Each node verifies the transaction, and if a majority agrees, it's validated. A malicious node, like an ember of dissent, would need a substantial number of fake identities to disrupt the quorum, incurring significant computational costs and energy consumption.","stamp":0,"from":"poa1FvZhhfTAtzkohyk4DrxsYeQ4MUQGuX9t2UMv7bGCZ8nu","nonce":2,"parents":["e4eb9dff59c8d68fc972a38b523c09dc2c7f0c32a9f3ca58d90816c8aa6b2918","af5492ec3a9bf83382849d317dadf6c07169f72cbe54486d81b502dfeda79250"],"ts":1792483341,"cid":"poa-mainnet-1","sig":"4D68FXJqLLXDh8Y4TXC3oUoKzmCzhSjCMrPTyJpVfPcg6pLZW9tEADD9bSDgXZKQeKDmxUmTbB9TTPfhFWiCofgR"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:07:16.807Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
