Abstract
the primary concerns with manual transactions include corruption, lack of
transparency, fraud, and mismanagement of distribution operations, all of which are
created by traditional centralized applications, necessitating the migration to blockchain
technology. In this work, a system is presented to secure and monitor correspondence
between several nodes and store it in a decentralized database in order to secure
distributed ledger transactions and safeguard against fraud and tampering when
transactions are shared by multiple parties. The hashing that blockchain technology
delivers in each transaction ensures a high level of security. The hashing associated with
each transaction confirms all sending and receiving transactions. When a transaction is
sent from one node to another, the other node checks the hash accompanying the
transaction to see if it came from a registered node or an external node. Within the
blockchain system, the nodes will check transaction correspondences. The system has
demonstrated its effectiveness by delivering a more secure messaging system with high
credibility and tamper resistance. In addition, the time it takes to authenticate will be in
real time.
