Sure, the wild swings in the price of Bitcoin and other cryptocurrencies dominate the daily news. But beneath the headlines, the nine blockchain startups on the ForbesFintech 50 list for 2018are building infrastructure—to support both public cryptocurrency markets and initiatives that could transform how current financial transactions are executed and recorded. Five of the nine are first-timers on the list. Newcomer Chainalysis, with just $1.6 million in capital invested, already counts the IRS, FBI and Europol as users of its tools, which allow specific crypto transactions to be traced. Meanwhile, first-time list member Symbiont is working with both incorporation capital Delaware and mutual fund behemoth Vanguard, on blockchain initiatives. Notably, founders of three of our picks—The Bitfury Group, Coinbase and Ripple—also earned spots on Forbes' new list ofThe Richest People In Crytpocurrency.
