The CREDITS platform is an example of how a system that has abandoned the system can create a secure decentralized environment. Its security is provided by mixed consensus algorithms mDPoS and BFT. This algorithm allows you to order the nodes of the block-network, which are allowed to vote. The node takes part in it if it can confirm the relevance of the software and the locally stored registry. Also, each node can become trusted or principal no more than once in a certain period of time. This ensures decentralization of the network. Due to the absence of a permanent ‘leader’ in the system, security is ensured. For example, decentralization does not allow you to intercept and change a transaction while it passes through the network, because of the constant monitoring and analysis of incoming transactions to the network from different sources.
