I remember random recruiters talking me into speaking with 4 blockchain companies for remote gigs. I had a hard time understanding the value proposition and asked the founders types of questions like, why is this knowledge base better than stack overflow or why does this rating system work better than other systems? It came down to answer the question because "blockchain blah blah". Not giving the actual value to the consumer. It was more touting what the technology allows rather than real value. The killer app of blockchain is crypto currency at this point IMO. Not much else but I'm rooting for Vitalik as that dude is a genius and I still feel like something amazing will come out of his work. I would guess if you are going to use blockchain for something, make it something that cannot function without it and is one of a kind in being a new thing that people will want, not a clone of an existing tech + blockchain.
