According to Howard Wu, Ethereum's account model fundamentally prevents effective implementation of privacy features. Wu asserts that privacy cannot be retrofitted onto Ethereum due to its original design, making it difficult for traders seeking confidential transactions to rely on ETH-based privacy solutions. This analysis suggests that market participants should be cautious about expecting true privacy on Ethereum (ETH), as its technical structure imposes inherent limitations. Source: @1HowardWu.

According to Vitalik Buterin on Twitter, the user experience (UX) of zk-SNARKs remains a significant hurdle for broad adoption in the Ethereum ecosystem, despite notable improvements in platforms like 0xPrivacyPools. Buterin commented that 0xPrivacyPools offers a user interface comparable to Safe, which is widely recognized for its accessibility, but he emphasized that development experience (devex) is still far more complex for zero-knowledge (ZK) applications than for traditional smart contract platforms. This distinction is meaningful for crypto traders and DeFi users, as enhanced privacy protocols like 0xPrivacyPools can facilitate more secure and private transactions while their usability continues to improve. However, the complexity on the developer side may slow down the pace of new ZK-based privacy features reaching the market, potentially affecting the growth trajectory of privacy-focused Ethereum applications and the broader adoption of privacy coins.
