Bitcoin Quantum Threat Takes Center Stage at Ethereum Conference
The main topic of discussion during the latest conference dedicated to the use of Ether was Bitcoin’s susceptibility to quantum computing. On this note, what was otherwise a minor technical tangent topic was the most popular topic of the conference. There, they came face to face with what emerging quantum technology could do to not only bitcoin but the blockchain community at large as well as Ethereum.
Here’s what it means, why it’s important, and whether or not the average crypto holder should be worried.
Why Quantum Computing Is Suddenly a Big Deal
Quantum computing has forever been viewed as a futuristic leap in technology. Qubits allow quantum machines to perform certain calculations at exponential speeds compared to classical ones. Leading technological companies such as IBM and Google are undertaking intensive studies on quantum processors.
What does this have to do with Bitcoin then?
Bitcoin uses cryptographic algorithms, the elliptic curve cryptography (ECC) to secure wallets and verify transactions. This is theoretically possible through the Quantum computer that has a capacity to decrypt the cryptographic shield and unmask private keys hence exposing any corresponding funds.
It may not be the case now but the idea of this conversation is no more a science fiction. The idea may not be that now but the idea of this conversation is no more a science fiction.
Why This Topic Emerged at an Ethereum Event
It might be strange that the security risks of Bitcoin are to be presented at an Ethereum conference. But the blockchain community is related.
Developers of the Ethereum blockchain understand that if a flagship Cryptocurrency experiences a loss of trust, the mistrust is spread throughout the markets. Accordingly, the developers deploying smart contracts on Ethereum understand that when there is trust in one leading cryptocurrency there is trust in the rest, and if there was a successful attack on Bitcoin using quantum technologies then decentralized finance would be undermined.
More important, the Ethereum community has proven proactive to the extent of launching researches on post-quantum cryptography.
The discussions during the event stressed;
Importance of quantum-resistant signature schemes. Wallets already in practice, and the migration. Significance of quantum-resistant signature schemes.
Bottom line: this isn’t a Bitcoin vs Ethereum fight – it’s about staying alive in a world where tech doesn’t wait for anyone.
Is Bitcoin Really at Risk Today?
The short answer to this question is that people do not become racist immediately.
There is consensus among most experts that quantum computers capable of breaking Bitcoin’s encryption at scale are not in existence yet (ibid). The existing quantum machines operate under low power and fluctuating conditions.
On the other hand, the crypto industry long term thinking. Because blockchain transactions are permanent and public, attackers could harvest public keys today with the hope of breaking them in the future once quantum computers are powerful enough.
That “harvest now, decrypt later” is one of the reasons why developers have pushed for solutions that are proactive rather than reactively panic-induced.
What Are the Possible Solutions?
Some of the ways forward include;
1. Post-Quantum Cryptography
New cryptographic algorithms that explicitly resist quantum attacks are being formulated by researchers. Eventually, they might replace signature schemes in Bitcoins or Ethereum.
2. Protocol Upgrades
An upgrade from the current bitcoin’s network may result in quantum resistant addresses. Upgrading bitcoins is, therefore, not impossible but requires massive consensus.
3. User-Level Measures
The experts recommend that the users never use address re-use. The theoretical quantum threats are currently considered impotent on funds stored in addresses that have never exposed public keys.
What This Means for Crypto Investors
Everyday holders do not have to take part in panic selling. Everyday holders do not have to indulge into panic selling and the quantum threat being long-term view; there is no immediate need of panic selling among common holders.
On the other hand, this discussion should be reminder;
The rate of change in technology is in an upward slope. Security models also have to change accordingly.
Blockchain is not a set it and forget solution and is continually improved on and improved.
The fact this conversation takes place now before any real quantum breakthrough further points to a crypto ecosystem maturity.
The Bigger Picture: Innovation Meets Responsibility
The tone was perhaps one of the most optimistic aspects of the conference discussion. Rather than considering the dismissal of the threat from quantum, developers regarded it as a serious but manageable engineering challenge.
Bitcoin and Ethereum communities are both composed of researchers who are cryptography experts. The quantum resistance is only a step of the blockchain evolution.
This means that just like the internet was eventually able to adopt security protocols, so too will blockchain networks.
