With the help of blockchain technology we solved two current issues - the problem of individual trust among the members of the community, and the problem of trust for blockchain projects. We developed a reputation system for members of the community and the projects themselves. The reputation scores are stored on the blockchain and cannot be changed by any party.
Keeping reputation on-chain is necessary for further calculations of the reputation in case of disputes, and distribution of rewards as a result of contribution to the community. Interim reputation calculations are transferred to the off-chain / sidechain to guarantee the scalability of our system.
The process of selecting a miner is similar to the process of selecting the validator in PoS implementation of Casper, the more frozen steak (T) at the time of the start of the process of selecting a random miner, the more likely it is to get the opportunity of validating and recording a block in the main blockchain.
