Event description


Blockchain - how to do it right

During the workshop we go through the basic pitfalls of blockchain. At first we go through the basics to cover the foundation. To warm up we set up the blockchain and development tools related to it. We show what smart contacts and tokens are.

We will strongly focus on dangers and difficulties when using blockchain, and why it should always be supported by classical database. We will implement basic application which stores transaction data in blockchain, supported by a typical database, to handle data which needs to stay mutable.
