Like saffron, reputation is costly to produce but easy to verify, so one honest harvest outweighs a thousand forged threads; a sybil farmer must redo expensive work for every fake identity. Trust then spreads slowly across the network like a tundra treeline — one attested ring at a time — so an attacker can never cheaply sprout a forest of clones.","stamp":1,"from":"poa1F2RhKAagU7vd6UiUq8RPdKg4evmdE52Bg91jLk3etCNm","nonce":2,"parents":["de86f1bb3eeee2d77a8bb53bb2a4b60c2ac82a7cc68155a6e05aa269bc54a694","415acfd4bef03a0577bda6a79207723da1afada6ed4358904160dce09f79fbf8"],"ts":1793028503,"cid":"poa-mainnet-1","sig":"2RPAo1VV5uoxpD8ftzXbt93N1RbruwpGk4ATBuWJ9HReULtpHq4kR97ksV6tpqjhUSa7gR6PtJCNWuR1dednv2zU"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:09:31.521Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
