- Quantum risks to Bitcoin are rising faster than markets expect.
- About one-third of the Bitcoin supply shows structural exposure today.
- Large institutions now list quantum computing as a material risk.
Long-term threats to Bitcoin security now move closer to reality. A new report warns that quantum computing advances outpace market expectations. David Duong of Coinbase leads the warning. He says Bitcoin enters uncharted territory.
He says that already a third of all Bitcoins show vulnerability. The problem does not lie only in the future. It also exists in the present. Quantum computing is still in its early stages of development, but it continues to accelerate. These computers are based on “quantum mechanics.
They have different approaches to problem-solving.
Conventional computers will never be able to provide the same level of security. If the trend persists, the underlying security of Bitcoin itself might be at risk. One such aspect of Bitcoin is its cryptography. Its assumptions include constraints on computing capability. Quantum computers defy this assumption. With increased capability, safety margins will continue to narrow. Investors are now realizing this fact.
Quantum Computers Threaten Individual Wallets
One area that is highlighted as the biggest flaw by the report is the wallet design. Public keys for many wallets are visible on the chain. This is the case for approximately a third of the total units that make up the Bitcoin market. Now that the public key has been made visible, it will always be that way.
Quantum computers could use such information. A private key could be calculated using a public key. A hacker could then transfer money unauthorized. Such an attack does not require control over the entire network. The targeted area is an address. Optimists and pessimists debate timelines.
But the direction is not debated. The power of quantum is always on the rise. The defense upgrade is slow. This has led major companies to start echoing the same concern. BlackRock has expressed concerns over “quantum risk” in its government filings. This signals a shift in the perception of institutional investors. They no longer underestimate the threat.
Quantum Computing Challenges Bitcoin Safety
Bitcoin’s security relies on two factors. The first is related to ownership. The other is related to mining. Each is under attack. The first factor relies on digital signatures. The digital signature is a way to prove ownership of bitcoins. However, quantum computers can break a digital signature. That makes it easy for a thief to steal bitcoins from an open wallet.
The second pillar relates to mining. This involves the use of hashing to secure the network. Quantum computers could perform mining faster. This could create a distorted incentive structure. This could lead to control by bigger quantum computers. This control could undermine decentralization.
This may also impact trust in network impartiality. Even without attacks, there may be changes in economics. Current research focuses on protection. Upgrades need consensus. Bitcoin changes progress slowly.
Time is of the essence. The danger may not come tomorrow. But preparation needs to begin early. Bitcoin’s security is today challenged over a period of several decades. The market today may disregard the danger. But history tells us that technological changes come unexpectedly. Bitcoin today is at a junction where there is a need for research rigor and planning.
