For a smart city, there's only one solution: Blockchain

This series of 5 articles has been designed to give you a better understanding of our solution and our knowledge. The solution to :

-Smart grid, and economic recovery

-interconnection, which is a priority for smart grids

-lack of regulatoryegulatory toolsires

-Data security which is foundation of the system

-Disintermediation, a key factor key factor for profitability

could be summarized to the use of a single technology, the contours of which can be understood thanks to the elements we will outline in this article.. Thus, blockchain is the solution that best meets all the challenges set out above through the following possibilities :

-The redistribution permitted by smart contracts will, in the very short term, facilitate the introduction of smart grids into current regulations.

-The use of blockchain provides the transparency necessary for trust, and secures the data transmitted thanks to the chosen consensus protocol and the encryption of messages transmitted on the blockchain.

The ability to automate contractualization, reduce intermediaries and autonomously manage distribution makes blockchain the best-suited system.

Networks that combine renewable energy and the sharing economy are multiplying and beginning to transform the energy landscape, while allowing people to take back ownership of energy production and consumption. Blockchain can support this transformation by facilitating all energy production and resale mechanisms, and by creating distributed, scalable mini energy networks. The use of sensors transmitting information to the blockchain and smart contracts, which govern energy distribution and producer remuneration, is revolutionizing the sector. We can imagine applying this to everything from the smallest smart grid to the largest smart city. The circulation of tokens, created when the project is launched, will also enable the exchange of goods and services both locally and internationally.

Providing an automated means of distributing and redistributing renewable energy production and surplus within a network (smart grid type) and between different players, is the tour de force that any smart grid must achieve. Consumers and producers will own a certain number of tokens to keep the system going. The main aim is to enable everyone to benefit from reductions in their electricity bills, and to enable them to choose a renewable energy source, so that they can play their part in protecting the environment. Here's an example of why blockchain is the most appropriate solution for smart grids. During the day, a resident with photovoltaic panels goes to work. In the classic case, without blockchain, the energy produced is not consumed and is sent back to the national grid, but a neighboring school, consuming at full capacity, needs to produce a lot of energy. The resident can therefore choose to distribute his surplus to the neighboring school, and that's where blockchain comes in. Thanks to blockchain, we can program the distribution of energy to entities defined in smart contracts.

The mechanism used to distribute energy from the home to the school, in the previous example, must meet a number of conditions, starting with the accuracy and reliability of measurements, the traceability of flows and the ability to distinguish between exchanges between peers on the one hand, and consumption on the market on the other. The system must ensure privacy, i.e. offer sufficient defense to protect personal information in the event of an external attack. Blockchain meets these requirements and is therefore the best way to improve current smart grid management systems.
