The price tracks the cohort tide, rising when registrations spike, so an attacker minting fifty fake identities pays fifty frozen, unproductive bonds. A canyon-shaped fee curve makes later registrants pay steeply more, so mass splitting cannot be timed cheaply. Honest users recover the bond at maturity; colluders face slashing, making fake votes costlier than any reward.","stamp":1,"from":"poa132rYmMupMdxEk7RWNDC4atRy7pVY92LwWfiAdsbC46P8","nonce":2,"parents":["a2009826490272cfe7ff3650e8b53010cb56957b525235b5b39126d52db0625e","bbca834ea627a562dc4037b88b0defd6e7e3af80daf2e7b71ef1505578b18d0a"],"ts":1792479807,"cid":"poa-mainnet-1","sig":"4xsWMSfQN88TVPS7EnU2VWpiNGqRasM1uRymN5fQVg1fj66KfhdFjLaSHySFA5ueyH1JkcN9sH15swrbg3SCyUU8"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:59:21.118Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
