Solana releases quantum roadmap: selects Falcon solution, existing migration work is ready

Solana's official article on the potential impact of quantum computing on blockchain reiterates that the quantum threat is still years away, but the Solana ecosystem has already conducted thorough research and technical preparations in advance.The independent verification client development teams Anza and Firedancer (which together represent a large portion of the network's staking share) have unanimously concluded after independent research that a compact signature scheme suitable for high-throughput blockchains is needed, and they have jointly selected the Falcon scheme. Both parties have published their initial implementation code on GitHub.In addition, the Solana Winternitz Vault developed by Blueshift has been operational in the ecosystem for over two years, providing a direct quantum-resistant path. Earlier this year, Google Quantum AI listed this Vault as a leading example of forward-looking post-quantum work in its white paper.Solana's current quantum roadmap includes ongoing quantum research and evaluation of Falcon and alternative solutions; adopting post-quantum solutions for new wallets when quantum becomes a credible threat; and migrating existing wallets to the selected solution. The official statement indicates that the migration work is manageable and can be completed quickly when the time comes, with network performance expected to remain largely unaffected.

a16z releases global financial stack report: stablecoins are reshaping the financial system

a16z crypto released an analysis report titled "The New Stack of Global Finance: The Stablecoin Edition." The report points out that stablecoins have evolved from niche trading tools into fundamental financial pipelines, giving rise to a new type of "banking as a service" model that is driving the reconstruction of the financial system. The report believes that the transition to on-chain finance has "crossed the point of no return."The report categorizes blockchains into three types: general-purpose chains (such as Solana, Ethereum, and L2), payment-specific chains (such as Stripe's Tempo), and institutional networks (such as Canton). It also notes that the bottlenecks in the banking industry are easing, with a number of crypto-friendly banks actively connecting on-chain infrastructure with traditional fiat systems. The competition for stablecoin issuance has shifted to regulatory positioning, with issuers vying to obtain OCC national trust charters.The report states that payments are the "first act," while credit may be the more important "second act." The large-scale issuance of stablecoins will give rise to a new on-chain credit market, allowing capital to form outside the traditional banking system. The report also emphasizes that stablecoins not only enhance the dominance of the dollar but also provide emerging market users with access channels to the dollar.

BitMine increased its holdings by 101,901 ETH last week, bringing the total holdings to approximately 5.078 million coins

According to PR Newswire, BitMine increased its holdings by 101,901 Ethereum last week, marking the highest weekly purchase volume since the week of December 15, 2025. As of April 26, 2026, its total Ethereum holdings reached 5,078,386, accounting for approximately 4.21% of the total Ethereum supply.Currently, the total value of the cryptocurrencies, cash, and other investment assets held by BitMine is approximately $13.3 billion, which includes $940 million in cash, 200 Bitcoins, $200 million in equity assets from Beast Industries, and a $91 million investment in Eightco Holdings (ORBS). Additionally, it has staked 3,701,589 Ethereum (73% of total holdings), valued at approximately $8.8 billion, with a current annualized staking yield of about $264 million.BitMine Chairman Tom Lee stated that the company's ETH holdings surpassed 5 million this week, achieving this accumulation in just 10 months, and has completed 84% of its goal to hold 5% of the total ETH supply. Tom Lee noted that multiple research reports suggest ETH is gradually becoming a "store of value" asset and will be used as collateral in digital asset financial transactions. Since the outbreak of the U.S.-Iran war, ETH has outperformed the S&P 500 by 1,696 basis points, making it one of the best-performing assets globally (second only to crude oil).He also pointed out that Ethereum continues to benefit from the dual drivers of Wall Street's on-chain tokenization and the growing demand for public neutral blockchains from AI intelligent systems, indicating that this round of the crypto winter has entered its final phase.

Spark releases Q1 2026 financial report: net agreement surplus of 3.46 million USD

The Spark protocol released its financial report for the first quarter of 2026 on April 27.The report shows that the gross protocol return for the quarter was $31.5 million (a 31% decrease quarter-over-quarter), the net protocol return was $6.91 million (a 30% decrease quarter-over-quarter), and the net protocol surplus was $3.46 million (a 47% decrease quarter-over-quarter).

Additionally, Spark launched a SPK token buyback program, investing $986,000 to repurchase tokens from the open market.The revenue structure for this quarter has shifted, with distribution rewards becoming the largest net return contributor to the protocol ($3.31 million), surpassing the net income from Spark Liquidity Layer (SLL) for the first time. The average deployed capital for SLL was $1.93 billion, with an average annualized yield of 5.8%. SparkLend continues to support institutional-level lending operations, with its USDT savings treasury continuing to grow. The Spark institutional lending product deployed $150 million at the end of the quarter, with governance approving its $1 billion cap.The report noted that the current unfavorable conditions in the DeFi lending market have led to a narrowing of the SLL interest margin, but the protocol's distribution business has seen significant growth. USDS, as a scalable savings-based return mechanism in a poor market environment, is continuously expanding its distribution channels to multi-chain and various stablecoins.
