Recently, Casa's chief technology officer, Jameson Lopp, in a podcast, talked about the platform's privacy protection. Lopp said that the Casa application can provide different levels of KYC and AML based on the user's choice of shared personal data. In addition, the security expert also mentioned that in most cases, mobile devices are more secure than desktops for Bitcoin protection. He believes this view is based on malicious browser extensions and a larger attack surface. Lopp's discussion of this topic adds that Ethereum has an inherent (security) problem because they do not have local multi-signature capabilities.
