This is just a random news I get but people are really talking about it.
I have just read about it not long ago but I have also read somewhere before that by 2030, it is possible that ECDSA becomes vulnerable to quantum computing. This is 2025 which means 2030 is just 5 years away from now.
What do you think about this disturbing news, I have been read more than 5 news about this and I saw another one today. What are bitcoin developers doing about it?
If you need the source that I get today's news from, I can post it which has the the title that I have as the title on this thread.
What’s the Actual Quantum Threat?
ECDSA Vulnerability:
ECDSA security relies on the hardness of the elliptic curve discrete logarithm problem. Large-scale, fault-tolerant quantum computers running Shor’s algorithm could theoretically
solve this problem efficiently, breaking ECDSA and exposing private keys.Timeline Uncertainty:
While some estimates suggest that powerful quantum computers capable of breaking ECDSA could emerge by 2030 or later, there is significant uncertainty about when exactly such quantum hardware will be built and become practically usable against Bitcoin’s 256-bit curve.
What Are Bitcoin Developers Doing?
Active Research on Post-Quantum Cryptography (PQC):
The Bitcoin community and cryptographers are investigating quantum-resistant signature schemes like Lamport signatures, hash-based signatures (e.g., XMSS), lattice-based cryptography, and others.
Layered and Gradual Transition:
Transitioning Bitcoin to quantum-safe cryptography is non-trivial. It would require protocol changes and careful migration strategies to avoid compromising security during the upgrade.
Focus on Wallet Hygiene:
Since reuse of public keys is a major risk if a quantum adversary can break ECDSA, best practices like avoiding address reuse and using new addresses for each transaction reduce exposure.
Monitoring Quantum Computing Progress:
The ecosystem closely follows advances in quantum hardware, error correction, and algorithms to adjust timelines and plans accordingly.
What Can Users Do Today?
Use wallets and addresses that avoid reusing public keys (HD wallets help here).
Stay informed about developments in quantum resistance in Bitcoin protocols.
Support open discussions and development efforts on quantum-resistant upgrades.
