Your Blockchain
Career Passport
Every credential you earn at Q2CareerOS™ is cryptographically hashed and permanently recorded on the Polygon blockchain — giving employers instant, tamper-proof proof of your skills.
Credential Vault™ — on-chain proof that no employer can dispute
A PDF certificate is a claim. A blockchain credential is proof. When you mint a credential here, it gets a SHA-256 hash and a Polygon transaction ID that any employer can verify on PolygonScan in seconds — without calling anyone, without trusting a third party, and without any possibility of forgery. Your skills become mathematically verifiable facts.
PDFs can be faked. Blockchain credentials can't. Every mint gets a permanent Polygon transaction hash — verifiable by any employer in seconds.
