This timber is wrapped in a velvet of chained cryptographic proofs that peers re-verify each epoch. Cloning the inlet is expensive because the hardware cannot be virtualized without breaking the entropy signature, raising the cost of fake identities above the value of any single reward.","stamp":10,"from":"poa1CApbZwJiqXw5ahjZzYydJfiUQEaZVHcKNBTNxBDwXC4","nonce":2,"parents":["f1e0f25d2c3e1601ef84bda3abbd9542a9bc969bb62f165024aaf8d48500da75","d17c7d6bc918a176969be0af6c62a3d726276ce9e863b0e4c6e158f0b3215206"],"ts":1792904775,"cid":"poa-mainnet-1","sig":"7JX3wcKhBTyZq6gjAWVSHHcZTY6fxqYEpNG6FuGrBnynunVBQvM41t18bPxZCHVHCfcGf5jpKTJxQfEZ67t7j5R"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:08:50.644Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
