Whilst I am generally optimistic about the potential application of blockchain technology (and by extension it's financial gains), I do worry a little that it is being oversold as a solution for everything under the Sun, without enough due diligence about whether it is the appropriate solution. At times, it appears that reasonable critics are being drowned out, and we run the danger of only having true believers in the technology not taking heed of warnings from well-intentioned and invested critics.
