This project is a symbolic benefit to the Ethereum blockchain needed to strengthen data chronology through the credit protocol. The Blockmason project allows the borrower and the bank to exchange on the equivalent blockchain with a credit protocol. Thus, it is very easy to put funds or bring cash flow in developed air. The Credit Convention, or BCPT, is a framework used to continuously record records of commitments and advances between parties using the Ethereum blockchain. Ensures the development and unchanged quality of the submitted records. Similarly, it is proposed to approve a certain important agreement, for example, the approval of loans by genetic assemblies and the approval of cryptographic notes by the parties to the contract. In addition, people who take advantage of the project's loan agreement purchases can be reminded of the coin chain and provide cash flow. The platform is also used in a variety of unique smart contracts, such as credit protocol data collection and contracts, court powers, and Flux condenser contracts.
