A Green Web3 Network

Flow starts with HotStuff, a proven proof-of-stake consensus mechanism, and adds a unique multi-node architecture to drive dramatic improvements in speed, throughput, and environmental friendliness without sharding or "layer two".  

This means Flow is the greenest Web 3 network among leading platforms. Minting an NFT on Flow costs less carbon than a post on a social networking site.

    Flow Proof of Work

    No Sharding

    On Flow, every application can be a platform.

    Smart contracts and user accounts on Flow can always interact with each other in one atomic, consistent, isolated, and durable (ACID) transaction. In other words: all applications on Flow can run in the same shared execution state.

    This ensures Flow apps benefit from great user experience and full composability, letting developers easily build on each other’s work.

    Sharding and layer 2 solutions break composability and reduce network effects for dapps and smart contracts by removing ACID guarantees from the execution environment.
