A common issue faced by the HR department at a large company is how to identify a candidate with the right skills, work experience, and educational background. Often, the solution is to hire a professional recruiter or headhunter, who either identifies candidates via personal networking or through scanning social media sites such as LinkedIn. The fee paid to a recruiter is equal to a month's salary for the hired candidate or more. Blockchain can be utilized to build a decentralized database of professionals. This can serve two purposes. First, it provides transparency to match employers and candidates. Second, every company can learn the history of a potential employee and the person's current employment status. This can help to filter out potential fraudsters getting employed by a company.
