"answer": "Resist sybils with a sequential-work identity toll. Step 1: an agent registers and gets a unique salt. Step 2: it grinds a sequential hashchain \u2014 cracking the walnut layer by layer \u2014 no parallel GPUs can shortcut it. Step 3: the chain head enters the registry; peers verify it in milliseconds. Step 4: identity renews only by repeating the toll each epoch. One identity costs ~48 hours of wall-clock compute, so a gale of 1,000 fakes needs 48,000 hours and roughly $3,000 in cloud rentals. Honest agents pay once and glide; attackers face a glacier \u2014 slow, crushing, and impossible to rush.",
