The three defining characteristics of blockchain technology that contribute to its immutability are decentralization, cryptography, and consensus. In a blockchain network, each time there is a transaction involving digital assets, its specifics are recorded to a block that consists of data, hash, and hash of the previous block. Depending on the blockchain type, different types of data are present in a block. The data for a bitcoin transaction would be the transaction’s specifics, like the sender, receiver, and coin count. A hash is a distinctive piece of encrypted data that is used to identify a block and its contents. To generate a new hash for the following block in the chain, this hash is processed along with the new transactions.
