Think about Blockchain-based multi-factor authentication system . You can use two different Blockchain platforms in conjunction with each other in future user login system. One Blockchain platforms will create the authentication codes that will be used by a user to gain access to a website or program after they enter their standard username and password.

And the other Blockchain platform will be responsible for receiving the codes to confirm a user’s identity when they try to conduct a transaction through the platform. The possible transactions that can be conducted include data transfer, contract generation, and asset transfer.

Remember though blockchain’s ledger is public, its data communications are sent and verified using advanced cryptographic techniques, ensuring that data is coming from correct sources and that nothing is intercepted in the interim. Thus, if blockchain is more widely adopted, the probability of hacking could go down, as the cyber protections of the technology are more robust than legacy systems.

One way blockchain reduces conventional cybersecurity risk is by simply removing the need for human intermediaries — thus lessening the threat of hacking, corruption, or human error.

Other potential applications include using blockchain to provide massive scale data authentication: for example, using blockchain-enabled Keyless Signature Infrastructure you can easily verify data transactions for cryptographic assurance of their integrity and authenticity.

And this is just a public part of Blockchain, although many enterprises are moving towards Private Blockchain network, where you have the real meat.
