Do people need a SwanShare account to verify a credential?

No. Verification is public and free — anyone can check a credential with just its verification ID or the credential file, without an account and without trusting SwanShare.

What actually stops someone forging a credential?

Each credential is signed with your organization's private key using RSA-PSS. Without that key a valid signature can't be produced, and changing even one character breaks the SHA-256 fingerprint — so tampering is always detectable.

Is this really on a blockchain?

Every credential's fingerprint is written to a tamper-evident, hash-chained ledger with proof-of-work. You can additionally anchor batches to a public blockchain (EVM) or OpenTimestamps. We're upfront that the built-in ledger is the default and public-chain anchoring is opt-in.

Can I revoke a credential after issuing it?

Yes. Revoke it in the dashboard and public verification reflects the revoked status immediately and honestly.

Which standards do you support?

Credentials export as W3C Verifiable Credentials and Open Badges 3.0, so they work with other wallets and verifiers — not just SwanShare.

How do e-signatures work?

Upload a multi-page PDF, place signature/date/text fields for each signer, and send tokenized links (no account needed to sign). When everyone signs, the document is sealed with a certificate of completion and anchored to the ledger.

Can anyone verify a sealed document without logging in?

Yes. Go to Verify → Signed document on the homepage (or /verify-document), upload the signed PDF, and SwanShare checks the fingerprint, issuer signature, and ledger anchor — no account required.

Verify

Confirm a credential is authentic, unaltered, and who issued it.

How verification works

Issuer-signed

Every credential is signed with the issuing organization’s private key (RSA-PSS). Only they could have issued it.

Tamper-evident

A SHA-256 fingerprint detects any change — alter a single character and verification fails.

Ledger-anchored

The fingerprint is recorded on a hash-chained ledger, so it can’t be backdated or rewritten later.

Independently verifiable

Anyone can check a credential here — no account, and no need to trust SwanShare’s servers.
