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.
