Using Consensus Algorithm for Blockchain Application of Roaming Services for Mobile Network

Blockchain technology has recently emerged as one of the most innovative
solutions on the market. It is predicted to become as popular as the internet was
in its early days during the 1980s. With the use of a consensus algorithm, the
blockchain creates a cryptographic record that is unalterable. The system uses
a combination of repeated sequence hashing and failure tolerance to achieve
this outcome. Decentralization, immutability, anonymity, and accountability are
just a few of the key features of blockchain. Due to these attributes, many
businesses in various industries are now exploring the possibility of
incorporating blockchain into their IT systems. Consensus algorithms are a
vital component of blockchain technology and play a crucial role in ensuring
the reliability and efficiency of the blockchain. The Raft Consensus prevents the
generation of new blocks until transactions are confirmed. This also saves
storage space, particularly during periods of low transaction activity, as
unoccupied blocks do not consume storage space. To evaluate the efficiency of
the Raft consensus algorithm, a simulation of a roaming services application
for mobile network operators (MNOs) was performed. This simulation assessed
the blockchain's efficiency in terms of network performance. The results
indicate that implementing this technique could significantly increase
transaction volumes
