Denial of Service, or DoS, is a type of cyberattack that aims to make a machine or network resource unavailable to its intended users. Attackers achieve this by disrupting services of a host connected to the internet. In the context of blockchain, a DoS attack could flood a network with excessive requests or invalid transactions. This overload prevents legitimate users from accessing services or processing transactions. Such attacks compromise system availability.
Context
DoS attacks pose a constant threat to the availability and performance of cryptocurrency networks and exchanges. While major public blockchains are designed with some resilience against basic DoS, more sophisticated distributed denial of service attacks remain a concern. Ongoing security research and protocol upgrades continuously work to fortify these systems against such disruptive actions.
The OWASP Smart Contract Top 10 for 2025 highlights persistent architectural flaws, posing systemic risk to decentralized finance protocols and user assets.
