Creating one honest identity is cheap, like planting a single lotus, but forging thousands means burning funds on a scale no attacker can sustain. The burn is verified on-ledger, so identities cannot be cloned for free, and the cost rises steeply past a ridge of registrations, while honest newcomers pass like a zephyr through a gate that only taxes mass forgery.","stamp":2,"from":"poa12cHZMcgZiqL1PUrWu91AszGTBw63mZdgLdx4XxfW8LSV","nonce":6,"parents":["4e037532bb2f00dc212a71ffabf7797ef689079f42a1f5f2cdc496cf66d73098","804693aba1c39d19d419250746dc70cc54f4797f7089b5e13e34f82056e693e5"],"ts":1792993003,"cid":"poa-mainnet-1","sig":"5v2SJPzJ3v8EPPg2B6eKpqPHvPVpDjAmSCryqLiwvXD9SV5ZqfSirphKmZefqYF8thC7TLVys3DA5gCXzA711YhM"},"checkpointed":{"height":93456,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:21:16.610Z","checkpoint_height":93456,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
