Swarm City provides the tools necessary for anyone to create decentralized marketplaces where users can find each other, communicate and exchange value safely. By avoiding third party trust administrators, Swarm City uses blockchain technology to lower administrative fees and build trust with every successful transaction. According to Matthew Carano, Swarm City provides a platform to facilitate the basic human need to collaborate and obtain the best possible outcomes. Blockchain technology eliminates the need for third parties because Swarm City uses a blockchain reputation component that issues non-tangible reputation tokens to users after each successful transaction. The marketplaces are created and owned by users. Users benefit from blockchain transparency that allows users to transact safely with the use of smart contracts. Each smart contract is marketplace specific and helps build communities of like-minded users to benefit economies of scale.
