Decentralization and Immutability of Blockchain KYC

Decentralization means that there is no central authority controlling the blockchain. Instead, it is a distributed ledger which means that copies of the records are stored on many computers (nodes) across the network. It eliminates the need for a central authority to manage KYC data, reducing the risk of data breaches and unauthorized access.

Immutability means that data recorded on the blockchain cannot be changed. Each block is linked to the previous one and altering any block would require changing all subsequent blocks, which is practically impossible. This ensures that once an identity record is verified and stored on the blockchain, it cannot be altered or manipulated, providing a reliable source of truth for KYC processes.

Overall, decentralization and immutability are key features of blockchain that enhance the security, transparency and efficiency of KYC processes, making them more reliable and trustworthy. In the context of KYC, decentralization and immutability offer several advantages.
