⚠️ D-Wave CEO warns quantum computing could break Bitcoin's PoW
D-Wave CEO Alan Baratz has warned that quantum computing will eventually be capable of breaking Bitcoin's proof-of-work protocol.
Baratz did not specify a timeline but framed the threat as a long-term systemic risk to the network's cryptographic foundations. The warning comes as the quantum computing industry accelerates, with D-Wave among the leading firms developing commercial quantum systems.
Bitcoin's security relies on SHA-256 hashing, which current classical computers cannot feasibly crack — but sufficiently advanced quantum machines could, in theory, undermine that assumption. The crypto community has debated quantum resistance for years, though no consensus upgrade path has been adopted.
⚖️ Russia drafts rules for crypto exchanges ahead of September launch
Russia's central bank has released draft regulations for cryptocurrency exchanges and digital asset depositories, setting the groundwork for the country's regulated crypto market expected to launch in September.
The Bank of Russia's proposals establish an operating framework covering market registration requirements alongside rules for exchanges and digital depositories. The draft rules represent a significant step toward formalizing crypto market infrastructure in one of the world's largest economies.
Russia has been accelerating its crypto regulatory agenda, with the September timeline marking a key milestone for bringing digital asset trading under official oversight.
⚖️ ESMA tightens MiCA rules for 270+ EU crypto firms
The European Securities and Markets Authority published a new Q&A document on July 29, 2026, aimed at clarifying outstanding ambiguities in the Markets in Crypto-Assets (MiCA) regulation — putting over 270 EU-based crypto firms on notice to adapt their compliance frameworks.
The guidance addresses areas where uncertainty had been accumulating across the industry, though firms now have a clearer regulatory baseline to work from. MiCA, the EU's landmark crypto regulatory framework, has been progressively taking effect, with full application covering crypto-asset service providers.
The move underscores ESMA's role as the primary enforcer of MiCA standards across EU member states, as European regulators push to establish the bloc as a structured and transparent environment for digital asset activity.
📊 Crypto Loses $24B as Bitcoin Slips Below $64,000
The crypto market shed nearly $24 billion in total market value as Bitcoin fell below the $64,000 mark, erasing a portion of recent recovery gains.
The selloff coincided with a broader rout in semiconductor stocks, which dampened risk appetite across markets. Volatile crypto assets bore the brunt of the decline as investors pulled back from higher-risk positions amid the equity weakness.
The episode highlights the continued sensitivity of crypto markets to macro and tech-sector sentiment, with Bitcoin's ability to hold key price levels remaining a focal point for broader market direction.
🟣 Solana raises block compute limit by 66% on mainnet
Solana is increasing its mainnet block compute limit from 60 million to 100 million compute units — a 66% jump in raw processing capacity — set to activate at the start of Epoch 1009 within 24 hours.
The upgrade expands how much computation the network can process per block, directly increasing throughput capacity for transactions, smart contracts, and DeFi activity running on the chain.
The change positions Solana to handle greater on-chain demand without architectural changes to the underlying protocol.
🔐 Fake Bitcoin wallet app on App Store costs users $1.8M
Three Apple users have filed a federal lawsuit against Apple after a fraudulent version of Sparrow Wallet appeared on the App Store and drained $1.835 million in Bitcoin from their accounts.
The case was filed in the US District Court for the Northern District of California. The plaintiffs allege Apple failed to prevent the malicious app from reaching users, directly challenging the company's claim that its App Store provides a safer software environment than competing platforms.
The incident adds to a growing list of crypto-related scams facilitated through fake wallet apps on major app stores, raising scrutiny over how effectively platforms vet listed applications.
