Base introduces security monitoring system named Pessimism

Quick Take

  • Coinbase’s Base Layer 2 introduced Pessimism, a security monitoring system for the Optimism ecosystem.
  • The objective behind Pessimism is to detect security threats and vulnerabilities in OP Stack-based networks.

Coinbase’s Base Layer 2 network has introduced Pessimism, an open-source monitoring system designed to enhance security oversight across networks in the Optimism ecosystem. Pessimism seeks to identify protocol threats and security vulnerabilities specific to networks created with the OP Stack and other EVM-compatible chains.

The Pessimism system comprises three primary subsystems: ETL (extract, transform, load) subsystem, Risk Engine, and Alerting. Together, these systems can parse, analyze, and flag potential security concerns. Coinbase has expressed its intention to expand Pessimism’s capabilities to bridge monitoring, emphasizing features like withdrawal safety and the detection of potential security issues.

Users and developers have been invited to suggest features or raise issues on Pessimism’s GitHub page.

This announcement follows Coinbase’s statement last month, where it shared plans to fully decentralize Base in the future. The aim is to attain network decentralization by introducing fault proofs and leverage diverse client software to maintain network censorship resistance.
