[JPMorgan Chase CEO admits blockchain has value, but remains skeptical of cryptocurrencies] Golden Finance reported that JPMorgan Chase CEO Jamie Dimon said at the Financial Markets Quality Conference that the bank could be a "big user" of blockchain technology. Although Dimon has long been skeptical of cryptocurrencies and once called Bitcoin a "pet rock," he acknowledged that blockchain has value as a way to "share data and build trust." JPMorgan Chase created its private network Onyx based on Ethereum in 2020 for wholesale payments, peer-to-peer lending and cross-border payments, and has processed more than $700 billion in transactions to date. Dimon pointed out that although blockchain technology is 12 years old, in his opinion, it is still slow compared to the progress of artificial intelligence.
