Proof of Opinion
Put your name on a take onchain, mint a shareable badge, others co-sign.
Five people who know you vouch for your honesty, privately aggregated into one trust score.

Seun is new to a P2P lending circle. Five long time friends anonymously rate his honesty, Character Circle publishes only the aggregate, and the circle lets him in without anyone knowing who said what.
Vouch invites, encrypted ratings, aggregate reveal at threshold, trust badge.
Reshape it entirely: new features, your flows, your brand end to end, integrations you need. We scope it with you.
No product found that privately aggregates peer character vouches into a single disclosed score.
Gitcoin Passport and BrightID verify humanity; VouchMe (ETHGlobal) makes vouch trees public and trust-store computes offchain graph scores, but none do private aggregate character vouching.
Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.
If built on Fhenix FHE; eligibility unknown.
The complete Character Circle app: people who know you rate you in private, only the combined score is revealed, and you get a fading trust badge circles and landlords can check, with a paywall and USDC checkout built in.
Every buyer gets the same finished app. Basic branding and copy changes come through a quick form.
Your admin side: revenue, paywall editor, users, rules and the agent log.
Referral and growth mechanics, switched on when you are ready to grow.
Applicants never pay to be vouched for or to vouch. Applicants pay for extra rounds and landlord check links, organisers pay to run circles, and verifiers pay per badge check.
Verifiers pay $0.50 per badge check. FHE and badge gas, a few cents per round, can be sponsored by the owner.
Prices are yours to set. Illustrative, not a promise of income.

Custom work covers your own traits and wording, other languages, circle specific rules, your own badge design, and integrations with your community's tools. Scoped on a call.
The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.
Savings circles, lending groups, landlords and small communities decide who to trust by asking people to vouch in public. Friends will not say anything negative in front of others, so vouching tells you little. Newcomers with no local history are shut out, and fake friends are easy to recruit.
Gitcoin Passport and BrightID verify that someone is a unique human. VouchMe (an ETHGlobal project) builds public vouch trees, and trust-store computes graph scores offchain. Research verdict: fresh, high novelty. We found no product that collects encrypted character ratings from people who know someone and reveals only the aggregate at a threshold. That private aggregation, with collusion rings counted once, is the new part.

Let people be honest about each other in private, so newcomers can be trusted on what those who know them really think.
One number, no names Nobody, not even the organiser, ever sees who gave which rating. That is what makes friends honest.
Vouch back Every person you vouch for can vouch for someone else, so trust spreads person to person.
Fresh or fading Badges fade after a season unless people still vouch, which brings everyone back each quarter.

Cost per use: unlocked when your app is paid in full.
Every voucher sees how the app works from the inside and can start their own round. Organisers who caught a ring tell other circles. Badges get shown to landlords and new groups, and each check page invites the viewer to set up their own circle.

Nine routes from one vessel. Tap a port to open its chart.
Character Circle lets five people who know someone vouch for their honesty privately, then publishes only the aggregate as a trust score. If a lending circle or community uses someone else's reputation service, that service owns the trust graph and decides what counts. Own it, and the vouch flow, the encrypted ratings and the trust badges belong to your community and your wallet.
Yes, some will. The score says 'five people who know them rated them', nothing more. Communities should use it as one signal, not a guarantee. Say that on every badge.
Ratings are encrypted and only the aggregate is revealed once the threshold is met. Keep the threshold at five or more so individual ratings cannot be guessed.
Invites, encrypted ratings, reveal and badge come built. You set the threshold and branding.
It could. Encourage communities to use it to let people in, not to shut them out, and to offer another path for people without five vouchers yet.
Yes. Deployed from your wallet on Base or Fhenix.
Communities, lending circles and marketplaces pay a monthly fee to use private vouch scores for onboarding, plus per circle fees for one off checks. This is a target, not a promise.
Illustrative stages, not a forecast. Results depend on you and the market; nothing here is guaranteed.
