# Bitcoin BIP-361 Draft Puts Quantum Security Back On The Agenda Bitcoin developers propose a roadmap to prepare for potential quantum computing threats. - **Source:** [NewsBTC](https://brifing.si/source/1757e8d5-352f-4479-994f-79c6e6161b17) - **Published:** 2026-07-20 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/1b0f813c-8448-49d9-8acd-bd07aced9d29 ## Bitcoin Prepares for Quantum Threats Bitcoin developers have released BIP-361, a draft proposal outlining a transition from legacy cryptographic signatures to quantum-resistant alternatives. Given Bitcoin's decentralized nature, such changes require extensive planning and consensus. The proposal aims to future-proof the network against emerging risks. ## Why Act Now? Quantum computers aren't an immediate threat, but preparation is crucial. Bitcoin's upgrade process can take years, making early discussion essential. BIP-361 emphasizes proactive measures to avoid future crises, highlighting the importance of community engagement in the planning phase. ## Challenges and Trade-offs Cryptographic migration in Bitcoin is complex due to its decentralized ecosystem. Users, exchanges, wallet providers, and miners must align. Issues like lost coins and old addresses add layers of difficulty. BIP-361 seeks to balance security upgrades with practical usability. ## Phased Transition Plan The draft proposes a gradual sunset for legacy signatures, avoiding abrupt changes. Clear milestones will guide infrastructure providers and users through the transition. This could become one of Bitcoin's most sensitive upgrades, requiring careful coordination across the ecosystem. ## Bitcoin's Deliberate Pace Is a Feature Bitcoin's slow protocol changes ensure stability but demand early preparation for critical issues like quantum migration. BIP-361 provides a structured starting point for community debate, underscoring the need for foresight in maintaining the network's long-term security. ## Market Implications BIP-361 isn't a short-term price catalyst but a signal of long-term preparedness. The draft is far from activation and may evolve significantly. Such forward-thinking proposals reinforce Bitcoin's resilience and commitment to safeguarding its core principles against future threats. ## Sources covering this story - https://www.newsbtc.com/news/bitcoin-bip-361-draft-quantum-security/ — --- _Summary written by Brifing from the original reporting.
