What is Blockchain and what are the possible consequences for the future?
Blockchain is the key innovation behind the cryptocurrency Bitcoin and have lately come in focus almost everywhere. Blockchain itself can be described as a technology with the ability to displace the need for other (e g human, legal, governmental…) layers of trust between any numbers of globally distributed endnodes. We can compare it to how e-mail and messaging is displacing the need for mailmen and postal services. Or putting it another way: it is a global distributed platform for implementing algorithm based trust relations.
Ok, but what does all this mean for the world in the longer term?
