# Intro to Bird Chain

Bird Chain deployment to deliver fast transaction speeds, low transaction costs, and deterministic finality, This is achieved while remaining permissionless, decentralized, and open-source.

Unlike other solutions, Bird Chain does not sacrifice security and decentralization in favor of scalability.
