Recently unearthed insights from a 2013 discussion reveal that Zerocoin, the technological backbone of Zcash, might include a so-called surveillance entrance within its system. Zcash There is speculation about a hidden 'police backdoor' within the code, initially publicized through an article that has since been scrubbed but is accessible via the Way Back Machine's internet archive. This piece, titled 'Bitcoin Add-On Makes Your Virtual Purchases Private,' was published in March 2013 by New Scientist. In this article, commentary from Matt Greene, a researcher from Johns Hopkins who now contributes to Zcash, was central. The recovered article was brought back into the limelight by a Twitter account named 'notgrubles.' grubles “.
Zcash Troubles Abound
Zcash is a privacy cryptocurrency Zcash has been mired in several disputes since its inception. Controversial concerns such as the 'founders' tax' and the notorious 'trusted setup' have stirred debate among experts who consider these mechanisms potentially exploitable. These constructs could theoretically be leveraged to mint limitless Zcash coins without detection.
Originally, the Zerocoin initiative aimed to integrate privacy features into Bitcoin's core framework, a goal that was never realized, prompting the team to launch Zcash as a standalone project instead.
Possible Backdoor?
Although the internet may lose certain pages over time, it seldom forgets entirely. One such instance involves a deleted page concerning Zerocoin and Matt Green, an active scientist on Zcash’s team.
Zerocoin, initially slated to augment Bitcoin, eventually became independent as the cryptocurrency we recognize today as Zcash.

The concept behind such a backdoor is akin to leaving a hidden gate in software, allowing undisclosed access to systems by authorities or developers, similar to methods employed by cyber intruders.
So what did Matthew Green say in the interview with NewScientist In the interview, Matt Green expressed that neither he nor his team were inclined toward fostering criminal activities with Zerocoin. Instead, he mentioned the potential addition of features that could facilitate law enforcement tracking illicit financial flows via a proverbial backdoor.
The presence of such a surveillance entry would effectively nullify all privacy assurances associated with Zcash, implying that every transaction could potentially be exposed or leveraged in judicial proceedings.
Confirmation of a hidden backdoor, while speculative at best, would suggest that high-level analytics similar to those used on Bitcoin could be conducted across the Zcash network.
Does Zcash Have a Backdoor?
This is a challenging issue tied closely to the idea of a trusted setup, which was pivotal at Zcash’s launch when key cryptographic components were established to safeguard network obscurity.
To those unfamiliar, the trusted setup was a crucial initial step during Zcash’s launch in 2016 where root cryptographic keys were generated, essentially serving as the foundational safety net for the network’s confidentiality. Trust in the creators was paramount, as retained setup information could lead to unchecked creation of Zcash units or access to transaction secrecy.

Apart from the trusted setup, there's a slim chance that an undisclosed backdoor may exist without being discovered. Nonetheless, probabilities are against the existence of such vulnerabilities within Zcash.
The Case Against a Backdoor
Consider this situation: if an agency like the FBI exploited a backdoor in Zcash for busting unlawful actions, entering evidence into the legal arena would necessitate acknowledging how transactional data was obtained, likely triggering a public relations nightmare reducing trust and coin value sharply.
Those behind Zcash, benefiting from a founder’s reward, likely hold substantial interests in their creation. Hence, implementing a backdoor would be against their financial interest, eroding the currency’s worth and jeopardizing public reputation, potentially dissuading them from future technology ventures.
An alternate scenario might involve a covert system diligently amassing transactional information from Zcash, lying dormant until some unforeseen moment when this data can be strategically utilized.
Certainty eludes us when discussing the existence of a backdoor in Zcash. Nonetheless, the willingness of an original Zerocoin developer, now affiliated with Zcash, to consider a backdoor option adds a layer of mystery.
Simply put, there's no hard evidence proving Zcash either includes or excludes a backdoor. All available data points back to an article that’s five years old, raising some eyebrows still lacking a definitive conclusion.
