You're In Business

Sunchain is a verified French startup (founded ~2016, Tecsol spin-off) enabling collective solar self-consumption via blockchain. While the project has legitimate pilots (e.g., with Enedis, local municipalities), the submission itself is extremely poor, containing false traction claims ('most people have used my product') and zero metrics. The low score reflects the severe penalty for these credibility red flags, despite the project's genuine technical utility.

Description
Sunchain provides blockchain-based solutions to new use cases of solar energy. We manage local power exchanges between prosumers and consumers. While energy is carried by the physical public grid, it is made possible to buy/sell energy from/to your neighbors or to use this energy remotely, e.g. to charge an electric vehicle away from home. Sunchain’s solution tracks and certifies these flows and transactions.
