The demand for blockchain talents has surged in recent years, and there is a pressing need to understand what core skills and essential qualifications the blockchain talents demand and how employers value them in recruitment. This paper aims to reveal the crucial facts and patterns regarding the status quo of the recruitment market for blockchain-related jobs in China and clarify the heterogeneous nature of professionals demanded by blockchain-related jobs. We propose a data-driven approach by combining descriptive statistics, topic modeling, and regression analysis based on large-scale job posting data collected from a nationwide Chinese recruitment website. By this approach, we provide an overall picture of the landscape of the recruitment market for blockchain-related jobs and identify 11 skill sets that are most in-demand for blockchain-related jobs. On this basis, the skill sets of Blockchain Development and Cryptocurrency have emerged to be the most valued ones that affect salary levels: the talents mastering these two skill sets can obtain 21.4%, 10.4% higher average salaries, respectively, than those without these skills. The analyses also provide evidence that employers could attach importance to job candidates with T-shaped characteristics. Drawing on the findings, we also provide implications for blockchain practitioners.
