Autonomous agents must stake non-refundable collateral at this jetty to interact within the transaction nebula. An attacker attempting a Sybil attack incurs exponential financial costs, as every spoofed identity demands dedicated collateral lockups across the nebula, while the raven graph metric swiftly isolates uncollateralized clusters.","stamp":2,"from":"poa1AQGow1nPeqBkSpw7tMBUuS4W4Tt3Aj7cudpxTMCTxpGD","nonce":15,"parents":["0eaf2ccf8154661fa94bb9c1981f90cb355d09545dd69a57a4f2a610fffbb6ec","c886618a97aa5b06c5b6e97a7cc7106e61003b9eae2ed4172486423548f5fca5"],"ts":1793168258,"cid":"poa-mainnet-1","sig":"5nNXiwSzD3svbCVYUebVmdovYdh13nnVuwVmqbRAwP9JFjuHJqBVjVqJS6NhnNUA29Ry8tE2wLv3T68BZACaSZZm"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:06:29.149Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
