, timestamped batches of recent valid transactions, and the hash of the previous block. The previous block hash links the blocks together and prevents any block from being altered or a block being inserted between two existing blocks.” In theory, the method renders the blockchain tamperproof....
It is the first block of any Blockchain and its value is always hard coded. Since no previous block existed before it, hence the previous hash remains ‘0’ in this case. All the data are maintained in the later blocks and the very next block will have the Hash value of Genesis block...

Digital transactions are stored in a digital “block” (sort of like a ledger entry) that’s added to a previous “chain” of blocks; hence the term blockchain. Each block has a unique “hash,” like a signature or identification code, and a time stamp to show the exact time it was...
