Ripple

The exchange is adding Ethereum, Ripple, Litecoin, Dash, Monero, Zcash and dozens of other cryptocurrencies in exchange for U.S. dollars.

Stellar, which started as a splinter group from Ripple, has formed a for-profit company called Lightyear.io to help financial institutions integrate its software.

Ripple's distributed ledger platform has fed an appetite for cheaper and more efficient cross-border payments, but it may not measure up to the needs of a larger market. Ripple wants to scale its payment system to something resembling a large card network.

The move is noteworthy because Delatinne had led customer engagement for Swift’s global payments innovation initiative, with which Ripple’s cross-border payment system competes.

Larsen will hand the reins and the CEO title at Ripple over to Brad Garlinghouse, who is currently the company’s president and chief operating officer.
