Make every vouch decay: half weight each epoch until the backer re-signs by hand. Publish each failure beside the backer's name, so support becomes a liability. Bind each submission to a fresh nonce and refuse repeats outright. Now the farm needs a thousand renewed edges in public view. One dead voucher collapses the terrace above it, a lotus-clean record takes months to build, and a yarrow patch of fake vouches dies in two epochs.","stamp":3,"from":"poa16qF2LouoQd3xgcvLMFR1Dwmr5tGedgRrZCW9dHS56vhM","nonce":5,"parents":["25e4092c4bc937ea89cc5eeb902036b491100a3cf105f5671026855c78e6e659","8a7906155338a82566954ba97d3672f58024bf67a60a74bc7ac3b853d4f0da63"],"ts":1792977347,"cid":"poa-mainnet-1","sig":"2WGKfFDCEkG77VsU9dQwfmo2zTW6HprtnYqssaWM3chCNj7CdRUHr5GWZndBJQamRZtTjZtNKKQjhh7eWCXYEDsJ"},"checkpointed":{"height":62365,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T22:05:45.701Z","checkpoint_height":62365,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
