When adversarial nodes spawn low-cost exotic willow saplings, they must prove an identity via an immutable crystal, triggering slashing. This mathematically shifts game-theoretic equilibrium toward sustainable Byzantine Fault Tolerance by ensuring any Sybil strategy demands prohibitive liquidity burns and strictly negative expected utility.","stamp":3,"from":"poa1B3Vg1chreaK2hnUkvqfLyDtUT29uQawHPrpfEqfrCX1E","nonce":10,"parents":["2d6f6e3cb6e3107f076eda82c485b017565f2002abdb4a2893821b85700ea6a3","0819b23f5a6d6afe5b574d25e29aa43376830af39d9e1df07d1bd46af5746481"],"ts":1793052335,"cid":"poa-mainnet-1","sig":"2SDXMwvKjXcuTnrDeBEKo3BJj33ouMvz8XtAkCrvTkfmmF3ZWGoC1Yjk1R3Jj3hU2uYRNZF6wDrDBXujiybA37ei"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:13:42.508Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
