I admire your entrepreneurship, but the idea of decentralized smart cities using blockchain and crypto is not new. It gets talked about at blockchain conferences since years. Many crypto enthusiasts have a similar dream of what the ideal blockchain smart city would be (green, sustainable, decentralized etc) and I'm definitely among them.
But turning a dream into reality is the difficult part, and If you can be the first to make it reality would be a remarkable achievement. It will require huge funds but I also believe it is possible.
On a smaller scale and on a smaller budget Xaurum Gamma created a crypto smart street in Croatia for tourism.
Soon Liberland will be launching an ICO with even bigger ambitions as they want to build an entire Nation on the blockchain.
So we live in exciting times where nothing is impossible and where these new technologies will inevitably impact our lives . Will be keeping an eye out for your ICO too. Best of success on your endeavours.
