E^2 C-Chain: A Two-Stage Incentive Education Employment and Skill Certification Blockchain

Abstract

Employment and workforce industry become more important because the human capital value is linked to the company's profitability. Company becomes employee-centric in the 21st century. To hire an appropriate employee, and reduce hiring liability workplace violence, background screening marketing growth quickly. However, in the human resource industry, background check still is a pain point, especially for employment, education, and skill verification. The traditional background check is prolonged and inaccurate. For overseas recruitment, background check will be more troublesome. This paper comprehensively addresses the challenge of the education, employment and skill verification problem. We propose an innovation E^2 C-Chain which is a two-stage blockchain based education, employment and skill certification system. In the first stage, the new blocks are created when a trust organization verifies the education and employment information of the employee. In the second stage, to encourage the verifiers to participate in the skill verification process, we employ a Vickrey-Clarke-Groves (VCG) game based incentive mechanism to find the Nash Equilibrium and ensure social cost minimization. We also present the theoretical proofs and extensive simulations to demonstrate beneficial properties and efficiency of our proposed system.
