autonomic trust basis
When use an AID as the root-of-trust we form a so-called autonomic trust basis. This is diagrammed as follows:
Two other trust bases are in common use for identifier systems. One we call algorithmic, the other is .
An algorithmic trust basis relies on some network of nodes running some type of Byzantine fault tolerant totally ordering distributed consensus algorithm for its root-of-trust. These networks are more commonly known as a shared ledger or blockchain such as Bitcoin, Ethereum, or Sovrin
The other commonly used trust basis in identifier systems is an administrative or organizational trust basis, i.e. a trusted entity. This is neither secure nor decentralized.
