This new hash value serves as the identifier for the current block and also as  the hash pointer for the next block. This way, each block is interconnected with the next through the hash pointer, forming an immutable chain of data structures. In this process, the hash function plays a crucial role in ensuring the integrity and security of the blockchain data. In blockchain systems such as Bitcoin, the commonly used hash algorithm is SHA-256."}]}],"pr":"62942593c9798a37168822231063626257d2a3108774684362d6cde4b96f6ffa"}
