Flow

Flow is a proof-of-stake Layer 1 conceived by people from Axiom Zen and Dapper Labs after CryptoKitties' 2017 demand exposed the cost, throughput and upgrade limits of Ethereum-era consumer applications. Its transaction path assigns collection, ordering, execution and verification to different node roles instead of asking every validator to repeat every computation.

The chain now has two application environments. Cadence stores valuable assets as resources with language-enforced ownership rules. Flow EVM, introduced with the Crescendo upgrade on September 4, 2024, runs Ethereum-compatible bytecode and uses FLOW as gas on mainnet chain ID 747. These are two execution environments on one Flow network, not two unrelated FLOW tokens.

CryptoKitties proved demand before it proved infrastructure. The game attracted users who then met congestion, volatile fees and product friction. The team responded with a pipeline: collection nodes batch data, consensus nodes order it, powerful execution nodes compute state changes, and verification nodes re-check the deterministic result. The design keeps more redundancy where ordering can be manipulated and less where a result can be checked.

That choice creates its own question. Flow's protocol vision explicitly accepts a small set of professionally operated execution nodes—ten or fewer in its mature design example—and relies on verification to catch bad work. An Observer node can be run without stake, but the validator roles that make blocks have large, role-specific stake requirements. Accessibility to data and authority in consensus are therefore different kinds of participation.

FLOW pays transaction fees, backs account storage, and is staked by validator operators or delegated to them. Current published minimums are 250,000 FLOW for Collection, 500,000 for Consensus, 1,250,000 for Execution, 135,000 for Verification and 100 for Access nodes. Delegation starts at 50 FLOW and the protocol assigns an 8% operator take-rate. Access nodes are staked gateways but earn no rewards and cannot receive delegations.

The 2020 genesis allocation was 1.25 billion FLOW: 400.2 million for the ecosystem fund, 374.8 million for pre-launch backers and the community sale, 250 million for Dapper Labs and 225 million for the development team. All genesis allocations were unlocked by October 2023. There is no fixed maximum supply: each epoch's target reward pool equals 5% of total supply on an annual basis, transaction fees fund it first, and the protocol mints the shortfall. Fees are not burned. The December 8, 2025 fee update is designed to make net issuance negative only at sustained 250 TPS. Separately, the Foundation completed destruction of 50,343,896.87 FLOW on February 23, 2026; its promised purchase of at least 50 million more was a future commitment, not evidence of completion.

The canonical Cadence FlowToken contract is deployed at 0x1654653399040a61. Core contracts also cover fees, storage, staking, epochs and the service account. FLIPs let anyone propose changes, including staking rules, node allowlisting, fees and service-account actions, but maintainers and a review committee shepherd acceptance through community review. The reviewed sources do not describe every FLOW balance as an automatic binding ballot, nor do they establish equity, a claim on Foundation assets or protocol revenue, fixed-value redemption, or corporate ownership.
