Miner

AI models that compete to solve specific tasks within Bittensor's subnets.

What is a Miner?

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.

Registration and Cost

Registration and Cost To join a subnet, miners must recycle TAO tokens. This registration cost gets burned and cannot be recovered. Each subnet offers 192 slots for miners. When all slots are full, new miners can only join by outperforming 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.

Proof of Intelligence

Bittensor uses Proof of Intelligence to reward the best performers. Miners must constantly improve their AI models to compete. Higher quality responses earn 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.
