‘Expert Warns Public Blockchains Have a ‘Critical Weakness’ That Could Lead to Crypto’s Downfall Without Privacy’

The primary challenge facing cryptocurrency is not regulation or volatility, but a more fundamental issue: the absence of privacy, according to Petro Golovko, a finance and gold expert with over 40 years of experience in the industry.

Golovko, who serves as the trust protector at British Gold Trust, asserts that public blockchains render cryptocurrency impractical for everyday users and unfeasible for institutions. He claims they reveal salaries, business transactions, and entire financial statements to the public.

Notably, British Gold Trust utilizes a private blockchain to manage billions in tokenized assets, which are backed by physical gold. Golovko explained during a phone conversation that no cash is exchanged within the underlying Goldtech Ecosystem; only gold is involved.

Golovko, also a researcher in decentralized AI and quantum finance, emphasized that the Trust’s blockchain is private, meaning that, unlike the Bitcoin blockchain, Goldtech’s is not accessible to the public.

He perceives cryptocurrency as a flawed concept pursuing non-existent problems, contrary to the notion of it being the future of money, as he highlighted in a recent LinkedIn post.

In this interview with Cryptonews, Golovko addresses the industry’s major assumptions and articulates why privacy will not rescue cryptocurrency, but rather reveal its limitations and vulnerabilities.

‘Crypto Will Never Scale Beyond a Niche’

Cryptonews: You’ve stated that “crypto will fail without privacy.” Can you elaborate on that?

Petro Golovko: No monetary system can endure if every transaction is permanently public. Individuals do not wish for their salaries, savings, or business transactions to be exposed. This is not innovation; it is surveillance masquerading as transparency. Without privacy, cryptocurrency will never expand beyond a niche.

CN: If privacy were incorporated, wouldn’t that merely reinforce the same corporate and banking power structures that cryptocurrency aimed to disrupt?

PG: No. Privacy is not about reinforcing authority; it is about facilitating genuine participation. In its absence, only speculators can tolerate the exposure. With privacy, it becomes possible to create alternatives to traditional banking systems. The issue lies not with privacy itself, but with whether the trust architecture is independent of fiat obligations.

CN: Many within the crypto sector argue that transparency is a virtue. You view it as a critical flaw for widespread adoption. Why do you believe they are mistaken?

PG: Transparency is beneficial for auditing purposes, not for daily life. A system where your employer, competitors, or even strangers can view your balance is not transparent; it is unlivable. Genuine trust arises from selective visibility: private by default, verifiable when necessary.

CN: Your post indicates that 95% of individuals do not want their financial information, such as salaries, publicly displayed. What are the dangers of having salary information visible on-chain, and would you argue that crypto adoption has already reached its peak because of this?

PG: Public salary information leads to competitive exposure, HR liabilities, and even personal security threats. No reputable company will implement a payroll system that discloses compensation on a global scale. This is why adoption has stagnated — the technology does not align with human realities.

CN: How significant is the risk for businesses to have payroll or trade data exposed on a blockchain?

PG: It is existential. Trade secrecy is fundamental to maintaining a competitive edge. If your supply chain or treasury activities are visible, you have already lost. No board of directors would approve such exposure.

CN: If institutions cannot transact privately on-chain, does that imply that cryptocurrency will remain a niche tool for traders and speculators?

PG: Precisely. Public ledgers are suitable for speculation, allowing individuals to compare portfolios on Twitter. However, they cannot support serious commerce. Without privacy, cryptocurrency remains a casino rather than a monetary system.

The Bubble Will Pop: ‘Crypto Is For Hobbyists’

CN: What are your thoughts on companies like BlackRock and Fidelity, which have made significant investments in Bitcoin and Ethereum ETFs?

PG: That is not adoption; it is packaging. ETFs are fiat wrappers around speculative assets. Institutions are capitalizing on volatility, not creating monetary systems. It represents financial engineering, not systemic transformation.

CN: Do you believe regulators actually prefer the current arrangement because public ledgers facilitate surveillance?

PG: Certainly. Regulators appreciate the visibility. It simplifies monitoring, but it also ensures that cryptocurrency will never evolve into mainstream money. A system designed for surveillance will not attract widespread adoption.

CN: Can you draw a parallel between the early internet’s lack of encryption and today’s blockchain transparency? What lessons from the dot-com boom is the crypto sector failing to grasp?

PG: In the 1990s, people were reluctant to enter credit card numbers into a browser due to the absence of encryption. Then SSL was introduced, Amazon expanded, and e-commerce grew into a $6 trillion industry. Blockchain is trapped in the pre-SSL phase. Until it addresses privacy, it will not scale. This is the lesson the industry refuses to acknowledge.

CN: Would you argue that the concept of a public ledger for money was fundamentally flawed from the outset?

PG: Yes. It functions for hobbyists and traders, but not for societies. Money necessitates both permanence and discretion. A public ledger by default is a design flaw — it conflates auditability with exposure.

Additional note:

PG: The narrative of cryptocurrency is not solely about technology. It revolves around the architecture of trust. A system that requires total exposure of its users cannot maintain trust. Therefore, privacy is not a luxury — it is essential.
