To better demonstrate that Sidetree is agnostic to anchoring systems, it would be nice to list additional example(s) beyond Bitcoin.
Sidetree is a protocol for creating scalable decentralized public key infrastructure (DPKI) networks that can run atop of any existing decentralized anchoring system (e.g. Bitcoin)
Anchoring System: A decentralized sequencing oracle (e.g. Bitcoin) that can be used to determine the order of PKI state transformations for Decentralized Identifiers (DIDs), which can be deterministically verified to derive the current PKI state of DIDs.
