Blockchain And The City

Blockchain And The City

Organized by the Trusted IoT Alliance, the Blockchain and the City Challenge was designed to address use cases for decarbonized mobility and urban life. It was a follow-up to the Smart E-Mobility Challenge that concluded in May 2019.

The Challenge was championed by a group of eco-responsible, innovative companies, local communities, public services, and blockchain technology-oriented organizations who were active in the City of Lyon, France.

The Challenge featured two workshop/hackathons staged at La Ruche Industrielle, an innovation hub in a former Bosch Rexroth factory in Venissieux (outside of Lyon). Winning teams received a cash reward and a Proof of Concept to be staged at LaRuche.

About The Challenge

The Blockchain and the City Challenge focused on blockchain-based use cases for urban transportation, urban industry, decarbonized mobility and the various other related use cases combining blockchain, IoT and city life in large metropolitan areas.

The main goal of the Challenge was to jointly develop solutions that provide real world value-add to the many aspects of city life in the near future, including services for city life.

The Challenge was designed to enhance the journey of an inhabitant of a large city anywhere in the world (such as Lyon) in an attainable near future. This inhabitant will commute with multimodal urban transportation means, including smart parking, smart charging services. He or she may work in a typical working day in a light industry urban factory, a fablab, a repair shop, a logistic service, and so on.

The Challenge looks at a complete journey, and the infrastructure levering it. The context for constraints and attributes of city life in the Challenge are as follows:

  • Priority to share transportation means
  • Priority to decarbonize energy in urban daily use
  • Traceability of energy purchases
  • Multi-modal transportation with one pass
  • Multi-service for urban life with one pass
  • Availability of 4G and 5G networks
  • Light industry and fablabs disseminated in the city
  • Urban logistics
  • Availability of hardware and software to connect various machines, tools and objects to Blockchains and DLT

The Challenge Infrastructure

The Challenge infrastructure is typically a set of decentralized marketplaces or data hubs, which can be used by different stakeholders according the requirements outlined above. It is important that the means of onboarding new partners are simple. In particular, they should not require the use of complicated and advanced APIs and data structures. They should fit in well with MS Excel-like data transfer mechanisms and with typical IT environments, including corporate firewalls and VPNs.

A number of interesting use cases can be built on this core infrastructure. For example:

  • Collaboration
  • Privacy and security: Ensuring citizen privacy and security safety
  • Smart urban environment: smart parking
  • Urban logistics such as last kilometer delivery and track and trace of materials and vehicles
  • Multimodality for urban transportation
  • Others

Key concerns for all use cases: Connection of blockchains and things, ID management, confidentiality of privacy and commercial data, assessment of environmental and societal impacts.


The following Use Cases are "living," which means they are constantly evolving. They are designed to spur ideation and innovation as the Challenge moves forward.
