Each block contains a certain number of data records, and the blocks are connected to each other through hash pointers. This chain-based structure forms an uncrackable chain of data throughout the system, as any tampering requires changing the hash values of subsequent blocks."}]}],"pr":"42ed2d1a2ca7d9089180031436140990dab8d709ccaffc09df84d8e2bb1d02ed"}
