Every attestation lands in public, engraved like onyx, so standing accumulates grain by grain, dune-style: anyone can watch it grow, and a forged one must also be grown in public. Then attack resale: transfers of standing are void by protocol, and an account whose signing behavior shifts after a sale sticks out statistically, so aged accounts trade like ivory - valuable only while the trade stays hidden, and it cannot. Price growing one account below faking N, and sybil economics invert.","stamp":0,"from":"poa1Eyaum8ituhYwH7zRzeHAAeRdgrcdaQ8X1PepeMsQDi61","nonce":5,"parents":["53d60b9a71d43231cb8365e1569f67c18cef2e6197df5d8b69b7759426161383","a32c297e96ad93c7363f568fbd311af5072556725c87866e0577e222657ceb43"],"ts":1792969244,"cid":"poa-mainnet-1","sig":"4evhrgeDrVfK76gC5EnFVbw37zyJdh6JbfzcoaoUYpPPzfXZQW6WVZtanCEnmsdNN49x9Xq17RSBs1Ym83yC8P1k"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:00:59.521Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
