DDOS Attacks Against Bitcoin Mining Pools: A New Game-Theoretic Analysis With Defense Cost

Abstract

Today, almost all new Bitcoins are mined in mining pools, making their security crucial to the Bitcoin network as a whole. Distributed denial-of-service (DDoS) attacks are the most notable kind of attack against mining pools. Researchers have shown that when mining pools are big enough, they engage in distributed denial of service attacks. DDoS attacks targeting cryptocurrency are occurred, but that no pool has claimed credit for them as of yet. Therefore, we modify the play assessment method to account for the price of anti-DDoS tactics. Assuming we assume that each mining pool's computer power is solely used for mining, defense, and attack, we observe some exciting features. Keeping the peace is in the long term interest of mining pools (1) if a Cyber attack is really very unlikely to succeed. (2) Whether launching or defending against a distributed denial of (Denial - of - service) assault, mining pools' first objective is always to maximize the amount of available computational power for miners.
