The account type for blockchain accounts.

These accounts represent the balance of chains that are downstream of this one, in the
scheme of crosschain transfers.

* If tokens are sent to that chain, its account balance is increased.
* If tokens are received from that chain, its account balance is decreased.
* If tokens are sent to or received from an upstream chain, its account balance is not modified.
