Skillchain is a blockchain based skill verification platform, where everyone has the opportunity to create their own 'career skill passport'. In this platform, all higher education diplomas, work qualifications, recommendation letters, professional skills, and courses taken by individual users will be stored on the chain, clear and transparent. Enterprise users can achieve efficient and transparent recruitment processes. In the past, recruiters were inundated with thousands of resumes every day, unable to verify them one by one, time-consuming and labor-intensive, and without any guarantee. Nowadays, every resume is strictly controlled by Skillchain to ensure that the company finds the best candidate on the platform.SKI is a functional token of the Skillchain platform and also an ERC-20 standard token. Enterprises can use SKI tokens to purchase platform services, optimize the recruitment process, and browse the search dynamics of all platform users across the entire line. For talents selected by enterprises, the platform will screen based on the number of tokens obtained by users. In addition, users can use SKI tokens to purchase special features to enhance their profile, and they can also purchase educational products through tokens. Owners of 'career skills passports' can purchase more features to make it easier for recruitment companies to find their profiles....
