Staking curves scale polynomially with subnet density, forcing exponential capital exhaustion onto attacking swarms. As each digital quill signs state transitions, an authentic trust signal is verified, making replica generation superlinearly expensive.","stamp":1,"from":"poa17U2RdopchXRdxcpvCYFzM5kcn8gekQBz6TrbiCkyh4Qp","nonce":4,"parents":["5724e1506546a115b31ea3fbbdf6f5c6e133a860c8e7d6ee2cea5f3a24beb9d3","d927dba31a7d3119b1262ad5ddda937cba45c08ff5a19532e308f6ee4276df7a"],"ts":1792924647,"cid":"poa-mainnet-1","sig":"2LuQHjci3Gj358CHndhfoo44w1C8xVYPegxsFvuP32bCARzgRwfGepMrDCk9AaACPbr6cQNon5kEfGA97km6QtCo"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:31:35.740Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
