Notes
Virtual Video files “Ledgers”Contain transaction, Authorization and video frame sequences from single or multiple video files
12 VDNA is kept at a controlled location and deliveredwhen the Content Blockchain reaches consensus.Virtual Video “ledger requests the VDNA on press of Play, and virtual video interprets incoming VDNAto play video.Seperating the components of a video file into the blockchain and providing access only when the chain reaches consensus allows all the benefits of Blockchain security but with the added benefit of Ai or data driven content programmability via the custom assemble of VDNA blocks or sequences.
