BlackRock Warns Bitcoin And Ethereum Investors About Quantum Computing
BlackRock has entered the quantum-computing debate with a new report warning that future breakthroughs could eventually threaten the cryptography securing Bitcoin, Ethereum and much of the broader digital-asset market. The firm’s central message is not that blockchains face an immediate crisis, but that the industry needs to begin post-quantum migration before “Q-Day” becomes a live security event. The report , titled “Quantum Computing and Blockchains,” was authored by Will Su, Head of Digital Assets Research at BlackRock, Inish Crisson, Senior Software Engineer at Aladdin Digital Assets Lab, and Robert Mitchnick, BlackRock’s Head of Digital Assets. It frames quantum computing as both a cybersecurity risk and a potential test of blockchain governance, particularly for networks that rely on elliptic curve cryptography for transaction signatures. “Quantum computing has been the subject of growing attention in recent years, particularly due to its implications for blockchains and many other elements of modern cyber infrastructure,” the authors wrote. “In our view, quantum computing is likely to be a manageable risk for blockchains, subject to the industry’s ability to upgrade swiftly and proactively to post-quantum cryptography in the coming years.” Bitcoin And Ethereum’s Core Risk BlackRock stresses that no functional Cryptographically Relevant Quantum Computer, or CRQC, exists today. But it says timelines have shifted. The report notes that Google has moved its post-quantum migration deadline to 2029, while IBM is targeting large-scale fault-tolerant quantum computing between 2029 and 2033. The main issue is not Bitcoin’s proof-of-work engine. BlackRock says Bitcoin’s SHA-256 hash function is “largely considered quantum-resistant,” with Grover’s algorithm offering only a quadratic speedup that could be absorbed by Bitcoin’s difficulty adjustment. The more relevant attack surface is ownership: the digital signatures that prove control over coins. Bitcoin and Ethereum currently rely on elliptic curve cryptography for key ownership and transaction authorization. Classical computers would need millions to billions of years to break 256-bit ECC, according to the report. A sufficiently powerful quantum computer using Shor’s Algorithm could change that equation by turning private-key recovery into a more tractable mathematical problem. “The foundations of modern-day cryptography become challenged in the quantum world,” BlackRock wrote. “This is not because quantum computers run faster. Rather, QCs are particularly efficient at teasing out hidden patterns in large datasets by leveraging unique properties of quantum physics and employing quantum algorithms to solve classically infeasible problems like ECDLPs in as little as days to minutes.” Bitcoin’s Migration Is Simpler, But Coordination Is Hard For Bitcoin, BlackRock argues that the technical scope of a post-quantum upgrade is narrower than for many other systems because the core task is replacing a digital-signature algorithm. The harder problem is social coordination across a decentralized network that deliberately avoids rapid or centralized change. The report says nearly 7 million BTC, or roughly 35% of circulating supply, may be vulnerable to long-range quantum attacks because public keys have already been exposed. That figure includes 1.9 million BTC in address types that expose unhashed public keys and another 5 million BTC in reused addresses that have revealed public keys in previous transactions while still holding UTXOs. BlackRock also highlights the unresolved debate around inactive or lost coins. It cites Chainalysis estimates that 2.3 million to 3.7 million BTC, or 11% to 19% of circulating supply, may be permanently lost. That includes roughly 1.1 million BTC in P2PK addresses widely believed to belong to Satoshi Nakamoto . “In our view, PQ migration for cryptocurrencies is eminently addressable from a technical standpoint, and the key challenge is one of timely coordination and implementation,” the report said. “The end-to-end process to build consensus around PQC protocols and timing, implement upgrades on the blockchain, and perform orderly migrations across the ecosystem will likely be a multi-year endeavor.” Ethereum Has A Roadmap, But More Moving Parts Ethereum’s situation is different. BlackRock says the network has a more clearly defined migration path , guided by the Ethereum Foundation, but faces greater technical complexity due to its proof-of-stake architecture, smart-contract environment, data layer and application-layer zero-knowledge systems. The report cites four Ethereum vulnerability areas identified by Vitalik Buterin in early 2026: BLS signatures in the consensus layer, KZG proofs in the data layer, externally owned account signatures, and zero-knowledge proofs in the application layer. In simpler terms, validator voting, data verification, user transactions and app-level proofs all touch quantum-vulnerable cryptographic assumptions. BlackRock points to Ethereum’s “L1 Strawmap,” a draft sequence of seven network updates and hard forks between 2026 and 2029, five of which directly address quantum vulnerabilities. These include native account abstraction, post-quantum signature precompiles, post-quantum validator keys, hash-based consensus signatures and a longer-term shift from KZG commitments toward STARK-based verification. A Wall Of Worry For Crypto BlackRock’s conclusion is measured. The report does not present quantum computing as an imminent existential threat to Bitcoin or Ethereum. It argues instead that quantum risk is one of the few remaining “walls of worry” for digital assets, and that successful post-quantum migrations could strengthen the sector over time. “Global cybersecurity infrastructure stands at an important inflection point as quantum computing advances,” the authors wrote. “Digital assets including Bitcoin and Ethereum are technically positioned for migration; a harder problem is coordinating timelines and rolling out upgrades across decentralized networks in an orderly manner. That said, it is a much less daunting task to upgrade current cryptographic systems, including Bitcoin, Ethereum, and others, to a quantum-secure standard than it is to build a CRQC from where quantum computing progress stands today.” At press time, BTC traded at $62,629.

Bitcoin Flashes One Of Its Rarest Demand Signals In Six Years – Details
Bitcoin is holding above $62,000 after the massive drop that defined last week’s market action and erased months of recovery progress in a matter of days. The price is stabilizing — but analyst MorenoDV has published a demand analysis that places the current market conditions in a historical context that makes the stability feel considerably more fragile than the held price level suggests. Related Reading: XRP Just Printed A Rare Binance Signal As Market Volatility Accelerates Bitcoin demand has entered one of its most extreme contraction regimes since 2019. The 30-day growth of combined spot and perpetual futures demand has fallen toward -650,000 BTC — a threshold that has been reached only three times across the chart’s entire history. The rarity of the reading is the first signal that the current environment is not a routine demand slowdown but something structurally more severe. The architecture of the contraction is what makes MorenoDV’s analysis particularly significant. Spot demand and perpetual futures demand are contracting simultaneously — meaning the weakness is not isolated to speculative leverage unwinding. Organic buyers who would normally absorb declining prices through spot purchases and derivatives participants who express directional conviction through futures exposure are both withdrawing at the same time. The two demand streams that together provide Bitcoin’s marginal buying capacity are disappearing in parallel rather than one offsetting the other. What remains is a market with fewer buyers, less capacity to absorb selling pressure, and a demand structure that has only looked this extreme on three previous occasions in Bitcoin’s modern market history. Three Times in History and the Previous Two Were Not Bottoms Yet The MorenoDV analysis applies the historical framework that prevents the extreme demand contraction reading from being interpreted as automatic capitulation confirmation. The two previous occasions when combined demand fell toward the -650,000 BTC threshold carried specific and instructive implications that the current setup should be evaluated against. Bitcoin Spot and Perpetual Futures Demand Growth | Source: CryptoQuant The first breakdown toward this level occurred before the COVID crash — demand deterioration was already developing before the final liquidity shock arrived. The metric reaching extreme contraction was not the bottom. It was the early warning that preceded the actual capitulation event that followed weeks later. The 2022 bear market showed a similar distinction. Extreme demand contraction reflected deep structural deterioration rather than marking the floor. The subsequent interactions with higher support zones occurred as the market moved through its broader bottoming and rebuilding process — a prolonged sequence rather than a single decisive moment. The current setup therefore resembles the beginning of a final cleansing phase more than a confirmed reversal. MorenoDV identifies the most probable path as an initial expansion in volatility followed by what the analysis describes as price anesthesia — weak momentum, compressed activity, and prolonged sideways action that exhausts remaining participants without delivering the dramatic capitulation event that would provide psychological closure. That phase may prove more damaging than the sell-off itself. Sharp declines create fear but also resolve — they force decisions and clear positions. Extended sideways action at depressed levels erodes conviction gradually, tests patience beyond its limits, and tends to shake out holders who survived the initial drop but cannot endure the silence that follows it. Related Reading: Ethereum OG Nails The Crash: Sells $188M, Buys Back Lower Bitcoin Price Testing Critical Demand Bitcoin is attempting to stabilize above the $62,000 level after one of the sharpest selloffs of the cycle erased the May recovery and drove price back into a critical long-term support region. On the weekly chart, BTC is currently trading directly above the 100-week moving average (red line), which has acted as a major support level throughout previous corrective phases. The fact that buyers stepped in near this area suggests that long-term participants still view the zone as attractive despite the recent weakness. Bitcoin testing key demand level | Source: BTCUSDT chart on TradingView However, the broader technical structure remains fragile. The rejection from the $72,000–$74,000 resistance zone confirmed that previous support has now become resistance. Bitcoin failed to reclaim that range and subsequently broke below the consolidation area that held between March and May, triggering a rapid decline toward the current support region. Related Reading: Why Did Bitcoin Crash? On-Chain Data Points To One Missing Ingredient The key level to watch remains the $60,000–$63,000 region. Holding above it would preserve the possibility of a prolonged base formation. A decisive break below that zone could expose Bitcoin to a deeper retracement toward the mid-$50,000s. To regain momentum, bulls must reclaim the former support zone near $66,000 and eventually challenge resistance around $72,000. Until then, the trend remains defensive despite the recent bounce.

Bitcoin Layer 2 Project Botanix to Shut Down on July 9, Citing Market Realities
BitcoinWorld Bitcoin Layer 2 Project Botanix to Shut Down on July 9, Citing Market Realities Botanix, a Bitcoin Layer 2 project that aimed to bring decentralized finance (DeFi) functionality to the Bitcoin network, has announced it will cease operations on July 9. The decision, shared via a post on X, comes after four years of development and an assessment that its business model is no longer sustainable in the current market landscape. Why Botanix Is Shutting Down According to the project’s statement, Botanix struggled to validate sufficient demand for a Bitcoin-native blockchain solution. The team noted that users have increasingly favored convenience over decentralization, with most demand for Bitcoin DeFi already being met by established alternatives such as Wrapped Bitcoin (WBTC) and general-purpose Layer 2 environments on other networks. This shift, combined with a challenging funding environment for Bitcoin-focused infrastructure projects, made continued operations unviable. Timeline and User Impact Botanix has instructed all existing users to withdraw their funds before the July 9 shutdown date. The project did not specify whether any assets would be recoverable after that deadline, emphasizing the urgency for users to act promptly. The closure affects users who had deposited funds into Botanix’s testnet or any associated applications built on the platform. What This Means for Bitcoin DeFi The shutdown highlights a broader challenge for Bitcoin-centric DeFi projects: competing against the liquidity and developer ecosystems of Ethereum-based L2s and sidechains. While Bitcoin remains the largest cryptocurrency by market capitalization, its scripting limitations and slower adoption of smart contract capabilities have made it difficult for native L2 projects to gain traction. WBTC, which tokenizes Bitcoin on Ethereum, has captured a significant share of Bitcoin DeFi activity, offering users access to Ethereum’s robust DeFi infrastructure without leaving the Bitcoin ecosystem. Conclusion Botanix’s closure serves as a cautionary tale for Bitcoin Layer 2 projects attempting to carve out a niche in a market dominated by more flexible and widely adopted platforms. For users, the key takeaway is to withdraw funds promptly and to evaluate the long-term viability of any DeFi protocol before committing assets. As the crypto industry continues to mature, projects that fail to achieve product-market fit or secure sustainable revenue streams are likely to face similar outcomes. FAQs Q1: What is Botanix? Botanix was a Bitcoin Layer 2 project designed to enable decentralized finance (DeFi) applications on the Bitcoin network. It operated as a sidechain that aimed to bring smart contract functionality to Bitcoin while maintaining security through Bitcoin’s consensus. Q2: Why did Botanix fail? The project cited a lack of user demand for a Bitcoin-native DeFi solution, with most users preferring convenience over decentralization. Competition from Wrapped Bitcoin (WBTC) and general-purpose Layer 2 environments on other blockchains also eroded its potential user base. Q3: What should Botanix users do now? All users must withdraw their funds from the Botanix platform before July 9, 2025. After that date, the project will cease operations, and funds may become inaccessible. Users should check the official Botanix channels for detailed withdrawal instructions.

This mechanism is intended to offset the negative market impact of the hack and potentially restore value to token holders. The project also confirmed it is preparing a formal recovery plan for victims directly affected by the exploit. Implications for the Crypto Security Landscape This incident adds to a growing list of crypto projects that have turned to bounty programs as a recovery tool. While bounties can be effective in mobilizing community resources, they also highlight the persistent vulnerability of DeFi and blockchain projects to sophisticated attacks. The success of Humanity’s recovery effort will depend heavily on the speed of information sharing with exchanges and the willingness of the attacker to negotiate or make a mistake that reveals their identity. For investors, the announcement provides a clear signal that the project is actively working to mitigate losses, though the final outcome remains uncertain. Conclusion Humanity’s response to its recent hack combines immediate technical countermeasures with a financial incentive for information. The 1 million USDT bounty and the commitment to a token buyback represent a structured attempt to restore confidence and recover value. As the situation develops, the effectiveness of the tracking system and the cooperation of external exchanges will be key factors in determining whether the stolen funds can be returned. FAQs Q1: How does the 1 million USDT bounty work? Anyone with information that leads to the recovery of the stolen funds can claim the bounty. The project has not yet specified the exact criteria for reward distribution, but it is likely tied to the percentage of funds recovered or the critical nature of the tip provided. Q2: What happens to the recovered funds? All recovered funds will be used for a buyback of the H token, which could help support the token’s price and reduce the overall impact of the hack on the project’s ecosystem. Q3: Is there a recovery plan for individual victims? Yes, Humanity has stated it is preparing a recovery plan specifically for victims of the hack. The details of this plan have not yet been released, but it is expected to outline how affected users can submit claims or receive compensation.

US Court Sentences Washington Man to 5 Years for $97.1 Million Crypto Money Laundering Scheme
BitcoinWorld US Court Sentences Washington Man to 5 Years for $97.1 Million Crypto Money Laundering Scheme A federal court in the United States has sentenced Geoffrey K. Auyeung, a resident of Seattle, Washington, to five years in prison for orchestrating a cryptocurrency money laundering operation that processed approximately $97.1 million in criminal proceeds between 2022 and 2024, as reported by Decrypt. The Scheme: Oil and Gas Fraud Masked by Crypto According to prosecutors, Auyeung acted as a key financial intermediary for a fraudulent organization that solicited investments in oil and natural gas ventures. His role was to receive funds from victims, convert them into cryptocurrencies such as Bitcoin (BTC), Ethereum (ETH), and Tether (USDT), and then transfer the digital assets to accomplices, effectively obscuring the money trail. The scheme targeted investors with promises of high returns from energy sector projects, a classic investment fraud model updated with cryptocurrency layers to evade detection. The laundering operation ran for roughly two years before law enforcement intervened. Legal Implications and Sentencing Details The five-year sentence reflects the severity of the crime, which involved sophisticated financial techniques to hide the origin of illicit funds. Money laundering cases involving cryptocurrency have drawn increased attention from U.S. authorities, who are developing specialized investigative capabilities to trace blockchain transactions. Prosecutors emphasized that Auyeung was not merely a passive participant but an active facilitator who understood the laundering mechanism. The court also considered the scale of the operation, which exceeded $97 million in laundered funds. What This Means for Crypto Regulation This case underscores the growing legal risks for individuals who use cryptocurrency to facilitate financial crimes. U.S. regulators, including the Department of Justice and the Financial Crimes Enforcement Network (FinCEN), have signaled that crypto mixing and conversion services will face heightened scrutiny. The sentencing serves as a deterrent to others who might consider using digital assets to mask fraudulent schemes. For the broader crypto industry, the case reinforces the importance of compliance with anti-money laundering (AML) regulations. Exchanges and wallet providers are increasingly required to implement know-your-customer (KYC) procedures and report suspicious transactions. Conclusion The sentencing of Geoffrey Auyeung to five years in prison marks a significant enforcement action in the fight against cryptocurrency-enabled financial crime. It demonstrates that U.S. courts are prepared to impose substantial penalties on those who exploit digital assets for money laundering, particularly when the underlying fraud involves traditional investment scams. As regulatory frameworks evolve, cases like this will likely shape the legal landscape for crypto-related financial offenses. FAQs Q1: What was Geoffrey Auyeung convicted of? He was convicted for his role in a cryptocurrency money laundering scheme that processed approximately $97.1 million in proceeds from an oil and gas investment fraud. Q2: How did the money laundering operation work? Auyeung received funds from victims, converted them into Bitcoin, Ethereum, and Tether to obscure the money trail, and then transferred the crypto assets to his accomplices. Q3: What is the significance of this case for crypto regulation? The case highlights increased U.S. enforcement against crypto-enabled financial crimes and reinforces the need for exchanges and individuals to comply with anti-money laundering regulations.
