Bittensor is a decentralized, blockchain-based machine learning network that operates on an open-source protocol. Collaborative training of machine learning models is incentivized through rewards in TAO, based on the informational value they provide to the collective. External access to the network is granted, allowing users to extract information while customizing its activities to their requirements. The ultimate goal is to establish a trustless, open, and transparent marketplace for artificial intelligence, where consumers and producers can interact. Bittensor enables optimized development and distribution of AI technology through a distributed ledger, decentralized governance, and the utilization of globally-distributed computing power and innovation within an incentivized framework. Additionally, it offers an open-source repository of machine intelligence, fostering open and permission-less innovation on a global scale. Rewards and network ownership are distributed directly to users based on the value they contribute.
