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.

This article explains Flow’s recent implementation of Proof of Possession (PoP) for staking keys, a small but critical step in its decentralization roadmap. The article covers why PoP is needed, what risks it prevents, and how it was implemented in Flow. Whether you’re a developer, validator, or simply curious about blockchain security, this post gives you a clear view of why PoP matters — with optional technical dives for those who want to explore the cryptography details.

Flow dominated ETH Global once again, with one in every four hackers building on Flow. At ETHGlobal New York 2025, Flow was the number 1 network of choice for developers as the most hacked on technology across the entire hackathon. A result of committing to empowering builders, community scholars and exciting the imagination of builders through groundbreaking keynotes redefining what’s possible onchain

Launching October 22nd, Forte is the Flow network upgrade that brings composability and automation natively to Flow. Two new primitives, Actions and Agents, let developers compose reusable, protocol-agnostic agents with onchain time-based triggers.

The Cadence smart contract programming language utilizes a powerful new concept for access control: entitlements. These work alongside capabilities, references, and interfaces to give developers unprecedented flexibility in how they define access, enforce security, and enable composability in applications.

Flow has rolled out an important upgrade that significantly enhances how NFTs can move between EVM and Cadence.

Generating randomness on-chain is notoriously hard. You need a number that’s unpredictable before it’s revealed, unbiased during its generation, and verifiable afterward. To make things even more challenging, nodes of the network have to generate and agree on random numbers in a distributed and decentralized manner. With these nearly opposing constraints, traditional random functions (like Math.random()) aren’t an option.

Following standout appearances at ETHGlobal events from San Francisco to Bangkok, Flow made a powerful mark at ETHGlobal Taipei, showcasing why it’s quickly becoming the Layer 1 of choice for Developers. From an amazing sunset cruise to strong hackathon participation, Flow continued its mission: empowering developers to create real-world consumer applications that scale.

Flow is pushing the boundaries of blockchain efficiency and scalability.

The Flow team is heading to Taipei! Join us at the ETHGlobal Hackathon from April 4–6, 2025, where Flow is sponsoring $10,000 in bounties for developers building the next wave of consumer crypto applications. Whether you’re working on games, AI agents, RWAs, or social apps—Flow is the chain that gets you to real users and energized communities, fast.

The Flow foundation is excited to announce its latest release: a Wagmi & RainbowKit adapter for FCL that empowers developers to seamlessly integrate Cadence into existing EVM applications.

Superior Web3 apps start with reimagining UX. Flow’s EVM compatibility + Cadence enable seamless atomic transactions, reducing friction & unlocking new possibilities.

From December 1st to 31st, developers across Asia compete online to build the next killer app on Flow.

With 99 apps built on Flow and over 2000 builders, nearly one-third of ETHGlobal winners were Flow projects.

Flow is home to games that scale to millions, like NBA Top Shot, with great UX and and features like true randomness empowering devs to create the next killer app.
