Ukraine Considers Establishing Strategic Bitcoin Reserve
The Ukrainian government is preparing legislation to establish a national strategic Bitcoin reserve. It is reported that Ukraine currently holds about 46,351 BTC, worth about $4.8 billion. These bitcoins mainly come from donations, asset seizures and fundraising activities during the war. Ukrainian MP Yaroslav Zhelezniak said that the relevant bill has entered the final drafting stage and is expected to be submitted to parliament for deliberation soon. The bill aims to formally incorporate Bitcoin into the country's fiscal strategy.
Previously, the Ukrainian parliament passed a virtual asset bill, but it was withdrawn under pressure from the presidential office and the National Securities Committee. Currently, the National Securities Committee has proposed 80 amendments to improve the legal framework for crypto assets. Ukraine's move marks its increasing emphasis on cryptocurrencies in its national financial strategy.

Ethereum Foundation announces the launch of the "Trillion Dollar Security Initiative"
The Ethereum Foundation announced the launch of the "Trillion Dollar Security Initiative" on May 14, 2025, aiming to comprehensively improve the security performance of the Ethereum ecosystem to the level of supporting global economic infrastructure. The plan will conduct a comprehensive assessment of the security status of all levels of the Ethereum technology stack, implement key improvements, and strengthen security communication. The project is led by Fredrik Svantes and Josh Stark, and is supported by three experts in the field of blockchain security. The Ethereum Foundation also calls on community members to provide feedback through designated channels and participate in this security upgrade plan. 1confirmation founder: optimistic about the long-term value of L2 to Ethereum 1confirmation founder Nick Tomaino posted on social media to emphasize the positive impact of L2 solutions on Ethereum (ETH), pointing out that the application chain provides developers with autonomy while also bringing value to Ethereum. He said that L2 has multiple benefits: distributing ETH, expanding the EVM developer network effect, and burning ETH through activities, and said that "most people still believe in the false narrative that L2 success is detrimental to ETH."
Ethereum Fusaka upgrade plans to introduce PeerDAS to reduce L2 and validator costs
Following the successful deployment of the Pectra upgrade, Ethereum core developers have turned their attention to the next major upgrade "Fusaka", which is scheduled to go online at the end of 2025. It has been determined that proposals involving PeerDAS will be included to reduce the operating costs of Layer 2 expansion solutions and validators. PeerDAS (Peer-to-Peer Data Availability Sampling) is a data availability sampling mechanism that allows nodes to verify their availability without downloading the full data, thereby improving network efficiency and reducing resource consumption. This mechanism is expected to further optimize Ethereum's expansion capabilities and enhance the scalability and decentralization of the network. It is reported that the specific content of the Fusaka upgrade is still under discussion, but developers have reached a consensus on the introduction of PeerDAS.
Xiao Feng: Ethereum Foundation should not stay away from the Chinese market, and it is recommended to set up an office in Hong Kong
According to the ThreeDAO official account of Wanwudao, Xiao Feng, the founder of Wanxiang Blockchain, suggested that the Ethereum Foundation set up an office in Hong Kong in a private communication with Vitalik.
Xiao Feng pointed out that blockchain developers are mainly concentrated in the English and Chinese worlds, and losing the Chinese market means losing important global developer resources. Vitalik said that the development force of the Ethereum Foundation in Berlin is mainly engaged in underlying technology work, and the underlying technology of Ethereum has matured, leaving only room for optimization.
Xiao Feng said that he once said to Vitalik half-jokingly: "We have the 11th Blockchain Conference in Shanghai in October. If you come and get arrested, I will go to jail with you." He then pointed out that this was just a joke, and said that in fact, China's technical departments, government agencies and developer groups respect Ethereum technology and suggest that the foundation should not stay away from the Chinese market.
Ethereum co-founder: Ethereum is an alternative to Bitcoin, not a competitor
At the Consensus 2025 conference, Ethereum co-founder Anthony Di Iorio said that Ethereum "is not intended to be a competitor to Bitcoin, but to be an alternative."

Di Iorio initially entered the encryption field by advocating Bitcoin and met Vitalik Buterin when he hosted a Bitcoin party in Toronto in 2012. He stressed: "Ethereum has the potential to eventually surpass Bitcoin in market capitalization... With the number of use cases and the value that Ethereum can create, I think it has such a chance."
