Bittensor expands subnet capacity to 2,500 miners, opening autonomous AI agent participation

Bittensor's Null Consensus update expands subnet capacity from 256 to 2,500 participants and introduces PoW registration as an alternative to Yuma Consensus.

Under the default mechanism, registering a miner requires burning dynamically priced TAO, which gets expensive on competitive subnets. PoW registration instead lets miners join by solving a computational challenge, removing the capital gate. This targets capital-light participants — pure compute nodes and AI agents in particular — enabling an agent to spin up, register itself and compete for emissions using only hardware it already has.
