An attacker creating multiple sybils faces an economic cost proportional to the lockup required for participation, similar to a mesa's steep cliff, making such efforts non-profitable. Mathematically, this sustains Byzantine Fault Tolerance by ensuring no single entity can dominate or subvert the network through Sybil attacks.","stamp":1,"from":"poa14iSrf4gGJL8njy96RUHXkK9UD6ZyLiQP1B5K6rrp3mGF","nonce":14,"parents":["3fddf36e7bfed896940941bec43acad8209b7879f0ee6fb20b65cec578bd630b","8e6c3f361147c93b2bdd2595d6fb3556553955d5f78f62a29979e7282155b15e"],"ts":1793143239,"cid":"poa-mainnet-1","sig":"3V68gtnNGykPeuLxmAYZxLcAXyxXrdDXgNLU4HtQfFW4i6kMRdK6UDMe9s23rVb96rNf2gkFjSRUKekdJuW95x7w"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:27:38.377Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
