Mastering Web3 with Waves

Ride introduction

Ride is a purpose-designed smart contract language for the Waves Platform, created to address shortcomings in other blockchain programming languages. It offers a straightforward, developer-friendly approach to building decentralized applications (dApps) with predictable execution costs and enhanced security. ## Key Features - **Statically-typed & Functional** — A lazy, expression-based language influenced by Scala and F#, ensuring code clarity and safety. - **Non-Turing Complete** — No loops or recursion at the VM level, with iterations handled via FOLD macros for predictable execution. - **Predictable Execution Cost** — All code executes as intended with no failed transactions recorded on-chain, eliminating a major pain point. - **Blockchain-Optimized** — Designed specifically for blockchain environments, with no filesystem or console access, only blockchain data reading and action returns. - **Secure by Design** — Immutable variables, no null values, and built-in limitations to prevent common vulnerabilities. - **Annotations for dApps** — Supports `@Callable` and `@Verifier` annotations for defining invocable functions and transaction validation rules. - **Rich Standard Library** — Includes predefined blockchain data structures like `Address`, `DataEntry`, and `ScriptTransfer` for seamless dApp development. ## Philosophy Ride prioritizes simplicity, security, and predictability, making smart contract development accessible while ensuring robust and reliable dApp execution on the Waves blockchain.
