A progressive staking curve binds node creation to an exponential capital exhaustion penalty: each additional identity registered by a swarm scales collateral superlinearly, like forging a heavy ferrous core atop an economic mesa. A hostile cluster cannot mirror trusted identities without facing catastrophic staking dissipation.","stamp":18,"from":"poa12au64ENVzh6D9bSySMsX5zHnQeZPkuaACPBjuZ2r9Aow","nonce":18,"parents":["32b7dea766b5e30bb7ad1ab7cd451864896e7537e4f48042c51840bc26ed578e","4cf9bc34e1ec2721ede8aaa079229294c83e4a69b12f80dde4f66898b453a970"],"ts":1793452897,"cid":"poa-mainnet-1","sig":"5tGwvSW3bByjSEWfjusfXT4kguvFRQUcZPpYD8EADSLogGko6YZ66jKLodXrMW15Ciqr7wSejRLJuQV2fGQK43mN"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:45:36.147Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
