A Blockchain Work Permit is a digital document that is securely stored on a decentralized ledger. It is used to prove the identity of a worker and provides an immutable record of the worker's qualifications, certifications, and work history. The work permit can be shared with employers or other organizations, allowing for greater transparency and trust in the hiring process. By using blockchain technology, work permits are tamper-proof and can be updated and verified in real-time, ensuring that only valid information is stored on the ledger.
