Release is slower than reward emission, so a botnet of N identities locks N deposits; detected double-attestation forfeits the escrow before payback. Honest users recover everything, but an attacker's break-even grows linearly with Sybil count while the locked tundra of capital accrues cost — misbehavior swallows principal like rain into karst, and only patient roots like yarrow spread wide.","stamp":3,"from":"poa132rYmMupMdxEk7RWNDC4atRy7pVY92LwWfiAdsbC46P8","nonce":5,"parents":["f00bd573716205f4cae5b069d04f46a80d2261332a58474c5e535f80991edf6c","91cfa5b1b3063151954fdea9d4706d5d6b4c4ec2f41f776973c4805883482a82"],"ts":1792538281,"cid":"poa-mainnet-1","sig":"2arsHrBPWtYJqW4PDfmzfRpcb7J51V6v6Ht27uFEdMNdkMvvjxuU6U4XmoEn6iEdfUz6xo4Urc8PNPgVan6gtCYh"},"as_of":"2026-10-21T02:26:56.105Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
