Spam Attack Launched On Chainlink Congested The Network

A spam attack was launched on Chainlink recently which ended up congesting the network and increasing the fees on node operators as we are about to find out more in today’s Chainlink coin news.

Chainlink was hit with a spam attack but the team took over measures and allowed the network to overcome the incident. The attackers swamped the network with data requests thus congesting the network and imparting high fees on the node operators.

Manual whitelisting and compensation were able to control the damage from the attack. The oracle platform Chainlink was targeted and the nodes were prevented from providing data to blockchain app developers.

Rory Piant, the director of Community at Chainlink Labs, announced the news on Telegram and explained that Chainlink was successfully able to overcome the biggest on-chain spam attempt adding that the network was able to continue operating normally in the right parameters. During the incident, the attacker tried to spam Chainlink with many requests and Piant said that the attack lasted for a few hours but didn’t quite impact the network’s performance.

Chainlink nodes had to pay higher ETH fees just to continue operating while the attack was ongoing. According to Piant, the node operators were willing to pay the costs in order to maintain the reputation in the long-term despite the higher costs. Many node operators were willing to pay higher fees in order to support Chainlink’s continued operation as it seems that the solution for the spam attack is much more complex that Piant suggests. Other sources suggested that the LINK node operators whitelisted certain data requests so they can be able to handle larger number of requests. This means that only high-profile applications were allowed to request data during the attack.

Chainlink reimbursed some of the node operators that were forced to spend huge amounts in fees as the node operators lost over 700 ETH in total because of the higher gas fees. Chainlink compensated the node operators through the auto-refill scripts and the new grants. It’s still not clear whether Chainlink could solve the spam attack automatically with a new fee model or by simply meeting the needs of the network in real-time.

The spam attack on Chainlink didn’t cause too much distraction so the prices didn’t really do anything. The price of LINK dropped by 14% in the past week compared to the 7.2% drop over the same period. It remains to be seen whether the publicity around the attack will have an impact on the prices
