iExec participated in the 2019 edition of Mobile World Congress in Barcelona. It was a fantastic opportunity to get an insight into groundbreaking technologies that are going to enter the global market over the next few years. It was also the occasion to showcase our latest advancements in 5G, Blockchain, and IoT.

Mobile World Congress is one of the leading tech conferences in the world, the largest mobile event, often considered as Europe’s answer to the annual CES convention in Las Vegas. MWC 2019 took place in Barcelona over three days from 25th to 28th February. The conference gathered more than 100,000 visitors from around the world, including over 2,500 exhibitors from the most innovative sectors, some of which unveiling leading edge-technologies to a public audience for the very first time.

The global theme of the 2019 edition of the conference was ‘Intelligent Connectivity’, with a focus on themes like A.I, Industry 4.0, Immersive Content and Disruptive Innovation. The event offered opportunities to learn from the best, featuring dozens of partner-led programmes, seminars, and summits surrounding these topics.

iExec showcased a demo in collaboration with Intel®

iExec exhibited their new at the Intel® booth gained attention from key industry leaders and decision makers as well as from the media. The topic was ‘How smart cities could benefit from 5G and Blockchain’. The demo showcases two robots lost in an unknown zone of a city. A rescue service can be easily discovered and triggered via the iExec blockchain-based platform: the rescue robot is then sent to the unknown zone before a third robot is sent to help them to come back to their base. The rescue robot generates a map of the unknown area, using it to discover the lost robots, before leading them to a safe destination. A proof of the rescue service’s success can then be recorded on the Blockchain and to automatically trigger a monetary exchange associated with the Blockchain transaction. For this kind of smart city service, an authorized person uses iExec to trigger, monitor and validate the entire rescue task and the result.

The exhibit of the 5G and Blockchain use case was a huge success for iExec. Being associated with Intel®, a historically leading actor within the industry, , put iExec in the spotlight. Hundreds of companies came by our stand, curious to learn more about 5G, blockchain and TEE (Trusted Execution Environment). iExec were able to show how its end-to-end TEE solution (using Intel® SGX), and blockchain technology, can provide solutions to allow dynamic networks of devices connected by 5G to for smart city solutions.

iExec was classed as the third most visited booth out of all the 30 within the Intel® 5G hall during the MWC conference. This was counted by the number of people who scanned their MWC badges to share their contact details, making them potential collaborators or users of iExec technology in the future.

Why will smart city services need iExec

iExec technology will address three major challenges faced by 5G connectivity.

→ The service provided by iExec’s Blockchain based marketplace allows clients to easily discover the 5G based smart city services.

→ The authentication procedure between the rescue robot and the trapped robots should be secured. iExec’s TEE solution powered by Intel® hardware-based security (Intel® SGX) makes the process fully protected from any potential threats that could be for example, wrong and potentially dangerous information sent from a malicious robot. It also makes sure that we keep a trace of what has been exchanged between the robots.

→ Finally, blockchain will ensure that both parties will pay and receive the money for the task that the robots just did. Payment and reward are necessary are exchanging services. Where 5G is the communication layer, blockchain is the Interoperability layer.
