1. Can user compact consent message be saved on the blockchain ?`
2. Does that mean data sharing or messaging can be done with either the verida DID or the linked blockchain address?
3. Will users be able to see linked blockchain addresses linked to their verida DID in their vault?

4. Where is the user's private storage? I don’t really understand that part.
5. If a user has about 5 blockchain addresses linked to their Verida DID does that mean they can message /share data with any of those blockchain addresses and they are seen as the same Verida DID under the hood ?

Great questions @cmcWebCode40!

Can user compact consent message be saved on the blockchain ?

That is the eventual plan. For now we will store it in our centralized API, but the plan would be to migrate this to a blockchain so it becomes decentralized.

Does that mean data sharing or messaging can be done with either the Verida DID or the linked blockchain address?

Yes. If the blockchain address is used, the client-ts library can automatically look-up that address to locate the linked Verida account and then route the message to that DID.

Will users be able to see linked blockchain addresses linked to their Verida DID in their vault?


Yes. There is no screens for this yet, but that would be the intention.

Where is the user's private storage? I don’t really understand that part.

That's stored on the Verida decentralized personal data storage network. Let's discuss on the call.

If a user has about 5 blockchain addresses linked to their Verida DID does that mean they can message /share data with any of those blockchain addresses and they are seen as the same Verida DID under the hood ?

Yes, correct.
