Solana Policy Institute, a newly created crypto advocacy group, has appointed Rachel Green Horn as its chief marketing officer. Green Horn, formerly the chief marketing and communications officer at Filecoin Foundation, began her role recently. The institute, led by Miller Whitehouse-Levine and soon to be joined by president Kristin Smith, aims to influence crypto-related legislation and regulatory bodies such as the SEC's Crypto Task Force and the Commodity Futures Trading Commission. The group focuses on stablecoin and market structure bills amid ongoing regulatory developments in Washington. Green Horn brings extensive experience from both the crypto sector and tech trade associations, enhancing the institute's advocacy efforts. The institute's work occurs in a complex environment where political figures like former President Donald Trump have shown support for crypto, impacting legislative dynamics.
