Validator
Network participants who check miners' work and distribute rewards in Bittensor's subnets.
What is a Validator?
Validators act as judges in Bittensor's network. They check miners ' work and give out rewards based on quality. To make these decisions, validators need authority through staked TAO tokens. A validator can become a delegatee to accept additional stake from nominators , increasing their influence in the network.
VALIDATOR'S NETWORK ROLE
Validators power Bittensor's Proof-of-Intelligence system. They create tasks for miners to solve and check their answers. Through the Yuma Consensus system, they rate miners' work and compare scores with other validators. This creates a trust score called V-Trust. Validators who rate fairly and match the consensus earn higher rewards.
Subnet Participation and Permits
Each subnet allows 64 validators to participate through validator permits. These permits go to the validators with the most stake in each subnet. The minimum stake needed starts at 1,000 TAO but changes based on the current stake distribution. This competitive system ensures validators have a strong interest in the network's success and maintains high-quality validation.
Economic Model
The network creates new TAO tokens every 12 seconds. In each subnet, validators receive 41% of new tokens.
As delegatees, they can keep between 0% and 18% of rewards from delegated stake. The remaining rewards go to their nominators.
Root Network Validation
The largest 64 validators across all subnets become root network validators. These validators take on a broader role by evaluating entire subnets instead of individual miners. Their decisions guide how rewards flow throughout the network.
