The core feature of the NU7 upgrade is to reduce the time interval between Zcash blocks from 75 seconds to 25 seconds. This change means that the time required to wait for three transaction confirmations will be shortened from nearly four minutes to about 75 seconds. This upgrade has been running on Zcash's test network and is awaiting final integration into the node software.In addition to improving speed, NU7 will also bring two important adjustments: first, 60% of the fees collected from each block will be removed from circulation, and these tokens will begin to be returned to miners around February 2031. Second, Zcash's original Sprout privacy system will be completely shut down, so all funds still held in that system must be transferred out before the upgrade is activated; otherwise, they will become unusable.

Polymarket's CEO Shayne Coplan stated during a fireside chat at the Token2049 conference in Singapore that cryptocurrency trading is evolving into a game of "irrational exuberance," where traders compete to be the first to find the next hundredfold token. He pointed out that people think they are buying something valuable, but in reality, it is worthless; however, as long as there is a possibility of it rising to 100 times, they want to sell before it goes to zero. Coplan mentioned that some traders can gain considerable wealth through this strategy, but it is essentially a game of "irrational exuberance and hot potato," where rising asset prices will eventually fall back.Coplan indicated that the continuous growth of Polymarket's user base shows that some traders are looking for betting opportunities with more predictable odds, rather than the next skyrocketing cryptocurrency. He explained that trading these markets on Polymarket does not have exponential upside potential, but informed traders will continue to place bets on future events with more predictable odds. According to data from DefiLlama, Polymarket is the second-largest prediction market, with a trading volume of $1.21 billion in the past seven days, while the largest market, Kalshi, had $2.3 billion.The growth of prediction markets has also attracted more attention from U.S. regulators. It was reported that JPMorgan terminated its banking relationship with Polymarket on August 14 due to regulatory concerns but expressed interest in acting as an underwriter if Polymarket seeks to go public.

Samsung Electronics has launched the passport-type foldable smartphone Galaxy Z Fold8 this year, and the supply of display driver chips (DDI) is tight. The demand for Z Fold8 has exceeded expectations, and Samsung is increasing component orders.
