Previous Teleport version 3.0 showed good results even on the vast amount of football games audience during FIFA World cup 2018.
However, the data collected since that time has revealed the technology's weak points. So we had to use the chance to improve the Teleport efficiency. Also, the need for the upgrade arose as we develop NODR app, a blockchain-driven version of Teleport solution. Now we are working to unify Teleport for all types of viewers and to simplify switching the blockchain module. This is Teleport v.4.0.
