ChainCatcher news, according to a report from Coindesk, security firm Hexens' white-hat hackers discovered a vulnerability in the Aptos blockchain, which has now been fixed. If maliciously exploited, this vulnerability could have exposed up to 70 billion US dollars worth of digital assets to systemic risk, including stablecoins and cross-chain bridges. In late February, Hexens researchers reported a critical vulnerability in the Move virtual machine (the execution environment for on-chain smart contracts) to the Aptos development team. It was identified as a "stale cache vulnerability," which could cause a type confusion bug, meaning the software could be tricked into mistaking one on-chain resource for another. The researchers simulated this attack in a real network environment, achieving a success rate of over 90%. They used a well-configured set of servers (costing only 3,000 US dollars) to simulate about one-third of the validator network, and the attack did not require insider access or special privileges. The Aptos team fixed the vulnerability immediately after it was discovered, with no loss of funds occurring.

BlockBeats News, July 5th​—The U.S. Department of the Treasury announced today that, on the occasion of the 250th anniversary of the United States, it has officially launched the "Trump Accounts" nationwide. The U.S. Department of the Treasury stated that this is an innovative savings and investment platform designed to ensure that future generations of Americans have a stake in the U.S. economy from day one. The "Trump Accounts" will help families build long-term financial security while deepening their understanding of how the U.S. capital markets operate. The "Trump Child Investment Account" is expected to inject $30-50 billion of incremental funds directly into the U.S. stock market in the first year. Subsequently, families and employers can contribute up to $5,000 per account annually, leading to a continuous inflow of several billion dollars or more in stable funds over the long term, providing long-term buying support.
