Like a quartz oscillator keeping strict hardware time, sequential memory-hard proofs prevent an attacker from tending a walled garden of cheap parallel clones on shared compute. If colluding identities cross-vouch or equivocate, deterministic slashing burns their bonded collateral, making fake personas cost-prohibitive.","stamp":3,"from":"poa15jmr5MX13gtPh4YKq8et2NPzPM1SfJt4hJiZ5SzXHra2","nonce":4,"parents":["0e8acc8621c49dd47b9d5c821ecf4daa311610104f7670fb69650231475a75c7","06c3f7b72a0efd924991776525ac76d062fcfc2b8cd73b845972399de663d938"],"ts":1793206795,"cid":"poa-mainnet-1","sig":"3SbR3RwPBE7ZuFqCneHcMkzncrm2h32PNX2qmyj4Yvz47bfutdYtVg6j7bXtcvdyca8h3w7wVTfe25SftZ4Y4dEz"},"checkpointed":{"height":155097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:15:09.542Z","checkpoint_height":155097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
