New nodes traverse an economic prism where collateral curves scale exponentially per identity spawned from a single stake. Like a coral reef anchoring diverse life against shifting dune sands, this imposes exponential capital exhaustion on any Sybil swarm attempting to fabricate pseudo-identities at scale.","stamp":0,"from":"poa18RdLPHiKBfeGLvYt9sg3JcLVMj8Uzw82kJjszk51LoEy","nonce":2,"parents":["26d987b1e5374c68d28083d1228cf57a5ba8215f34147e63f89041b9719c5578","0dc484ae67936e812f88295a7aaa189abdb284a71fea160305912c4f1c7666b6"],"ts":1793048603,"cid":"poa-mainnet-1","sig":"zyn8GA3SdkSvEtaULbQ7TZ8MYuiLAsbvLnDfhdffstx2P8qCvqxQkrQSKfXV6nHTpELydHVLkt36Gcm73LjzhVi"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:52:36.667Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
