Solidity is a high-level programming language designed specifically for writing smart contracts on the Ethereum platform. It was developed by [[Gavin Wood]], Christian Reitwiessner, Alex Beregszaszi, and several other contributors. Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They automatically execute predefined actions once certain conditions are met. Solidity is statically typed and supports inheritance, libraries, and complex user-defined types among other features. It is similar to [[JavaScript]] in terms of syntax and structure, making it relatively easy for developers to learn and write code in Solidity if they have experience with JavaScript. Some key features of Solidity include: 1. Contract-oriented: Solidity focuses on contract-based programming where code logic is encapsulated within a contract that interacts with other contracts or users. 2. Security: Solidity has built-in security measures to prevent common vulnerabilities such as reentrancy attacks, integer overflows/underflows, and more. 3. Modularity: Solidity allows developers to create reusable libraries that can be imported into multiple contracts, promoting code reuse and reducing redundancy. 4. Ethereum integration: Solidity has native support for interacting with the Ethereum Virtual Machine (EVM) and accessing blockchain data such as account balances, transaction history, etc. 5. Auditing tools: Several tools exist to analyze Solidity code for potential vulnerabilities and security issues before deployment. Solidity is widely used in the development of decentralized applications ([[Literature/PKM/Tools/DataGovernance/dApp|dApps]]) on Ethereum as it enables developers to define smart contract logic that governs the behavior of these applications on the blockchain. By leveraging Solidity's capabilities, developers can create trustless systems that are transparent and resistant to censorship or fraud. # References ```dataview Table title as Title, authors as Authors where contains(subject, "solidity") ```
