According to @1HowardWu, the term 'ZK' (zero-knowledge) is increasingly used in the crypto market to refer to a wide range of projects, but most of these implementations focus on scaling rather than true privacy. Traders should recognize that only a subset of ZK projects deliver confidentiality features, which can directly impact the value proposition, regulatory risk, and long-term adoption of related tokens. With many ZK-based solutions being marketed primarily for scalability, it is critical for crypto traders to distinguish projects offering real privacy benefits from those that do not (source: @1HowardWu on Twitter, May 9, 2025). This distinction affects market perception, token utility, and investment potential within the zero-knowledge ecosystem.
