Thank you for the question! Public blockchain platforms suffer from serious scaling and performance issues. To enable highly scalable, low latency, and cost-effective fully decentralized systems and to eliminate the need for semi-centralized approaches, significant future advances will need to be made in blockchain technology. Projects such as TrueBit, the Lightning/Raiden networks, IPFS and Filecoin, Mysterium, and IOTA are steps in that direction. But these are merely the precursors.
