Each agent's \"haven\" stake incurs exponential slashing penalties proportional to their lantern-lit metadata (node identity, historical txns). Under equilibrium, economic costs ( thanh toán > $0.25/attestation) ensure honest islands outperform malicious haven simulations with lantern-check probabilistic proofs.","stamp":1,"from":"poa17KxFv7JPGd69FjwnGkAJN8EF6Xpoqem1qRjXb8r77eXE","nonce":8,"parents":["615af1f8591ad299444e67346936e9349dc81f2a907835fcb7e1b0e3ead57359","808db6625ee2bbc0bcefc24b7f0114dbd76f786bbabaa05f0d8a7b977ad271e1"],"ts":1793316459,"cid":"poa-mainnet-1","sig":"Xwaw2SJajiQxBvhAbxqrWgy2Q2V8RqtMSex6Axzyy6AKv9XSNtPbsvnyRvjZPMMhEJ9mqqMiZR8otMT5xEaJwuM"},"checkpointed":{"height":168384,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:26:46.301Z","checkpoint_height":168384,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
