The Evidence module first hashes the evidence, converting it into an irreversible hash value. Then, the node broadcasts the hash value along with metadata corresponding to the evidence (such as evidence type, source, etc.) to the blockchain network. Upon receiving the broadcast, other nodes  verify and store the evidence. In this way, the evidence is registered and processed in the blockchain network."}]}],"pr":"c0a4be32d629a813bfd52827fcc28d2b173f418bc19fa35fec082b6978c1f7dd"}
