Bitcoin’s Quantum Security Crisis: 6.9 Million BTC at Risk, Governance Challenges Impede Response
According to CoinDesk, while quantum computers cannot break Bitcoin’s mining mechanism or blockchain ledger, they could potentially crack the elliptic curve cryptography (ECC) that secures wallet ownership—using Shor’s algorithm. Currently, approximately 6.9 million BTC—roughly one-third of the total supply—are at potential risk because their public keys are already visible on-chain; this includes Satoshi Nakamoto’s estimated early holdings of about 1 million BTC. Transactions generated after Ethereum’s 2021 Taproot upgrade are similarly exposed due to public key disclosure. Ethereum has maintained an official post-quantum migration plan since 2018, with four full-time teams and over ten independent development groups, and operates a dedicated progress website at pq.ethereum.org. In contrast, Bitcoin currently lacks a unified roadmap for quantum resistance: existing proposals such as BIP-360 and BitMEX Research’s detection framework have not gained broad support among core developers. Prominent Bitcoin advocate Nic Carter has bluntly labeled Bitcoin’s quantum response “the worst,” while Blockstream CEO Adam Back acknowledges that current quantum systems remain confined to laboratory settings—but still endorses deploying optional upgrade paths in advance. Analysts note that Bitcoin’s decentralized governance culture makes coordinating large-scale security upgrades extremely difficult, and resolving historical issues—such as how to handle Satoshi’s holdings—presents a particularly thorny dilemma. A related Google paper warns that once quantum attacks become feasible, the window for effective response may already have closed.
Adam Back Advocates Optional Quantum-Resistant Upgrades, Diverging from BIP-361’s Mandatory Freeze Proposal
According to Decrypt, Blockstream CEO Adam Back stated at Paris Blockchain Week that he supports advancing Bitcoin’s quantum resistance upgrade on an opt-in basis, opposing proposals to forcibly freeze quantum-vulnerable addresses. He emphasized that “preparation well in advance is far safer than scrambling to respond during a crisis,” and noted that the Bitcoin community possesses strong coordination capabilities to rapidly address critical vulnerabilities. Previously, developer Jameson Lopp and five others proposed BIP-361 (“Post-Quantum Migration and Legacy Signature Sunset”), which advocates phasing out quantum-vulnerable addresses over five years and ultimately freezing coins held in unmigrated addresses—including approximately 1.7 million bitcoins held by Satoshi Nakamoto.
Adam Back advocates for Bitcoin to promptly advance optional post-quantum upgrades and opposes pre-emptively freezing vulnerable addresses.
According to CoinDesk, Adam Back, CEO of Blockstream, stated at Paris Blockchain Week that Bitcoin developers should move forward early with optional post-quantum upgrades—even though practical quantum computers remain far from realization. He noted that Taproot’s flexible design supports integrating new post-quantum signature schemes without affecting existing users. Previously, Jameson Lopp and others proposed BIP-361, aiming to phase out quantum-vulnerable addresses over five years and freeze bitcoins in addresses that fail to complete the migration. Adam Back believes the Bitcoin community can rapidly coordinate a response in an emergency—without needing to predefine freezing arrangements.
Bitcoin Security Alliance Officially Established, Nine Major Institutions Pledge $15 Million Over Three Years
According to the official press release, Anchorage Digital, ARK Invest, BlackRock, Block, Blockstream, Coinbase, Fidelity Digital Assets, Galaxy, and Strategy, nine leading financial institutions and Bitcoin companies, jointly announced the establishment of the Bitcoin Security Consortium on July 23, 2026. The members independently committed to contributing a total of $15 million over the next three years to support long-term security research for the Bitcoin network, with a focus on development work in the field of post-quantum cryptography. The consortium's daily affairs are coordinated on a voluntary basis by Brink Executive Director Mike Schmidt; it will not intervene in protocol development or specific change decisions and will regularly release Bitcoin security status reports to investors and the public.
Michael Saylor Posts 110 Reasons Against Bitcoin BIP-110 Soft Fork Proposal
According to Decrypt, Strategy Executive Chairman Michael Saylor recently published a long article titled "110 Reasons BIP 110 Is a Bad Idea," comprehensively opposing the Bitcoin BIP-110 soft fork proposal. BIP-110 aims to temporarily restrict non-financial data such as Ordinals and inscriptions from being on-chain by tightening consensus rules. Supporters (including developer Luke Dashjr and the Bitcoin Knots camp) characterize it as an "anti-spam transaction" measure. Saylor raised three core objections to this: • Precedent Risk: Bitcoin cannot identify data "intent"; blocking a type of usage via consensus means will set a dangerous template for future innovations targeting privacy tools, stablecoin settlements, etc., "The restriction period is about one year, but the precedent exists permanently" • Activation Mechanism Risks: BIP-110 lowers the miner signaling threshold from 95% to 55%, and removes the proposal natural expiration option. With the current signaling rate below 1%, inconsistent execution could lead to network split • Classification Controversy: Saylor believes "spam" is not a consensus-layer concept; dislike for a certain type of usage does not equal invalidity. "Bitcoin does not need guardians of purity, but guardians of neutrality" Saylor's stance aligns with Blockstream CEO Adam Back, Casa Co-founder
Michael Saylor: Publishes 110-Point Article Opposing Bitcoin BIP-110
Odaily Strategy Executive Chairman Michael Saylor published a 110-point article opposing the proposed Bitcoin soft fork BIP-110. BIP-110 plans to tighten Bitcoin's consensus rules within about a year, restricting the technology used for embedding arbitrary data, targeting non-financial data such as Ordinals and inscriptions. Michael Saylor stated that BIP-110 would invalidate currently valid transactions that pay fees through consensus changes, and claimed that Bitcoin cannot differentiate data intent. He believes that including a specific use case within the consensus layer restrictions would set a governance precedent. While the specific restrictions would expire in about a year, the precedent would not disappear. He also opposed the proposal's activation design, stating it lowers the miner signaling threshold from the 95% used in earlier soft forks to 55%, and removes the option that typically allows proposals to naturally expire. Data from a proposal monitoring dashboard shows current signaling support is below 1%. The mandatory signaling window for BIP-110 is scheduled to open in August, with a target activation date around September 1st. Michael Saylor's stance aligns with Blockstream CEO Adam Back, Casa's Jameson Lopp, and Bitcoin proponent Samson Mow. Opponents include developer Luke Dashjr and the Bitcoin Knots camp.
BIP-110 Bitcoin Data Limitation Proposal Nears Deadline with 0% Miner Support
the Bitcoin BIP-110 proposal is approaching its early August deadline, with miner support currently below 1%. In the current cycle, support stands at 0%, and no major mining pools have signaled in favor. BIP-110, officially titled "Reduced Data Temporary Soft Fork," aims to restrict OP_RETURN data capacity within one year, prohibit most arbitrary data writes exceeding 256 bytes, and limit certain script formats primarily used for data storage. Strategy founder Michael Saylor and Blockstream co-founder Adam Back have both publicly opposed BIP-110. Data shows that BIP-110 adopts a user-activated soft fork mechanism, setting a 55% miner signal threshold. The proportion of nodes running BIP-110 software remains in the single digits, primarily from Bitcoin Knots users. The current signaling cycle for this proposal is expected to end near block height 959,615, entering a voluntary lock-in period around early August, with activation planned for approximately September. If broad support remains absent by then, it could lead to a small number of nodes forming a split chain.

BlackRock, Coinbase, and Others Establish a $15 Million Bitcoin Quantum Defense Fund
Odaily Odaily News: BlackRock, Coinbase, Strategy, Anchorage Digital, ARK Invest, Block, Blockstream, Fidelity Digital Assets, and Galaxy have formed the Bitcoin Security Consortium, committing a combined $15 million over three years to fund Bitcoin security research and open-source development focused on quantum computing defense. The consortium does not hold or distribute funds; each member directly selects the developers and researchers they will fund. The consortium stated it will not direct Bitcoin development or take positions on protocol changes. Mike Schmidt from the developer funding non-profit Brink will coordinate related efforts as a volunteer. Currently, there is no quantum computer capable of breaking Bitcoin's cryptography. Approximately 6.9 million BTC, worth $450 billion, are held in addresses that could be affected if such a quantum computer emerges. Remediation would require coordination among wallets, exchanges, miners, users, and other parties. Related work includes proposals such as BIP 360, which designs a new output type to limit public key exposure and accommodate post-quantum signature schemes. Robert Mitchnick, Head of Digital Assets at BlackRock, stated that Core developers are doing important work and that this organization will provide more funding for Bitcoin's long-term security.
