Bitcoin Evangelist Calls to Boycott Edward Snowden’s Book

Bitcoin evangelist Samson Mow is refusing to overcome his hatred for American whistleblower Edward Snowden.

The Blockstream CTO ‘evidently’ asked his social media followers to boycott Snowden’s new book, titled Permanent Records,’ reminding the former CIA employee’s love for bitcoin’s rival, Zcash (ZEC). Mow said Snowden recommended to buy ZEC for people looking for financial privacy when a bug in the cryptocurrency later uncovered the users’ so-called private transactions.

Zcash Controversy

Mow was referring to a research paper published by four academics in May 2018. The study showed that specific kind of Zcash transactions exposes users’ so-called privacy. In retrospective, Zcash offers two types of addresses: “t-addresses,” which are transparent, meaning their balances are visible on a public blockchain, and “z-addresses,” which are invisible to onlookers.

Researchers George Kappos, Haaroon Yousaf, Mary Maller, and Sarah Meiklejohn found that transactions between the same kind of addresses did not create troubles. But the scenario flipped when users transacted between different types of wallets. Onlookers were able to look behind z-addresses which revealed users’ involved with the transactions.

Snowden, who became the flagbearer of user privacy rights and free speech after he leaked highly classified information from the National Security Agency (NSA), favored Zcash. In his tweet issued in late 2017, the computer security expert had called the cryptocurrency “the most interesting alternative to Bitcoin,” a thought that did not sit well with Mow, a staunch bitcoin evangelist.
