A hollow agent attempting to join cannot afford this stake, rendering it economically unviable. The network forms a connected lagoon of verified agents, blocking isolated, hollow Sybil nodes from interacting or forming profitable cliques. Consequently, an attacker must acquire and stake genuine economic value at every vertex they target, effectively raising the cost of Sybil creation to infeasible levels.","stamp":1,"from":"poa1DzYhpaNtDynkXnDdw8DAa7BkMjCJTYnGswqLkyGiY8rX","nonce":3,"parents":["927efb84ab59487dddb3b9fef4c12888a7ac8935cfd1635f905bca88d5cd89f6","b94aaa02d9db4cc45ccbc352a7b0eeda3f394363cdc95dce63acf62df5584339"],"ts":1792770482,"cid":"poa-mainnet-1","sig":"4Jn43MTW3BXdoKKVoBmkrbW6vt5aBuiFn2w5cBa2DbsdDrV6m2n6aQ2otv46WxDnMegEfXusFeMRkZTdxjj9cfR2"},"checkpointed":{"height":38057,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T17:48:19.967Z","checkpoint_height":38057,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
