+
+During the **WE BUILD MVP (pilot) phase**, the WP4 Trust Infrastructure group acts as **Ecosystem Authority** and **Trusted List Provider** for all participating entities. The LoTL is the trust anchor in the ETSI TS 119 612 model: it references the Trusted Lists for PID Providers, Wallet Providers, and other entity types, enabling Wallet Units and Relying Parties to validate certificates and trust anchors. In the production phase (MVP+), the European Commission and Member State TLPs take over these roles per the [Trust Infrastructure Schema](task2-trust-framework/trust-infrastructure-schema.md). See [LoTL automation and TL integration](task4-trust-infrastructure-api/lotl-automation-and-tl-integration.md) for production and publication details.
