<human>:  How does blockchain help achieve data security in business?
<bot>: Blockchain is an innovative technology that can be used to help secure data in business by providing a secure digital ledger of transactions that are stored in a network of computers or nodes, making it virtually impossible to alter, delete, or tamper with data. It also provides strong encryption techniques, ensuring that data is only accessible to approved parties. Furthermore, the distributed ledger technology of blockchain helps ensure transparency in data and ensures consensus among different users or nodes to approve a transaction, thus providing an increased level of trust in the data.
