    Key Points

    • StarkWare researcher developed quantum-resistant Bitcoin transactions compatible with current protocol
    • Hash-based proofs replace conventional digital signatures for enhanced security
    • Transaction costs range from $75 to $200 in GPU computing resources
    • System functions as emergency backup measure rather than permanent solution
    • Established long-term proposals like BIP-360 face extended implementation timelines

    A researcher from StarkWare has unveiled a framework enabling Bitcoin transactions to withstand quantum computer threats while operating within the network’s current infrastructure and avoiding any protocol modifications.

    JUST IN: Bitcoin developer Avihu Levy introduces "Quantum-Safe Bitcoin Transactions Without Softforks" 👀 pic.twitter.com/enghEoOq10

    — Bitcoin Magazine (@BitcoinMagazine) April 9, 2026

    Avihu Levy, chief product officer at StarkWare, authored the Quantum Safe Bitcoin (QSB) proposal, which emerged this week and quickly captured widespread interest throughout the Bitcoin development community.

    The methodology substitutes standard digital signature mechanisms with a hash-based proof architecture. Conventional Bitcoin signatures depend on elliptic curve cryptography, which sufficiently advanced quantum computers could potentially compromise.

    Hash-based proofs operate through an alternative mechanism. These proofs generate distinct mathematical fingerprints of information that remain extraordinarily resistant to reversal or falsification, even when facing quantum computers executing sophisticated algorithms such as Shor’s algorithm.

    The framework demands no soft fork, no consensus from miners, and no activation schedule. This characteristic distinguishes it from BIP-360, the current quantum-resistance initiative introduced to Bitcoin’s improvement proposal repository in February yet lacking a definitive deployment schedule.

    Significant Cost Considerations

    The primary limitation involves expense. Creating a single QSB transaction demands processing billions of potential inputs, a computational task Levy calculates at $75 to $200 when utilizing conventional cloud GPU infrastructure.

    Standard Bitcoin transactions currently average approximately 33 cents in fees.

    These transactions fall outside standard parameters. They cannot propagate through Bitcoin’s regular network infrastructure like typical payments and require direct submission to miners prepared to include them in blocks.

    QSB demonstrates incompatibility with the Lightning Network, Bitcoin’s accelerated and economical payment infrastructure. This constraint confines practical application to substantial, high-value transfers where elevated costs remain justifiable.

    StarkWare CEO Eli Ben-Sasson described the proposal as “huge,” characterizing it as effectively rendering Bitcoin quantum-safe immediately. Bitcoin ESG specialist Daniel Batten challenged this characterization, describing the claim as excessive.

    Batten highlighted that revealed public keys and inactive wallets remain unaddressed within the research. This encompasses roughly 1.7 million Bitcoin secured in early-generation addresses vulnerable to potential quantum computer exploitation.

    Progress on Permanent Solutions

    The QSB development team recognized their system as an emergency contingency option. They emphasized that protocol-level modifications continue representing the optimal long-term approach.

    BIP-360, designed to implement quantum-resistant signatures via soft fork, stands as the leading candidate for comprehensive protection. However, its deployment schedule remains undetermined. Prediction market participants currently assign minimal probability to activation within the current year.

    Bitcoin’s historical governance patterns indicate extended implementation periods. Taproot, a prior enhancement, required approximately seven and a half years from initial conception through final deployment.

    Google released research in March indicating quantum computers might break Bitcoin’s cryptographic protections using fewer computational resources than earlier estimates suggested, intensifying discussion around preparedness.

    Lightning Labs CTO Olaoluwa Osuntokun independently released a quantum “escape hatch” prototype this week enabling users to demonstrate wallet ownership through seed phrases without exposing the actual phrase.
