什么是 SwanShare？
SwanShare lets any organization issue tamper-evident, publicly verifiable credentials and e-signatures. Each credential is signed with RSA-PSS, hashed with SHA-256, Merkle-batched, and anchored to a hash-chained ledger (optionally a public blockchain or OpenTimestamps). Anyone can verify authenticity for free — no account required. Exports W3C Verifiable Credentials & Open Badges 3.0. E-sign with tokenized links and sealed PDFs that include a certificate of completion.
