Language type: The high-level language can be a compiled language, such as C, Java, etc., allowing complex control flow structures and recursion.

Primitives and constructs: The HLL may contain primitive operations or constructs that can be directly translated into blockchain scripting language primitives.

Smart Contract Support:

Application: Source code can be designed to implement smart contracts, which are machine-readable and executable applications that can be automatically executed on the blockchain.

Verification and Execution:

Verification process: In order to write a transaction on the blockchain, the transaction must be verified, which includes executing the lock and unlock scripts of the transaction.

Execution Environment: The blockchain scripting language may be stack-based and used to operate one or more stacks when executed on the blockchain.

Optimization and Efficiency:

Optimization Steps: The output script may be optimized at least once to provide a more efficient or streamlined version.

Optimization Techniques: Optimization may involve techniques such as derivative-free optimization (DFO).

Development Tools:

Software Development Kit (SDK): The system and method may include an SDK, including components such as an editor and a debugger, to simplify the generation of blockchain-based code solutions.

Implementation and Examples:

Implementation: The document provides multiple implementations and examples, including examples of high-level language constructs (such as WHILE loops) and detailed steps on how these constructs are compiled into blockchain scripts.

Sample code: Includes a specific high-level language program example that is designed to check the match between the input value and the pre-stored hash value and show its compiled blockchain script form.

Computing environment:

Blockchain network: Describes the structure of the blockchain network, including nodes, miners, transaction verification, and mining processes.

Computing devices: Discusses the computing devices that can be used to implement blockchain compilers and network nodes.

This document details how to convert code written in a high-level language into executable scripts on the blockchain, providing blockchain application developers with a more intuitive and efficient development method while maintaining the security restrictions of the blockchain scripting language.
