StarkWare Researcher Proposes Bitcoin Post-Quantum Transaction Scheme Without Soft Fork

According to The Block, Avihu Levy, a researcher at StarkWare, published a paper proposing the Quantum Safe Bitcoin (QSB) scheme, claiming it enables quantum-resistant transactions under Bitcoin’s existing script rules—without requiring a soft fork. This scheme replaces elliptic-curve cryptography with the RIPEMD-160 hash function via a “hash-to-signature” puzzle, thereby enhancing resilience against quantum attacks. The paper notes that QSB’s current per-transaction cost ranges from $75 to $150—significantly higher than today’s average transaction fee—and involves complex user experience; thus, it is recommended only as a “last resort.” The scheme remains constrained by script opcodes and size limits, and does not yet support all use cases—such as the Lightning Network. Compared to BIP-360—which requires protocol-level changes—QSB needs no modifications to the Bitcoin protocol, but remains experimental.

“Set 10 Major Goals First”: Whale Position Update—No Stop-Loss Triggered; ETH Short Position Generates $2.01M Unrealized Profit

According to on-chain analyst Ai Aunt (@ai_9684xtpa), renowned trader “Set 10 Big Goals First” (@Jason60704294) has updated his latest positions: his BTC short position has not only avoided triggering its stop-loss but has been increased to 2,567.49 BTC, with an average entry price of $71,554.61—currently showing a floating loss of $1.374 million. His ETH short position stands at 38,465.22 ETH, with an average entry price of $2,248.74, currently generating a floating profit of $2.018 million. The net floating profit across both positions is approximately $644,000.

Analyst: Bitcoin’s Key “Value Zone” Emerges—Current Volatility May Present a Cycle-Level Entry Opportunity

Crypto analyst Ali published a detailed analysis on X, arguing that rather than debating whether Bitcoin has hit its bottom, market participants should focus on whether the current volatility represents a “generation-defining entry opportunity.” Based on long-term trend lines, on-chain liquidity, and cost distribution metrics, Ali delineates the core “value range” for this cycle. On the support side, the UTXO Realized Price Distribution (URPD) shows a significant concentration of coins in the $63,111–$70,685 range, forming the current primary support zone; if price breaks below $63,111, the market may enter a liquidity vacuum. From a long-term perspective, Bitcoin is approaching the key upward trend line from the past decade (approximately $56,000–$60,000), a level historically associated with accumulation phases preceding major rallies.

Bitcoin call options with a $80,000 strike price exceed $1.6 billion in open interest, as market participants bet on a confluence of price reversal and rate-cut expectations.

According to CoinDesk, as market sentiment improves, the Bitcoin options market is undergoing a notable shift: the $80,000 call option on Deribit has become the most actively traded, with open interest exceeding $1.6 billion—surpassing the previously dominant $60,000 put option (which held approximately $1.41 billion in open interest). Analysts suggest that the recent temporary ceasefire between the U.S. and Iran has driven oil prices lower, easing inflation expectations and potentially strengthening market anticipation of Federal Reserve rate cuts—thereby benefiting risk assets including Bitcoin. Additionally, asset management firm 21Shares stated that, against the backdrop of sustained ETF inflows and rising institutional holdings, Bitcoin could potentially reach $100,000 by the end of Q2—if geopolitical tensions ease further and the regulatory environment improves. However, risks remain: the current ceasefire is fragile, and any escalation in Middle Eastern conflict could trigger a rebound in oil prices, dampening market risk appetite and thereby capping Bitcoin’s upside potential.

Chainalysis: Predicts Stablecoin Transaction Volume Could Exceed $15 Trillion by 2035, Surpassing Global Cross-Border Payment Volume

According to Cointelegraph, blockchain analytics firm Chainalysis released a report stating that stablecoin-adjusted transaction volume is projected to reach $719 trillion by 2035—marking a substantial increase from $28 trillion in 2025. If two major macro catalysts align, this figure could double further to $15 trillion, surpassing the current annual global cross-border payment volume of approximately $10 trillion. The two catalysts are: (1) the transfer of over $100 trillion in wealth from the Baby Boomer generation to younger, crypto-native generations; and (2) stablecoins fully replacing traditional payment rails as the default payment infrastructure. Rachael Lucas, an analyst at Australian crypto exchange BTC Markets, noted that strategic moves—including Stripe’s acquisition of Bridge and Mastercard’s partnership with BVNK—are concrete steps forward. Coupled with regulatory clarity provided by the GENIUS Act, institutional participation is expected to expand significantly.
