MODO COIN is already working with Bank of America Merrill Lynch, Verifone, FIS and Klarna !!!!
The COIN has similar functionality as blockchain. It is a quick integration to existing systems and their ledgers, rather than an overhaul to a new model.
The payments hub, COIN, is designed to power digital payments from any two sources without either party having to modify their payments systems.
It all comes down to simple accounting and communication. The ledgers must be in sync along every step of the payments lifecycle in order for a transaction to progress through the COIN.
For any payments transaction, both sides of the transaction must agree to the rules for those transactions. The COIN makes sure that before money is moved, the rules between those parties have been adhered to.
If Modo cannot get everyone to agree on the state of play at any point in the transaction, the COIN will stop the transaction in its tracks until a resolution is found which often is automated.
