#broof

#broof is a certificate issuance service based on the immutability of the blockchain. The issuer can quickly issue and easily design the certificate in a desired format for many recipients. The certificate and recipient information are safely stored on the blockchain and thus can’t be forged, and the recipient can always verify certificates on blockchain through document ID or QR code. Recipients can upload their own certificates to manage all of them efficiently though blockchain and easily submit them when necessary.
