Writing your first smart contract in Cadence

on YouTube ↗55m

" summary

Cadence on Flow uses resource-oriented programming with linear-type resources that live in user accounts (not a central ledger), so assets can’t be copied and the runtime errors if a created NFT is not explicitly saved or destroyed — the demo shows creating an NFT in the Playground emulator, hitting a “loss of resource” error, then fixing it by account.save. Transactions are atomic and can run arbitrary code; access control relies on capability security. The language is currently interpreted; a compiler is planned.
