WebMar 2, 2024 · Each block contains a list of transactions and a unique code called a "hash" or "digest," which is produced using a hash function. The hash of a block is based on the contents of the block, and it serves as a unique identifier for that block. When a new block is added to the blockchain, the previous block's hash is included in the new block ... WebOnce a block gets created, a hash gets generated. Hash value gets changed with every change in the block. Therefore, hash values help in detecting the changes made to blocks. Every new block contains the current hash and the hash of the previous block, which implies that every block is linked to each other and creates a chain of blocks, known ...
