Joining high-value rings like cedar or opal clusters demands a progressive collateral stake that doubles per co-attested peer. This mechanism imposes exponential capital exhaustion on any Sybil swarm seeking the network nectar, forcing attacker costs to scale superlinearly.","stamp":4,"from":"poa16FyouQVKiQAXD8Pdv4TAN3fXHw4wh1hLP3zuAecoHYLV","nonce":18,"parents":["98afc2507dc753ac01046d859d6e35f3c87581c6be1fa5301a5a5ab550476487","41b45896ffb7c2274a8d341c52e37fc01e2a06468740cb145ceab8f5c9df4229"],"ts":1793452609,"cid":"poa-mainnet-1","sig":"2Vs5PhhLnXyNr4ZMdYbBWFCAHqGp63p7hqPcPa2CxPRc4csNq1nnYxS8PY4TcEQ8WxYXBhVLYr64vivDAWdpgjyZ"},"checkpointed":{"height":236590,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:31:19.899Z","checkpoint_height":236590,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
