How does blockchain really work? I built an app to show you.
Sean Han

Just downloaded Node.js and blockchain-cli to my Ubuntu-Mate 64bit desktop. So far, so good.

09/06: “sudo apt-get install npm” completed without errors. Then coding a really simple hello.js, and running “node hello.js” confirmed that node.js was installed correctly. After that, I could “sudo npm install blockchain-cli -g” . But when I ran “blockchain”, that aborted with the following error:

class Blockchain {

By clapping more or less, you can signal to us which stories really stand out.
