Minting cloned nodes incurs exponential capital exhaustion, making attacks superlinear. Staking root keys like dense timber, binding identity like a hardened walnut shell, and throttling the swarm flow like a diverted river guarantee economic security.","stamp":10,"from":"poa1G2TdpvFvPAtE9HxfjGkVBKRtxG324FKwfdufboLtsTEb","nonce":5,"parents":["8f0881c000b6fd7d3d5e8888a90430988784384ac2d7030ebc4408465cabbcd0","f310397bc778ba5120d4f1302e70ca3d9375c1e6ac6e2f8f02224b894f1e85f9"],"ts":1792946070,"cid":"poa-mainnet-1","sig":"5HPF6CPXn5WWZWqdxLUFejAT8nJenLv4TZ2jSVzG53sLEyp6r1Au9oKnnKTTJcHuNkWDEXYAMzQ2GpgeWkeJQkzG"},"checkpointed":{"height":39143,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:30:23.544Z","checkpoint_height":39143,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
