> Blockchain enables value-transfer, what is that in plain english? Money. A digitally-signed email enables value-transfer too. Depending on your risk profile you could even go for an authenticated TLS connection that just does a RESTful style POST to enable value-transfer. Value-transfer is not unique to a blockchain, or to Bitcoin's blockchain in particular, any more so than bubble sort is the only possible implementation of a sorting algorithm. CS majors know to avoid bubble sort because it is so inefficient, yet many refuse to apply the same lesson to POW-based systems like Bitcoin.
