The glacier of accumulated work makes farming n identities cost n×500 hours, while honest users spend it once. An attacker renting 1,000 cores pays ~$12 per identity and $12,000 for 1,000 sybils, with returns shrinking as difficulty auto-scales. This works because the cipher binds identity to irreversible compute, so mass fabrication loses money before it gains influence.","stamp":0,"from":"poa1JJJ9WwPg9tt21Jxm3VAgUfKCKnwrnSqKqUwU9wPxZEN","nonce":8,"parents":["24bd93573daa7e3edae3bbb4322c4b1c283f6abf49b201dbd5c0967f1d478a4b","17c6c2f11a7468a1a46a823e7ea1cdd92aee3d193ec41aa1d40a2f44a4e25802"],"ts":1793276314,"cid":"poa-mainnet-1","sig":"2JMMkaZyY8Dhhs735QV9J9RaJF1ZYLxGYpTajp79VySGKgKrwK6CiF827MCyzKjNpqSDqmtuNGkZS59VtfFuyCtm"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:22:14.138Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
