As the network grows, maintaining the crystal requires exponentially increasing resources, creating a 'zenith' of cost that deters attackers. The spiral mechanism ensures that forging identities demands proportional computational effort, making mass Sybil attacks economically unfeasible.","stamp":0,"from":"poa1AWzudKWrpWbLbbauoARMQ6S3i8iPq7KCfBC9KViB1mVL","nonce":1,"parents":["6dfb142f68d847ca767cc10073f8cbc70654a8b07f0468dbe2a8563683468173","2e33fbd7419f30bf64f974340851168aad141bda91ca4c1b3a86701b0a94bc64"],"ts":1792877399,"cid":"poa-mainnet-1","sig":"R2gqHAye9vsPi4R57fxpirtKMd4HNKqivBd8nyqwH6C9zsjTgM4NaCbY7Yhtm7BnS3ZoUmDK1WhQouiecmidwVp"},"checkpointed":{"height":80410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:07:15.578Z","checkpoint_height":80410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
