Imagine you want to provide a service, such as cell phone service, in a developing country such as the Republic of Chad. Many users of your service may not have access to the banking system. Your business model may include, in addition to the cell phone service, providing electronic money transfer and payment services. The task is to develop a stablecoin cryptocurrency to facilitate the electronic transfers and payments, including payment of the users' cell phone bills. As a stablecoin, it will be backed by a currency or other financial instrument like government bonds. Consensus will come from trusted nodes using a Byzantine fault tolerant algorithm. To make building cell phone applications easier and to avoid unnecessary payments to other cryptocurrency miners, the underlying blockchain should be based on Hyperledger Iroha.
