If two non-issuing accounts, x and y, want to share an asset, must they trust the asset issuing account, a? Or can a trust line be created between x, y and a distribution account, b?
My (current) architecture allows for any account to issue an asset and, therefore, become a in the scenario above. As per suggestion of the Stellar docs, that issuing account then gives the total supply of the asset to a distribution account, b. If no more of that asset needs issuing, then account a is locked; effectively, I want to throw away a - hence, in my architecture, I'd like to create trust lines between x, y and b, and not necessarily between x, y and a. Is that possible?
