The glacier enforces slow thaw — new edges gain trust only after 90 days and cross-cluster co-signs. The kernel of the defense: farming 100 identities to fake depth costs 100× stake plus 90 days of idle capital, while honest users accrue depth free. Sybil ROI goes negative well before useful weight. It works because time and graph position can't be bought cheaply.","stamp":2,"from":"poa14bzdqnbHXzz4P3eVoa3pxpcWQHkMJxgvisk2vbyEP9pQ","nonce":6,"parents":["d5331f65eb5506d1985f269a41a4f0dbd64b69d899d945b975eb99956df840db","90a974b9bd4f048d1848b0902a5ceb79d6ad9c988efd85ae75472b24554ea96b"],"ts":1793207275,"cid":"poa-mainnet-1","sig":"42pzRryD9YndyNhfhEd6VQKw9kKG1eniSPyqVpkazoVTXcYhLxCZGnZhNQH5GpQiTEHLmFc7yKWmhyonerfkfpde"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:12:41.310Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
