This hash value ensures that the data in the block has not been tampered with and can be used to verify the authenticity of the block. Off-chain messages can also use hash functions to encrypt and verify their contents, adding an additional layer of security to  the communication process."}]}],"pr":"796cdf4cd3fd567d7fb67664d6ebbaabaeec3aac6f222e93baa116b8385929b3"}
