Why blockchains fail and decentralization succeeds

GUEST: With all of the excitement around blockchain technology, it’s easy to think what we have now is the foundation for the next wave.
Yet, it’s worth remembering we are still in the early stages. The blockchains we have today probably won’t be the blockchains of tomorrow.
I am still bullish on Bitcoin (for reasons that go beyond this post), and Ethereum looks promising. It also has a lot of technical questions that surround it.
