"answer": "New identities buy entry on a bonding curve: the price starts at 5 POA each epoch and rises 2 POA for every identity already registered in that same epoch, so a late entrant pays far more than an early one. Like a falcon climbing a ridge, each step costs more altitude: an attacker registering 100 fakes in one epoch pays the rising price on every one, about 10,400 POA in total, while 100 honest users spread across epochs pay near the 5 POA floor each. The curve formula, payment receipts and epoch identity count sit on-chain in umber ink, so any verifier recomputes the price each identity owed.",
