Traffic data in cities is a gold mine for many public and private actors to **improve their decision-making** processes based on data and more globally to improve **citizens' quality of life**. For public services, this kind of data could allow them to ensure a **better mobility service** according to the data flow collected and enhance the works on roads or measure the impact of traffic on the **environment**. 

It is also a godsend for **emergency services** and the police who will be able to better coordinate their actions accordingly. On the private side, several types of targets can be identified, ranging from **real estate**, **transportation** and **advertising**. For merchants and big brands, this type of data will allow them to have a complete mapping of the streets of a city and their **degree of frequentation** in order to choose the right place to establish a business. The real estate sector can also benefit from this by allowing to calculate rents on a **numerical basis**. As for transportation, the analysis of flows will allow them to avoid or anticipate **traffic jams**. 

Finally, for **advertisers**, it will be possible to quantify the impact of **street campaigns** just like online advertising impressions. Currently, this type of data is very **expensive** or **unreliable** because it is either a very expensive specific project with a **limited duration**, or the data is collected via **GPS/Bluetooth/Wifi**, which is not always fully representative because a part of the **data is missing** and requires an extrapolation via statistical models. Indeed, the GPS, Bluetooth and Wifi service providers do not give access to their data for obvious **privacy reasons**.

2Blox aims to collect its data through its community. Everyone will be able to "**monetize**" the traffic in their street by simply installing a sensor that will analyze the **type of users** on the road and compile it all in order to aggregate it on an **exchange platform**. The project is composed of several elements: the **sensors**, the **MOBI™** **OS**, a **web application**, the **decentralized network** and the **data exchange** place, 2blox Ex.

2Blox does not aim to be the exclusive manufacturer or reseller of any sensor model, hardware companies can become approved to provide **hardware** that meets **data** **quality**, **privacy** and **security** requirements. All equipment must be able to host 2Blox's proprietary OS which ensures that the requirements are met, and to prevent program modification, a **Code Integrity Checker** (CIC) will produce a **public validation key** to certify the **integrity** of the **sensor**. the OS will communicate with the user's wallet on the blockchain to identify itself as a **data provider**. It is via this wallet that he will also be able to collect his **rewards**. At the installation level, the sensor is attached to a support (for example a window) overlooking a **counting area**. The embedded OS will validate that the counting area is **well** **conformed** (depth of field, obstacles, visual noise...). 

Finally, the user will have to fill in the counting area by inserting the address containing the **name of the street** that will be covered. Each sensor will have a **geographical position** declared by each user and its data will be cross-referenced with the coordinates of the different Wifi access points in the vicinity thanks to the **Probe RSSI method** (or another method such as AoA) in order to validate that it is the right address. In case of inappropriate behavior regarding the location of a sensor, the **rewards** **will be blocked** until the situation is clarified.

In order to validate the identity of a data provider, he will have to purchase a **license** in the form of an **NFT** that will be present in his wallet as an **authentication token** to receive the rewards. Each license has a **defined** **duration** and can be linked to only one sensor at a time, they will have to be renewed in order to continue to receive the rewards.

Once the sensor is installed and the provider is **certified on the network** with its user wallet, the data can be **collected** and **stored** on the **blockchain** in order to be aggregated and then **resold** on the **2blox exchange**. The data is pushed to the blockchain once a day and per sensor at random times so as not to cause network congestion.

The **community** supports the **investment** in covering cities with sensors. The first step is to deploy the minimum coverage to make the project viable by its amount of data. Once the coverage is large enough, the data becomes **monetizable**.
