Coinbase published a report on the risks of quantum computing for blockchains. It specifically highlights Algorand and Aptos as networks that are already moving toward protection against future threats. At the same time, analysts emphasize that the threat itself remains theoretical for now and does not pose an immediate danger.
The main conclusion of the report is straightforward. Quantum computers are not yet able to break blockchain cryptography, but preparations need to start now.
The Quantum Threat Exists, but Not Today
According to researchers, sufficiently powerful quantum machines will appear sooner or later. Such systems could potentially break the cryptographic algorithms that secure wallets and transactions.
However, current technologies do not reach this level. We are talking about a horizon of years or even a decade, not an immediate risk for the market.
Algorand Is Already Testing Protection
Algorand is among the first networks to begin implementing quantum-resistant solutions. The report notes that the network already provides tools for creating accounts with enhanced protection without changing the base protocol.
Moreover, one such transaction has already been conducted on the mainnet. This is an important signal for the market: protection is moving from theory to a practical stage.
Aptos Bets on Architecture Flexibility
Aptos has chosen a different approach. In this network, the user’s key is stored separately and can be updated without transferring funds to a new address.
This simplifies the transition to more secure algorithms. The user only needs to change the signature key without touching the account or assets. This approach reduces friction when updating the system. For the mass market, this could be a critically important factor.
Proof-of-Stake Networks Under Pressure
The report pays special attention to proof-of-stake networks. According to Coinbase, such blockchains may be more vulnerable due to the signature schemes they use.
This list includes major networks, including Ethereum and Solana. This does not mean an immediate risk, but it highlights the need to update cryptography in the future.
Major Networks Are Already Preparing Solutions
At the same time, leading projects have an action plan. Solana is already testing new signature schemes, and Ethereum is preparing updates aimed at transitioning to quantum-resistant algorithms.
This reduces systemic risk. The market understands the problem and is gradually building its solution at the protocol level.
The Issue Is Not the Threat, but Preparation
The most important conclusion of the report is not about risk, but about timing. The quantum threat does not pressure the market today, but it cannot be ignored.
Blockchains are long-term infrastructure. Any changes at the cryptography level require time, testing, and coordination.
What This Means for the Market
For investors and industry participants, this is a signal to watch, not to panic. Quantum computing does not change the current valuation of assets, but it is becoming a factor in long-term development.
Networks that start adapting earlier will gain an advantage. Others will be forced to catch up under already established security standards.
What’s Next?
In the coming years, the market will be watching two things. First, the speed of quantum technology development. Second, the readiness of blockchains to adapt to new requirements.
For now, the situation looks manageable. But as soon as technological progress accelerates, the issue of quantum protection will become not theoretical, but practical.
