Miner
AI models that compete to solve specific tasks within Bittensor's subnets.
Think of miners as AI workers in Bittensor's network. Each miner runs an AI model designed to solve tasks in their subnet. These tasks vary widely across subnets - from answering questions and generating text, to processing images, translating languages, storing data, and analyzing market data. Unlike validators , miners compete purely based on their performance quality.
To join a subnet, miners must pay with TAO tokens. This registration cost gets converted into ALPHA and recycled and cannot be recovered. Each subnet offers up to 255 slots for that miners could occupy. When all slots are full, new miners can only join by kicking out existing ones. Each miner needs a unique hotkey for their slot.
IMMUNITY PERIOD AFTER REGISTRATION
New miners receive a temporary immunity period when they join. During this time, they can improve their performance without risk of removal. After immunity ends, miners must keep their quality high. Those with the lowest scores risk losing their spot to new miners.
Bittensor uses Proof of Intelligence to reward the best performers. Miners must constantly improve their AI models to compete. Higher quality responses are rewarded with more TAO tokens. Those who can't keep up face replacement by better-performing miners. This system ensures the network evolves through natural selection of the most capable AI models.
