reservations, and car rental services. The contemporary
centralized traveling systems are complicated, expensive,
and nontransparent. Ozone connects customers with airlines and proposes a cost-efficient solution as it eliminates
the role of mediators, such as online travel agents to commit the transactions. Thus, it lowers the chances of flight
cancelations, overbooking, and delays to serve passengers
in a much convenient way. The ozone framework divides
system users into three categories, such as recognized as
buyers, distributors, and suppliers. For instance, airline in
an ozone framework is regarded as a supplier because it
offers traveling services to the passengers. Ethereum
blockchain-based smart contracts act as the backbone of
the Ozone framework. They are used to grant highly
secure and auditable services to publishers, settlers, customers, and distributors. Ozone token, implemented on
Ethereum ERC: Non-fungible Token Standard (ERC721),
can help to ensure trusted provenance of nonfungible
assets [4], [26].

FLIGHTCHAIN
FlightChain is a private-permissioned Ethereum and
Hyperledger Fabric supported system that provides a single and synchronized view of flight data. FlightChain uses
smart contracts to perform the following:
1) collect data from multiple flights;
2) authenticate the provenance of data;
3) merge verified data to decide the truth.
However, the network design of FlightChain is very
complex and it is not very scalable. In the FlightChain
architecture, each network node hosts a virtual machine
that runs processes including parity, node JSN, couch DB,
and an adapter process to manage flight data. Parity client
runs on every node in the FlightChain network to establish
a Peer-to-Peer (P2P) connection . Couch DB is an open
source document-oriented database that stores the flight
