论文摘要
技能验证是劳动力招聘的核心问题。公司和学术界经常面临确定申请人技能的困难，因为候选人所声称的技能的证书通常无法立即进行验证和昂贵的测试。文献中已经提出了区块链，以分散的方式进行技能验证和防篡改信息存储。但是，这些方法中的大多数都涉及存储传统大学在区块链上颁发的证书。在考虑认证程序本身的少数技术中，诸如（a）具有有限员工的可伸缩性，（b）在多个评估者上的成绩均匀性，或（c）通常不会从评估人员那里提取诚实的努力。我们提出了一个基于区块链的平台，名为SkillCheck，该平台考虑了上述问题，并确保了几个理想的属性。该平台激励通过付款与代币进行分级的努力，该代币从平台用户的付款中产生的代币，例如招聘人员和测试人员。我们提供了平台设计的详细说明以及该算法的可证明属性。
Skill verification is a central problem in workforce hiring. Companies and academia often face the difficulty of ascertaining the skills of an applicant since the certifications of the skills claimed by a candidate are generally not immediately verifiable and costly to test. Blockchains have been proposed in the literature for skill verification and tamper-proof information storage in a decentralized manner. However, most of these approaches deal with storing the certificates issued by traditional universities on the blockchain. Among the few techniques that consider the certification procedure itself, questions like (a) scalability with limited staff, (b) uniformity of grades over multiple evaluators, or (c) honest effort extraction from the evaluators are usually not addressed. We propose a blockchain-based platform named SkillCheck, which considers the questions above, and ensure several desirable properties. The platform incentivizes effort in grading via payments with tokens which it generates from the payments of the users of the platform, e.g., the recruiters and test-takers. We provide a detailed description of the design of the platform along with the provable properties of the algorithm.
