Blockchain Revolution

particular location in the world.
The blockchain also stores all weatherNode transactions. Each weatherNode signs
all of its data with its public key stored on the blockchain. A public key identifies the
weatherNode and allows other entities to determine its reputation. When the node
produces accurate weather data, its reputation is enhanced. If a node is broken or
compromised and produces inaccurate data, it loses status. Nodes with low reputation
receive less bitcoin than nodes with high reputation—the beneficiary being the creator
of the app—whether an individual, company, or cooperative.
The blockchain also allows data providers and data consumers to participate peer
to peer on a single, open system, rather than subscribe to dozens of centralized
weather services around the world, and program their software to communicate with
each of their application programming interfaces (APIs). With smart contracts we can
have a global “WeatherDataMarketplace DApp” where consumers bid for data in real
time and receive the data in a universally agreed-upon format. Centralized data
providers can ditch their proprietary systems and individualized sales efforts, and
instead become data providers for the globally accessible WeatherDataMarketplace
DApp.
