Synopsis: Quantum computing creates a threat to the security of crypto assets, as these assets are likely to be compromised due to the breaking of the encryption system. Therefore the future of digital assets will be changed.
The technology associated with quantum computing has been moving very fast, and currently, the major threat to cryptocurrencies is quantum computing technology. It is found that quantum computers have the capability to threaten the cryptographic principles that are used for the security of cryptocurrencies such as Bitcoin and Ethereum, as quantum computers can solve complex problems much faster compared to classical computers.
In this case, private keys could be derived from public keys, hence threatening the security of the funds. The importance of the threat is the fact that, if realized, the security of the assets will be compromised.
Key Stats and Market Data
- Research has indicated that only 1200-1450 logical qubits and 70-90 million operations are required to break the encryption system of cryptocurrencies.
- The breaking of the encryption system of cryptocurrencies, which can be done within 10-20 minutes using quantum computing technology.
- There are about 1.7 million Bitcoins stored in older addresses, meaning that public keys are exposed to the threat of quantum computing.
Understanding the Quantum Threat
To start with, cryptocurrencies are based on elliptic curve cryptography, which is only vulnerable to quantum computing technology, specifically Shor’s algorithm, which can generate private keys from public keys, thus breaking the security mechanism of blockchain technology. Unlike the financial system, crypto has no recovery options. The loss will be permanent if there is only one successful attack.
Another major factor that needs to be considered is that crypto has two types of attacks:
On-Spend and At-Rest. On-Spend attacks involve transactions, whereas At-Rest involves public keys. According to research, if quantum computers become more powerful, transactions will be stolen within just a matter of minutes.
Impact on Investors
Short-term traders
- Increased volatility in crypto markets due to fear-based stories.
- Negative sentiments, causing short-term price corrections.
- Liquidity risks due to trader reactions towards newly emerged risks.
Long-term Investors
- Quantum-resistant cryptography will be more prominent in crypto markets.
- More emphasis will be given to security upgrades by institutions.
- More capital will be invested in quantum-resistant blockchain technologies.
Advantages, Key Risks and Catalysts to Watch
Advantages
- Development of Post-Quantum Cryptography technologies.
- Use of Post-Quantum Cryptography in certain blockchain projects.
- More innovative security technologies will be developed.

Key Risks
- Most dormant crypto will be at risk.
- Migration from current cryptography to PQC will be a complicated process.
- Disruptions in networks during upgrades.
Catalysts to Watch
- Adoption of Post-Quantum Cryptography technologies in major blockchain networks.
- Upgrade of crypto wallets, reducing exposure risks associated with public keys.
- Regulated framework and policies around crypto security and Quantum computing advancement.
Outlook
Quantum computing is a structural problem that is a longer-team issue rather than a crisis for the crypto markets. The current systems are functioning, and the move to quantum-resistant security is becoming a pressure issue.
The technology and its adoption are areas that need to be monitored, and this is an important factor that is expected to determine the next step for the crypto markets. Being early to quantum-safe technology may give a competitive edge, and falling to adapt may make the system even riskier.
