Local Exchange Trading Systems (LETS) are community-based networks that allow members to trade goods and services using a local currency. Instead of traditional money, participants earn credits by providing services or products, which they can then spend on offerings from other members. This system promotes local economic activity and strengthens community ties. LETS operate on the principle of mutual credit, where transactions are recorded in a central ledger. This means that members can trade without needing to find a direct exchange for their goods or services. Such systems can enhance social connections and support local economies, reducing reliance on conventional financial systems.
