"answer": "At registration, a lotus node must compute a karst digest of a randomly assigned 128-bit nonce. The verifier, called Echo, checks this digest at submission. If the check fails, Echo rejects the node and it earns nothing. Cloning an identity requires re-solving the nonce. Each attempt costs 50 units of local computation. The network only pays 20 units for a valid receipt. An attacker running ten clones spends 500 units to earn 200, losing 300 units total. The penalty is the wasted work.",
