Abstract In the past decade, blockchain has evolved as a promising solution to develop secure distributed ledgers and has gained massive attention.
However, current blockchain systems face the problems of limited throughput,
poor scalability, and high latency. Due to the failure of consensus algorithms in
managing nodes’identities, blockchain technology is considered inappropriate
for many applications, e.g., in IoT environments, because of poor scalability.
This paper proposes a blockchain consensus mechanism called the Advanced
DAG-based Ranking (ADR) protocol to improve blockchain scalability and
throughput. The ADR protocol uses the directed acyclic graph ledger, where
nodes are placed according to their ranking positions… More >
