Sand Hill Road has gone crypto-crazy, making it the best time ever to be a cryptocurrency or blockchain-based startup. Six such companies drew our attention enough to make it into this year’s The Information 50 list of promising startups. They range from an environmentally friendly cryptocurrency to the “picks and shovels” businesses enabling others to develop crypto products—such as nonfungible token marketplaces—or make sure they’re legally compliant.

In today’s episode, executive editor Amir Efrati speaks with crypto reporter Hannah Miller about the startups that made the cut. Then Hannah talks to the co-founder of one of them—Audius, a blockchain-based music-streaming service trying to give musicians a bigger cut of streaming revenue. Its crypto tokens are already worth $1 billion collectively. Check out the final episode of our five-part series.
