BLOK seeks total return from companies developing or utilizing blockchain technologies. Blockchain, which is the technology that drives Bitcoin, is a distributed, peer-to-peer ledger that facilitates recording transactions and tracking assets in a business environment. The fund further classifies eligible companies into two groups: core, with 70% weight, are firms that derive direct revenue from developing or profitably deploying data sharing technologies, and secondary, having the remaining 30% of the portfolio, are those that have partnered with or invested in such firms. The funds active manager may select companies from any country or industry. Prior to October 13, 2025, BLOK was named Transformational Data Sharing ETF.
