Bitcoin Evolution with Segregated Witness by Oleg Andreev

This is better version of original talk made by Oleg Andreev, given in February, which was recorded with not the best audio quality, it was simply too much of the background noise.
All the credit still goes to Oleg and Bitcoin fr who organized the talk.

Changes:

• I extracted the audio from original youtube video, processed with Audacity (noise reduction) and merged it back.
