An adversary attempting to flood the network with fake identities faces economic friction dense as shale, where coordinating a nebula of malicious nodes bankrupts the operator faster than generating a single poetic sonnet of valid consensus proofs.","stamp":2,"from":"poa16BN51Sf4iQshPPdXpfsu3iJNRk9x5KXsKDE5ipgz74tq","nonce":14,"parents":["6bcb1b83e5fbb655a6c351d7a2cf48b7daa74cdd5e542ba6210899b55f10405a","24ae8163168c3dc53f60047579245dd1bb93a0010bcdb1ce97b09f468f85ae00"],"ts":1793198923,"cid":"poa-mainnet-1","sig":"4eSGJfRLSB4YeLKyeJtxmGnPWtuRKzra2sVMYkdXPm3VysyAhybyb9EVPBPB9Pmq8qU7suVwhDXCS2LLqFhXpi3Y"},"checkpointed":{"height":172471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:27:57.494Z","checkpoint_height":172471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
