Penumbra Update Announcement: March 27, 2024

We’re excited to announce a major update to the Penumbra protocol, as part of our continuous efforts to improve security, efficiency, and functionality. This update includes a range of enhancements, motivated by our ongoing commitment to security and performance, and in response to valuable feedback from the community and security audits by Zellic and Zellij.

Key Changes:

  • DEX Circuit Breaker Redesign: In accordance with recommendations from a security audit by Zellic, we’ve redesigned the DEX circuit breaker for improved reliability.
  • Shielded Pool Update: We’ve updated the shielded pool to enhance privacy and efficiency by removing the supply tracking logic, a change prompted by findings in a security audit by Zellij.
  • DEX Asset Pair Flexibility: The DEX now supports fixed asset pairs defined via chain parameters, enhancing its flexibility and resilience against dynamic routing challenges.
  • CompactBlock Epoch Index: Added an epoch index to the CompactBlock, enabling external integrators to reconstruct state fragments more effectively.
  • Validator Uptime Storage Optimization: Moved validator uptime tracking to nonverifiable storage, significantly reducing storage requirements for nodes.
  • Offline Migrations for JMT Storage: Introduced support for offline migrations in the JMT storage implementation, improving our ability to update storage structures without impacting network operation.
  • Protocol Specification Clarifications: We’ve made significant updates to the protocol documentation, enhancing clarity and comprehensibility for developers and integrators.
  • CometBFT v0.37.5 Support: We now officially recommend CometBFT v0.37.5, incorporating improvements and fixes from the CometBFT team.
  • Protobuf Interfaces for Delegations and Swaps: Added new protobuf interfaces to facilitate the development of staking and trading interfaces in the web extension, enhancing user experience.
  • Expanded Test Coverage: Thanks to our new mock consensus harness, we’ve greatly expanded test coverage, especially around staking logic.

These updates are part of our ongoing effort to ensure Penumbra remains at the forefront of privacy-centric decentralized finance. We’re grateful for the community’s support and feedback, and we look forward to seeing how these improvements pave the way for new and exciting applications on the Penumbra network.

We’re excited to announce that our comprehensive guide and associated scripts for setting up a Penumbra node and validator have been updated to support the latest Penumbra version, v0.69.0, as of March 11, 2024. These updates ensure compatibility with the most recent advancements and features introduced in Penumbra, allowing users to seamlessly operate within the Penumbra ecosystem.

The update introduces streamlined processes for both node setup and validator initiation, accommodating the Penumbra network’s evolving requirements. The node setup script now includes automatic IP detection with a manual override option, ensuring that users can correctly configure their nodes even when automatic detection fails. This feature is crucial for maintaining connectivity and synchronization with the Penumbra network.

For those looking to contribute to the network’s security and decentralization by running a validator, the updated validator script simplifies the process. It leverages pcli, Penumbra’s command-line interface, directly from the user’s PATH, making the script more accessible and easier to use. Additionally, we’ve removed the dependency on jq for JSON processing, streamlining the script and reducing the setup requirements.

These updates are part of our ongoing commitment to supporting the Penumbra community by providing accessible and up-to-date resources. Whether you’re a seasoned node operator or new to the Penumbra ecosystem, our guide and scripts are designed to help you get up and running with minimal hassle.
