Hi. I'm the author of the article. Thanks for your interest. I'm glad the piece is sparking a deeper discussion of the technical trade offs of the technology.

I just want to clarify that this article is one of many included in a full Spectrum issue dedicated to blockchain technology, which I had a hand in organizing. From the outset I was adamant that we acknowledge the costs and limitations of blockchains. Part of that treatment can be found in the last half of the overview.

But we also try to hit those notes in a separate piece, which you can find here.
