Worked on the ZcashFoundation/zebra repository to enhance the verbose getblock RPC response by adding a per-block transaction count (nTx), improving block visibility for release tooling and block explorers. The implementation derived the nTx value directly from the transaction array, ensuring no additional storage or computation overhead. Regression and serialization tests, along with fixtures, were updated to maintain reliability and safety as the new field was introduced. This work, using Rust and backend API development skills, aligned Zebra’s RPC output more closely with Bitcoin Core, supporting community expectations and reinforcing observability without compromising performance or increasing the storage footprint.
