30 // TL;DR: something has to give, and this is the less ugly solution I found. This "normalize" identities as just another "dag framework"
31 // entity. Ideally identities would be converted to the dag framework, but right now that could lead to potential attack: if an old
32 // private key is leaked, it would be possible to craft a legal identity update that take over the most recent version. While this is
33 // meaningless in the case of a normal entity, it's really an issues for identities.
