Solidity is a programming language for writing smart contracts on the Ethereum blockchain, offering tools and resources for building decentralized applications (DApps) and blockchain solutions. Developers can learn about smart contract development, Ethereum development tools, and decentralized finance (DeFi) to create secure and reliable blockchain applications using Solidity.

The Solidity team announces their long-term roadmap as the language reaches its 10-year milestone. Development splits into two tracks: Classic Solidity (current 0.x versions) will continue with incremental improvements and breaking releases, while Core Solidity represents a ground-up redesign featuring generics, first-class functions, algebraic data types, and a community-driven standard library. Backend work focuses on fixing IR pipeline issues, implementing ethdebug specification for better debugging, and preparing for EVM upgrades. The transition aims for gradual convergence with interoperability between both versions, ultimately leading to version 1.0 when Core Solidity stabilizes.
