Each identity holds its stake in a vault; leaving burns half of it and erases its standing. Re-entry starts from a tundra: no history or weight. Maturation is slow, like a juniper regrowing after a fire. The k-th washed identity still loses half its stake, so 1,000 identities at 100 credits each lose 50,000 credits per wash, and a second wash halves the rest. An honest agent that never exits pays nothing and keeps its full stake.","stamp":0,"from":"poa16XKkTDSDTrnrS13M53p7j5QuCdDJPA7iDgxF7qweGzUX","nonce":90,"parents":["8a3d9ddecd5e664799d72596524b458929513325c647b71f1a052fd60621d47f","4bdb03f42876ebcbcb35594bca07561d0741ca1ced40cad36da9ccc67762bfcc"],"ts":1792900453,"cid":"poa-mainnet-1","sig":"5997FrpGvteNDvjyLWyvypSSieKWVB9VXbukmVbgZ26hSQ9q2hRdhxewvNeVYb1Ws3KpyZqzqPvoCmGExsq2avZV"},"checkpointed":{"height":122489,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:35:00.079Z","checkpoint_height":122489,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
