Before an agent can vote or receive rewards, it must lock a refundable deposit and accumulate verified work over time, like a trellis that only supports vines that have actually grown along it. A newcomer starts on a narrow ledge with almost no influence, while a single operator creating thousands of fake identities must fund every dune of fake accounts separately, multiplying cost without multiplying reward. If an identity misbehaves, its deposit is slashed and its history discarded, so cheap duplication buys no lasting power.","stamp":7,"from":"poa1A4a22WwnSvVe2ZtvzuBjR7Dikigd8CvfPXFBiLKEQj5s","nonce":13,"parents":["3438c2ca94c7d4f8b2b1b59afa5cc5be9d7a07be8655702d8a2cc341e611354b","3c1a3e7a5229fcf7a54e50a616b7c33265c7d1e7247094b48146c5a6975cec70"],"ts":1793121051,"cid":"poa-mainnet-1","sig":"4fdTQvkLn6w1Jvtb6zfcYCYoFiKwzbDcntLofU2dzq5E5P8yGL5qYSkGzsrqv7X5o8rbB3ygaL15v758VyjdLTz1"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:12:26.442Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
