Zcash fixes critical vulnerability: previously threatened the security of over 25,000 ZEC, worth approximately 6.5 million dollars

The privacy coin Zcash recently disclosed and fixed a critical security vulnerability that could have been exploited by malicious miners to transfer over 25,000 ZEC (approximately 6.5 million USD) from the deprecated Sprout privacy pool. Security researcher Alex "Scalar" Sol disclosed on March 23 that the vulnerability stemmed from the zcashd node skipping proof verification when processing transactions involving the Sprout pool.The official statement indicated that the vulnerability had existed since July 2020 but had not been actively exploited, and user funds remained safe at all times. The development team has released version 6.12.0 to complete the fix, and mainstream mining pools have completed the upgrade deployment within a few days. Additionally, the unaffected Zebra full node implementation has the capability to trigger a chain fork, providing extra protection in the event of exploitation.It was disclosed that although the Sprout pool closed to new deposits in November 2020, approximately 25,424 ZEC remained untransferred. Even if the vulnerability were exploited, Zcash's "turnstile" mechanism would prevent inflationary issuance, ensuring that the total supply would not be breached. This vulnerability was discovered with the assistance of AI, and the researcher will receive a total bounty of 200 ZEC (approximately 51,000 USD). It is worth noting that this is not the first time Zcash has encountered a significant vulnerability; as early as 2019, it had fixed a serious flaw that could lead to unlimited issuance.

Analysis: Ethereum is at a critical moment of success or failure in a high-risk balancing strategy

According to CoinDesk analysis, as the pressures from scalability challenges, quantum technology, and artificial intelligence continue to grow, Ethereum is at a critical juncture in high-risk balancing strategies. In the first three months of 2026, the Ethereum ecosystem faces multiple structural pressures. Vitalik Buterin sharply criticized the Layer2 scaling path at the beginning of the year, pointing out that many Rollup designs rely on centralized components and isolated environments, failing to truly inherit the security guarantees of the mainnet, leading to ecosystem fragmentation and inconsistent security assumptions.Meanwhile, the Ethereum Foundation has incorporated the threat of quantum computing into its recent planning, advancing research on LeanVM and post-quantum signature schemes. Internally, Tomasz Stańczak, the co-executive director of the Ethereum Foundation, has left after about a year in office, a change seen as a signal of the foundation's internal realignment of priorities. Additionally, the foundation is accelerating its layout for decentralized AI research, attempting to position Ethereum as the "trust layer" for AI systems, used for verifying outputs, coordinating agents, and supporting machine-to-machine economic activities.Overall, Ethereum can no longer handle these issues in isolation; they are interwoven. The network is being pulled in multiple directions simultaneously, making it increasingly difficult to maintain balance. Unlike previous cycles, the current predicament is more about structure than short-term momentum. The short-term focus remains on mainnet scaling, with the planned Glamsterdam upgrade set to be a litmus test to determine whether the Ethereum network can successfully transform into a robust, quantum-resistant "trust layer" supporting the global AI economy.

The negotiations for the "Clarity Act" have entered a critical window period, with deep involvement from the White House becoming a unique variable

Kristin Smith, president of the Solana Policy Institute, recently shared her views on the legislative progress of the Clarity Act. She stated that although the bill faces resistance due to the withdrawal of support from Coinbase CEO Brian Armstrong and controversies in the banking sector, its complexity determines the long-term nature of the legislative process. Current negotiations exhibit two new characteristics: first, senior officials from the White House are directly involved, with presidential aides like David Sacks pushing for dispute resolution; second, traditional financial institutions are participating in negotiations for the first time.If the Senate Banking Committee can complete its review of the bill by March or April, there is hope to advance the legislation before the July recess; otherwise, the next window will not open until the fall. Smith, who previously led the Blockchain Association and spearheaded the passage of the Genius Act, believes that despite facing opposition from figures like Elizabeth Warren, the support from key Democrats such as Chuck Schumer and the ongoing pressure from President Trump are changing the odds of the bill's passage. On Wednesday, after Trump urged the banking sector to make concessions in a post on Truth Social, expectations in the market for the passage of cryptocurrency legislation within the year have noticeably increased.
