PROFILE
Joosep Jääger
Joosep Jaager enhanced the formal ledger conformance tooling in the IntersectMBO/formal-ledger-specifications repository, focusing on correctness, maintainability, and governance reliability. Over four months, he delivered features such as accurate deposit calculations across certificate types, centralized error handling for UTXO checks, and flexible deregistration certificates. Using Agda and functional programming, Joosep refactored core modules to reduce financial risk and improve auditability, while also tuning ledger parameters for better test alignment. His work consolidated governance validation logic, enforced non-zero treasury withdrawals, and improved documentation, resulting in a more robust, readable, and future-proof formal specification for blockchain protocol conformance.

Dec 1, 2024Month: 2024-12 – Concise monthly work summary focusing on key accomplishments in the IntersectMBO/formal-ledger-specifications repo. Key achievements: - Ledger Parameter Tuning: SlotsPerEpoch adjusted to improve epoch sizing and test alignment in Conway ledger specification. • Change: hardcoded SlotsPerEpoch increased from 100 to 4320. • Commit: 74a61ee8919ab1c021ae14256f82434338b0c554 (Tweaked SlotsPerEpoch (#623)). - Resulting improvements: enhanced epoch timing accuracy, reduced fragility in tests, and better alignment with network test scenarios. - Future work: plan to expose the SlotsPerEpoch parameter for external configuration (externalize tunable parameter). Technologies/skills demonstrated: - Ledger/Conway specification understanding, parameter tuning, and impact assessment on epoch sizing. - Version control and traceability with precise commit references. Business value: - More reliable epoch calculations reduce test failures and enable more consistent network simulations, supporting faster iteration and higher confidence in protocol behavior.

Nov 1, 2024In November 2024, I strengthened the reliability and maintainability of the formal ledger conformance tooling in IntersectMBO/formal-ledger-specifications. The work focused on correctness in deposits and consistency of error reporting for conformance checks, delivering two business-critical improvements in a single repository. Key features delivered and bugs fixed: - Corrected deposit change calculation across certificate types (pool registration, delegation, DRep registration/deregistration) and refactored updateCertDeposits to be used by updateDeposits, ensuring accurate deposits and refunds. (Commit 0158b1c882a87b017ab829ac6c3bca27df164e9b) - Introduced a centralized genErrors-based error handling for UTXO conformance checks, replacing handwritten error messages to improve consistency, maintainability, and future extensibility. (Commit f93035b552d9778cc7c96dc24a40054f4073a6e1) Overall impact and accomplishments: - Reduced financial risk from incorrect deposit accounting and refunds, enabling more reliable conformance operations across certificate flows. - Improved code maintainability and auditability through refactoring and centralized error handling, facilitating faster future changes and better consistency across checks. Technologies/skills demonstrated: - Code refactoring for correctness and maintainability - Design and implementation of centralized error handling (genErrors) - Domain-focused testing and validation of conformance logic in a compliance-critical module
