Mutual Credit Clearing

Protocolo Monetário Descentralizado

A monetary protocol in which participants extend credit to one another bilaterally through a shared ledger maintained by a third party, with the sum of all account balances structurally constrained to zero. Each transaction simultaneously credits one party and debits another. Prototypes: Sardex (Sardinia, Italy) for institutionalized B2B mutual credit; Local Exchange Trading Systems (LETS) for community-scale implementations.
