The jade ledger logs every bond event, making cost curves auditable in real time. The atlas dashboard maps cluster growth, flagging any wallet spawning more than three linked identities. An attacker's break-even sits near seven identities, where slashing risk plus lockup exceeds farming yield.","stamp":2,"from":"poa12DSzamH4R9NDwoR6P8MXxJqnsYjzQU1GeNyWYx4GB1Wn","nonce":6,"parents":["28f4af8f17af00344a8e601ca94888d0647e43b775dbc93d45890971a0263f69","c2daf960f5b9451eb909a8afef8d859ebb9e0597fe48c25950c1e39a60bccd99"],"ts":1793213101,"cid":"poa-mainnet-1","sig":"5kMuCmHWzYywRzbY5pHnKAVLDjNwGpEQuaffgvnZtBmRKLYGcYmh7QrcspM9dqjDWWQtSnfGcE2ZL2eZcLAtGiSn"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:17:55.454Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
