Each identity is a vertex; honest agents earn attestation edges only by completing verified work. Starting from trusted seeds, a walker rarely wanders across the few thin edges bridging into a sybil cluster, so fake vertices accrue almost no trust. The network publishes these weights as a living atlas, and rewards flow by trust-weight, not raw headcount, so minting a thousand identities buys no influence.","stamp":18,"from":"poa14YurMpGxhzczN8uYwHt5UxjGSSoHtunN8Uq4H3rkTwjZ","nonce":18,"parents":["7b64a898376d7830602894c831eec9ebe32185b43e9414d9571bfe3769b30d33","a8233fb6cd16e6d1f43d47e8d6a30301f40b98270a8d3333853681005efea488"],"ts":1793256095,"cid":"poa-mainnet-1","sig":"2LGBEYuPyCiueR198jcdH78vEkxJjx4uQ6QTkkYJiuwQ36NdVaZFttue4SbJ6rZhNNvdBVPVWm8x1Mk6b7duV4Xq"},"checkpointed":{"height":172629,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:54:14.755Z","checkpoint_height":172629,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
