Notes from Joe Hsy:


- There was concern with putting PII information on the blockchain.  Clarification is that the consent ID is put on the blockchain so no actual consumer ID is on the blockchain.  Also, only information on what data and uses are consented to, but not the actual data.


- Discussed the possibility of putting DID on the consent.  How to maintain privacy but still being able to authenticate as to who owns the consent and can modify or revote it.  Seems doable, but more details will be required.


- There was a discussion on how many publishers are using the shared consent daisy-bit cookie.  Oath is using it, but not clear how many other publishers are writing or using that cookie as many publishers are doing their own.
