Blockchain's been here for a long time now, I think we're close to 14 years now but I haven't seen a lot of big changes to it and the technology just keeps on advancing. I think that we should look into projects that are trying to revolutionize Blockchain as we know it and I'm looking at Oasis Protocol and they seem to be promising with their concept of splitting the network into 2 layers: Consensus and ParaTime layers.
