====== 2.1.5 Exchange View ======
[[dido:public:ra:1.2_views:1_stakeholder|return to Stakeholder Views ]]

An exchange is responsible for the exchange of information between [[dido:public:ra:xapend:xapend.a_glossary:i:immutable|immutable]] [[dido:public:ra:xapend:xapend.a_glossary:d:data_object|data objects]]. An exchange can be wholly contained within a domain, act as a [[dido:public:ra:xapend:xapend.a_glossary:b:bridge|bridge]] between domains, or even span across ecosystems or ecospheres. Obviously, the complexity of an exchange increases as the range of what is exchanged moves from just internally within a domain and crosses ecosystem or ecosphere boundaries.

An exchange is a process that exchanges one kind of immutable data object for another. [[dido:public:ra:xapend:xapend.a_glossary:b:bitcoin|Bitcoin]] would not be worth much if there were no way to exchange it for existing currencies such as euro, dollar, etc. Exchanges may be completely contained within a DIDO community network or act as the bridge between networks within the community; or be used to transfer immutable data objects between communities (i.e., Bitcoins to [[dido:public:ra:xapend:xapend.a_glossary:e:ethereum|Ethereum]], Iotas, or commodities such as gold, silver and grains).

An example of an exchange that could operate completely within a community might be for customer rewards programs that include customer loyalty reward programs.
