Is Bittensor's "machine learning mining" model sustainable? Bittensor incentivizes miners to contribute AI models via TAO tokens, fostering a decentralized marketplace for intelligence. Its Yuma Consensus ensures validator agreement, rewarding high-quality outputs while penalizing inefficiencies. Unlike Bitcoin's energy-intensive mining, Bittensor's model leverages computational creativity, potentially reducing environmental impact. However, sustainability hinges on TAO token economics—dynamic registration costs and halving delays could strain liquidity. Scalability challenges arise as subnets grow, demanding robust validation to prevent gaming. While open-source collaboration drives innovation, economic incentives must align with long-term AI development to avoid short-term profiteering.
