TRON’s Bold Move: Are Bitcoin and Ethereum Falling Behind in Quantum Security?

“Quantum Security Shouldn’t Be a Debate”: Justin Sun Targets <a href="https://investment-policy.com/btc-usd/">Bitcoin</a> & <a href="https://minority-mindset.com/eth-usd/">Ethereum</a>

Key Highlights

  • Justin Sun announced TRON’s post-quantum upgrade, saying the network aims to lead rather than debate quantum security.
  • The initiative targets NIST-standardized cryptographic signatures, positioning TRON ahead of Bitcoin and Ethereum’s slower approaches.
  • TRON is leveraging its stablecoin dominance to push a “quantum-safe by default” narrative in the evolving crypto race.

Earlier today, the founder of TRON announced on X that the network is beginning an upgrade to protect against future quantum computing threats. This makes TRON the first major public blockchain to use new, NIST-approved encryption methods on its live network. He also used the announcement to criticize two of its biggest competitors.

While Bitcoin discusses protecting potentially vulnerable coins and Ethereum creates research groups, TRON is actively developing solutions. Sun emphasizes that quantum security isn’t something to argue about – it should be a standard part of the system. TRON aims to protect its users from losing their funds due to future quantum computing threats.

A technical roadmap, he added, is “coming soon.”

A direct shot at Bitcoin and Ethereum

TRON’s recent actions aren’t a coincidence. Throughout most of 2026, the cryptocurrency world has been intensely discussing how to prepare for the potential dangers of quantum computing, but TRON hadn’t participated in those conversations – until now.

The discussion around Bitcoin is becoming more concerning. New analysis of the Bitcoin network shows that about 6.98 million BTC (around $440 billion) is held in accounts that could be vulnerable to future quantum computers. This includes an estimated 1.1 million BTC believed to belong to Bitcoin’s creator, Satoshi Nakamoto.

A disagreement has emerged among Bitcoin developers and community members. Some want to address potentially compromised coins by proposing a ‘soft fork’ – a change to the rules that would essentially lock or destroy them, like with BIP-360. Others strongly believe that making any changes to the Bitcoin blockchain would violate its core principle of being unchangeable.

Recently, both Lightning Labs’ CTO Olaoluwa Osuntokun and Blockstream’s Adam Back have pointed out that even the proposed fixes carry a significant risk: users could lose access to their own money.

While Ethereum appears to have a clearer plan for dealing with quantum computing threats, the process will still take time. In January 2026, the Ethereum Foundation created a specific team to research post-quantum cryptography. Then, in February, Vitalik Buterin released a four-year plan – known as the “Strawmap” – to shift away from current signature methods (ECDSA and BLS) to more secure, hash-based options, using upgrades like Glamsterdam and Hegotá.

The plan is quite ambitious, but most discussions about Ethereum and this topic emphasize a step-by-step approach. Achieving full protection against quantum computers is seen as a long-term project, likely taking until around 2030.

That gap between debate and deployment is exactly the wedge Sun is now driving into.

What TRON is actually promising

Sun admits the announcement doesn’t have many details yet, but the way he worded it suggests the information is still significant.

TRON is demonstrating its commitment to future-proof security by planning to use new encryption methods approved by the U.S. National Institute of Standards and Technology. These methods are designed to protect against the potential threats of quantum computers.

For blockchain applications, the most promising option is SLH-DSA, also called SPHINCS+. This signature scheme, standardized as FIPS 205 in August 2024, is based on hashing. Other options selected by NIST include ML-DSA (CRYSTALS-Dilithium) and FN-DSA (Falcon).

These systems are built to protect against future attacks from powerful quantum computers using Shor’s algorithm. This algorithm could potentially break the security of cryptocurrencies like Bitcoin and Ethereum by revealing the private keys behind public ones. However, this enhanced security comes at the cost of increased size and expense.

Signatures like SLH-DSA are much larger – potentially 8 kilobytes or more – than the approximately 64-byte signatures currently used by Bitcoin and Ethereum. This size difference is why developers have been carefully exploring ways to compress, combine, and verify these larger signatures for years before considering any changes to the main networks.

Sun’s pitch is that TRON will simply ship it, and ship it first.

Why is the timing sharp

This news comes at a time when the potential dangers of quantum computing are becoming very real. Just recently, Google researchers showed that a powerful enough quantum computer could, theoretically, crack the security behind Bitcoin in less than nine minutes – and this could happen as soon as 2029.

A researcher at StarkWare has proposed an emergency plan, called Quantum Safe Bitcoin, to protect transactions, but it could cost up to $200 per transaction. This has sparked discussions among Bitcoin developers about potentially making major changes to the system, known as a hard fork. Just a year ago, such ideas seemed unlikely.

Considering the current situation, Justin Sun’s message of “while they argue, we build” feels less like typical advertising and more like a strategic effort to position TRON as the leader in post-quantum technology before Bitcoin or Ethereum can launch their solutions. This approach is very characteristic of Sun, a founder known for prioritizing publicity and being first to market, even before the technology is fully ready.

The stakes for TRON

TRON has a strong argument for taking a firm stance on this issue. The network has become the main pathway for stablecoin transfers in many parts of Asia, Africa, and Latin America, and it now handles billions of dollars in daily USDT transactions. If TRON were successfully attacked by a quantum computer, it wouldn’t just impact TRX owners – it could cause problems for the entire global stablecoin system. This gives Justin Sun a clear reason, and a legitimate basis, to be so vocal about the threat.

This also gives TRON a significant advantage. If TRON can successfully implement secure, future-proof digital signatures based on NIST standards on its main network while Ethereum is still working through various updates and Bitcoin debates the possibility of freezing old coins, TRON can effectively market itself as being “quantum-safe by default”—a claim very few competitors can make.

Naturally, some people are questioning the announcement, given Sun’s past habit of building hype before delivering actual results. The crypto community has learned to be cautious and wait to see the working code. When the technical details are released, they’ll need to clearly explain several key things: which post-quantum cryptography standard TRON will use, how current validators and wallet users will upgrade, what will happen to existing TRX, USDD, and TRC-20 tokens, and how the network will manage the increased data size from the new cryptography without increasing transaction costs or block sizes.

Right now, Sun has successfully done what he’s known for: he’s brought TRON into the spotlight and challenged Bitcoin and Ethereum to compete.

He announced that the long-awaited plan will be released shortly. The cryptocurrency world will be closely observing to see if the actual results live up to the hype.
