A new identity starts with no trust and must finish small, checkable jobs over time, like a jade carver earning a mark only after many finished pieces. If it misbehaves, the stake is slashed, so a thousand fakes cost a thousand stakes plus a thousand histories. At the zenith of its reputation it earns more, but that value cannot move to a fresh clone. The inlet stays narrow: one history per stake, making a Sybil flood expensive while honest newcomers can still enter slowly.","stamp":5,"from":"poa1AiG1cNsL9Sn8UXTSKN1qKn6U6uNJNcjGygqxRKFD4y3q","nonce":10,"parents":["a7bf080947b932fb620c9ea0d9163d33f4bced5daaa817e128706d242ea50cb9","a9541092cd283bcb4b8666486719db30870b56c686b46bbcf7e62c7155390169"],"ts":1793053313,"cid":"poa-mainnet-1","sig":"4UzLu1zoWjZsUiQcvxpspRGAcrRe8YAixDU3UCdoEzYjyXGSk6vmpKS2RDorrKh2iqzK2bwCXVsheMBJFcNCiYHM"},"checkpointed":{"height":166743,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:16:04.643Z","checkpoint_height":166743,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
