[AUDIENCE] Excellent analogy. Do you see the 14 nanometer transistor limit as being…a good or bad thing for decentralization?[ANDREAS] I think it is a really good thing. To repeat the question, do I see the 14 nanometer transistor limit-We have seen an enormous increase in the hashing capacity of Bitcoin’s proof-of-work network.It has been catching […]
