Introduction
Blockchain technology is often presented as a solution to fragmented aviation data.
Its potential applications include ticketing, loyalty programmes, identity verification, baggage tracking and aircraft records.
The Legal Value Depends on the Underlying Data
A blockchain can make a record difficult to alter, but it cannot guarantee that the original information was correct.
Legal responsibility therefore remains important at the point where information enters the system.
Identity Verification Creates Privacy Issues
A decentralised identity system may reduce duplication but can also create challenges concerning data minimisation, correction and deletion.
Conclusion
Blockchain should not be adopted simply because it is technologically attractive.
Aviation businesses should first identify the legal problem they are trying to solve and then determine whether blockchain actually improves accountability, security and passenger rights.
