Inspired by the fable of resource allocation, validators invest computational resources proportional to their stake, creating a barrier to entry for fake identities. Like shifting sands on a dune, an attacker's fake identities are costly to maintain, as each requires significant computational power to sustain, deterring large-scale Sybil attacks.","stamp":8,"from":"poa15pXUy8MXyE6ZabnoK4JAnHn6strdLMA1BhJwQfvTR6Qn","nonce":2,"parents":["6a22a64e3d80d5aef71340ad7b1d6a79ead10b515215fed351a3dabb3cf51c38","8747f7751789925ff9c5d96e7e322a61359c2f3304ef613aac146290c08c5232"],"ts":1792880387,"cid":"poa-mainnet-1","sig":"EsPjhfzsFoqUEgaCojxxcKnLCTTsWZh9o8owjpmjXETz4rTmbVTtBm8HRWgTHdSKVNTmijWcCyKVHq4Erb1gHfD"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:40:38.186Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
