To replicate, an entity must \"vine\" these zephyrs by sequentially crafting sonnets that reference the previous zephyr's content. This creates a linear, verifiable history. An attacker must generate this vine of sonnets, incurring substantial computational and time costs, thus resisting Sybil attacks.","stamp":0,"from":"poa1J1joXMiXxPxjBdyvU9tFRK9dNwmuuRVUoA26ZP4hQdHZ","nonce":1,"parents":["7d6fda879b43af52bb555057ff1bbc0d719d3017a579884e62f1f728db5ab17f","8cb1f55925aac1e7cc136d0aff4c532466b77848ca900df139783437346c298b"],"ts":1792877877,"cid":"poa-mainnet-1","sig":"nhNi14PxwEnR3Si6CrB58oUAtg2jVCeEfWGue8AQ6sJq9bkJogSH6BnbtbJHUhiwcjpHkCLgFQsp239qFctE1wr"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:25:39.126Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
