Thanks a lot for your support. I'd like to take the opportunity to elaborate it a bit more, hopefully encouraging the community to give it a try.
The proposed community-based credit/role system for peer review could be implemented either on large preprint servers or on dedicated review platforms. Most existing services and platforms, including the most recent ones, either lack incentives or do not provide the right incentives - the monetary/honorary incentive some of them have used does not really work for reviewers. The best incentive, in my opinion, is to increase their role in the community in exchange for their quality review work. This will motivate most scientists to review each other's work more.
In addition to the right incentives, such a system could actually make the platform financially self-sustaining. For example, they can receive donations or fees by helping overlay journals on peer-reviewed preprints; by assisting funding agencies, especially private foundations, in reviewing proposals; by providing academic institutions with more reliable merit evaluation of candidates for their hiring and promotion decisions.
By gradually implementing the system from paper review, proposal review, to achievement evaluation, the credit/role system will eventually make the implemented platform the most attractive one for all scientists and researchers, especially the up-and-coming young ones. The most important factor for the growth of a platform is the size of its user base. This will do it. In addition, a successful platform could further expand its scope, for example, in the business of organizing conferences (for example, determining topics and who should be invited), and reviewing proposals for experimental facilities, etc. That would be a dream come true for me.
Regarding the downsides, I have received criticism against a quantitative system that I should defend a little more. The development of science itself is an evolutionary process of becoming more and more quantitative and rigorous. If we never try to make a field more quantitative, then it stands no chance of becoming part of the science. I dare to propose an initial endeavor to quantify measures that could be applied in peer review, in the hope of establishing a first quantitative paradigm for peer review. It would be a pity if rigorous science could not be assessed in a quantitative manner.
