AmericanFortress Proposes Quantum-Safe Wallet Security Without Moving Funds

AmericanFortress has proposed a post-quantum cryptography scheme aimed at protecting cryptocurrency wallets from future quantum attacks—without forcing users to move funds, rotate keys, or change wallet addresses. The company’s approach centers on cryptographic proofs tied to a wallet’s original seed phrase, according to a technical paper published on the Cryptography ePrint Archive. The proposal comes at a time when the industry is actively planning for a potential “migration” away from today’s elliptic-curve cryptography. While quantum computers capable of breaking these schemes are not available today, analysts have warned that the long lead time for upgrades makes preparation urgent. Earlier coverage cited a Bloomberg analysis suggesting as much as $470 billion in Bitcoin could become vulnerable under sufficiently capable quantum machines. Key takeaways AmericanFortress says its post-quantum wallet protection keeps existing wallet addresses unchanged and avoids user-side migratio...

Kraken Enables Retail Access to Jersey Mike’s IPO via Tokenized Shares

Kraken is expanding its tokenized-IPO offering to retail investors with access to Jersey Mike’s upcoming public listing. The exchange says eligible US customers will be able to request allocations of Jersey Mike’s shares at the IPO price, while customers outside the US can request tokenized shares designed to be backed 1:1 by the underlying stock. The development adds another well-known US consumer brand to the small but growing menu of tokenized equities accessible through major crypto venues. It also comes after recent friction in similar campaigns—most notably around SpaceX—highlighting that investor demand for tokenized IPO access can exceed the supply of underlying shares. Key takeaways Kraken will let eligible US retail users submit interest in book-entry Jersey Mike’s shares at the IPO price, while global users can request tokenized shares backed 1:1 by the stock. Tokenized shares will trade 24 hours a day, five days a week on Kraken and participating xStocks Alliance platfo...

Bitcoin Slides Below $63K as Asia Chip Selloff Spills Over to U.S.

Bitcoin slipped to ten-day lows at the opening of Wall Street on Tuesday, extending a broader risk-off move that followed a sharp sell-off in Asia-linked equities. As traders digested renewed pressure on global technology and AI supply chains, BTC trading weakened alongside US market futures before and during the start of US hours. Crypto positioning also took a hit. Liquidation data indicates long positions were forced out quickly, with CoinGlass reporting more than $510 million wiped out over roughly 24 hours as the decline accelerated. Meanwhile, key benchmarks in semiconductor-heavy markets fell hard—underscoring how strongly crypto is still reacting to traditional market stress. Key takeaways Bitcoin’s move to ten-day lows coincided with a US equities sell-off after steep declines in Asian markets. Semiconductor stocks led the reversal in Asia, with South Korea’s KOSPI closing down 10.8% in a day. Crypto derivatives liquidations for long positions surpassed $510 million over...

Core Scientific Revenue Surges to Double in Q2 on AI Colocation Expansion

Core Scientific has reported a sharp rebound in its second-quarter financial performance as its data-center colocation business—built to support artificial intelligence (AI) and high-performance computing (HPC)—continues to drive results after the miner’s shift away from a Bitcoin-only model. In earnings released Tuesday, the company said Q2 revenue rose to $164.2 million , compared with $78.6 million in the same quarter a year earlier. Colocation revenue made up the overwhelming majority of that figure, climbing to $136.7 million from $10.6 million , while gross profit increased to $70 million from $5 million . Key takeaways Core Scientific’s revenue more than doubled in Q2, with colocation now the dominant earnings engine. AI- and HPC-oriented infrastructure appears increasingly central to the company’s profit trajectory, as gross profit jumped alongside colocation revenue. Despite strong topline growth, Core Scientific posted a large net loss driven largely by a non-cash ac...

Markets Watch BoJ Meeting as Yen Holds Near 40-Year Lows vs USD

Japan’s next monetary policy decision is coming into sharper focus as the yen keeps sliding toward fresh 40-year lows against the US dollar. With the Bank of Japan (BoJ) scheduled to meet on July 31, markets are weighing whether policymakers will pause at current levels—or signal further tightening as the currency weakens. The immediate question for global markets, and particularly for crypto traders, is how much pressure a yen slide can add through “carry trade” dynamics. When Japanese rates stay low and the yen depreciates, borrowing in yen to fund riskier assets can expand. But if conditions shift—especially if the yen moves abruptly—those positions can unwind quickly, tightening liquidity and often hitting highly leveraged markets. Key takeaways USD/JPY is nearing new 40-year highs, edging toward the 164 area after last week’s record set, according to TradingView. The BoJ meets on July 31 with its policy rate currently at 1.0%, the highest since September 1995. Market pricing...

Why Some DeFi Survivors of 2022 Are Now Shutting Down

Decentralized finance is shedding projects again. DeFi dashboard Zapper announced it will shut down after nearly seven years, adding to a wave of closures and wind-downs that have marked 2026 across multiple segments of the industry. Earlier this year, Bitcoin DeFi platform Botanix , Solana portfolio tracker Step Finance , DeFi analytics platform Parsec , and DEX aggregator Odos Protocol also moved toward shutdown or completion of operations. RootData has tracked 101 “dead” crypto projects in 2026 as of July 26, and observers say DeFi accounts for more than half of those failures. Key takeaways DeFi closures in 2026 aren’t explained solely by “bear market blues.” Analysts argue capital has shifted to different parts of the ecosystem rather than disappearing. Concentration may be easing, not intensifying. Artemis data cited in the report suggests leading protocols hold smaller shares than they did two years ago. Fees and revenue matter more than TVL for diagnosing which DeFi...

CZ Supports ASEAN Crypto License Passporting to Expand Access

Binance co-founder Changpeng “CZ” Zhao has endorsed a proposal for “license passporting” across ASEAN, arguing that crypto firms already authorized in one country should not have to restart the licensing process from scratch when expanding to neighboring markets. Zhao made the remarks during a fireside chat at the ASEAN Tech Summit Manila 2026 on Tuesday, backing an idea raised by Lito Villanueva, founding chair of FinTech Alliance PH. The core concept is a simplified approval pathway—while still allowing regulators to assess applicants—so that cross-border operations can be reviewed without duplicating every step of initial authorization. Key takeaways Zhao argues ASEAN could enable crypto license portability, reducing the need for firms to reapply from scratch in each member state. The proposal is framed as “simplified authorization” rather than full deregulation: regulators would still retain review power. ASEAN already uses cross-border frameworks in other financial areas, of...
