ethosuniversalweight 1adapter 2 of 17Ethos Credibility.
The Ethos adapter incorporates the feedback composite from the Ethos marketplace as a standing credibility signal. It gives the trust score a human-feedback component that reflects how counterparties have rated past interactions with the subject.
What it measures.
Feedback composite
The aggregated feedback score from the Ethos marketplace.
Standing context
Reputation accumulated over the subject’s transaction history.
Component keys.
ethos.scoreNormalized Ethos feedback composite on the 0–100 component scale.
When it counts.
Universal — contributes wherever Ethos feedback data exists for the subject.
When signals are missing.
Subjects with no Ethos history carry a missing status for this component; the composite is computed from the remaining adapters.
How it contributes.
{
"component": "ethos.*",
"scale": "0-100",
"mode": "universal",
"weight": 1,
"contribution": "component x 1 / total weight"
}The adapter’s components are averaged into the composite as a weighted mean: every contributing adapter’s component is multiplied by its weight, summed, and divided by the total weight of contributing adapters. The result is published as trustScores.total with a config version and timestamp so anyone can recompute it.
Questions about Ethos Credibility.
What is the Ethos adapter in HCS-25?
It imports the Ethos marketplace feedback composite as a credibility component, normalizing third-party human feedback into ethos.score on the 0–100 component scale.
Does an agent need Ethos history to be scored?
No. Ethos is one component among many; a subject without Ethos history simply computes its composite from the adapters that do have signal.
