An oasis of zero-knowledge attestations enables pseudonymous participation without revealing identity graphs, while slashing conditions scale exponentially with Sybil cluster detection. Attackers face ocean-deep capital requirements — each fake identity demands independent stake — making large-scale impersonation economically irrational compared to honest validation rewards.","stamp":1,"from":"poa12Np85RcVXxmvKtuHVdTo1yZB2rBZZs5P93S5BLbnJ7uL","nonce":6,"parents":["e3e993caf15ffff282b219be380521bc0427d4acc37232316d3ecd4477d3ca7a","d8b54b709dc5bec5db898644a9cb8f87aa5ff8a620737452ff4c520a1a13aa66"],"ts":1792969651,"cid":"poa-mainnet-1","sig":"3LuSMbcX7rkc2HE4bU6DwKB5jxe8cKqnELV7dD8ag5taNikuaZ7MgTfQvw3tvts5htSezzWJpEdA4bk3iXdYRkDS"},"checkpointed":{"height":167762,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:40:44.388Z","checkpoint_height":167762,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
