Freebase (database) - Wikipedia

Freebase was a large collaborative knowledge base consisting of data composed mainly by its community members. It was an online collection of structured data harvested from many sources, including individual, user-submitted wiki contributions.[3][2] Freebase aimed to create a global resource that allowed people (and machines) to access common information more effectively. It was developed by the American software company Metaweb and run publicly beginning in March 2007. Metaweb was acquired by Google in a private sale announced on 16 July 2010.[4] Google's Knowledge Graph is powered in part by Freebase.[5]

Wikidata is a wiki powered by the software MediaWiki, and is also powered by the set of knowledge graph MediaWiki extensions known as Wikibase.

Helium network: IoT blockchain / cryptocurrency

This house comes with a built-in cryptocurrency miner. : Planet Money : NPR

The Helium Network is a decentralized wireless Internet of Things (IoT) network using the LoRaWAN system, tied to the cryptocurrency Helium Network Token (symbol HNT).[1] Nodes on the network are generally owned and placed by individuals in their homes or offices, and they are rewarded for their participation in the network in payments of HNT.[2] The network aims to provide connectivity to IoT sensor devices in areas where wireless or mobile coverage is minimal, or requires too much power.[3][4]
