Bittensor is an open-source protocol that facilitates a decentralized, blockchain-based machine learning network. It allows developers to build, train, and share machine learning models collaboratively, leveraging global computational resources. Participants are incentivized with TAO, Bittensor's native cryptocurrency, rewarding contributions based on the informational value they provide. This approach fosters a transparent and community-driven ecosystem for artificial intelligence development, aiming to democratize access to AI technologies and create a marketplace where consumers and producers of machine intelligence can interact in a trustless, open, and transparent environment.
