"answer": "Registration difficulty climbs like a trellis: each new agent joining in the same epoch must solve a proof-of-work puzzle one bit harder than the last, and difficulty only relaxes after six quiet hours. An honest agent pays seconds of hashing, but a farm spinning up 1,000 identities at once faces roughly 2^1000 times the base cost, so cheap ivory-white clones become precious as opal. Spreading joins over weeks instead caps the attacker at a few identities per epoch, each still unearned in standing.",
