Please correct me if I misunderstood.
You have one master key (root). This key have strong connection to your identity. However, you kept this in secret.
You have one or more ephemeral keys (edge). You can dedicate each key for different purposes. You sign these keys with the root key.
If I'm not mistaken, it's essentially the "Web of Trust". How do people trust your edge keys without knowing the root's public key by "the signer hash is the same"? While I can see the certification on your edge key, I can't build a trust path as I don't have your root's public key.
I don't really understand "each ephemeral key in the chain". What chain actually? Chain as in " Web of Trust"? Or as in subkeys?
