State of the transaction privacy work in Bitcoin

The discussion emphasizes the commonality of transactions involving repeat payments where the amount is predetermined. However, it calls for evidence or data sources that substantiate this claim, highlighting a gap in documentation or research that underpins such assertions. Moreover, it raises concerns about privacy issues associated with current transaction practices, particularly criticizing the prevalent use of Electrum-based light wallets. These wallets, according to the argument, contribute significantly to address reuse, exposing users to potential chain surveillance risks.

Further, the critique extends to the effectiveness of generating new addresses as a privacy measure. It suggests that this strategy offers minimal protection unless the user operates a wallet that supports BIP157/158 or functions as a full node. This point underscores a significant limitation in the typical approaches employed by many users to enhance transaction privacy and security. The concern here is not just about the reuse of addresses but also about the overall efficacy of commonly recommended privacy practices within digital transactions.
