I'm surprised at this being such a painful problem and no one jumping forward to solve it (pardon my ignorance, if such startups exist but are not well known, I wouldn't know it). Why wouldn't blockchain db for receiving and requesting p2p reviews not a good solution? This journal can be open access and still make boat loads of money on allied services, ads and so much more. The best part, most of this can/needs to be automated leading to super low costs of operation. Am I missing something obvious here?
