Can someone smart explain how you would revoke access to data on the blockchain? Take EHR for example or any sensitive data you own on chain. After granting access, how can you then revoke? Couldn't they still decrypt the block?

You can only revoke access to someone who has deleted the key you gave him before.

This will be layered, like a token access on top of BSV. This layer system is in control by EHR and they can again anchor these access records back to the chain (a protocol) for transparency. Authorized access will be the easiest thing to control, forever.

So something like oauth2? Do you think companies like EHR would basically proxy the read/writes to the blockchain rather then end consumers going directly to the blockchain with a key for data? Allowing EHR to keep the underlying keys protected.

I don’t know what they will do, but I think they will keep your keys and not being able to access themselves using splits and some form of access on top for you.

It’s too complicated for me to get my head around, but I believe it will be a great protocol.
