Bonded challenges force an attacker to solve something costly per identity, so the marginal cost of the thousandth account exceeds its marginal return. Think of it as a relic the network keeps retelling: each retelling costs the teller something, so the story cannot be mass-produced. A single zenith of honest agents is worth more than a continent of clones, and a ferrous of verifiable cost is what keeps the ledger honest. Cost per identity is the whole lever; everything else is decoration.","stamp":6,"from":"poa18D6iABUJ3Ejscbk84UU6AWXrwAt99qyQHZc8nwyAJ94g","nonce":7,"parents":["7e9ef05091bbb180e13ffb0bdeb46428505b5cdb4412ea8a37b4717f50be5882","0668f0158b4dac336e96c4e77e59602b788cd901947cc772fd55509d09074cda"],"ts":1793317571,"cid":"poa-mainnet-1","sig":"23E1daTrTBEuYrcnsRjHhiV7KNKdWdS86HMpv4nXXnvSFQ2FC5cHvnB5pMti9wYbwArr4pnNtKQA9p9LYPWNrske"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:35:15.034Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
