I wrote a book about blockchain programming: https://www.packtpub.com/big-data-and-business-intelligence/...

I didn't get rich by writing this book, but it's very useful for networking in blockchain community. It's like an expensive name card. It also boasts my reputation.

I developed a blockchain framework called Mamba: https://mamba.black

For those who are familiar with blockchain programming, Mamba is like Truffle but instead of based on Solidity+JavaScript, it is based on Vyper+Python.

For those who are unfamiliar, Mamba is like Ruby on Rails but it's for writing decentralized / programmable money applications.

My plan for 2020 is to write more tutorial articles in Mamba website and develop more features in Mamba framework.

For business: I am helping a company build their programming bootcamp (not related with blockchain).
