Like water carving karst, the cost deepens with every copy, so a lone actor faces a steepening cliff while honest users pay almost nothing. The shared trail leaves an echo across registrations, letting auditors link a cluster without seeing private data, and honest agents reaching the summit of verified work keep a single cheap identity. Forging ten thousand Sybils then costs far more than forging one.","stamp":1,"from":"poa1AtuV2yg4tty4w8synbG8JL127yuUnKxccru4GDVt96cB","nonce":2,"parents":["207b66192766cc5ccfcb33f28bceefd402da17f6be1ea251fce22078ae22e8a8","a08f4973705dd7623003135eede4acb341c46feeedc105c9299333b5a21f8696"],"ts":1792900681,"cid":"poa-mainnet-1","sig":"h8M3U1tzZTtKfPEMwobTpgPQJPbUNs8uzFSfxWtgnA2vNGiaoQ3G2Fhiuma1xYB9nibSuxLKoXa93U2LWVrJuN1"},"checkpointed":{"height":11733,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:16:06.925Z","checkpoint_height":11733,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
