J.P. Morgan Chase (JPM) CEO Jamie Dimon was on CNBC a short while ago talking with hosts Andrew Ross Sorkin, Joe Kernen, and Becky Quick from the sidelines of the Davos conference and had some bullish things to say about the digital ledger technology variously known as “The Blockchain” and “blockchain."

Asked by Ross-Sorkin about the virtual currency bitcoin, Dimon dismissed it, shaking his head and saying that if it had any momentum, global authorities would step in to block it.

In contrast, he said The Blockchain is something that has broad applications to commerce and banking:

The blockchain is a technology which we’ve been studying, and yes it’s real, it can probably reduce the cost of doing business. If it proves to be cheap and secure, it would be adopted for a whole bunch of stuff.

Dimon was also asked about Apple’s (AAPL) Apple Pay, and was upbeat, saying "they’re going to be adopted more, but only so many people have NFC,” the wireless transfer technology used to implement Apple Pay and Alphabet’s (GOOGL) “Android Pay."

"I think you’ll see more of this stuff get used,” he concluded.
