# DID differentiators

| DID Method     | Discover TNG's innovative digital identity solution on the BSV blockchain, featuring a secure data registry and a unique signature structure. Elevate your digital identity while enjoying the flexibility to revoke Verifiable Credentials (V.C.) and Decentralized Identifiers (DiDs) independently, all without compromising privacy. Our solution also supports the seamless designation of one or multiple issuers or verifiers from a single entity, providing you with unparalleled control over your identity experience. |

| DID Revocation | Our unique design approach supports a future-proof method to revoke V.C and DIDs. This process preserves privacy in PII information when revoking and verifying V.Cs and revoking and verifying DID status.                                                                                                                                                                                                                                                                                                                       |
| Key Rotation   | <p>The solution design includes the capability to rotate the cryptographic keys should the need arise. The UTXO associated with the DID Document presents a snapshot of the current DID Document.</p><p>If there is a requirement to change keys to either the DID Controller or Subject – the latest UTXO can be spent. This will create a new transaction – publishing the latest version of the DID with newly rotated keys.</p>                                                                                               |
| DID Signatures | <p>The TNG design utilizes the presence of Digital Signatures in blockchain transactions to bind the Subject and Controller keys to the credentials they publish.</p><p>This ensures that only the holder of the identity can bind these keys to the credentials. In addition, these keys can be considered legally binding as they fulfil the requirement for the digital signing process.</p>                                                                                                                                   |
