BFT Data Consensus Algorithm
BFT data consensus algorithm is the key mechanism for PublicAI to guarantee the quality of data which consists of two phases:
AI Screening Phase
Once the uploader uploads the data to the platform, our corresponding AI agents will filter it as the first step to mitigate the cost of human verification. Those AI agents are various in terms of data.
Human Voting Phase
After the uploaded data is accepted by AI agents, it will enter the human verification phase. Consensus is the same number of votes in the same direction. Data sample quality is binary: if a data sample is partially good then it's considered overall flawed.
We have three roles in the protocol to verify: scouts, guards, and judges with three hyper-parameters for them respectively as consensus thresholds.
Take an example from the above graph, once a data sample is accepted by the data consensus algorithm there should be at least either 50 votes from scouts, 5 votes from guards, or 1 vote from a judge.
