November 2024—Paladin (LF-Decentralized-Trust-labs/paladin) delivered substantial privacy, reliability, and deployment improvements across the stack. Key work included Zeto nullifier integration into the state distributor with coordinator/local generation and BuildNullifiers, core state distribution enhancements with expanded tests, and Zeto circuit/build configuration updates. Configuration was simplified by removing full ABIs and unnecessary addresses, while a comprehensive nullifier system was rolled out across interfaces with DB schema updates, query parity, and documentation. Qualification flow was consolidated and migrated to TxManager, supported by testbed readiness and identities. Testing, QA, and CI were stabilized with coin-type tests, parallel/queued submission tests, startup retry logic, and cross-platform docker builds. Architecture and docs were refreshed to improve developer onboarding and governance, while ongoing crypto, distributed systems, and DB work expanded business value and reliability.
