Tin tức từ ChainCatcher, nghiên cứu mới nhất của Trung tâm Nghiên cứu Tài chính Thay thế Cambridge (Cambridge Centre for Alternative Finance) cho thấy, khoảng 31% hoạt động của các nút Ethereum nằm ở Hoa Kỳ, khoảng 39% còn lại phân bố ở khu vực EU không bao gồm Vương quốc Anh, cho thấy sự phân bố địa lý của các nút Ethereum vẫn tập trung chủ yếu ở các quốc gia phương Tây. Người phụ trách nghiên cứu Alexander Neumuller cho biết, hiện tại sự phân bố các nút không tập trung ở một quốc gia duy nhất, mà chủ yếu phụ thuộc vào một số nhà cung cấp dịch vụ đám mây, bao gồm Hetzner, Amazon AWS và OVH.Điều đáng chú ý là, mạng Ethereum không cần phải có một nửa số người xác thực bị lỗi mới xảy ra vấn đề, khi hơn một phần ba số người xác thực cùng ngoại tuyến, mạng có thể không hoàn thành xác nhận cuối cùng của điểm kiểm tra khối (finalization). Neumuller chỉ ra rằng, các nút và người xác thực không phải là mối quan hệ một-một, một nút đơn lẻ có thể chạy nhiều người xác thực, do đó hiện tại không thể xác định chính xác ảnh hưởng thực tế của sự cố tại một nút hoặc nhà cung cấp đến mạng xác thực. Ngoài ra, nghiên cứu cũng đã đánh giá lại tình hình tiêu thụ năng lượng sau khi hợp nhất Ethereum (The Merge). Dữ liệu cho thấy, tiêu thụ năng lượng hàng năm hiện tại của Ethereum khoảng 7.9 GWh, tương đương với khoảng 1 megawatt công suất liên tục, chỉ bằng khoảng 0.02% mức trước khi hợp nhất, giảm khoảng 99.98% tiêu thụ năng lượng. Hiện tại, tỷ lệ năng lượng bền vững được sử dụng trong mạng Ethereum vượt quá 56%, cao hơn mức trung bình toàn cầu. Nghiên cứu cũng chỉ ra rằng, độ tập trung của phần mềm khách hàng cũng là một trong những rủi ro tiềm ẩn, nếu phần mềm khách hàng chiếm ưu thế xuất hiện lỗ hổng, có thể ảnh hưởng đến một lượng lớn người tham gia mạng. Báo cáo này được phát hành bởi Trung tâm Nghiên cứu Tài chính Thay thế Cambridge, được hỗ trợ bởi Quỹ Ethereum.

Theo thông tin từ ChainCatcher, báo cáo của The Block cho biết, báo cáo mới nhất từ Trung tâm Nghiên cứu Tài chính Thay thế Cambridge (CCAF) mang tên "Ethereum Hợp nhất" cho thấy khoảng 31% hoạt động của các nút Ethereum nằm ở Mỹ, 39% phân bố ở Liên minh Châu Âu (không bao gồm Vương quốc Anh), tổng thể cho thấy một mô hình tập trung ở phương Tây.Báo cáo chỉ ra rằng mạng lưới Ethereum có nguy cơ tập trung tiềm ẩn - các nút tập trung cao vào ba nhà cung cấp dịch vụ lưu trữ lớn là Hetzner, AWS và OVH, nếu hơn một phần ba các xác thực viên cùng ngắt kết nối, các điểm kiểm tra của mạng sẽ ngừng xác nhận cuối cùng (Finalization).Ngoài ra, báo cáo cũng đã tính toán lại mức tiêu thụ năng lượng của Ethereum, sau khi hợp nhất, lượng điện tiêu thụ hàng năm khoảng 7.9 gigawatt giờ, giảm khoảng 99.98% so với trước khi hợp nhất, tỷ lệ năng lượng bền vững chiếm hơn 56%, chi phí cần thiết để bù đắp lượng khí thải carbon hàng năm chỉ khoảng từ 33,500 đến 73,800 đô la Mỹ.

According to CoinDesk, the Cambridge Centre for Alternative Finance has released a longitudinal study on the resilience of Bitcoin's network physical infrastructure, covering 11 years of peer-to-peer network data and 68 verified submarine cable failure events.The study shows that 72% to 92% of global multinational submarine cables need to fail simultaneously for significant node disconnections to occur in the Bitcoin network. Based on 1,000 Monte Carlo simulations for each scenario, over 87% of real failure events had less than a 5% impact on nodes, and the correlation coefficient between cable failures and Bitcoin prices is close to zero (-0.02). The study also reveals a significant asymmetry between random failures and directed attacks: if an attacker targets key hub cables, the destruction threshold will drop sharply to 20%; if directed attacks target the five largest hosting service providers—Hetzner, OVH, Comcast, Amazon, and Google Cloud—removing just 5% of routing capacity could cause a similar impact.

The UAE Ministry of Finance and the Dubai Department of Finance announced that the first transaction has been completed in the pilot phase of the Digital Dirham central bank digital currency, marking the first significant progress since the project's launch.The transaction was executed through the government payment platform mBridge, signifying a key step for the UAE in applying national digital currency to government and private sector operations. Ahmed Ali Meftah, Executive Director of Central Accounting at the Dubai Department of Finance, stated that this transaction aims to test the technical integration and operational readiness of the central bank system, taking less than two minutes for the entire process, validating the potential of the Digital Dirham in enhancing settlement efficiency and shortening intergovernmental payment cycles.According to a policy document released by the Central Bank of the UAE in July, the issuance of the Digital Dirham will be phased, initially only for payment purposes, avoiding competition with savings or interest-bearing products. The project is seen as an important initiative by the Central Bank of the UAE to address the evolution of the monetary system in the digital economy era.According to the Atlantic Council, currently, only Nigeria, the Bahamas, and Jamaica have officially issued CBDCs, while 49 other countries are in the pilot phase.

ChainCatcher news, a new analysis released by the Cambridge Centre for Alternative Finance shows that the governance power of decentralized autonomous organizations (DAOs) behind DeFi protocols is highly concentrated, with a level of concentration comparable to the world's most unequal countries.By applying the Gini coefficient, the analysis found that the Gini coefficients of the top ten DAOs range from 0.97 to 0.99, indicating a high degree of power concentration. In contrast, South Africa's Gini coefficient is 0.63.The analysis reveals that although DAOs claim to be decentralized, in reality, most decisions are still dominated by a small number of large token holders. The Cambridge team stated that they will further refine the data in the future to analyze the concentration of power within DAOs.
