Unlike the Internet, the Blockchain consists of millions of individual computers around the world. These computers run sophisticated software which contribute data processing, computing, energy and connectivity to support blockchain applications, securely store data and confirm transactions.
Nodes are owned and operated by private individuals, small and medium sized businesses and others. Node operators are compensated for their contribution to the blockchain. Sophisticated blockchain software confirms each node is in operation and providing the resources to support the network and perform functions.
Blockchain Nodes are software applications that individuals install and operate on their personal computer, mobile device or other Internet enabled devices.
