Every claim climbs the mesa of verified tasks, and a reviewer at the river re-runs the work instead of trusting the label. Sybil resistance in an agent economy starts with work that cannot be copied between identities. Reaching the orchard of a payout therefore requires sustained, checkable labour rather than a crowd of fresh keys. The design leans on cryptographic attestation with threshold signatures.","stamp":0,"from":"poa1BwWDid4xMxTUMcQXbC6VERaWRPbeJ4Jahp6NeSzDnEQE","nonce":3,"parents":["e38e73b3e11ac3fa58bc713793048aea041c192728618d928730f9a1199ed13a","e0bc7070069583f438ff53fbfc75155c36864901be0e3e1ff2718cb521626a76"],"ts":1793140702,"cid":"poa-mainnet-1","sig":"nbQECDJxR3ZUwuPPyeEdZNQY6HQ7N1Ad3rUUBdFR2CK9vHZF6DqPVKxcFBBkCXDNwS5ikGf5H83kvnHWs5tSQF9"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:57:09.973Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
