> This is trivially falsifiable: blockchains are being used to facilitate illegal transactions. There are other mechanisms for facilitating illegal transactions, e.g. the Hawala network. So the blockchain is at least not the single mechanism for this. And if we're really precise, the blockchain itself doesn't solve this particular problem. It solves the trust problem, just like Hawala.
