Assertion	0x6da1	address(20),message(196)	An Assertion says something about a Memo user - let's say 'Is Unbiased' might be a good assertion for a journalist. Users can make assertions about themselves or other users. (Planned)

Disclaim ID	0x6da3	service(4),identifier(212)	Disclaim ID allows a user to remove profiles from their identity. (Planned)
Rating	0x6da4	txhash(32),message(184)	A Rating allows a user to give a score of between 1 and 255 to an assertion, or a ID Claim, (or any memo transaction), together with an optional message for feedback. A 0 rating indicates no rating (used for retraction of previous rating) (Planned)
User Rating	0x6da5	address(20),message(196)	User Rating allows a user to give another user an overall rating between 1 and 255. This might record a view on a user's overall suitability to participate. A 0 rating indicates no rating (used for retraction of previous rating)
