A **Node** is an individual computer that participates as an equal within the [[dido:public:ra:xapend:xapend.a_glossary:n:node_network]]. A node is sometimes referred to as a **peer** within a [[dido:public:ra:xapend:xapend.a_glossary:p:p2p]] network. Nodes receive input, perform one or more operations on those inputs; and returns an output.((Not all DIDOs use "mining" as originally defined in Bitcoin as Proof of Work (PoW) and they may not need a full set blockchain transaction to verify transactions.))
