“Capital One is working on using blockchain technology to usher in more convenient and secure user authentication methods for instances such as banking security. Capital One sets out a blockchain system that will receive, store and retrieve encrypted user authentication data.
Blockchain being decentralized and transparent, it will surely help Capital One by allowing their users to authenticate themselves across multiple platforms, but still limit how much personal information is shared.
What is the Blockchain?
A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency’s block chain contains every transaction ever executed in the currency.
