privacy policy ."Bitcoin primarily uses signatures, not encryption. This is like saying, we decided to run our rocket on water, since NASA uses Hydrogen and Oxygen," Ian Miers, Assistant Professor of Computer Science at the University of Maryland, said on X. Encryption refers to the process of scrambling data so that only authorised parties with the correct keys can unscramble and read it. However, transactions executed on the Bitcoin blockchain aren't encrypted but are signed. In fact, all data shared between Bitcoin nodes is unencrypted, allowing total strangers to interact with the network. "Needless to say "Bitcoin style" and "Rust" are not descriptions of an encryption scheme, nor are they strong indicators of security for a messaging app. Also, unless encrypted DMs are only in app, odds are they aren't just in Rust," Miers said. Bitcoin, the leading cryptocurrency by market value, traded flat near $105,000, having dropped over 3% last week, according to CoinDesk data. Other key features of the new offering include end-to-end encryption, disappearing messages, and the ability to send any type of file, including audio and video files, without a phone number across all platforms.
