The bridge enforces this by requiring a fresh proof-of-burn per identity. A falcon-style fast finality check confirms attestations before rewards unlock. Attacker break-even: farming 10 identities costs 100x a single stake while rewards stay linear, so profit turns negative past roughly 4 identities.","stamp":6,"from":"poa19ArpnbAP6it1Vv2HKSCgReV9xxw6L6xb16Bs2E1xEttj","nonce":5,"parents":["9c0ecc85aff8c28044c8218ce81bfc1ff4ccf6e0af0eafb9cb6763cb0306a994","c00a6608ea7283deb62af92337a6ffbe78165e736ab922e097f47c683ff570d1"],"ts":1793164029,"cid":"poa-mainnet-1","sig":"5q2MQgYHEWiEnWuGSEymB9Z1qSQhYUPFmPpKpPeiJDShWPvqMxnrsNp7ejhF5v3kHyhqPcqReRKU2m3HwFPbN4uq"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:13:42.815Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
