# Mojaloop Evolution Workstream
This workstream is aimed at carrying out a significant evolution in Mojaloop's most critical central services:
- Replacing the accounting ledger functionality at the heart of Mojaloop with TigerBeetle.
- Replace the heart of the settlement engine with TigerBeetle functionality updating it with Settlement V3 capabilities.
# Business Justification
This workstream has strategic importance; TigerBeetle is the next generation ledger technology developed specifically with Mojaloop in mind, and offers the potential of a transaction throughput performance improvement of at least an order of magnitude.

# Latest Update (Summary)
# Forensic Audit
The forensic audit redesign is ready for implementation but awaits funding from forthcoming adoption projects. No significant progress is expected until mid-Q1 2026.
# New Accounting Model
The new accounting model is broadly agreed and represents a major shift toward alignment with international accounting standards. This addresses concerns raised by global institutions and enhances Mojaloop’s credibility as a financial infrastructure platform. The initial target is TigerBeetle, though the team has not yet decided whether a MySQL version of the new model will also be produced.
# TigerBeetle Integration
Given the accounting model’s increased complexity, TigerBeetle is the preferred ledger engine. Integration planning is underway, with work expected to begin before Christmas.
# Settlement v3
Settlement v3 introduces deterministic settlement batches, addressing long-standing reconciliation challenges and enabling multi-scheme scalability. TigerBeetle will store settlement batch keys, while SQL components and admin APIs will require substantial enhancement to support model configuration, batch tracking, and settlement operations.
