Flow transactions reach cryptographically-backed soft finality in ~4 seconds and hard finality in ~10 seconds — not minutes or days. Learn how Flow minimizes reorg risk, eliminates optimistic assumptions, and enables DeFi and app experiences with real economic guarantees and near-instant certainty.

Most NFTs store their artwork off-chain, on IPFS, Arweave, or centralized servers. The metadata might point to ipfs://Qm... or https://api.example.com/token/1, leaving the actual image hosted elsewhere. This works, but it introduces dependencies. IPFS gateways go down. Centralized servers get shut off. Your "permanent" NFT suddenly has a broken image.On-chain SVG NFTs solve this by storing the artwork directly in the smart contract. The SVG markup lives on the blockchain forever, rendered by any browser that reads the token's metadata. No external dependencies. No broken links. True permanence.

Flow is upgrading its primary USD stablecoin from USDF to PYUSD0. Users can convert USDF 1:1 to PYUSD0.

Modern development increasingly relies on pairing developers with AI assistants, and @onflow/react-sdk is the first Flow toolkit designed specifically for this reality.

Over 3,300 builders. More than 400 projects. $250,000 in prizes. Forte Hacks brought together some of the brightest builders from across the globe to create the next generation of onchain finance, from yield protocols to prediction markets to onramp in developing countries and DeFi tools built for everyone.

Blockchain and Web3 development can seem intimidating at first, but the Flow network and its smart contract language Cadence make it surprisingly accessible. This guide walks through building a complete blockchain application from scratch, all the way to a working "Hello World" example with a React frontend.
