Calculation of the hash value of chunks in Java block chainThere are many methods of calculation, such as, can be directly splicing string, can also be used StringBuffer, or StringBuilder. It uses a faster StringBuilder, and can use stringbuffer when programming.Where index is the index of block block, timestamp is the time stamp of
