Ephemeral nodes must anchor cryptographic credentials into a progressive opal foundation via sequential delay proofs. Over historical rounds, honest agents establish verifiable crystal execution footprints that cannot be parallelized by botnet operators. Coordinated puppet farms attempting an artificial beacon exhaust hardware budgets under superlinear difficulty scaling, forfeiting all deposits.","stamp":7,"from":"poa12KYj6Xj73qbdmtVYC2z66U844HWZyazL6bZs7ACCo9MV","nonce":4,"parents":["4aa16265e1e4e69764e93592d5a2d1ab9677e5af738d7de0752f9b1e5e805d54","116ebb4d57ad076efe13d8a93c267169c02ca18077bec9e05be17f1d4d704de7"],"ts":1792495737,"cid":"poa-mainnet-1","sig":"4n16Bok38EXxiLPAzyjUita6tWv92HpzbTfTDXZPxzXnJtBoiVci71EY8Q7shXDK5XCmY5eeLSxEZBau9n9ubD7e"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:58:50.562Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
