I wrote about the blockchain paradox – about how blockchain doesn’t meet its design goals – back in 2017. I’ve illustrated this article with the border between Northern Ireland and Eire. In 2018, the then chancellor of the exchequer of the UK, Philip Hammond, said he thought Blockchain might be a solution to the Brexit-related problem of avoiding a hard border between the two countries. It isn’t. Technology in itself is never a solution to a problem of human affairs – much less a flawed technology like blockchain. And yet people keep advocating for blockchain as though it is.

I gave talks about Blockchain for Sceptics in 2017 and 2018. Here are some slides from those talks, which are complementary to the discussion in the blog post. The links in the embedded PDF aren’t clickable. You can download the PDF with clickable links here.
