Bitcoin Developer Proposes Hard Fork to Protect BTC From Quantum Computing Threats

Bitcoin could be headed for its most sweeping cryptographic overhaul yet if a new proposal gains traction.

A draft Bitcoin Improvement Proposal (BIP) titled Quantum-Resistant Address Migration Protocol (QRAMP) has been introduced by developer Agustin Cruz. It outlines a plan to enforce a network-wide migration of BTC from legacy wallets to ones secured by post-quantum cryptography.

Quantum computing involves moving away from a process reliant on binary code, ones and zeros, and exponentially increasing computing power by employing Quantum bits (qubits) that exist in multiple states simultaneously. Such a jump in power is expected to threaten modern computing encryption built by classic machines.

The proposal suggests that after a predetermined block height, nodes running the updated software would reject any transaction trying to spend coins from an address using ECDSA cryptography, which could theoretically make it vulnerable to quantum attacks.

A hard fork debate

Bitcoin currently relies on algorithms, including SHA-256 for mining and the Elliptic Curve Digital Signature Algorithm (ECDSA) for signatures. Per Cruz, legacy addresses that haven’t yet transacted are protected by additional layers, while those that have exposed their public keys—necessary to conduct transactions—may now be vulnerable “if sufficiently powerful quantum computers emerge.”

The move would require a hard fork, which is likely going to be a tall ask from the community. A hard fork refers to a change to a blockchain that renders an older version incompatible.

«I admire the effort but this will still leave everyone who doesn’t migrate’s coins vunerable, including Satoshi’s coins,» said one Reddit user about the new proposal.

«Bitcoin could implement a post quantum security for all coins but that would need a hard fork, which due to bitcoin’s history and the mantra repeated by maxis that would create a new coin and would not be bitcoin anymore.»

Preventive measure

The proposed solution sets a migration deadline to lock those funds unless they’re moved to a more secure wallet. This proposal isn’t a response to any imminent breakthrough in quantum computing. Instead, it’s a preventive measure, yet it comes a little over a month after Microsoft unveiled Majorana 1, a quantum processing unit designed to scale to a million qubits per chip.

During a migration window, users would still be able to move funds freely. The BIP calls for wallet developers, block explorers and “other infrastructure” to build tools and warnings to help users comply.

After the deadline, non-upgraded nodes could fork from the network if they continue accepting legacy transactions.

This is not the first time someone has suggested a mechanism to defend Bitcoin from quantum computing threats. Most recently, BTQ, a startup working to build blockchain technology that can withstand attacks from quantum computers, has proposed an alternative to the Proof of Work (PoW) algorithm involving quantum technology.

In its research paper, BTQ proposed a method called Coarse-Grained Boson Sampling (CGBS). This process uses light particles (bosons) to generate unique patterns—samples—that reflect the blockchain’s current state instead of hash-based mathematical puzzles.

However, this proposal would also require a hard fork involving miners and nodes replacing their existing ASIC-based hardware with quantum-ready infrastructure.

Crypto trading firm Keyrock said it’s expanding into asset and wealth management by acquiring Turing Capital, a Luxembourg-registered alternative investment fund manager.

The deal, announced on Tuesday, marks the launch of Keyrock’s Asset and Wealth Management division, a new business unit dedicated to institutional clients and private investors.

Keyrock, founded in Brussels, Belgium and best known for its work in market making, options and OTC trading, said it will fold Turing Capital’s investment strategies and Luxembourg fund management structure into its wider platform. The division will be led by Turing Capital co-founder Jorge Schnura, who joins Keyrock’s executive committee as president of the unit.

The company said the expansion will allow it to provide services across the full lifecycle of digital assets, from liquidity provision to long-term investment strategies. «In the near future, all assets will live onchain,» Schnura said, noting that the merger positions the group to capture opportunities as traditional financial products migrate to blockchain rails.

Keyrock has also applied for regulatory approval under the EU’s crypto framework MiCA through a filing with Liechtenstein’s financial regulator. If approved, the firm plans to offer portfolio management and advisory services, aiming to compete directly with traditional asset managers as well as crypto-native players.

«Today’s launch sets the stage for our longer-term ambition: bringing asset management on-chain in a way that truly meets institutional standards,» Keyrock CSO Juan David Mendieta said in a statement.

Gemini Shares Slide 6%, Extending Post-IPO Slump to 24%

Gemini Space Station (GEMI), the crypto exchange founded by Cameron and Tyler Winklevoss, has seen its shares tumble by more than 20% since listing on the Nasdaq last Friday.

The stock is down around 6% on Tuesday, trading at $30.42, and has dropped nearly 24% over the past week. The sharp decline follows an initial surge after the company raised $425 million in its IPO, pricing shares at $28 and valuing the firm at $3.3 billion before trading began.

On its first day, GEMI spiked to $45.89 before closing at $32 — a 14% premium to its offer price. But since hitting that high, shares have plunged more than 34%, erasing most of the early enthusiasm from public market investors.

The broader crypto equity market has remained more stable. Coinbase (COIN), the largest U.S. crypto exchange, is flat over the past week. Robinhood (HOOD), which derives part of its revenue from crypto, is down 3%. Token issuer Circle (CRCL), on the other hand, is up 13% over the same period.

Part of the pressure on Gemini’s stock may stem from its financials. The company posted a $283 million net loss in the first half of 2025, following a $159 million loss in all of 2024. Despite raising fresh capital, the numbers suggest the business is still far from turning a profit.

Compass Point analyst Ed Engel noted that GEMI is currently trading at 26 times its annualized first-half revenue. That multiple — often used to gauge whether a stock is expensive — means investors are paying 26 dollars for every dollar the company is expected to generate in sales this year. For a loss-making company in a volatile sector, that’s a steep price, and could be fueling investor skepticism.
