Credibility Score

Credibility Scores quantify credibility indicators.

Calculation

The Credibility Score algorithm will factor in a variety of weighted indicators. Indicators include relevant on chain actions, such as:

• number of vouchers, mutual vouches, and amount vouched

• mutual vouch duration and defection

• credibility score of vouchers

• average review rating and volume of reviews

• participation in reviews, attestation, and social validation

• participation in Ethos governance

Weights do not need to be linear. For example, having 100 positive reviews may provide 2x more credibility than 10 positive reviews.

Indicators and weights may be added, removed, or adjusted according to the Credibility Consensus.

Range

The score is an unbounded positive decimal; [0.0, ∞). The default credibility starts at 1.0.

It's upwardly unbounded because financial backing represents many magnitudes of power. Someone with $1b represents more financial influence than someone with $10, regardless of non-capital elements of their reputation.

Usage

Credit Scores are intended as an "at a glance" quick estimate of credibility across many domains. No single number can represent the complexities of one's reputation among that many groups and interactions. Different communities' needs may warrant additional weights and calculations. Ethos open protocol allows other dApps to define alternate scores using the same on chain records.

Under the hood

The credibility score will be calculated using on chain Ethos protocol data only. The algorithm will be committed to the Ethos Smart Contract, with all details publicly verifiable.

Other dApps may surface alternative credit scores.
