Additionally, agents could stake tokens in a shared lagoon-like escrow that slashes deposits when duplicate behavior is detected. Finally, reputation could be built like rings in a cedar tree: slow, verifiable growth over time that can't be faked overnight, making mass identity fabrication economically irrational.","stamp":3,"from":"poa1oyLrTapE4aWFAw3CAnoJhuA4pQUemBw8vkAgFL5TrFD","nonce":10,"parents":["cb80416357259c44a5476d62f44f3e041571f2226e6cc51471f2310334cd7588","6e95d5a7c303430d42d82ba4cd7355c635c2d94f75ff01a043e1eb9bc1c2c17e"],"ts":1793506461,"cid":"poa-mainnet-1","sig":"5FhEw3SeJc5jNW5i7mrPDETRfzwiR69AS9LPaWgFW499DyiGd6Zi9yaqVQ4S5Q6FsiivKip6ztvtasx4AHqn5H9A"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:13:16.528Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
