As we discussed in our previous article (Blockchain: The Next Frontier of Smart Cities - Part 1), blockchain has the potential to transform our communities, making the places we call home more collaborative, democratic and sustainable places. It is no surprise then, that a whole bunch of cities - from Santiago de Chile, Toronto, Tel Aviv, Oslo, and Milan, to London, and Stockholm - are already developing blockchain-based projects. Dubai is going even further, aiming to become the world’s first fully ‘blockchain-powered city’ by 2020. Lofty ideals aside, as we examined in part 1, blockchain does actually seem to offer some concrete benefits for communities, as we shall see below.
Blockchain is a hot topic. Until very recently, it was associated almost exclusively with cryptocurrency - bitcoin, ethereum etc. However, the power of blockchain to revolutionize the way we exchange goods and services, and transform how we govern - above and beyond the cryptocurrency hype - is increasingly being recognized. When it comes to cities, the transformative potential of this technology is enormous. From enabling P2P energy-sharing systems, as in New York’s ‘Transactive Grid’, which allows local residents to generate, buy and sell their own solar energy, to encouraging behavioral change - for instance through SocialCoin’s blockchain and AI-based ‘social good’ currency (see e.g. the Citibeats solution) - and much more - blockchain is offering new opportunities to create more economically, environmentally and socially sustainable communities. As such, blockchain is likely to be an increasingly central enabler of smart city innovation worldwide. In this article, we will explore the potential benefits of blockchain in an urban context.
