StarkWare says quantum-safe Bitcoin transaction cost drops 79% to $67

Summary · why it matters

The processing cost for preparing quantum-resistant Bitcoin transactions has fallen to under $67, down from about $320, a reduction of roughly 79%, according to benchmark tests. The improvement follows the Quantum-Safe Bitcoin Optimization Challenge, which StarkWare launched together with Yukon Research and Eigen Labs on September 16, producing 62 accepted improvements covering the two computing tasks needed to prepare QSB transactions. The first QSB transaction was mined and confirmed on the blockchain on August 26, taking about 3,100 GPU hours on roughly 100 GPU machines and submitting the transaction through MARA's Slipstream service. Meanwhile, Avihu Levy, a researcher at StarkWare, published the Quantum-Safe Bitcoin design in April, describing it as a last-resort measure that uses hash-based protection without changing Bitcoin's consensus rules. StarkWare continues to back soft forks as the long-term answer for broad quantum protection.

EU Financial Authorities Urge Early Action on Quantum Computers, Citing Major Risks to Cryptography

The European Banking Authority, the European Insurance and Occupational Pensions Authority, and the European Securities and Markets Authority published a joint risk report on September 23, warning that quantum computers pose a serious risk to the cryptography protecting communications, transactions, databases, and blockchains. They said the threat could materialize sooner than the commercialization of quantum technology, and called on financial institutions and market participants to prepare for the rapid development of quantum computers. In crypto assets, ownership is proven through digital signatures using public and private keys, but future quantum computers could derive a private key from a public key and impersonate the owner to move assets. CoinDesk, citing data from CryptoQuant, reported that roughly 6.9 million bitcoins could be exposed to quantum attacks. The EU has already set out a plan to migrate to post-quantum cryptography, asking member states to begin the transition by the end of 2026 and aiming to protect high-risk sectors by the end of 2030 at the latest. On September 10, Eigen Labs published research showing that the key computational processing required for a quantum attack on the cryptography used by Bitcoin and Ethereum could be reduced by more than 50 percent in resource terms compared with previous estimates.

Coinbase Launches Fixed-Rate Bitcoin Loans on Morpho, Adds Post-Quantum Custody

Coinbase Global has introduced enterprise-scale, fixed-rate Bitcoin-backed loans using the Morpho protocol for on-chain lending, alongside a post-quantum security architecture designed to harden its Bitcoin custody against future quantum computing threats. The fixed-rate loans target institutional borrowers seeking predictable on-chain financing terms rather than variable-rate crypto credit arrangements. The company said the two initiatives are only one part of its broader crypto infrastructure push, feeding directly into its role as an infrastructure provider for institutional clients that want more predictable and security-focused crypto services. The early tell for investors will be whether Coinbase starts disclosing specific metrics around Morpho-based loan balances, institutional borrower adoption and quantum-ready custody features in upcoming quarterly updates, instead of leaving these initiatives as purely technical announcements.

Quantum eMotion Unit SKV Wins USPTO Notice of Allowance for SecureKey Patent

Quantum eMotion Corp. said its recently acquired subsidiary SKV Technology Inc. has received a Notice of Allowance from the United States Patent and Trademark Office for U.S. patent application No. 18/819,165 covering its SecureKey technology. A Notice of Allowance means the USPTO has determined the application is entitled to proceed toward issuance as a U.S. patent, subject to completion of applicable administrative requirements. SecureKey is a cryptographic technology designed to manage and protect cryptographic key material during cryptographic operations. Separately, the SecureKey Cryptographic Module is undergoing validation under the FIPS 140-3 framework administered through the Cryptographic Module Validation Program of the U.S. National Institute of Standards and Technology and the Canadian Centre for Cyber Security, and currently holds an Implementation Under Test designation, which indicates the module has entered testing with an accredited laboratory but does not constitute FIPS 140-3 validation or certification. Chief Executive Officer Dr. Francis Bellido said the Notice of Allowance is an important step in the patent process for the SecureKey technology acquired through SKV, while the module continues through FIPS 140-3 validation as a separate process. The company said it will provide further information following formal issuance of the patent or upon material developments in the FIPS 140-3 validation process.
