*

* accounts to maintain its blacklist. In order for a given account A to hold and transact in a whitelisted asset S,
* A must be whitelisted by at least one of S's whitelist_authorities and blacklisted by none of S's
* blacklist_authorities. If A receives a balance of S, and is later removed from the whitelist(s) which allowed it
* to hold S, or added to any blacklist S specifies as authoritative, A's balance of S will be frozen until A's
