I had no idea what this is, and to help others who feel the same way, here is a bit of info I picked up from the web:

Tachyon Protocol is a decentralized Internet protocol built on the V SYSTEMS blockchain. It is utilized for building a trusted, stable, fast, reliable, and transparent digital connection.

It merges the benefits of blockchain, user datagram protocol (UDP), and encryption technologies to achieve high security, obfuscation, availability, and maximum network speed.

The alpha version for the first Tachyon VPN product on MacOS was recently launched, and the iOS and Android clients will be released in Q1 2020. Moreover, V SYSTEMS has announced that its staking initiative for the IPX token will start this December.
