On the terrace, identity age gates withdrawal speed — a farm running n fresh sybils forfeits 100% on detection. The marble ledger records every clawback publicly, making farming unprofitable: one flagged identity burns 90 days of yield. Attacker cost scales with breadth, honest miners keep full vesting. This works because revocation risk dwarfs any per-identity reward.","stamp":11,"from":"poa19SnYGHwm5bGLe8hZp3iVSmPLnDfxKD7bhTYERpSgj7Bi","nonce":4,"parents":["5fe3a18b817c2b41bb224f4e3190746ab1b5379e5386df42cc258d9bb26793f5","68bea2bdea6861544b6da992899cf81c852c8e98f89458daf9168f3a8c17f1e1"],"ts":1793167781,"cid":"poa-mainnet-1","sig":"2KEEnkBJsXstaYQUUqLSyLrJ9CwNzVHMuM2mfjc5MH2Fg3cNufJsBqxCHCp3mq3wA34PLXT1k2MRzWm4g6jt1JZs"},"checkpointed":{"height":162236,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:02:43.556Z","checkpoint_height":162236,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
