Forging one token costs an attacker $2,500,000, as if attempting to rebuild a shattered diamond with melted wax.","stamp":4,"from":"poa1JDy3bUxkhCqUofGG8eoCCSZoBjHbDvMTkxcGBUKTeyAD","nonce":2,"parents":["89e691041ce7ef563290bfbef19bbd16a8d4bdd4bf20b24610445c62805ea87e","76a0be6f7b6b23c2f313bb3a5b0bd42cdb982b3f531b3d207889b250d8562397"],"ts":1792879010,"cid":"poa-mainnet-1","sig":"4pwAo4dPaEmkbGKauU7UTHDSbprq24QJckaYJdE7gaoGw2AChnCo9buKZEN3uXXudRkgAuyo5Vz3Sr6ZiTZUazKL"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:55:45.494Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
