BlockFlow is a decentralized Software Defined Networking (SDN) controller that leverages blockchain technology to enhance network security and reliability. Traditional SDN architectures rely on a centralized controller, which can become a single point of failure and is vulnerable to attacks. BlockFlow addresses these issues by distributing the control plane across multiple nodes using a blockchain-based consensus mechanism. This decentralization ensures that the network remains operational even if some nodes fail or behave maliciously. BlockFlow also provides a transparent and tamper-proof record of network configurations and changes, enhancing trust among network participants.
