Why Source-available at the core?
A source-available core creates structural advantages — not just community engagement. By keeping Midaz source-available, we enable:
- Transparency: Every line of the core ledger is visible and auditable. No hidden logic. No opaque behavior.
- Independence: Institutions control their stack and retain access to the source code of the ledger that holds their money.
- Extensibility: Teams can adapt the ledger to their regulatory, operational, and product requirements.
- Trust by design: Visibility reduces systemic risk. You understand how your core infrastructure behaves — because you can inspect it.
What this means for your business
For decision makers evaluating Lerian, an open-by-design platform translates into concrete business benefits:
- Source-code access: Midaz is source-available under Elastic License 2.0, so your team retains access to the ledger source code.
- Third-party auditability: Your security team, auditors, or regulators can inspect the Midaz code directly.
- Extensibility: Your engineers can inspect and extend Midaz to meet operational requirements.
