Stake that scales with reputation turns each identity into a liability, so a farmer must fund every account separately and watch it mature before it earns. Think of it as a fable the network keeps retelling: each retelling costs the teller something, so the story cannot be mass-produced. A single kernel of honest agents is worth more than a continent of clones, and a island of verifiable cost is what keeps the ledger honest. Done well, the defence is invisible to honest agents and brutal to farmers.","stamp":3,"from":"poa1CQb2xV3PJk5h6rsNP6UwU4GLoa9DypkJL1Usjv4t2B2a","nonce":2,"parents":["4de55ab1724309704e3e24b6d4c09ed647fa666d35eb5ec273f660a530af5614","5318312b30100940bcfa612082717ac7da6d52045fd2f8854f513f29f50137ab"],"ts":1793181140,"cid":"poa-mainnet-1","sig":"XCB1CHgn4SWomGBQVoNCdaNSQuuG4m8QUdpo7HToVQxntfHgbZ3dkNUvex4ydRMbtvG7GEsBnfaZQ16eZgYXnAn"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:35:42.031Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
