Will Blockchain Be the Secret Sauce for Smart Cities?
Blockchain, the underlying technology for cryptocurrencies such as Bitcoin, has also emerged as a secure ledger platform that will rapidly accelerate the adoption of smart city digital services. In the areas of energy and mobility, for instance, blockchain has enabled transactions of everything from solar energy credits to paying drivers and cutting costs for participants in ride-sharing programs by leveraging existing systems - effectively cutting out brokers or third parties.
Ford, Silicon Valley stealth startup Autonomic, Qualcomm, and Waze announced last month the development of a cloud-based mobility platform for cities to manage self-driving vehicle ride hailing, deliveries, and bicycle sharing that will feature everything from payment processing to parking and traffic logistics. The Ford GoBike share program, which launched in five Bay Area cities in 2016, was said by knowing observers to be part of Ford’s strategy to build a repository of data and usage habits from younger urban shared-mobility users. GoBike was also a means to increase its public-private partner non-auto cred in regional transit planning through work with the San Francisco Bay Area-wide government agency Metropolitan Transportation Commission.
In terms of its new urban cloud ecosystem, Ford appears to be trying to avoid the “walled garden” approach of Tesla. For now, Ford is inviting other automakers to join the cellular vehicle to everything (CV2X) platform, which is planned to be operational by late 2019. Reading between the lines (none of Ford’s many announcements coming from the Consumer Electronics Show specified blockchain), it is evident that these systems will be leveraging blockchain, as Ford began quietly hiring blockchain engineers in mid-2017 and continues to do so into 2018. In New York City, the 115-year old automotive company has a City Solutions group working with Microsoft, Google and others on urban business challenges from “drones to blockchain”.
Other car companies such as Toyota since early 2017 have already been working with MIT’s Media Lab on their own blockchain-based self-driving vehicle paradigm. The goal is to ensure that software can help advance autonomous technologies through monitoring and distributing vehicle safety information, road mileage and other use data, and through the reduction of fraud.
Looking further under the hood, we begin to discover how blockchain will become the lingua franca in urban metros. Consider how the Tel-Aviv based ride-sharing company LaZooz is building a decentralized, ride-hailing system that uses blockchain to pay system drivers and to avoid the estimated 10-20 percent or transactional revenue that goes to an Uber, Lyft, or AirBnb for their services. LaZooz envisions others from public, private and non-governmental sectors building apps on top of its technology.
In energy, blockchain is also likely to have significant impact through facilitating transactions that bypass gatekeepers such as publicly owned or municipal utilities. In Brooklyn, the start-up LO3 worked with Siemens to demonstrate how blockchain can be used as a means to facilitate localized peer-to-peer transactions for PV solar energy credits through an urban microgrid. The Brooklyn Microgrid has a rapidly expanding base of 100 local residents using blockchain to share credits for excess solar energy that is generated from well-situated local rooftop arrays. In this case, the credits are reinvested in renewable energy and energy storage systems, but at the heart of blockchain value proposition is that such transactions are secure, verifiable, and can be used for financial credit in other transactions - instead of having to sell excess energy from solar back to the utility grid under utility purchasing constraints.
Noel Shannon from Hyperion Solar energy described in Power Technology how blockchain in energy markets can effectively create an open-source funding opportunity for renewables from solar projects, with each blockchain cryptocurrency unit representing a unit of solar energy, say one watt. “It takes a lot of time to get funding, to get banks, debt, and equity, as there are a lot of negotiations that take forever.” Shannon said. “Blockchain, and an ICO (Initial Coin Offering), offers a way of resolving that, by effectively crowd funding.”
Forbes recently provided an extensive scenario where, outside of retail purchases, blockchain would be at the juncture of nearly every urban transaction. The scenario showed how each interaction would be transparent, verifiable, and nearly impossible to forge or hack, while adding to the valuable stores of Big Data on which artificial intelligence can be used by cities and their partners to analyze for future improvements and efficiencies. In effect, blockchain frees interrelated transactional records from being isolated from one another and needing verification, similar to how the internet freed communications and information from bureaucratic silos.
The fully realized smart city is rapidly taking shape. Bloomberg New Energy Finance reported an increase in major public-private smart city technology deals to 35 global cities in 2017, up from eight in 2016. Blockchain will further accelerate that progression. Smart cities started in the early 2000’s with broadband and progressed to solution architectures such as LED lighting systems, where now digital services using predictive analytics built on the Internet of Things generating Big Data are becoming prevalent.
Now we are entering an era where, thanks to blockchain, there will be a way to keep a running tally on transactions to provide frictionless financial settlements, claim processes, energy generation, and so much more.

Spotlighting innovations in urban sustainability and connected technology
Right-sized living is far from a new idea. The architect Le Corbusier was a pioneer, from his cabanon at the Cote d’Azur to the super-efficient and well-designed density of Unite d’Habitation. This was a good idea then, as it is now. This is a classic case of the importance of the underlying rules of the game – the land use regulations, zoning, and building codes that guide our built environment. These more technical matters aren’t nearly as sexy as the shelter porn in Dwell magazine. But you can’t have one without the other.
California recently became the second state to pass a 100% clean energy standard, three years after Hawaii passed a similar law. As the fifth largest economy in the world, California has a tall order to fill in terms of making the transition to clean energy. How can California, and other states that wish to follow suit, fulfill this ambitious task? They will need to provide affordable, relevant, and accessible energy options to every one of its residents, prioritizing those who have historically been overlooked and left out of the clean energy conversation due to economic circumstance or social inequity.
Planners, engineers, and public health professionals all speak different languages. They may even use different terms to express similar ideas: for example, a planner may recommend tactical urbanism to improve neighborhood walkability, whereas an engineer may ascribe experimental countermeasure terminology to the same scenario, and a public health professional may view the solution in terms of an intervention. And community members may find all these terms unintelligible. In our focus groups, we heard that practitioners need to “get people on the same page” because of the differences we carry in our heads about transportation concepts.
