Cardano Founder Warns on Quantum Encryption Risks
Charles Hoskinson, founder of Cardano, has raised concerns about the future impact of quantum-resistant encryption on blockchain performance.
While NIST is expected to standardize post-quantum encryption methods, Hoskinson warns that without hardware acceleration, these systems could bring heavy computational costs and larger data sizes — potentially reducing blockchain throughput by nearly 10x 📉
🧠 Why it matters:
Quantum-safe cryptography is necessary, but poor implementation could slow networks significantly, creating new scalability challenges.
🔬 Hoskinson also pointed to DARPA’s quantum benchmarking program, which aims to assess whether practical quantum computing could become viable by 2033 — a key timeline for blockchain security planning.
📌 Bottom line:
Quantum resistance is essential, but performance trade-offs can’t be ignored. The race is on to secure blockchains without sacrificing scalability.
