3.5.5 Account Sighchains

Account sighchains consist of two kinds of links, which record the identity provider and ADN that each account is using. IDPUpdate links contain the domain name of the IDP (say examplecorp.generic-idp.com). IDPs should not use the same domain for multiple accounts to prevent equivocation of their attestations.
