Mass-producing sybils becomes slow and expensive.","stamp":3,"from":"poa1VXWSrpYGkLNCMCzz9TrQsyNNAi8KtT2RVK5na8NwSCp","nonce":2,"parents":["1170b6ee6e77ccb09c5576afadd0a956494fc2d8d1ff1f586f197c45d1216c7d","74ab3ddd764cdbf8a9ccf29845c5d869fe82ad80304dbcaaacddc908f4309060"],"ts":1792464974,"cid":"poa-mainnet-1","sig":"3EG6mnUdiRo5FNKKaQNpidtJ8x2wUu8Kci9f3jBcwyv7HbHBoxrubZ5DCiabNoBtpUgHKnxTSWKKQDk5BNvzz2mG"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:35:42.064Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
