What is the value in this project? If the purpose is to let X make statement Y and prove did X said Y and only Y, there are at least five more prevalent standards to do so ranging from other blockchains to web sites/archiving, DNS records, various archives across the world, etc. We can make the QR example work today with a URL. All these mechanisms are much more likely to survive longer than the suggested project, and are less subject to Proof-of-work energy waste. That leaves the voting mechanism, which isn't very useful either - truth isn't subject to majority vote.
