SCP is technically reliable Byzantine consensus practice for blockchain and its respective contracts with a contract or blocks in terms of epochs, here, every epoch makes a target then decision based on available rules. The principle idea of SCP efficiently utilizes the existing computational power. It separates existed computational powers into sub-groups, where every group works on an existing algorithm to agree on a solitary result. In SCP designed algorithm, the processor completes five phases in every epoch; in the first step, with the help of the local computation virtual committee identifies a processor. In the second step, processors try to recognize remained processors implicated; in the third step, processors execute on an authenticated procedure to consent on a value. In the fourth step, final consensus algorithm validation and ending value from each spread. In the fifth step, distribute random generation for virtually independent random assessment.
