What means of IOT Devices & Mining ?
It is a challenge to integrate smart contracts with oracles that serve as authenticated data feeds. Nodes must be able to independently verify an oracle’s consistency. We study Crux: Locality-Preserving Distributed Systems for optimizing routing and for exposing network topology. The former is useful for sharding that respects physical distances.
The latter can take the GPS signals of mobile or IoT devices as proof of location in our applications. With tight integration of locations, Dencities will be well-suited to support applications for smart cities. For example, autonomous vehicles can fetch verified location data in upcoming trips. Or, imagine thousands of swarm robots, self-organizing around a common mission in an unknown terrain.
Maps for geocoding and points of interest can be a showcase for decentralized applications in the real world. A good starting point for building decentralized maps on Dencities can be augmented reality games with incentives like Pokémon. The competitive advantage of decentralized maps is the long-tail, community-specific content. For example, a school can mobilize all of its staff to map out its buildings and playgrounds in a day; any student or organization can then build games and events on top of the location data without coordination.
Dencities will also serve as a high-volume data marketplace and optimize its machine learning performance. We follow Blockchain-based Machine Learning Marketplaces to build a new decentralized economy based on data. The key aspects are privacy-preserving applications and transparent data usage. The effectiveness of multiparty computation and homomorphic encryption relies heavily on high performance platform such as Dencities.
With JejaQ we introduce decentralized data and node storage in combination with token earning/mining. We will offer users across the globe the possibility of cooperating with Dencities by offering their free storage space for the decentralized storage of Dencities blockchain nodes and certain data to be stored, especially scientific and research data. By offering data space to the Dencities network the participating users earn Dencities tokens and thus make Dencities even more decentralized while incentivizing the participating users for their cooperation.
The more users participate, the more decentralized Dencities will be. A complex mechanism will make sure that all data and blockchain information will be available at any given time, even if users lose their smartphones or the access to it. The Dencities blockchain protocol will be adapted to the new functionality in 2022 and the roll out will happen until the end of 2023. Besides the user’s individual data will be directly stored to the users’ smartphone to make it available via USB in case of no internet connection.
