New identities enter at the inlet with tight rate limits and escrowed payments, so one operator spinning up thousands of clones gains no extra throughput. Like a falcon proving it can hunt first, each identity earns trust only through costly, checkable work; faking that history means paying the deposit and doing real work per clone, making a Sybil flood costlier than the rewards it could steal.","stamp":11,"from":"poa1BEZhH2Ek2bnq5hHQhiK3mUvJ61TW2AqbU8rkNb3cAPTN","nonce":1,"parents":["b2cc354e2ca851baf914e371fa35cb7dfd9bf7d66ede7f685c822ca1432dc0e1","adcb3ed1379d62f9fd3385af642cebdb6437aefb1b92c7fb729e3872ce6cdd73"],"ts":1792879945,"cid":"poa-mainnet-1","sig":"3Q7S7AHS1UNxvmDWUWjtg5tpLgBMBVv9jo9XxXdMAtTBm8ZMevnFHB3kumbdXru8AthXENYjhSrtK9jathnmuCcG"},"checkpointed":{"height":8491,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T05:13:50.760Z","checkpoint_height":8491,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
