While Jamie Dimon has long derided digital currencies, JPM has teamed up with the creators of one of the most prominent "altcoins", ZCash, to build privacy features for the bank's blockchain platform for smart contracts (Quorum). Quorum was designed so that a smart contract would be visible only to the parties, not the whole network.
Applying that technology to Quorum would allow tokens (representing real-world financial assets, say, shares in Apple) to circulate throughout the network, rather than be confined to bilateral agreements between banks, without sacrificing privacy. “By adding the zero-knowledge security layer into Quorum, we are able to explore how state of the art cryptographic privacy technology will enhance the next generation of financial services applications,” Suresh Shetty, an executive director and lead architect for JPMorgan’s Blockchain Center of Excellence, said in a press release Monday.
