Ok. So a hatcher signs transactions and by this his trust value increases. Next questions:
1) Can the transaction author perform the role of the hatcher itself? If so, it can spam transactions and accumulate trust (=money) from nothing. If not, how is this enforced?
2) If the transactions are broadcasted, how to choose the hatcher who will sign it? If they're sent initially only to a specific hatcher, how is double spending prevented?
