Blockchain is the exciting new technology that underlies the cryptocurrencies such as Bitcoin, Ethereum, Ripple, etc. It's an exciting time to be a blockchain developer as this is a young and happening field. My focus will be transitioning from a standard blockchain to a quantum blockchain that also uses AI technology as a software product. A number of startups have popped up in this sector. And (an example) Back Step Blockchain, Singapore seems one of the best players in the market.
