Robinhood CEO Vlad Tenev argues that tokenizing stocks on blockchain is the key solution to avoid trading halts like those during the 2021 GameStop frenzy.

The industry and regulators are increasingly embracing tokenization, with major players like NYSE and Nasdaq developing platforms and regulatory frameworks to support this shift.
