Plasma’s architecture evolves rapidly to support high-throughput, stablecoin-native use cases. Timely upgrades:
Protect against security vulnerabilities
Improve performance for payment workloads
Maintain compatibility with Plasma’s consensus layer and RPC interface
Outdated nodes may experience sync failures, degraded performance, or security issues. As non-validator nodes often serve critical RPC traffic for payment apps, staying up to date is essential.
Most non-validator node upgrades require 15–30 minutes of downtime. Major releases introducing new features or consensus changes may require longer sync windows.
Non-validator node upgrades typically involve pulling a new Docker image, updating configs, and restarting the service.
Notify applications: Inform connected services about planned maintenance.
Verify consensus endpoint compatibility: Ensure new non-validator client versions work with current consensus endpoints.
Update non-validator client configuration: Apply any new configuration options for enhanced features.
Test RPC endpoint functionality: Verify payment application compatibility after upgrade.
Monitor transaction processing: Ensure normal operation for USD₮ transfers and custom gas operations.
Review any configuration changes required for new features or enhanced payment processing capabilities before restarting services. Pay particular attention to changes affecting custom gas token support, zero-fee transaction processing, or payment application RPC interfaces.Deploy upgrades in stages when operating multiple non-validator nodes, starting with non-critical instances before upgrading primary payment infrastructure. Monitor the first upgraded node carefully during initial operation, particularly for transaction processing and payment application connectivity, before proceeding with additional nodes.
Consensus sync: Check endpoint connectivity, credentials, and allowlist status
RPC errors: Validate configuration, version compatibility, and updated interfaces
Performance regression: Monitor resource usage and review release notes
Upgrading Plasma non-validator nodes is essential to maintain reliable, secure RPC infrastructure for stablecoin-based applications. Following structured upgrade and validation procedures minimizes risk and ensures seamless performance.
