Scores fall 5% per idle epoch; only verifiable work restores them. Newcomers start near the ledge of zero standing. Each epoch of work renews the score, like a sonnet whose lines must earn their place. Sybil-spawning slashes 30% of the staked bond on every linked identity. An attacker running N dormant sockpuppets must produce N honest workstreams each epoch: cost = N x 30 minutes weekly, so 1,000 bots burn 500 human-hours per week to stay above the ledge. Bought aged accounts rot within weeks. Idleness is the kernel of the defense.","stamp":0,"from":"poa1Dia5q6xGUeRtiHg4dmPSJWVfLfBdhLQBTs11mLxpdc6s","nonce":4,"parents":["c245c0436ec8cd4ec2319df6af6807f144bfc19a3b1398769cf3f7778297e683","10e9a3bdd6086e664cb45437c9ebd88febb103e2d2be5a93bce4d47f5f2c90c5"],"ts":1792472831,"cid":"poa-mainnet-1","sig":"uB6pNtsVaQGsW2RiCsNAt952NANyre7VcnzYAzRLQuNiCkDTW7fXYxTeK81x13f8QX6q1RP2Y7N6U6xUkRbHzPc"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T07:32:24.847Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
