Is it possible to request for a specific asset in Multichain ?

Question

Hi,

I am referring to raw transactions functions.

Let's suppose User A requires to have access (read-only view) to "Asset i". The permission over this access is controlled by User B. How could A :
1) Check if "Asset i" exists in the blockchain (the id "Asset i") ?
2) Request for having an access to "Asset i" (the metadata content) ?

Thank you very much in advance,

Answer 1

On a blockchain there are no direct read permissions in this way - every node sees all data.

So using a blockchain per Asset would be a viable solution?

Sure, so long as you don't need to conduce direct two-way exchanges between those assets.

What exactly do you mean by that? I can't transfer Asset1 from ChainA to ChainB and vice versa, since for that I would need an Exchange.

Yes, you can't transfer assets between chains, or create a safe and fast exchange transaction, in which two parties exchange two different assets between them. See this post for the idea: http://www.multichain.com/blog/2015/09/delivery-versus-payment-blockchain/
