Cities that have a variety of stakeholders know that the exchange of data between stakeholders is essential for achieving highly convenient urban services. 

On a global scale, Smart Cities have embraced blockchain as a fundamental block to urban planning that enhances the way citizens of those cities live. Various incentives and projects have already made global headlines, with Dubai being a prime example of a city that has established itself as a global leader in the smart economy and the first blockchain-powered government. The public sector is by far not the only segment of a smart city that stands to benefit from the many applications of blockchain technology. The private sector is further exploring the possibilities and potential that can be applied to business processes to aid companies of various sizes in competing on a more even playing field, advancing their ability to be strategic partners to Smart City projects. 

How Blockchain is making cities smarter 

Blockchain has come a long way from only being recognized for its association with cryptocurrencies. Nowadays, blockchain technology can be applied to pretty much every sector and industry where a high level of security and trust is needed. Let’s take a closer look at some blockchain examples and ideas that are reshaping the landscape of urban management and development. 

Enhanced Cybersecurity 

It has been reported that Cybercrimes are on the rise as society moves towards a highly digitalized era where cities are growing more reliant on technologies for their daily operations. A recent publication by Embroker has suggested that cybercrimes will cost companies an estimated USD 10 trillion by 2025. Blockchain is thought to be extremely helpful in reducing the risk of cyberattacks occurring in multiple fields. A few examples of how blockchain can support and improve cybersecurity include areas such as IoT security where end-to-end encryption, secure communication, and authentication are made possible through the use of blockchain, aiding in improving cybersecurity with AI and IoT devices.  

When it comes to software downloads, the authenticity of potential updates can be verified using blockchain as a method of preventing malicious software from being installed. In the case of identity protection, blockchain validation techniques, like cryptography, can be applied in the restraint of identity thefts like driver’s license identity theft or mail identity theft, for example. 

Upgraded Healthcare 

Blockchain offers an extensive range of applications and possibilities when it comes to the healthcare sector and is already transforming the industry in various ways. Blockchain technology is being used to create a distributed system for patient health records, with transparent supply chains for medicines as well as managing the outbreak of harmful diseases. With the adoption of blockchain increasing, it will soon be possible for the entire process of diagnosing and treating patients to occur over blockchain, including secure financial transactions.  

Additionally, blockchain can be integrated with other advanced technologies such as AI to further enhance the healthcare sector. For example, when combining blockchain technology and AI, it will be possible to diagnose patients through the use of wearable diagnostic tools which will then allow for the diagnosis to be shared with a medical professional via a secure blockchain link. After that, patients and doctors can set forward a smart contract for further treatment. Similarly, those smart contracts can be applied to insurance claims, and in the case of telemedicine, patients can be treated without the need for an in-person visit to a doctor.

Better Management Of Waste 

Blockchain has shown great potential in enhancing the management capabilities of cities when it comes to maintaining a clean environment and high hygiene standards. When integrated into a city’s ecosystem, blockchain can provide real-time tracking of various aspects related to waste management. For example, it can offer transparent, immutable information regarding the amount of waste collected, who collected it, and just how the waste is being circulated through the network and recycled or disposed of. Additionally, governments could also incentivize waste management as a way to promote cleaner cities with the help of blockchain. This could motivate citizens to actively participate and contribute to better waste management.

A More Comprehensive Education System 

One of the most useful and impressive applications of blockchain for Smart Cities has to do with simplifying processes within education systems. Educational institutes have to deal with a tremendous amount of student data daily, which often means transferring this data between multiple institutes which can in turn be incredibly time-consuming and often hard to do. Blockchain has the potential to solve this problem by creating a centralized, immutable database where different academic institutions can easily access and share information across the blockchain network. This will help tremendously with various administrative tasks. Furthermore, establishing secure networks of this kind will also help reduce fraud instances, such as creating fake mark sheets, as student data will be impossible to alter due to the immutable nature of blockchain. 

An Increase In Energy Savings 

The entire world is heading toward a greener and cleaner future thanks to innovations in various sectors such as technology and intelligent urban development. Minimizing our use of resources has become critical as urbanization is on the rise and the world’s population continues to increase. Conservation of resources has been a primary focus in the development of future Smart Cities which includes blockchain technology. There are multiple ways through which blockchain can help increase energy savings in smart cities. For example, a blockchain-based network could be implemented to monitor citizens’ energy consumption. Citizens would also be able to trade surplus electricity with other members in exchange for incentives. 

Improved Efficiency In Mobility 

One of the major hurdles for cities, especially those of large sizes, often has to do with the effective management of a transportation network. The concept of smart mobility was created as a means of improving access to modernized transportation systems that are efficient for residents of cities and sustainable in terms of reducing the impact that the transportation sector has on the environment. Blockchain technology can be applied alongside IoT devices and systems for continuous real-time tracking of vehicles and passengers. Various applications of blockchain technology can allow transport decision-making authorities to optimize how they strategize their routes and schedules, adapting to the different needs of commuters and achieving better results regarding environmental and sustainability goals.

Furthermore, an efficient transportation network that successfully leverages blockchain technology can allow users to pay securely for transportation services throughout the transportation ecosystem, regardless of which mode of transport they are going to choose. Blockchain offers a more comprehensive and in-depth understanding of a commuter’s profile as its capabilities of retaining and storing vast amounts of data allow for the maintenance of the entire commuter’s travel history, behavioral patterns, preferences, etc. It also lets agencies monitor the performance of employees such as drivers and other valuable resources. Blockchain can also serve as an enhancer for Mobility as a Service solutions, where a variety of additional services can be provided to citizens in the form of car-sharing, payments, insurance, and maintenance. 

Blockchain has shown great potential in simplifying, enhancing, and securing various processes, and operations within a Smart City ecosystem, stretching to many sectors and businesses. Let’s briefly go over a few more examples:
