Ethereum L2 Optimism Disables WebSocket Support on Public Endpoints to Protect HTTP Traffic

According to reports, Ethereum L2 Optimism said on its official Twitter that in order to solve the problem of continuous abuse of public endpoints, Optimism will disable WebSocket service support on public endpoints due to careful consideration and protection of normal HTTP traffic. In the future, if WebSocket support is needed, infrastructure providers such as Alchemy can be used. Optimism recommends that the project run its own nodes or choose to use infrastructure solutions from trusted partners.

Optimism: WebSocket service will be disabled on the public endpoint

Interpretation of the news:


Ethereum Layer 2 (L2) Optimism recently announced on its official Twitter account that it will disable WebSocket service support on public endpoints to prevent the continuous abuse of such endpoints. According to Optimism, public endpoints experience high traffic and usage, which can cause bottlenecks and slow down the normal HTTP traffic that the network relies on. Thus, Optimism carefully considered this issue and concluded that disabling WebSocket support on public endpoints is the best solution to protect normal HTTP traffic and ensure the network operates smoothly.

WebSocket is a popular network protocol that enables real-time communication between web browsers and servers. In Ethereum, WebSocket support is commonly used by developers to query data from Ethereum nodes to build decentralized applications (DApps) and facilitate transactions. However, WebSocket support on public endpoints is also prone to abuse, and bad actors can exploit it to launch DDOS attacks, spam the network with requests, and overload the server. This can cause widespread disruption to the entire Ethereum network, affect the performance of DApps, and hinder the adoption of Ethereum.

Optimism emphasized that although it is disabling WebSocket support on public endpoints, it is not eliminating it entirely. Instead, developers can still use WebSocket support through infrastructure providers such as Alchemy, which offer more robust and secure WebSocket support tailored to Ethereum. Optimism also recommends that project owners run their own nodes or choose to use infrastructure solutions from trusted partners. Running nodes means that developers have full control over their network communication and can prevent unauthorized access and abuse of their endpoints.

In conclusion, L2 Optimism’s decision to disable WebSocket support on public endpoints is a strategic move to safeguard the Ethereum network and strengthen its infrastructure against malicious attacks. By prioritizing HTTP traffic and working with trusted infrastructure providers, developers can continue building DApps and using Ethereum with confidence. However, this decision also highlights the challenges faced by Ethereum and other blockchain networks in ensuring security, scalability, and accessibility while retaining their open and decentralized nature.
