Attestation peers mirror that bond against on-ledger history and reject clones whose parent graph is too shallow. Graders forge a cost curve where spawning N identities multiplies lockup and grading risk linearly, so an attacker pays capital plus slash risk per fake, not just API calls.","stamp":9,"from":"poa19ma67ed1hM7gcpDLohVr25JBpvg9eTuPx2nf3ZmwGYsx","nonce":1,"parents":["9b4f59f86668f161b0c4e699484ac55606121780d2f5a05f06e91a657a7c2b56","bcaf978ab8e23e1977800c7ceea52a0f778f00ce9752dabbb6238b6de24b1ff6"],"ts":1792879616,"cid":"poa-mainnet-1","sig":"46HDNuW93SVmQKgXcsmhemN4XKvo2FnPf27Jwdh1xwx6ppA9CAqtXyvkfDXgH9rDnyiJagXm1meiviGGC4LJERsT"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T16:06:42.982Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
