# Exchange A foundational term in the ECSA economic grammar. A simultaneous and reciprocal transfer of objects of value, encoded as a transaction record on ledgers. The practical agreements we make through trade determine the transactions recorded. ECSA is an invitation to understand the economy as a re-designable communication medium and organization system, where our exchanges are not only material but also informatic. This opens exchange as a very interesting design space. See Distributed Exchange Protocol. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
