optimistic

Optimistic is an Ethereum scaling solution that belongs to the optimistic Rollup technology. It increases transaction throughput and reduces fees by bundling a large number of transactions into a single batch and verifying them on the Ethereum mainnet. Optimistic Rollup assumes that transactions are valid by default and only performs computation-intensive rollback verification when fraud is detected. Its design aims to maintain the security and decentralization of Ethereum while significantly enhancing the network's scalability, making it an important component of Ethereum Layer 2 solutions.

first_img Blockstream executive Peter Bain: Institutional clients are optimistic about the Bitcoin bull market

Blockstream Chief Marketing Officer Peter Bain stated in a recent interview that Bitcoin has maintained the $81,000 mark amid stock market sell-offs, rising 10-year U.S. Treasury yields, and turmoil in Europe, which he described as "a very, very strong signal." He made this statement during a conversation with Grace Remington and Sean Hagan.Bain emphasized that technological development precedes price and discussed topics such as adoption, stablecoins, and tokenized stocks. He introduced Blockstream's new center established in Lugano and a new consulting department aimed at institutional clients, while explaining why treasury companies are mainly concentrated in the United States and why Switzerland will become the next market—Switzerland's clear regulatory framework and strong banking foundation make it an ideal launch market.Regarding quantum computing, Bain believes that the related threats will take decades to materialize, and that Bitcoin's real weaknesses lie elsewhere. He referenced the PHP vulnerability incident, stating that the industry needs to rethink the way software is released, and introduced Blockstream's research on quantum-resistant signature solutions, how consensus can be reached for quantum upgrades, and the Bitcoin Security Alliance. Additionally, he provided the first update on the Liquid Network event progress: the exchange service has been restored, the network is back online, and users can transfer Bitcoin back to the main chain. Looking ahead to 2027, Bain stated that institutional clients believe Bitcoin "is expected to usher in a major bull market."

first_img Analyst: PCB prices are expected to rise again in the third quarter, optimistic about Taiguang Electric and Nandian's future market

According to the Economic Daily, in the past six months, CCL manufacturers have raised product prices by about 20% to 30% due to the overall increase in upstream material prices. Most PCB manufacturers have not been able to pass on these costs quickly enough, resulting in a time lag of 2 to 3 months, which has eroded profit margins. Institutional investors indicate that starting from the third quarter of this year, some PCB manufacturers will increase prices, and the benefits are expected to drive a rebound in the profitability of related manufacturers.Analysts state that in terms of substrates, electronic fiberglass cloth led by T glass and copper foil drilling needles are still in short supply, with T glass experiencing the most severe shortage, with some manufacturers facing a gap of up to 20%. This gap is expected to continue into next year. It is anticipated that in the second half of this year, substrate manufacturers will enter a supply-demand imbalance driven by the high demand for AI GPUs and ASIC high-performance computing, as well as the continued tightness of key raw materials. Substrate manufacturers will continue to adopt rolling price adjustments, with prices still having double-digit upward potential.Additionally, due to the sustained high demand related to AI and the specification upgrades driven by new generation products, there is continued optimism that CCL manufacturers will benefit from both price and volume increases. With raw material prices remaining tight and the delivery times for high-end CCL continuing to extend, the trend of price increases remains unchanged. There is continued optimism for the future development of Taiwanese CCL manufacturers such as Taiflex and Taisil. Meanwhile, as the substrate gap gradually widens, it benefits the bargaining power of substrate manufacturers, and the trend of price increases will continue, maintaining a positive outlook on the future performance of Taiwanese substrate manufacturers, including Nanya Technology and other supply chain partners.
