Odaily Planet Daily News: Recently, one of the world's authoritative academic journals, Science, published an e-letter online: "Limitations of a study on the network of developers and correlated returns of cryptocurrencies". This is the first e-letter article in the blockchain field published in Science magazine. This e-letter was published by Xueyan.Tang, chief scientist of Salus. Salus is a blockchain security company based on scientific research, aiming to solve some of the most complex security problems in the industry. This article mainly provides peer review comments on the research paper "From code to market: Network of developers and correlated returns of cryptocurrencies" published in Science Advances: "The blockchain industry as a whole cannot ignore the potential impact of cryptocurrencies with lower market capitalization on the market and cannot rely solely on GitHub platform activities as a measure of developer project participation. The study provides insights into the correlation between cryptocurrencies, but does not study the factors that drive the market value of cryptocurrencies. Finance, as an important part of the blockchain industry, should be considered when studying. It is also very important to continue to explore other factors that may affect the market value of cryptocurrencies." Salus Chief Scientist Xueyan.Tang said, "As an interdisciplinary industry, the blockchain industry has been favored by a lot of capital and developers in recent years, and has a tendency to evolve into an independent discipline. This e-letter is an important signal that top journals are beginning to pay attention to the review opinions of blockchain professionals. I call on more researchers to try to publish positive research results related to blockchain in top journals and on journal covers. This is crucial to the construction of the blockchain discipline and will also bring significant changes to the traditional industry's views on the blockchain industry." After the publication of the e-Letter, Science published their second research article on blockchain, "Robot swarms neutralize harmful Byzantine robots using a blockchain-based token economy”, the article was written by Volker Strobel et al. Note: Science eLetters is an electronic version, mainly publishing commentary articles selected by Science editors on papers published in Science magazine in the past three months.
