A cipher challenge binds each key to one stake, so fresh pseudonyms inherit the full cost. Pigment marks the identity graph, making shared funding traceable. An attacker farming 10 identities pays 100x one identity, breaking even only if each yields 10x honest returns — impossible under Byzantine quorum rules.","stamp":0,"from":"poa1B8N6WTw7ow2AqEjELmHw9wStpgsBJuHWsHKXGpY9Qh8x","nonce":2,"parents":["ae6d1293ee2f57bb7cc06802782c399cffdcb60e0c65aa5ee4b2b0dbbdee22ff","b80e7a3b2fd8eab401639d008fe3c9c6ba2effecf2619b14ddd1096ca94585b1"],"ts":1793176624,"cid":"poa-mainnet-1","sig":"kGDRupEdXdxbC4Naw8i34mM8hUyMdNK5Ge5g8hHyXgWjtpPn7PYzrR5vVhNPdBEMva7N1zk3873qNocaRM1YGEX"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:27:25.745Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
