FC Barcelona is under scrutiny following its $22 million sponsorship deal with crypto company Zero-Knowledge Proof (ZKP). The three-year agreement, which designates ZKP as the club's official crypto protocol partner, has been labeled as financially "desperate" by former board member Xavier Vilajoana. Concerns have been raised about ZKP's background, including its registration in Samoa, a tax haven, and its limited online presence. ZKP, a relatively unknown blockchain firm, launched its social media and white paper in early November, with minimal online following. The company's website lacks transparency regarding its ownership and financial structure, and it is currently conducting an initial coin offering (ICO). FC Barcelona has clarified that the club is not involved with ZKP's tokens, emphasizing that token issuance was not part of the sponsorship discussions.
