According to MSX.COM data, following the unexpected 23,000 decrease in US non-farm payrolls in July, the pre-market gains in the US optical communications sector further expanded. Coherent rose over 7%, Corning and Lumentum rose over 5%, and Marvell Technology and Credo rose over 4%. The storage sector also generally rose pre-market, with Micron Technology up 3.76%, SK Hynix up 1.16%, SanDisk up 5.31%, Western Digital up 3.64%, and Seagate Technology up 3.04%.

According to Gate.com, spot gold rose 3% to $4,368.18 per ounce, its highest level since June 17, according to Odaily Planet Daily. U.S. nonfarm payrolls fell by 23,000 in July, compared to market expectations of an 80,000 increase and a previous reading of 57,000.

Odaily Planet Daily reports that Starknet has announced the completion of a quantum-resistant signature transaction test. A wallet account using a quantum-resistant signature mechanism successfully completed a real transaction on the Starknet mainnet, with a transaction fee of approximately 6 cents, and the transaction can be verified through a block explorer. This account is currently an experimental, unaudited version, primarily used for research and testing. StarkWare stated that this transaction benefited from Starknet's account model design. Unlike most blockchains that fix the signature algorithm at the protocol layer, each Starknet account is a smart contract, capable of defining its own accepted signature schemes. Therefore, users can upgrade their wallets from traditional elliptic curve signatures to quantum-resistant signatures without hard forks, asset migrations, or address changes. StarkWare points out that most blockchains face the risk of quantum computing because wallet signatures and underlying verification systems rely on elliptic curve cryptography. Once large-scale quantum computers become available, running Shor's algorithm could potentially break these encryption systems. Currently, the Starknet ecosystem supports quantum-resistant signature schemes based on Falcon-512, which are part of the NIST post-quantum cryptography standardization framework. The implementation of these schemes has been promoted by the ecosystem team and organizations such as OpenZeppelin.

Odaily Planet Daily reports that U.S. employers unexpectedly cut jobs in July, and data from previous months was revised significantly downward, indicating that the labor market is facing challenges after an unexpectedly strong performance earlier this year. Data released Friday by the U.S. Bureau of Labor Statistics showed that nonfarm payrolls fell by 23,000 in July, following significant downward revisions to the employment figures for the previous two months. The unemployment rate fell to 4.1%, while the labor force participation rate continued to decline. The report suggests that the U.S. labor market may be beginning to weaken amid rising prices and increased uncertainty stemming from the Iran war. However, strong consumer demand has so far encouraged some employers to continue their hiring plans. This data may also prompt the Federal Reserve to postpone interest rate hikes, as policymakers weigh inflationary pressures against employment risks.
