Design and Implementation of Storage System for Real-time Blockchain Network Monitoring System

Abstract

Recently, due to the popularity of Bitcoin, interest in the blockchain which is the core technology of Bitcoin, has also increased. Blockchain is a distributed ledger technology that stores transaction information that occurs in P2P(Peer-to-Peer) networks on the ledger of all nodes in a different way than centralized method and verifies whether they are stored correctly. As a result of blockchain technology, not only Bitcoin but also various cryptocurrencies such as Ethereum, Litecoin, Ripple and Bitcoin Cash are being developed. Blockchain is used in various fields because of its features such as integrity and anonymity, but it is also used for illegal transactions and drug transactions. To solve these problems, monitoring system is needed to collect data from blockchain networks and detect abuse and illegal transactions. In this paper, we propose monitoring system for detecting and tracking illegal transactions by collecting and analyzing information in a blockchain network. In addition, we introduce an efficient storage system implemented by Apache Kafka and Apache Storm among the Blockchain monitoring systems.
