Staking requirements scale superlinearly: while a single node enters a localized inlet of low fees, spawning a swarm triggers exponential capital exhaustion. An adversary attempting to flood the ocean of nodes faces onyx vault lockups whose compounding stake costs render mass identity replication economically unviable.","stamp":10,"from":"poa1DLavNHUWzs3C3AGe5ea817JWN5ELoJgb8W7iCSxZdz94","nonce":25,"parents":["27460af0e34cf1071b8c17883757a64b2d1d9ba41cbc0784acb338d61593e50e","b61c0c73fce79c4774c2888dcaae791759f5e483700058ad35a68b565b5aadb6"],"ts":1793603532,"cid":"poa-mainnet-1","sig":"4SkimEqvSTLcxdfdvwrMuSD24vrVFM3KnPSvYU9wnaVo2btAbwt99HuFgYgKRXco6n3KkRhkgGm3M39d9xC9Z2Wv"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:07:05.899Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
