Blockchain has been one of the hottest buzzwords of the last few years. Initial Coin Offerings, tokenomics, the crypto-bubble, dApps, Bitcoin and Ethereum, all these words have dominated a large part of our professional lives, for those of us who are involved in this space.

Blockchain is a powerful tool, but it is often misused. One of the most common issues with blockchain is that it is used to solve problems that could be solved through traditional relational databases. Other issues relate to using wrong tokenomics models, choosing the wrong type of blockchain or not being aware of problems like scalability and speed of transactions.
