• Blockchain technology can provide a tamper-evident audit trail for aviation documents and credentials.
• The technology can reduce verification time and improve compliance for airlines and regulators.
• Blockchain can enhance supply chain management by providing a transparent and secure record of part manufacture, shipment, and maintenance activity.
• Credential portability and verification can improve staffing agencies, crew rostering, and cross-border contractors.
• Blockchain can also improve baggage handling by recording every scan and custody transfer of a checked bag on a shared ledger.

The aviation industry may benefit from blockchain's ability to provide a secure and efficient method for verification and compliance, potentially reducing costs and improving safety. However, the implementation of blockchain must be carefully controlled to address concerns around data integrity and privacy.
