Today, the number of cyberattacks on computer networks, especially local area networks and the Internet, has increased dramatically, and these attacks have become much more complex. Many intrusion detection systems (IDS) and signatures are being designed and developed to detect these types of attacks. In recent years, with the introduction of blockchain, which is a secure distributed database in decentralized networks, a dramatic change has occurred in computer networks. This technology can create consensus and trust between intrusion detection systems to increase the stability of the cooperating networks among IDS systems. Therefore, the combination of these two systems can have better performance than previous generations of IDS. Blockchain technology has many applications in the world of cryptography and network security due to features such as data integrity, availability, and decentralized management. Information security in this network is essential for the proper functioning of intrusion detection systems and firewalls. These features can be found in the Hyperledger Fabric network. Due to the use of asymmetric encryption and blockchain, this network transmits and records information securely and quickly in the network. In this project, using blockchain technology, we are trying to create a network of IDS nodes where each node can add its own rules to the blockchain database. In this way, the other nodes of the chain use the rules of other nodes to improve their intrusion detection system efficiency after consensus and synchronization. Also, due to the decentralized nature of the blockchain, a central identity control is not required to approve/disapprove the nodes and rules added to the database, and consensus mechanisms do this
