A Review on Detection and Prevention of the DDoS Attacks in the Blockchain

Now a day's, blockchain technology is an emerging technology. The Blockchain is a distributed network technology that uses a decentralized approach to information storage. When transactions are performed using blockchain technology, security concerns are a top priority. It required more storage and used more energy. Security is affected by endpoint vulnerability. Attackers exploit this weakness to damage the system and carry out attacks. A DDoS attack is the most harmful attack on the blockchain peer-to-peer network. It affects the unavailability of every internet-based network. Node crashes, software failure, network congestion, and a bloated ledger are the aspects of blockchain DDoS attacks that are most affected. In this paper we find out solutions to prevent this attack from occurring by increase system security, and defend against security attacks.
