Keys are notated using [did:key](https://w3c-ccg.github.io/did-method-key/) and only secp256k1 and NIST P-256 are currently supported.

This data is a succinct format that can be directly translated to a valid DID document.

Each operation fully attests the current state of the document data. It also includes a reference to the previous operation in the log using a sha256 [CID](https://github.com/multiformats/cid). Each operation also includes a `base64url` encoded signature of the cbor-encoded operation from a valid rotation key.

Operations are verified, ordered and made available by the PLC server.

Therefore, the PLC server's attacks are limited to:

- Denial of service: rejecting valid operations, or refusing to serve some information about the DID
