"Transaction data within a blockchain is kept secure in several different ways. Since each block within the chain is connected to other blocks within the blockchain, it is difficult for hackers to manipulate the data without impacting the adjacent blocks. Another feature is that the blockchain is widely distributed among many different nodes. Changing the transaction data in a single node will be detected by the other nodes. Additionally, blockchains use encryption to protect data that is transmitted between users. Taken together, the security measures ensure that blockchain transactions are secure and can be trusted."
