Exchange systems

Exchange systems are frameworks that facilitate the buying, selling, or trading of goods and services between individuals or entities. These systems can be found in various forms, such as markets, online platforms, or barter networks, where participants agree on the value of what they exchange. They enable efficient transactions and can operate using currencies, credits, or direct trade. Examples include traditional marketplaces, stock exchanges, and digital currencies like Bitcoin, all designed to enhance economic interaction by providing structured means for negotiating and completing exchanges.
