Communication costs per phase.

In recent years, the unemployment situation of teenagers has become increasingly serious, and many college students face the problem of unemployment upon graduation. Concurrently, Companies need more support in their talent acquisition processes, including high costs, security concerns, inefficiencies, and time-consuming sourcing procedures. Moreover, job applicants frequently confront risks associated with potentially compromising their personal information during the application process. Since blockchain technology has the characteristics of non-tampering, traceability, and non-repudiation, it has outstanding significance for solving the trust problem between organizations. Blockchain has emerged as a powerful tool for tackling talent acquisition campaigns. This study proposes a novel approach utilizing consortium chain technology in conjunction with the InterPlanetary File System (IPFS) to develop a decentralized talent recruitment system. This approach enables students, educational institutions, and potential employers to encrypt and upload data to the blockchain through consortium chain technology, with strict access controls requiring student authorization for resume data retrieval. The proposed system facilitates a symbiotic relationship between educational institutions and industry partners, allowing students to identify suitable employment opportunities while enabling companies to source candidates with requisite expertise efficiently. Finally, the system could meet the characteristic requirements of various blockchains, perform well in terms of communication cost, computing cost, throughput, and transaction delay in the blockchain, and contribute to solving talent recruitment.

近年来，青少年失业形势日趋严峻，诸多高校毕业生亦面临毕业即失业的困境。与此同时，企业在人才招聘流程中存在诸多痛点：招聘成本高昂、存在安全隐患、效率低下且人才寻访流程耗时冗长。此外，求职者在求职过程中时常面临个人信息泄露的风险。区块链技术具备不可篡改、可追溯、不可否认的特性，对于解决组织间的信任难题具有重要意义，现已成为破解人才招聘困境的有力工具。本研究提出一种全新方案：结合联盟链（consortium chain）与星际文件系统（InterPlanetary File System，IPFS）技术，构建去中心化人才招聘系统。该方案允许学生、教育机构与潜在雇主通过联盟链技术对数据进行加密并上传至区块链，同时设置严格的访问控制机制：简历数据的调取必须经过学生本人授权。本系统可助力教育机构与行业合作伙伴构建共生生态，学生能够借此匹配合适的就业岗位，企业则可高效寻访到具备所需专业能力的候选人。最后，本系统可适配各类区块链的特性需求，在区块链通信成本、计算成本、吞吐量与交易延迟等指标上表现优异，可为人才招聘难题的解决提供有效助力。
