 Ethereum co-founder Vitalik Buterin stated that artificial intelligence is expected to accelerate the development roadmap of the network while enhancing security standards.

In response to an experiment, someone completed the entire Ethereum 2030 roadmap coding within weeks using a method called "vibe coding." Buterin wrote: "Six months ago, this was even beyond the realm of possibility, and what really matters is the direction in which the trend is moving."

Buterin also personally tested AI programming capabilities; he used a laptop to build a system equivalent to his own blog software within an hour.

The Ethereum founder suggested using half of the speed improvement brought by AI to strengthen security, such as adding more test cases, conducting formal verification, and implementing multiple client implementations.

He stated: "People should remain open to such a possibility (not certainty, but possibility): the completion speed of the Ethereum roadmap may far exceed people's expectations, and the security standards will also be much higher than expected."

 according to DLNews, the Russian central bank warns that the country's financial pyramid scheme organizers have largely shifted to using cryptocurrencies. In 2025, Russian citizens sent funds to cryptocurrency wallets held by fraudsters, involving more than 4,600 wallet addresses.

The central bank discovered 7,087 financial pyramid schemes, fake brokers, and other fraud plans last year, with 80% operating online, most using cryptocurrencies and money mules to transfer funds. In 2025, 84% of fraudsters used cryptocurrencies to raise funds, higher than 77% in 2024. The Russian central bank has ordered the blocking of 21,500 related websites and social media posts.

The central bank pointed out that fraudsters choose cryptocurrencies to remain anonymous and evade punishment, and pledged to strengthen monitoring and intensify the crackdown on crypto fraud.

 according to The New York Times, President Trump stated in an interview that if necessary, the U.S. military plans to continue attacks on Iran for "four to five weeks," and insisted that Israel and the United States "will have no difficulty" maintaining the intensity of the fighting. At the same time, he also warned that there could be more casualties for the U.S. military. When asked about a power transition plan, Mr. Trump said he hopes that Iran's elite forces (including senior officers of the Islamic Revolutionary Guard Corps who have great influence in the current regime and benefit from it) can hand over weapons to the Iranian people. In a call lasting about six minutes, Trump also said he has three "very good" candidates to lead Iran, but he refused to disclose specific names. He repeatedly referred to his experience in Venezuela, which may imply that he believes the approach that worked in Venezuela could also be applied to Iran. He also said that if the new leadership in Iran shows a pragmatic and cooperative attitude, he is willing to lift sanctions on Iran. However, he also refused to specify how (or whether) his administration would defend the Iranian people, whom he said should overthrow the current government. (Jin10)

over the past weekend, due to the closure of traditional global financial markets, a large amount of capital flowed into prediction markets such as Polymarket and Kalshi, as well as decentralized exchanges like Hyperliquid. Investors attempted to hedge risks or speculate on the aftermath of the US and Israel's attacks on Iran through these platforms.

As tensions continued to rise before the airstrikes, keen traders began heavily betting on the direction of the Middle East conflict. Among them, prediction contracts highly related to geopolitics, such as "Will Iran's Supreme Leader Khamenei step down soon?" were highly sought after and strongly promoted by the two major mainstream prediction platforms Kalshi and Polymarket.

However, this capital frenzy quickly turned into a public opinion storm. Last Saturday, a large number of doubts began to emerge on the social platform X, accusing some insiders of profiting massively on prediction markets by using advance knowledge of the military strike. Previously, similar accusations had appeared in the financial circle when the US military struck Venezuela and forcibly took control of Maduro.

These alleged "war profiteering" actions have triggered strong outrage in the US political circle. Democratic Congressman Mike Levin exposed on social media that a Polymarket account named "Magamyman" earned $515,000 in a single day just by betting that the US would strike Iran.

"This behavior being legal is absolutely ridiculous. People around Trump are lining their pockets with war and death, and I will soon propose legislation to completely ban such trades," Connecticut Senator Chris Murphy angrily responded to these accusations.

Arizona Senator Ruben Gallego also strongly condemned this phenomenon: "This is blatant insider trading and must be classified as illegal. These scoundrels are profiting from our fallen soldiers, and their actions are both disgusting and utterly immoral." It is reported that the US military announced last Sunday that since the start of the strike, three US soldiers have died and five have been seriously injured.
