REFS, a Reputation Ledger for Trading Cards

Field notes

REFS records card purchases, sales, and trades only after the other party confirms them, then opens a 30-day evaluation window. Its rules specify a 14-day confirmation deadline, one-hour correction period, and evidence requirements for claims of being defrauded. The scoring model also discounts evaluations from tightly connected trading circles, an attempt to limit reputation inflation among friends. The page says entry happens through WhatsApp and that the service has no subscription or advertising plan.
