    Use Cases & Benefits

    • Implements the Stacks blockchain as a layer-2 protocol secured by Bitcoin using Rust.
    • Enables decentralized apps and smart contracts without modifying Bitcoin by leveraging Proof of Transfer mining.
    • Use for building secure, Bitcoin-anchored decentralized applications with predictable smart contracts in Clarity.
    • Use for developing layer-2 blockchain solutions that benefit from Bitcoin's security and consensus.
    • Use for experimenting with or deploying Proof of Transfer mining mechanisms in blockchain networks.

    From the README

    Reference implementation of the Stacks blockchain in Rust.

    Stacks is a layer-2 blockchain that uses Bitcoin as a base layer for security and enables decentralized apps and predictable smart contracts using the Clarity language. Stacks implements Proof of Transfer (PoX) mining that anchors to Bitcoin security. Leader election happens at the Bitcoin blockchain and Stacks (STX) miners write new blocks on the separate Stacks blockchain. With PoX there is no need to modify Bitcoin to enable smart contracts and decentralized apps.

    For building on Windows, follow the rustup installer instructions at https://rustup.rs/.
