Scalability, Performance and Robustness #187 Milestone 1: On-going Commitment: Perpetual Scale Regression Testing and Improvement (CILR)

Milestone 1: _On-going Commitment: Perpetual Scale Regression Testing and Improvement (CILR)_

• Focus: Digital Asset will operate 7/24 a continuous test environment with 16 synchronizer nodes and 600 validator nodes, testing each release for regressions at scale. This environment is used prior to any release and major migration to detect regressions. In most cases, these issues are not fundamental but require analysis and some minor refactoring for remediation. The continuous work will be included in this milestone. The large-scale environment will be complemented by instrumenting and adapting existing per-component performance tests and integrating them into the repositories' automated CI/CD workflows.
• Estimated Delivery: Throughout 2026
• Deliverables / Value Metrics:

- CILR: Each incremental improvement delivered as part of this effort will mention the funding through this grant through a (CIP100 / DA-SPR / Incremental) tag in the release notes of the respective repository.

| Milestone | Code | Payment | Acceptance / Trigger | |-----------|------|---------|----------------------| | 1 | CILR | 715,000 CC per month (commencing March 2026) | Monthly payment schedule |
