**Iota** is an [[dido:public:ra:xapend:xapend.a_glossary:o:oss]] [[dido:public:ra:xapend:xapend.a_glossary:d:dlt]] and [[dido:public:ra:xapend:xapend.a_glossary:c:cryptocurrency]] designed for the [[dido:public:ra:xapend:xapend.a_glossary:i:iot]]. It uses a [[dido:public:ra:xapend:xapend.a_glossary:d:directed_acyclic_graph_dag]] to store [[dido:public:ra:xapend:xapend.a_glossary:t:transaction | Transactions]] on its [[dido:public:ra:xapend:xapend.a_glossary:d:distributed_ledgers]], motivated by a potentially higher scalability over blockchain based distributed ledgers. **Iota** does not use [[dido:public:ra:xapend:xapend.a_glossary:m:miner | Miners]] for its [[dido:public:ra:xapend:xapend.a_glossary:c:consensus_process]] for validating transactions, instead, [[dido:public:ra:xapend:xapend.a_glossary:n:node | Nodes]] that issue a new transaction on the network must approve two previous transactions. Transactions can therefore be issued without fees, facilitating microtransactions. The network currently achieves consensus through a **Coordinator Node**, operated by the Iota Foundation. As the coordinator is a [[dido:public:ra:xapend:xapend.a_glossary:s:spof]], the network is currently centralized.
