KEY TAKEAWAYS
- Aleph Zero’s Mainnet 15.2 release enhances decentralization and validator accountability, building on Testnet 15.0’s progress.
- The update introduces on-chain ABFT performance monitoring, providing transparency and insights into validator behavior.
- New mechanisms improve censorship resistance and allow automatic banning of underperforming validators, ensuring robust network performance.
- Additional improvements include enhanced network security, stability, and a new network sync metric for better diagnostics.
Aleph Zero has announced the release of Mainnet 15.2, introducing significant upgrades aimed at increasing decentralization, strengthening validator accountability, and enhancing network transparency. This update builds on the progress made in Testnet 15.0 (Menard) and sets the stage for a more permissionless and resilient validator ecosystem.
On-Chain ABFT Performance Monitoring
Mainnet 15.2 introduces on-chain reporting of validator performance scores based on Aleph Zero’s asynchronous BFT (ABFT) consensus. This feature is designed to enhance transparency and provide the ecosystem with a clearer understanding of validator behavior.
Validators report how far other validators are lagging behind in the current consensus round. These scores are aggregated, multisigned, and submitted to the chain as unsigned transactions. The performance data is publicly accessible on azero.dev in the Staking → Performance section, offering nominators and observers actionable insights into the health and reliability of validators. This development is a foundational step in ensuring that block finalization is decentralized and based on measurable validator performance.
Improved Censorship Resistance and Validator Accountability
The release enhances censorship resistance within the ABFT protocol, making it more challenging for any actor to manipulate the network by selectively excluding validators from participation. This promotes a fair and robust consensus process.
Additionally, a new mechanism allows the network to automatically ban validators who consistently underperform according to ABFT metrics. Although this feature is initially disabled, it is scheduled to be enabled after a brief period of Mainnet testing to maintain high performance standards across the network.
Additional Improvements and Fixes
Mainnet 15.2 includes several enhancements aimed at improving network security, stability, and user experience. NonTransfer proxies are now restricted from interacting with the Identity pallet, preventing unintended behavior. Validator committee selection is randomized per session, addressing slow block creation and improving overall liveness. Resistance to randomness attacks has been strengthened to further secure the consensus process.
Furthermore, a new network sync metric has been introduced to improve monitoring and diagnostics, and a bug fix related to communication between the latest nodes and validators on Aleph Node 14.2 has been implemented.
This update marks a major step toward full decentralization by removing the dependence on reserved validator committee spots and instead selecting any validator that meets performance standards. For more details on validator performance and the latest changes, visit here.
