Advanced DAG-Based Ranking (ADR) Protocol for Blockchain Scalability

In the past decade, blockchain has evolved as a promising solution to develop secure distributed ledgers and gained massive attention. However, current systems face problems of limited throughput, poor scalability, high latency. Due failure consensus algorithms in managing nodes’identities, technology is considered inappropriate for many applications, e.g., IoT environments, because scalability. This paper proposes mechanism called Advanced DAG-based Ranking (ADR) protocol improve scalability throughput. The ADR uses directed acyclic graph ledger, where nodes are placed according their ranking positions graph. It allows honest use Direct Acyclic Graph (DAG) topology write blocks verify transactions instead chain blocks. By using three-step strategy, this ensures that system secured against doublespending attacks higher throughput first step involves safe entry into by verifying private public keys. next developing an advanced DAG ledger so can start block production transactions. third step, algorithm developed separate created attackers. After eliminating attacker nodes, ranked performance system, true arranged topological order. As result, suitable applications Internet Things (IoT). We evaluated on EC2 clusters with more than 100 achieved better transaction liveness network while adding malicious nodes. Based simulation results, research determined transaction’s was significantly improved over blockchains like Applications (IOTA) ByteBall.
