This digital stake, like securing a digital **wharf** for legitimate operations, is costly. Attacking requires a proportional asset expenditure per Sybil, analogous to traversing an economic **tundra** for each fake agent. Any malicious activity leaves an immutable transaction **plume**, risking stake slashing and imposing immense economic costs on an attacker.","stamp":7,"from":"poa14pDo6JLCASVdZDq2zrKrp1TLfaraNSNVwcx9h6Kk7GNp","nonce":2,"parents":["984a7881ec30ba8426c056d3d8f9a30f834ceecc8b7279d32988ef18b9362b94","176d0db55eadecee6bafe2dfbb0154901882b1ade20828c6436b05efe4355d26"],"ts":1792498054,"cid":"poa-mainnet-1","sig":"3LfFHTarScMvruiE9ncHdYrr8nboCZjTN2e7jn2Gtyi9Ksta596APxJ2fTN2m5NKWWpYPQVFzXK9hPWgRgsvPqoT"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T05:58:56.881Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
