Welcome to the Consensus Based blog!

If you have already checked About, you know that my name is Johan Loo. I am a tax lawyer and a research associate at the Utrecht University (Special Interest Group Blockchain for Societies).

This blog covers news, backgrounds and technical analysis about blockchain and blockchain use cases. One of the use cases is cryptocurrency but not the same as blockchain! As you will discover, cryptocurrency is not the only blockchain use case (but it is the most well-known).

As a lawyer I find it very exciting how blockchain can change the law. Blockchain has also the potential to be disruptive. Many sectors will increasingly be affected by blockchain in the future.

My goal of this blog is to create more awareness and cover blockchain and blockchain use cases in an easy-to-understand and accessible way. 

I post new blogs on a very regular basis. If you have any comments, suggestions, new ideas or subjects you want me to discuss, I would love to hear them. I also appreciate your feedback to the blog. Use the form under Contact to get in touch.

I really appreciate you taking time out of your busy day to check out my blog! 


Blockchain and the floral industry

Blockchain technology has the potential to transform the floral industry by increasing transparency, reducing waste, and ensuring ethical practices. With blockchain, every step of the supply chain can be tracked, from the origin of the flowers to their delivery to the end customer. This allows for increased accountability and can help prevent fraud, such as mislabeling the country of origin or using pesticides that are banned in certain regions. Additionally, blockchain can reduce waste by optimizing transportation routes and preventing overproduction. This can lead to cost savings for both growers and consumers. Overall, blockchain technology has the potential to revolutionize the floral industry by creating a more sustainable and transparent supply chain.

Blockchain and Metaverse: interoperability

An interesting development is how blockchain can cooperate with the metaverse. The metaverse is still a bit surreal, and not many people believe the metaverse is going to have an impact. Which way this development will go is anyone's guess. Nevertheless, it will be interesting to see how metaverse and blockchain can work together.

Digital signature algorithm: the underlying code

The digital signature is the main component of blockchain technology. Without a digital signature, blockchain technology wouldn't be safe to use. In this blog, I will provide you with a sample code to implement in your own blockchain. Digital signature isn't only used for blockchain technology but can used in various applications where transactions is a use case.
