Quantum Computing

Quantum computing poses a credible long‑term threat to Bitcoin’s signature security, but timelines and risk profiles vary widely. This article translates current research into concrete mitigation steps CTOs and institutional custodians can act on now.

This technical explainer unpacks how quantum computing threatens elliptic‑curve security for BTC and why zero‑knowledge cryptography is emerging as a pragmatic, non‑consensus stopgap. It ends with a prioritized checklist custodians and protocol teams can use to assess exposure and plan mitigations.

An authoritative explainer for CTOs and security leads on the quantum-computing risk to blockchains, what post‑quantum cryptography (PQC) means, industry responses like Solana’s Project Eleven, and concrete migration steps for operators, exchanges and custodians.
