Despite the seeming variety of instant messengers, there are practically none for everyday use. The following points must be fulfilled (mandatory minimum):

• voice
• text
• the availability of ready-made assemblies for the main mobile platforms - Android and iOS
• reliability and stability of work
• work out of the box and must be free, so that there is mass adoption (no complicated settings, no need to run your own special servers, etc.)
• no third party control of data and metadata

There are many interesting projects, but there are practically no instant messengers that work stably and are private:

• Safeswiss is good in all, but it is a centralized system that collects the most detailed user logs
• Briar is reliable, but there is not and will not be voice communication
• in Jami and in Element, the reliability of work is low - messages and calls do not pass regularly, even if the interlocutors are obviously online; therefore these systems are suitable, in my opinion, only for experiments
• Tox is a good idea, I tried it for a long time, but I remember Antox somehow worked, and Antidote was junk, I had to look for alternatives. These applications have not been finalized and are not being developed now.
• and so on...

You got off to a great start. I am testing the application. Impressions are very good. Basic functionality works stably, and this is very important.

Some questions:

• will the code be open?
• what server services are used in the system? (at least certainly exists bootstrap server)
• how is the delivery of messages ensured if both interlocutors are not online at the same time? It works, and it's great, but not clear how. (through blockchain?)
• the feedback form on the site does not seem to work 'We were unable to process your request. Please try again later'

Improvement suggestions:

• self-destructive messages with adjustable deletion time, for example, as done in Safeswiss
• dark theme
• upgrade tech descriptions and white paper; some points are out of date and some are not reflected
• roadmap for 2021-22

Будьте осторожны!
ТС впаривает какие-то гнилые ссылки. И соответственно скачаете с них вирусню. Или скрытый майнер.
Линк настоящего сайта Mediacoin:

Вижу противоречие в описании. На главной странице сайта читаю:
"Без цензуры"

и чуть ниже, в дорожной карте:
"Q2 2020
Система модерации на основе пользовательских оценок Пожаловаться"

Т.е. модерация (= цензура) и удаление файлов все-таки будет? Или же только будет снижаться рейтинг "плохих" файлов? Представляю себе какие войны развернутся на политическом контенте.

И второй вопрос: там есть какая-то система поиска в сети?

What happened to NEM (XEM)? Why did it disappear from the list? Thank you for your reply.

Would you name your baby BCNext for 150000 NXT?   If seriously, my answer is no in any case.
