Why is Vidya.io server used.

Why can't Moodle or php scripts be used?

Moodle/php if used would be very slow and would demand lot of resources. Ever tried running Moodle's chat module with many users? You would also notice that Moodle recommends a chat daemon to run to reduce load on server. Even after daemon, it is slow. This is not Moodle's fault, it is way how PHP is, it is not correct tool for job.

1. vidya.io server using secure SSL certificates and works only with secure protocols. This is security used by everyone for online credit card transactions. It is secure.
2. No data is read by any human, vidya.io transmits information from one user to other connected users and that's it.
3. No data is ever saved on vidya.io servers.
