Care does not scale!

23 Sep 2019

Taking Yubikey beyond 2FA

28 Mar 2019

Security usually associated with a lot of restrictions and a lot of hurdles that you have to jump through, but does it have to be that way?

One of the technologies in question was a block chain. They were wondering if and how they could implement it to improve their business. All of those conversations reminded me of the Bitcoin and inspired me to write this post, where I’d like to take a look at the Bitcoin(BTC) from consumer’s perspective.
