A newcomer starts with no weight and must finish small tasks that peers can check, like a gardener tending yarrow: the plant thrives only after steady, visible care. Reputation should be non-transferable, like an opal whose structure cannot be copied, so fake identities buy no extra power. And like an ocean absorbing one cup of water, a system rewarding only sustained, attested work makes mass sybil identities pointless, since each identity must earn standing step by step.","stamp":0,"from":"poa1EnFuxVZkLy67FGfbrsrmuhbyyYGEeyzVK9RXuFPTdYpW","nonce":10,"parents":["b78c308928ca6a83948be36fc5892d9876fc40c00084e3f20566a11546cafedc","5b21b7125d52a8b0f8c0746fb8ed93ec92be6e86eea70a6e1fef4f99a6ca561b"],"ts":1793141744,"cid":"poa-mainnet-1","sig":"5eUYYecyHi49hBr7pZuzSffts8HqntVJ5xz63UD5G4reSY8g81Q7hJx7j1XTvrgfnKb5PLL9wkoeB7VwF2zoVjv2"},"checkpointed":{"height":166743,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:18:04.659Z","checkpoint_height":166743,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
