Ukraine considers establishing a 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 approximately $4.8 billion. These Bitcoins primarily come from donations during the war, asset seizures, and fundraising activities. Ukrainian parliamentarian Yaroslav Zhelezniak stated that the relevant bill has entered the final drafting stage and is expected to be submitted to parliament for review soon. The bill aims to formally incorporate Bitcoin into the national financial strategy. Previously, the Ukrainian parliament passed a virtual asset bill, but it was withdrawn under pressure from the presidential office and the national securities commission. Currently, the national securities commission has proposed 80 amendments to improve the legal framework for crypto assets. This move by Ukraine marks an increasing emphasis on cryptocurrencies within its national financial strategy.

1confirmation founder: optimistic about L2's long-term value for Ethereum.
Nick Tomaino, founder of 1confirmation, emphasized the positive impact of L2 solutions on Ethereum (ETH) in a social media post, pointing out that application chains provide autonomy for developers while bringing value to Ethereum. He stated that L2 has multiple benefits: distributing ETH, expanding the EVM developer network effect, and burning ETH through activities, and noted that 'most people still believe the false narrative that L2 success is detrimental to ETH.'
The Ethereum Fusaka upgrade is set to introduce PeerDAS, aimed at reducing costs for L2 and validators.
Following the successful deployment of the Pectra upgrade, Ethereum core developers have shifted their attention to the next major upgrade, 'Fusaka,' planned for the end of 2025. It has been confirmed that proposals involving PeerDAS will be included, aimed at reducing operational costs for Layer 2 scaling solutions and validators. PeerDAS (Peer-to-Peer Data Availability Sampling) is a data availability sampling mechanism that allows nodes to verify availability without requiring complete data downloads, thereby improving network efficiency and reducing resource consumption. This mechanism is expected to further optimize Ethereum's scaling capabilities, enhancing the network's scalability and decentralization features. It is reported that the specific details of the Fusaka upgrade are still under discussion, but developers have reached a consensus on introducing PeerDAS.
Xiao Feng: The Ethereum Foundation should not distance itself from the Chinese market and suggests establishing an office in Hong Kong.
According to news from Wanwu Island's ThreeDAO public account, Wangjiao Blockchain founder Xiao Feng suggested to Vitalik in a private conversation that the Ethereum Foundation should establish an office in Hong Kong. Xiao pointed out that blockchain developers are mainly concentrated in the English and Chinese-speaking worlds, and losing the Chinese market means losing important global developer resources. Vitalik indicated that the development force of the Ethereum Foundation in Berlin mainly focuses on underlying technology work, and that the underlying technology of Ethereum has matured, leaving only room for optimization. Xiao Feng humorously said to Vitalik, 'We have the 11th Blockchain Conference in Shanghai in October. If you get caught when you come, I'll sit in jail with you.' He then clarified that this was just a joke, stating that in fact, China's technical departments, government agencies, and developer community have a respectful attitude toward Ethereum technology, suggesting that the foundation should not distance itself from the Chinese market.

Di Iorio initially entered the crypto space by advocating for Bitcoin and met Vitalik Buterin at a Bitcoin meetup in Toronto in 2012. He emphasized, 'Ethereum has the potential to eventually surpass Bitcoin in market capitalization... Given the number of use cases and the value Ethereum can create, I believe it has that opportunity.'
