A storage node is a machine connected to a decentralized storage network that stores pieces of other people's files and returns them when they are requested. The term is used most prominently by Storj, where independent operators run storage node software on their own hardware, from home computers to professional servers, and are paid for the space and bandwidth they provide. Files are encrypted and split before they reach any node, so an individual operator cannot read the data or rebuild a whole file alone. The network checks nodes for uptime and data integrity, and nodes that perform poorly earn less or are removed. More generally, a storage node is one type among the different kinds of nodes in blockchain systems, alongside full nodes and validators. Also see storage miners.
