Abstract:
This thesis proposes a blockchain-based solution for the issuance and verification of professional documents of teachers in pre-university education, with the aim of creating a secure digital portfolio that can prove the authenticity of the documents in order to combat inefficiency, document loss and fraud in teacher evaluation processes.
Our solution is based on two smart contracts developed with integrated security measures and gas optimization techniques, one to manage educational resources created by teachers and another to manage credentials such as diplomas, certificates and attestations. Our solution is based on zk-Rollup integration to significantly reduce costs so that it is suitable for the education system.
The research demonstrates how blockchain can contribute to a more efficient and credible evaluation system, supporting the digital transformation of educational administration.
