Vyper: Secure and Auditable Smart Contract Language
With the rise of blockchain technology, programming languages play a pivotal role in building decentralized applications. Fundamentally, smart contracts on Ethereum blockchain necessitate powerful, secure, and easily auditable programming languages, and one such language is 'Vyper'. It is an Ethereum based project hosted on GitHub that aims to accomplish these needs and has a significant relevance in the Ethereum ecosystem.
Project Overview:
Vyper, developed by the Ethereum community, targets one primary goal - to create a simpler, more secure, and more auditable programming language for writing Ethereum smart contracts. The language is directed towards lessening the likelihood of bugs and making it easier to understand and verify smart contracts' correctness. Vyper's straightforwardness makes it an excellent tool for developers and auditors who want to write or review smart contracts.
Project Features:
Vyper has distinctly centered features that help it achieve its objectives. Firstly, it enforces secure coding and restricts developers from writing potentially harmful code. Secondly, it supports static typing and bound checking, which promotes early bug detection. Thirdly, the ‘DECORATORS’ system offers in-built protections against common hazards. It also uses 'modifying clauses', a feature that enables developers to ascertain and implement how a function can modify the state. Additionally, its uncomplicated and easily readable syntax makes auditing contracts a less complex task.
Technology Stack:
Vyper programming language, which is designed using Python 6, compiles smart contracts into EVM (Ethereum Virtual Machine) bytecode. Python's simplicity directly transpires into Vyper, which is reminiscent of Python. It also uses several Python testing tools for enhanced performance and debugging. Importantly, the Vyper compiler is an essential part of the project, ensuring the secure execution of the contracts.
Project Structure and Architecture:
The architecture of Vyper consists of numerous files and directories with defined functions for each. Its directories include 'Vyper,' 'tests,' 'docs,' and several others. The 'docs' section encompasses detailed instructions about the implementation of the language, while the 'tests' directory holds the test cases. The 'vyper' directory, on the other hand, comprises the compiler and other Vyper language files. Vyper's simplicity and direct mapping to EVM operations contribute to its uncomplicated design architecture.
