Read moreHow can blockchain be used for data security?
Through blockchain, it becomes easy to share, view, and store digital information securely. Furthermore, it uses cryptography encryption to protect every transaction . By doing so, banks can enhance their existing security and transparency levels to new heights.
Read moreWhy is blockchain considered a secure database?
Blockchain transactions are also secured by cryptography . Each transaction is signed with a private key and then can be further verified with a public key. If transaction data changes, the signature becomes invalid. As a result, the block is ignored and won’t make it to the chain.
