Six largest cryptocurrencies by market cap
CoinMarketCap charts show ripple had climbed above ethereum into the second-place spot in May. But back then ripple was only worth about 36 cents.
The digital currency ended 2016 at less than 1 cent and topped $1 only last week, before leaping above $2 Friday afternoon. Ripple is up more than 34,700 percent this year.
Ethereum rose about 2 percent to $753.57 Friday afternoon, with a market cap of about $72.8 billion, according to CoinMarketCap. Bitcoin traded slightly higher, near $14,475, according to Coinbase.
Ripple is officially the name of a San Francisco-based start-up using blockchain technology to develop a payments network for banks, digital asset exchanges and other financial institutions. Network participants use a digital coin called XRP for transactions. The cryptocurrency has a four-second settlement time, versus more than two minutes for ethereum and over an hour for bitcoin, according to Ripple's website.
The company said more than 100 financial institutions use its network. In the last few weeks, some South Korean and Japanese banks have been testing Ripple's systems for cross-border payments, according to the company.
The start-up owns 61 percent of the 100 billion XRP in existence. At Friday's record high prices, that gives Ripple about $136 billion worth of the digital currency.
