DDOS Attack on Crypto
As per Certik, DDoS attacks can also impact crypto and blockchain?
Certik states, "Due to its digital nature, blockchain is susceptible to attack and exploitation. In theory, having a decentralized network distributing computing power worldwide should eliminate single points of failure such as servers or apps. DDoS attacks on a blockchain focus on the protocol layer, with the biggest threat to blockchains being transaction flooding. Traditional DDoS attacks can be executed against a blockchain to slow its operations, and attackers can work within the blockchain ecosystem to perform a DDoS attack".
Certik adds, "Most blockchains have a fixed block size and limit how many transactions fit into a block. By sending spam transactions to the blockchain, attackers can fill the blocks and hinder legitimate transactions from being added to the chain. When this happens, all legitimate transactions will end up in the mempool, waiting for the next block. Legitimate transactions not being added to the blockchain is already a system failure".
Public blockchain is the infrastructure that supports cryptocurrency transactions. Investors need to pay close attention to the security risks when investing in cryptocurrency.
