PROFILE
Pol Espinasa
Contributed to the bitcoin/bitcoin repository by delivering three features over three months, focusing on deprecation management, fee calculation precision, and documentation clarity. Led the deprecation of legacy transaction-fee controls by updating RPC commands, CLI arguments, and related tests, reducing technical debt and aligning with long-term project goals. Refactored the CFeeRate class in C++ to use the FeeFrac data structure, improving fee-rate accuracy and consistency across modules. Enhanced developer guidance by clarifying TRUC transaction behavior in documentation, supporting smoother onboarding and protocol adoption. Demonstrated expertise in C++, Python, data structures, and documentation standards while collaborating closely with core development teams.

Aug 1, 2025August 2025 monthly recap for bitcoin/bitcoin: Delivered documentation clarification for TRUC Transactions within package contexts, stating that sub-minimum relay feerate is permissible when part of a package and outlining the exception to the general package-fee and minimum relay rules. This month did not include major bug fixes; the focus was on improving developer guidance and reducing relay-related confusion. Overall impact: clearer protocol behavior for contributors and operators, supporting smoother TRUC package adoption. Technologies/skills demonstrated: documentation standards, commit-based traceability, cross-team communication, and adherence to repository guidelines.

May 1, 2025May 2025: bitcoin/bitcoin feature delivery improving fee-rate precision by refactoring CFeeRate to use the internal FeeFrac representation. This change yields more accurate fee calculations, better edge-case handling, and greater consistency across fee-related modules. No major bugs fixed this month. Impact: higher reliability of fee estimation and transaction prioritization, with improved maintainability. Technologies/skills demonstrated: C++ refactoring, FeeFrac data-structure, numerical precision, code maintainability, and collaboration with core devs.
