Special thanks for Adam Gibson and Chris Belcher from JoinMarket, Ethan Heilman from TumbleBit, Dan Gershony from Breeze Wallet and Kristov Atlas from Open Bitcoin Privacy Project for tolerating my constant bugging and bothering to acquire their invaluable reviews, suggestions and feedbacks.While fungibility is an essential property of good money, Bitcoin has its limitations in this area. Numerous fungibility improvements have been proposed; however none of them have addressed the privacy issues in full. ZeroLink is first to offer protections against all the different ways a user's privacy can be breached. The scope of ZeroLink is not limited to a single transaction, it extends to transaction chains and it addresses various network layer deanonymizations, however its scope is limited to Bitcoin's first layer. Even if an off-chain anonymity solution gets widely adopted, ultimately the entrance and exit transactions will always be settled on-chain. Therefore there will always be need for on-chain privacy.
