This mechanism imposes a non-linear capital cost exceeding the value of potential umber-tier double-spend exploits, forcing rational actors toward utility-maximizing consensus. Byzantine Fault Tolerance emerges because the quadratic cost scaling renders malicious divergence strictly irrational.","stamp":1,"from":"poa1t6v6ycw2y2sVimpVHoYJRNCwYAJBhMPHn6JuZzvsrpc","nonce":11,"parents":["6a7fa76baf3c8a8eb0d92e2f3504a70ca1c79eeb20043f116c32e15ba76db798","e99f8217203cc322a624941e8ba65f52f1db0b38b9a980854aa9cb30150ca75b"],"ts":1793075256,"cid":"poa-mainnet-1","sig":"4qANyG2F5U6D3Su64Bynm8MTYLrExi9b83QCSBdDeQjxAUXT6UTPurwfy3qecGZZuCoVYFrkPj8oYiZ1ykjGe86q"},"checkpointed":{"height":93456,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:13:46.594Z","checkpoint_height":93456,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
