Everpedia the censor proof encyclopediaThe problem with Wikipedia from a moral standpoint is, that they wish to democratize information and let the masses use as they please. However, authoritarian regimes either block wikipedia access like China or another country like Turkey block only sections. The reason why they can do this is because Wikipedia must be the owner of it data, store it in a central database and comply with local governements or not do business. Everpedia meanwhile plans to crawl Wikipedia for articles which is allowed under their creative common license and users generate own unique articles as well. Since Everpedia stores its info on a blockchain as it expands government can't request Everpedia to censor because they do not have direct control over their information like that thus, they can physically not comply.
The perfect ID systemBlockchains are great and storing accurate information. A democratic society such as Estonia a small nation has used the blockchain for voting, holding ID cards, and other government needs. Estonia is one of the most organized bureaucracy. People can do their taxes in less than 15 minutes, government is efficient WHAT COULD GO WRONG ?
