Summary
The quantum threat timeline for cryptocurrencies may arrive sooner than expected; Google and other entities estimate practical attack capability around 2029. Most blockchains rely on elliptic curve cryptography, which would then be breakable, potentially exposing an estimated 35–50% of Bitcoin's ci…
Key points
- Long-term holders and infrastructure developers must recognize the urgency of a cryptographic migration and start planning upgrades and asset protection strategies.
- Quantum computing will fundamentally challenge blockchain security assumptions, affecting the long-term viability of trillions in digital assets.
- Retail holders should monitor wallet and protocol quantum-resistance upgrades; developers should invest in post-quantum signature research; institutions may reassess custody solutions.
