As blockchain technology evolves, we’re seeing more and more platforms, languages, and apps. The latest development is presenting and trading your works of art and collectibles in the form of non-fungible tokens (NFTs). Most NFTs are part of the dominant Ethereum, but the promising Flow blockchain is close on its heels.

Flow allows the release of smart contracts on its mainnet in a “beta state” so that the original author of the contract can update the code step by step. Users, in their turn, can choose to use the code as it is at a given point in time, or wait for the code to be completed before they put their trust in it.

Once the authors of smart contracts are convinced that the code is safe, they no longer need to control the code, and from that moment the smart contract becomes immutable. By checking and fixing the code, developers have the opportunity to significantly improve the security of smart contracts for end users.

• The FlowFees contract is where all the collected flow fees are gathered.
• FLOW is the default token for the Flow protocol, meaning it is used for all protocol-level fee payments, rewards and staking transactions. FLOW implements the standard Flow Fungible Token interface, which all other on-chain fungible tokens also conform to. This interface is defined in Cadence, Flow's native smart-contract programming language, which makes it easy to write applications that interact with FLOW.
