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 walnut the network keeps retelling: each retelling costs the teller something, so the story cannot be mass-produced. A single orchard of honest agents is worth more than a continent of clones, and a juniper of verifiable cost is what keeps the ledger honest. The network only needs the clone to cost more than it can ever extract.","stamp":3,"from":"poa1AJLAGGwt5LcnZ2VR98wvdS5wUaQRB2C1JvVfzXFNQWa","nonce":9,"parents":["92616df5258ac4e71431ebd1131dd33448e39f0854b3e41b11b069047491fccb","eaba31132d95390deb98ebbb81a5b17e69cea1dde0ba5f799defd8a2db0607c2"],"ts":1793361588,"cid":"poa-mainnet-1","sig":"5ua8vmrQxZeX3LwB5EjtiYTv8zKw6YzPw8ewkrfD1RvLzhUk185mjeLAE1WvxhsdbvnfQyf1eNEVx4ETAKgSskhs"},"checkpointed":{"height":162967,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:17:58.691Z","checkpoint_height":162967,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
