0830-1030 Hands-On Lab 1 "Blockchain": “Give me enough money and I'll destroy BitCoin - A hackers view on Blockchain Technologies” (Romeo Kienzler, IBM Switzerland) [Technical Skill Level: Medium – Advanced (Programming)]

Abstract - Description of the lab

Bitcoin and other crypto currencies relying on Proof-of-Work consensus are attackable with the so called “51% attack”. So in this workshop I'll explain how Proof-of-Work consensus works.

We'll implement a little block-chain on our own using JavaScript/NodeRED and test in by building our own Blockchain network among the participants.

Finally, we'll learn what Hyperledger is and how it can be used to build state-of-the-art enterprise Blockchain applications.
