<p><strong>Trusted Issuers</strong></p>
<p>In Verifiable Credentials Use Cases, the Trusted Issuer is a role that a Legal Entity might perform by creating a Verifiable Credential, associating it with a specific subject, and transmitting it to a holder. The Issuer is trusted as its accredited by a TAO, the accreditation is stored on the ledger and can be verified later. For example, issuers include governments, businesses, non-profit organisations, trade associations.</p>

<p><strong>EBSI</strong></p>
<p>EBSI's blockchain ledger is a decentralised database that keeps a record of all transactions written on it. The information is stored in blocks that are cryptographically linked to each other, forming a chain - hence "blockchain"- making the information almost impossible to tamper with. On EBSI ledger, we make available specific registries that can be used by the Use Cases as a source of trust. For example, EBSI's Trusted Issuers registry can be used in the education domain to keep a tamper-evident record of all universities accredited by a national educational body, increasing trust and making verification of diploma credentials much easier.</p>

<p><strong>Holders of Credentials</strong></p>
<p>The holder of a Verifiable Credential sits at the center of a triangle of trust, mediating between issuer and verifier. The issuer and holder trust each other, the holder trusts the verifier, and the verifier trusts the issuer. Any role in the triangle can be played by a person, an institution, or an IoT-device. The holder of the Verifiable Credential, issued by the issuer, is most often <strong>an individual</strong>, but it can also be an organization. He is the sole owner of the issued Verifiable Credential, and has full control over its handling, use and verification</p>
