The biggest obstacle to electronic migrations of many systems is the need to protect the details and to check the identity of users. Currently, the use of dual-factor authentication is based occasionally on a password. The problem with these approaches is that passwords are extremely insecure and authentication by two factors usually involves the sending of code via SMS or a third-party provider. The blockchain might be a solution to this problem. A 50 billion dollar currency is managed by blockchain. But authentication could be subject to the same cryptographic principles. Thus, blockchain authentication eliminates someone from maliciously modifying the ledger when they distribute a ledger to all network members. A majority of the network shall check its validity any time a block of data is attached to a chain. That guarantees the completeness of the ledger. You can then make sure to send passwords safely using public-key encryption, such as highly protected RSA encryption. The receiver could then search for an entry in the unchanged blockchain, which would result in a remarkably safe and reliable way of handling identity verification. These rules apply for the transformation into a stable, fast, reliable, and readily available service from the election process, state identifiers to dual-factor authentication.
