Cardano Network Successfully Fends Off DDoS Attack: Details

As an experienced analyst, I closely followed the recent DDoS attack on the Cardano network and was impressed by its resilience and ability to mitigate the threat effectively. The attack, characterized by a surge in complex transactions aimed at overloading the network, was neutralized thanks to the robust mechanisms of the blockchain and the quick actions of key figures within the Cardano ecosystem.


On Taylor evening, the Cardano blockchain encountered a powerful distributed denial-of-service (DDoS) assault. This type of attack is marked by an overwhelming increase in harmful traffic intended to interrupt the network’s functionality. Yet, the resilient safeguards built into Cardano successfully thwarted the onslaught, preserving its uninterrupted performance.

Cardano Not Disrupted By the DDoS Attack

As a researcher, I’ve come across an intriguing revelation from El Raulito_cnft, CTO of Fluid Token, regarding a recent attack on their network. The assault began at block 10,487,530, with each transaction involving the execution of 194 REWARD type smart contracts and consuming a relatively small amount of 0.9 ADA. This tactic aimed to overwhelm the network by filling every block with these intricate transactions, resulting in a backlog that degraded the network’s performance. In doing so, the attackers could transmit large transactions at minimal cost.

Philip Disarro, the founder of Anastasia, the Cardano development firm, reportedly took a significant part in putting an end to the threat. Disarro’s swift and public reaction on X appears to have swayed the attacker into halting their actions.

As a researcher studying cybersecurity incidents, I came across an instance where a DDoS attacker paused their assault upon seeing my tweet. Unfortunately, it was too late as the damage to their funds had already been inflicted. I can’t help but express gratitude for this unintentional contribution to our cause at Anastasia Labs – the development of open-source smart contracts – and the funding of Midgard.

As an analyst closely following the Cardano community, I observed the recent attempt to DDoS (Distributed Denial of Service) attack on our network with great interest. In response, a prominent figure within our ecosystem, Big Pey, reassured the community via his platform, stating “Today, someone attempted to DDoS Cardano. Fortunately, very little impact was felt, and the network remained stable. ADA‘s resilience shone through.” This message resonated with many in the community, reflecting our collective confidence in the robustness of Cardano’s infrastructure and security protocols.

Jason Matias, founder of The Art of Selling Art, eloquently explained the effect of a DDoS attack on Cardano’s network operations through a vivid description. “Currently, the DDoS attack against Cardano manifests as those grey gear icons,” he said, pointing out the spam transactions being sent that result in larger, more complicated blocks to process.”

The implementation of Cardano’s extended Unspent Transaction Output (eUTxO) model played a crucial role in minimizing the damage caused by a DDoS attack. Unlike account-based models employed by leading blockchains such as Ethereum, eUTxO has a unique structure. In this model, each transaction output carries not just a value but also a script that sets forth the conditions for the next use of funds. This feature enables the protocol to manage individual transaction outputs independently.

This architectural decision improves both scalability and security by ensuring that transactions run independently of one another. By preventing transactions from influencing each other, potential issues, such as those caused by a DDoS attack, are contained and do not impact the processing of other transactions. Consequently, the network can sustain high levels of throughput and dependability even during times of stress.

After the recent assault on the market, I’ve observed that the price of ADA remained unaffected. However, I’m pleased to report a positive development: over the past 24 hours, the price has climbed by 5%, reaching a current value of $0.39.
