April 2026: Security-focused SDK enhancements and release readiness for bob-collective/bob. The month delivered key features for authenticated access, a targeted security fix, and a production-ready SDK release. Key features delivered: - Gateway SDK API Key Authentication implemented: added apiKey parameter to the SDK constructor; when provided, API requests are sent with a Bearer token in the Authorization header to enable authenticated access to the Gateway API. Commits: d436f7dfacfe2bf9d922f5b12de68ede903f7a31; d2f5ad74e7f6082c3f318db01801fe263b9d8ccf. Major bugs fixed: - API key length validation tightened to 32 characters to strengthen security and input validation. Commit: d2f5ad74e7f6082c3f318db01801fe263b9d8ccf. SDK release and release readiness: - SDK Release 5.4.0 prepared: version bumped to 5.4.0 in package.json to reflect a production-ready release with potential new features and fixes. Commit: 0e2c3566760520f29a2f661db741ed8f3d6252c1. Overall impact and accomplishments: - Strengthened access control and onboarding for enterprise clients by enabling authenticated gateway access; improved security posture and reliability; established a maintainable release baseline for future iterations. Technologies/skills demonstrated: - Secure API design and credential handling (Bearer tokens), SDK constructor design, semantic versioning, and disciplined release processes with clear commit traceability.

July 2025 monthly summary for developer work across bob-collective/bob and pubky/pkarr. Focused on delivering targeted features, improving observability, and restoring stability in build/test workflows. Business value delivered includes clearer operational visibility, faster debugging for relayer events, reduced integration risk from API surface changes, and a more maintainable codebase for JavaScript bindings and WASM workflows. Key features delivered - bob-collective/bob: Relayer Block Hash Handling and Logging Improvements - Rename relayed_blockhash to best_blockhash in the relayer module for clarity; adjust logging for fork detection from debug to info; extend regtest sleep to 150ms to allow more time for block propagation; fix debug log to display the best block hash instead of the relayed block hash. - Commits: 2012cf9e394c735546cb0665b6483c38b75f03af; e8785daa586e185198fb8005db229dc736ade9eb - pubky/pkarr: Unified JavaScript Client API - Refactors JavaScript bindings to use a unified pkarr::Client instead of a separate RelaysClient, simplifying the API and consolidating relay functionality within the main Client. - Commit: 25910d77d4aed96ed40690ef1aeadc0929f0892f - pubky/pkarr: Rollback to stable WASM/JS bindings and build workflow (bug fix) - Reverts changes to WASM build/test workflow, pkarr crate dependencies, JS bindings dependency versions, and build configuration to restore a stable, working state. - Commits: 4df701590da66f7bfa8bb9e2109189357ddc67a8; a0ae0a91a19064c3807082d73618e4860bc010d2; fc2d5d476b77e1ebafe3a53ef52cd159c041ada1; c1815308de58e47e6058adc7db8efec3eba29d66 Major bugs fixed - Reversion of WASM/JS bindings and build workflow to a known-good baseline, restoring stable dependency versions and build configuration, reducing flakiness in CI and local builds. - Ensured cargo checks and dependency resolutions align with pre-change stable state, mitigating runtime and test failures after experimental bindings changes. Overall impact and accomplishments - Increased reliability and observability of the relayer by exposing best_blockhash and improved logging, accelerating diagnosis of fork events and block propagation issues. - Streamlined API surface in pubky/pkarr by unifying client access under pkarr::Client, reducing maintenance overhead and potential integration points. - Restored build stability and test reliability across WASM/JS bindings and related toolchains, lowering release risk and enabling smoother iteration cycles. Technologies/skills demonstrated - Rust: module refactoring, logging, and debugging improvements in the relayer. - WASM/JS bindings: stabilization and unification of client bindings; dependency/version management. - Build/test workflows and CI: reverting to stable configurations, Cargo.toml stewardship, and workflow reliability. - Cross-repo coordination and change management to minimize integration risk and maintain business momentum.

June 2025 monthly summary for bob repo focusing on Relayer module improvements, API enhancements, testing/performance improvements, observability, and contract bindings with deployment scaffolding. Highlights include significant refactor of Relayer core, initialization simplification, public API expansion (contract_address getter), regtest performance tuning, improved logging via tracing, and generated PellBedRock bindings with deployment helper. Removed an unnecessary period-start hash validation in FullRelay contract, simplifying validation and tests.
