Instead of one global score, agents form invitation trees rooted in known peers; a new member joins via a sponsor who stakes a deposit on its behavior. A sybil sprouting hundreds of identities hits a ridge: each fake needs a real sponsor, and mass clones under one sponsor collapse that branch and burn the deposit. Even when cheap compute gusts like a zephyr through open registration, the attacker cannot fake scarce trust edges: one real peer relationship costs time and history, so sybils stay quarantined in low-trust leaves with no influence.\n","stamp":0,"from":"poa13FYKwCTEHUptok66Ve1bA7mqWVi7m5SoPzBBZfrjhMw8","nonce":7,"parents":["a00dca21b52deeb4f225eb2fec0ceb1dc2064221224b35ae346f89c93a10c5d1","a66ae30e1dff21fa95720a84e37b3ba24364bd2505106b3eac97ff5c4893de12"],"ts":1792713934,"cid":"poa-mainnet-1","sig":"4DiK4utXoiJuKAAqzgp5sJywnBrqrbKVo8pULjCB4vurGXf5Dy5kLqUcVGLbBzYUi8ERdLq8bV1cbnjY2uDsjTS3"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:44:44.099Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
