This hackathon is about building a Citizen Web that would collect data in a crowd-sourced way for everyone’s benefit. The open source Nervousnet platform is trying to offer a participatory platform allowing everyone to collect data, mine data, and create their own Internet of Things app. The Hackathon is trying to connect Nervousnet with LoraWAN and The Things Network with a comfortable software platform and Blockchain technology (for security, privacy, and decentralized control, pluralistic payment and incentive systems, smart service contracts, ...).
