Well, the sandbox is not about the technical implementation, but the business. The CVM doesn't care if Tokenization is done with A or B. But, yes, I use Signum for two use cases. One is about true tokenization with dividend payouts as an alternative investment opportunity bound to real world assets, i.e. Real Estate and soon commodities. First is already operational, but we need to grow now. And this is where we started the process of acquiring a license from the CVM.

The second case is about tracking recycling of plastic and other materials. It's not tokenization in the classical sense, but built upon a combination of transactional data, smart contracts and (utility) tokens

I'm developing (first phase almost finished) a pilot system which is being applied and tested soon in a real world environment.

Of course all Signum only
