Blockchain Authentication refers to systems that verify users to the resources found on the underlying technology of Bitcoin and other digital currency.
The blockchain uses public-key cryptography (PKC) to encrypt wallets, or the places on the blockchain where value or work is securely stored. Blockchain authentication therefore raises interesting similarities between the technology itself and securing it. With crytocurrency wallets being a main feature, identity and access management (IAM) for the blockchain is almost a given, however its user experience (UX) and user interface (UI) are very poor without a modern authentication component such as True Passwordless Security.®
It should be noted that cryptography engineers and blockchain developers often share an affinity for the two fields, making blockchain developers an important part of the security and innovation landscape.
Example:
"In the early days of Bitcoin adoption and blockchain use cases, the ecosystem was crying out for a modernization of the technology so less-technical people would begin working with it. Password-protected wallet apps were one answer to this call. Now, the digital currency wallets and blockchain apps are ripe for a true passwordless interface that welcomes more users into the next phase of these technologies' development and real-world use cases."
