Blockchain In Smart Cities

We are media partners to the coming Smart Cities Expo in Barcelona, look forward to report on site to you next week. Here is background to blockchain adoption in smart cities:

Blockchain is not only a platform on which large amounts of data generated by smart cities may be stored 1) safely;  2) without the possibility of unauthorized changes; and 3) with the possibility of flexible selective access without mergers and associations.

The most important thing in the application of blockchain for smart cities is that blockchain can serve as an “interoperable platform”, which gives residents of smart cities the opportunity to influence decisions made with respect to “hyper-communities” and local communities – by the widest  a range of issues, from budgeting to voting.

Blockchain is also a kind of reputation management tool, since the population of smart cities requires higher standards of services and environmental care from utilities and the urban business community.

Universal IDs

A single, easily verifiable method of proving that “I am exactly the person who I am according to my words / actions” will save a lot of time and effort for a resident of a smart city.  At the moment, many different methods are used, although there is a tendency to create a single method (example, Denmark: Nem ID).

This feature is ensured by the openness of  blockchain to various standards of data storage and processing.

The inability to make changes to existing blocks and a flexible system of access to individual block elements – these structural properties of the blockchain are the basis for ensuring security against hacking and ID theft.

Prioritizing Local Producers

The provision of both critical and providing an improved quality of life services to companies and organizations that are located near the place of service provision is a key concept of a smart city. 

This ensures the uniqueness of urban areas and the branding of local identities.  Blockchain platforms, including direct marketplaces, enable providers and consumers of such services to communicate directly, submit and quickly resolve complaints, evaluate services, including ratings, and even manage services through DAO.

Land and Property Fund Management

Blockchain cadastres and registers make it possible to minimize, and actually cancel, certificates and extracts of ownership, since the inclusion of a block confirmed by the consensus mechanism in the blockchain is proof of ownership.

In many cities, this has already been implemented by traditional methods, but the use of the blockchain allows the joint use of various cadastres, for example, land, buildings and infrastructure without the need for their merger and organizational unification.

Smart Energy and Water Management

Renewable energy, conservative use of water, minimization of harmful effects on the environment are policy priorities of any smart city. 

Data for all these areas can be stored in a compatible, regularly updated, real-time blockchain register, on which it will be possible to track any actions and responsibilities of each participant in the process, including joint and several liability, up to the source.

Blockchain can be implemented both at the community level and at the individual level so that end consumers can realize the volume of their own use of resources and adjust consumer patterns.

Urban Transport

Blockchain has been repeatedly proposed for use as a single payment point for various types of public transport.  In such a system, in addition to buses, trains and the metro, you can include payment for car sharing (carsharing) and city taxi services.

Communication Smart Devices

Blockchain is a single platform on which the end-user company, the organization can create its own safe and mutually compatible control system for the combination of smart devices surrounding them.

Security for the Internet of Things

The more data we collect, the more difficult it is to ensure the security of sensitive information.

The principle of 51% consensus is to protect blockchain platforms from hacking.

Taking into account the large amounts of data used by IoT systems of smart cities, blockchain is the main technology of data security systems in smart cities.

Urban Planning

Blockchain technologies can reduce administrative costs associated with urban planning to such a large extent that blockchain is becoming critical to the existence of smart cities.

The ultimate goal of applying blockchain technologies in urban planning is to ensure public participation in resolving urban and regional issues through secure and affordable voting systems.

Mutual Transparency of Subdivisions of City Administrations

Using the blockchain platform as a single source of information will reduce double costs, minimize overlapping efforts, and optimize the coordination of plans of various city departments.

Similar systems are already in use in Dubai and Singapore.

Blockchain is also successfully used in tenders for public procurement.

Universal Storage Platforms

The blockchain provides the ability to merge data used in smart cities – smart meter readings, smart network metrics, vehicle traffic data – without the need for a combination of information platforms and the reorganization of urban services.

In fact, blockchain is the only suitable option in order to organize a universal platform for storing the data necessary to ensure a high quality of life in smart cities.
