A credential is only worth what you can check.
Most credentials ask for trust. A Signal is built to be checked.
A seal anyone can check, that fails the instant it's altered.
Like a wax seal: visibly genuine, impossible to forge, broken if touched.
GOS-signed with Ed25519. Public keys published; private keys never leave issuance.
Signed when issued
A unique digital signature, added at issuance.
Anyone can confirm it
One link, no account, nothing to install.
Change one character, it fails
Faked by no one. Checkable by everyone.
It proves the credential is real — and tells you nothing else.
Back from a check: valid or invalid, issued date, expiry. Nothing more.
No personal data, ever
Validity and dates only — nothing about the person.
Groups of five or more
Cohort numbers hidden below five, so no one's singled out.
Consent before identity
Employers see identity only when the learner agrees.
DPDP-aligned by design
Built to India's DPDP Act 2023, not bolted on.
Earned on evidence. Carried by the learner. Checkable by anyone.
Issued on evidence
Only after assessed work clears a fixed checklist.
Carried by the learner
The holder owns it and decides who sees what.
Checkable by anyone
Public keys, no account, in seconds.
Expires & revocable
Readiness is a snapshot — revoke any time.
Every Signal speaks the same language.
Eight clusters, C1 to C8, read the same way by everyone.
Check a real Signal yourself.
A fictional learner, a real seal. Watch it verify green, live.
