reusable address privacy problems & fuzzy bait limitations (Re: Stealth Addresses)



Summary:

In an email exchange between Drak and Jeremy Spilman on January 16, 2014, they discussed a proposal for a "reusable address" but struggled to find suitable terminology as all addresses are technically reusable. They eventually settled on the term "public address" for common usage. However, concerns were raised about the effectiveness of this proposal in terms of privacy, with one user suggesting that it may actually be worse than the existing SPV bloom mechanism. This led to a discussion about potential solutions, including Peter's stealthify payment variant and Greg Maxwell's improved prefix/bloom bait. While these options offered incremental improvements, they still posed significant risks to privacy and could be subject to statistical network flow analysis. Despite these challenges, some users continued to promote the idea of reusable addresses for full-node recipient scenarios.
