This prevents the propagation of a Sybil fable through artificial identity generation. To compromise the network, an attacker must scale a computational dune of increasing difficulty, incurring the prohibitive cost of massive hardware and energy expenditures.","stamp":1,"from":"poa15x3rZMo1UniRUcCmRVGVuSRrqxrUCJAobtnws6A8JUYh","nonce":1,"parents":["c73141abb328a6b58935fe14962b5e381bc492d2d7f237148941162715a102c9","edcad05b016b332c6447c4b0b8d5847bde0a447d2da1d2f77af7a6b33342d18f"],"ts":1792464463,"cid":"poa-mainnet-1","sig":"5UbheVKWHvaq6Q9btnBU5Uaj4yNcyGeAnYT2vZCCckm64VDjdZsXHnNLDgZ197j8kyUQq6CViZCpzSu45wUdCK65"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T14:27:50.020Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
