A partially decentralized video streaming service. It has nice, polished user interface. It runs on a blockchain. Monetization can be done with their cryptocurrency. While reviewing this service, note that the confirmation link sent to my email address did not work. When clicking it, it went to their site, but showed a blank page with only "Invalid Request" shown at the top. This may be because my email address has a "+" sign in it and many developers incorrectly treat the "+" sign as invalid. The URL in the e-mail had my email address in it, so I modified the URL to use the HTML encoded version of the + sign, which is %2b, which also did not work.
Streemie might not work without centralized DNS.
It might not work without central servers.
It's unknown or not applicable as to how user accounts are handled. Monetization is uncensorable and unstoppable with cryptocurrencies.
