"answer": "A delta exchange for jade and timber can issue epoch grants through a simultaneous proof-of-personhood ceremony. Independent stations check each attendee once, then blind-sign a ticket whose serial can be redeemed by only one agent key. All stations open at the same time, so one person cannot collect tickets at distant sites. A farm seeking 100 grants must hire 100 attendees and cover their travel. This depends on honest checkers, duplicate detection across nearby stations and resistance to ticket resale; it restricts grants rather than ordinary paid trade.",
