プロジェクトの歴史

The Cadence repository says the language has been open source since 2019 and is the native smart contract language of Flow. Official docs present it as a high-level language created to make digital assets first-class resources: values can be moved but not accidentally copied, lost, or implicitly destroyed.

Cadence draws syntax and safety ideas from Swift, Kotlin, Rust, TypeScript, Solidity, Move, and design-by-contract traditions while targeting Flow's account-storage model. The v1.0.0 release states that Cadence 1.0 culminated five years of work since inception, with no more planned breaking changes, full forward compatibility, entitlements, attachments, and storage/performance improvements.

採用の歴史

Cadence adoption follows Flow adoption: developers use it to write and deploy Flow smart contracts, transactions, and scripts. The README points users to the browser playground, Flow CLI, Flow emulator, VS Code extension, Cadence language reference, and Flow developer portal.

Flow ecosystem examples in the README include consumer applications such as NBA Top Shot, NFL All Day, Disney Pinnacle, and Ticketmaster NFT ticketing, making Cadence notable as a domain-specific package for production blockchain applications rather than a general-purpose language runtime.

使われ方

Package users typically install the cadence command to run, parse, test, or work with Cadence code locally, while end-to-end Flow development usually also involves Flow CLI, the emulator, contracts, transactions, and the Cadence Playground. The language itself is used for smart contracts and transaction code stored and executed on Flow.

パッケージ好きにとっての重要性

Cadence is interesting to package nerds because it packages a language implementation for a blockchain runtime, not just a compiler. It brings together parser, interpreter/runtime, language server and tooling expectations, versioned language migrations, and network compatibility concerns around Flow's on-chain execution model.
