The blockchain is a subject that fascinates and which intervenes in the majority of sectors of the economy. Although initially applied in Bitcoins and cryptocurrencies, its applications are increasingly varied. Here is an overview of its use for Smart Cities.
Towards the “Blockchain Of Things” (BoT)
The Blockchain of Things is a new concept that consists of linking the Blockchain and the IoT (Internet of Things). This concept consists of taking advantage of Smart Contracts in order to create an interconnection via the Internet of Things, allowing them to send and receive data.
VivaTech 2022: thinking about the future, one innovation at a time
The “Smart Contract” is a secure transaction carried out via the Blockchain network. This transaction is subject to conditions written on a computer program. The “Smart Contract” will consist of programming hypotheses in the form of code in order to be able to link the actions whose execution is triggered automatically when all the agreed conditions are met.
SmartKey, a young blockchain company, stands out today as a disruption in the era of IOT and is the only platform to connect blockchain and IOT with the aim of democratizing this new concept of “Blockchain of Things”. ”.
The SmartKey system, the future of IOT technology
Smart Key’s goal is to become the IOT communication standard by combining second-generation Oracle technologies, the Blockchain of Things and the power of decentralized finance (DéFi) to create a unique access key called Smart NFT.
More simply, the universal communication system of SmartKey would make it possible to standardize all the IOT applications used for each service.
These traditional services will therefore be able to reinvent themselves and greatly improve thanks to the use of this system.
How can the Smartkey system benefit the city of tomorrow?
Thanks to this democratization of access to services, we can imagine many use cases for Smart Cities. The SmartKey system enables car sharing and provides automated access to cars, homes and hotels. In addition, the DeFi allows users to pay for these services in cryptocurrencies.
Many scenarios are then possible: automatically unlocking rental cars, accessing accommodation or hotel rooms, allowing emergency services to access secure areas, etc.
The Orange and SmartKey partnership, a very specific use case
In July 2021, Orange is teaming up with SmartKey to offer the first Blockchain Internet of Things SIM card. This SIM card uses Blockchain technology to enable more secure, smooth and fast sensor management.
Through the use of this SIM card, the emergency services will be able to access secure areas more quickly. This new SIM card was tested in the city of Olsztyn in Poland and its uses proved to be very promising. Following these tests, Orange distributed more than 2 million SIM cards across 80 Polish cities.
The capabilities of the SmartKey system and more generally of the Blockchain are not yet used in Smart Cities. Nevertheless, their automation of access to services leads us to believe that this technology would have many advantages in the ecosystem of Smart Cities.
