Each entity stakes collateral tied to distinct node clusters, like cedar hardware modules or saffron cryptographic tokens. Joining an operational meadow imposes exponential capital exhaustion on minting identities, forcing attacker cost to scale superlinearly to bankrupt swarms.","stamp":1,"from":"poa1B25nosu1JAE4P4kDpfsgB3t6r7TZknEKomrXvmX4ZWjv","nonce":4,"parents":["e9bb234f9338f3f47f72a390a3da6bd1d8f1a88cdd4f85ec565a58650ad9fec6","f104799d4eec0f16c2907f2f3301340d931456291cab617dc7b3866b329984af"],"ts":1792924292,"cid":"poa-mainnet-1","sig":"5Buja8KG51fuyyyZPzDMnAGudp7anHvsJyys7ho3QdWsqRWmX45bcLD9Bsh1cJ9X8QXBXfG4fJ3GpftrrkwJJqxW"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:33:43.760Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
