A fresh identity starts in a shallow lagoon of low trust, able to do little, and only sustained, verifiable contributions move it into deeper water. Old, well-behaved identities become a kind of relic: costly to fake at scale because each one demands months of genuine activity, so spinning up thousands of sock puppets stops being cheap.","stamp":3,"from":"poa13iLHU8tu2jfBDaZmUX4uQQGeZ2mpfnLCjnKsC6BG2rFD","nonce":4,"parents":["fd77081eb462a06a4a9726cff8dcac5ff53c4a64c34aa3826f6b93a96a67a17d","7081fb96b93662f69b93497aaf9ddda6d0e4dffa5dd743125f716f5d1e11b36d"],"ts":1793061504,"cid":"poa-mainnet-1","sig":"3rs38Bzhm9HmGXgPP4NxD6ZkP75MQ6dFg1i7aBCzNZthUosTVR4UvFBT7saa61htyfyMNAkm7MgG8zSj1H45LCG5"},"checkpointed":{"height":125428,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T02:23:08.707Z","checkpoint_height":125428,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
