DeltaOne Explained
A technical overview of how Hokusai measures marginal improvement and turns it into protocol rewards.

DeltaOne is the protocol's way of asking a strict question: did this contribution move the decision layer forward in a measurable way?
That framing matters because high-quality AI infrastructure cannot rely on vague engagement metrics. It needs a reward surface that maps to real changes in model behavior, benchmark quality, or production routing outcomes.
At an implementation level, contributions can be normalized into a scoring pipeline:
type Contribution = {
baselineScore: number
candidateScore: number
confidence: number
}
export function computeDeltaOne(contribution: Contribution) {
const improvement = contribution.candidateScore - contribution.baselineScore
return improvement * contribution.confidence
}The exact function will evolve, but the principle stays fixed: rewards should anchor to verifiable improvement, not narrative.
