The Cardano blockchain recently fell victim to a Distributed Denial of Service (DDoS) attack.
Cardano Exhibit Distinct Feature
DDoS attacks are hacks targeted at vulnerabilities in a system. It oftentimes comes in the form of sending more traffic to a network than it can handle or overwhelming an application with more requests than it can process. The common form of DDoS attack is usually transaction flooding which ends up compromising the availability of the original users of a protocol.
Based on the Cardano insider updates provided, the exploit which started at Block 10,487,530, had very limited impact on the mainnet. There is no single point of failure, especially as the load is spread out on the network. As a result, no major chain halt happened in Cardano, instead, operations will continue as usual.
CTO of Fluid Tokens “elraulito” noted that the attacker executed each transaction with a total of 194 smart contracts. He also noted that the attacker is spending 0.9 ADA per transaction while filling each block with many of these transactions.
More DDoS Attacks on Crypto Blockchain
While the occurrence of hacks and scams are common, such resistance to attack is quite rare in the crypto ecosystem. In recent times, Cardano is the first blockchain to exhibit such traits. Markedly, Solana’s Phantom Wallet experienced a similar attack at the beginning of this year. Unlike Cardano, it was forced to temporarily suspend all wallet services until the vulnerability was fixed.
Similarly, Mantra Network, a zero-knowledge proof-powered layer-2 blockchain, suffered a DDoS attack that overwhelmed the blockchain’s node with over 135 million remote procedure call (RPC) requests. The network assured its users of continued secure operations as well as the safety of funds. However, Kenny Li, co-founder of p0x labs, a cryptographic development team behind Manta Network, acknowledged that communication between applications and the blockchain was severely impacted.
