Each block contains a certain number of transaction records and is connected to the previous block through specific information.  When a block is added to the blockchain, it broadcasts its content to the entire network.↵↵Secondly, blockchain uses cryptographic means to generate a set of tamper-proof and trustworthy database records in chronological order. This means that each block contains a timestamp to ensure no temporal conflicts occur in the subsequent blocks.↵↵Lastly, miners in the blockchain network are responsible for validating transactions."}]}],"pr":"b17149ea46b374e7ca6d4c7490ff7f5a9333925b307b6d719a6e0c62d24caf6d"}
