Bittensor is an open-source protocol that uses blockchain technology to build a decentralized neural network. It allows machine learning models to interact and learn from each other directly on-chain, creating a global brain. Bittensor aims to incentivize the creation and curation of AI models in a decentralized manner, thereby democratizing access to AI technology.

The latest introduction of Bittensor is that it has evolved into a more sophisticated protocol that not only allows for the creation of decentralized AI models but also enables these models to earn cryptocurrency. This is achieved through a unique proof-of-stake mechanism where the models stake tokens and earn rewards based on their performance.

In simple terms, Bittensor is like a global brain where AI models can learn from each other in a decentralized way. It's a blockchain-based protocol that rewards these models with cryptocurrency based on their performance.

To provide a concise overview, Bittensor is a groundbreaking protocol that combines AI and blockchain technology. It allows for the creation of a decentralized neural network where AI models can interact, learn, and earn cryptocurrency. It's an open-source project that aims to democratize access to AI and incentivize its development in a decentralized manner.
