The U.S. Securities and Exchange Commission (SEC) is developing a plan to allow stocks to be traded on blockchains like cryptocurrencies, but the plan faces strong opposition from traditional financial firms such as Citadel Securities, according to people familiar with the matter. SEC staff are discussing the plan with industry representatives, a top priority for the Trump administration's push for cryptocurrency-friendly regulation. If the plan is approved, investors will be able to purchase tokens. (The Information)
