Blockchain has gained a lot of interest within the last years because of its transparency and immutability. This also helps a lot about the IoT economy to rise. Ethereum Blockchain gives a more secure place when compared to traditional systems against hijack and botnets. Developers are using Ethereum smart contracts for their aims. This is in result helping IoT devices to work with smart contracts with automated tasks.

Ethereum and IOT: Blockchain-driven data streaming 

Everyone is on the same idea that Blockchain is more democratic according to traditional systems. Blockchain-driven data streaming platform Streamr provides decentralized means for just about anyone to buy and sell data. The platform allows data owners to easily connect to the peer-to-peer network and stream their data, the access to which others could readily purchase. Streamr’s marketplace uses blockchain smart contracts and tokens to facilitate transactions and incentivize data exchange respectively. According to a latest article published on Forbes, Cofounder and CEO and of Streamr Henri Pihkala says “For optimal operation, it constantly needs data from other machines, such as traffic congestion information from other cars, electricity prices on nearby charging stations, weather forecasts, and so on. Streamr provides a single interface for real-time data delivery and payment, making data streams tradeable by people and machines using the cryptographic token called DATA coin which lives on the blockchain. The car can autonomously get the data it needs and pay for it. In turn, the car can sell the data it produces, such as traffic data to other cars, road condition measurements to a smart city, location and battery level to advertisers, and so on. A data stream economy is born.”.
