Unconditional Social Cash Transfer (USCT) programs help families meet their basic needs for well-being and safety and serves as their path to self-sufficiency. USCT are cash payments provided to financially disadvantaged or vulnerable people or households without requiring anything in return (i.e. without conditionality).
This demo covers only a small fraction of a USCT user flow for the purpose of using various Building Block APIs. For a more comprehensive visualization of the use case visit the [GovStack USCT simulation](https://www.govstack.global/our-offerings/govspecs/simulation/).
## Which GovStack features are demonstrated?
With this use case implementation, we demonstrate the GovStack approach through...

**One possible way to implement the** [**GovStack Specifications**](https://govstack.gitbook.io/specification/)
Browse through all the stack components on the left-hand side menu, to explore the technical details on how we put the specifications into practice.

* BB Identity: MOSIP
* BB Payment: Mifos Payment Hub
* BB Information Mediator: X-Road
* BB Digital Registry: OpenIMIS
* BB Consent: iGrant
Building Block Software has been selected through a public tender procedure. Each software is one possible solution to fulfilling the Building Block Specifications. The selection should not be understood as a recommendation by GovStack.

**Architectural Best Practices**
* Different [Integration Scenarios](https://govstack.gitbook.io/specification/architecture-and-nonfunctional-requirements/6-onboarding) (native and via adapters)
* UI Switching (ID Authentication)

**Reusable and Open Source**
Replicate the Frontend, Backend and Building Block (Emulators) or reuse specific components using our [DYI section](/sandbox/development-17/follow-methodology/diy.md).

Walk Through Steps
1. Click "Log in with e-signet"\ The user gets forwarded to the UI of the *Identity BB*. Demonstrating UI Switching. 2. Click "Log-in here" and enter the ID `9038952310` **to login in as Enrollment Officer** 3. Enter `1 1 1 1 1 1` as One Time Password (OTP) 4. As fictional **Enrollment Officer give consent** to using essential personal information (You do not give consent to use your personal data! It is only for demonstration purposes.)\ The user gets forwarded back to the *Use Case Frontend* with respective role parameters. 5. **Enter the "Candidate Database"**\ The user gets a list of candidates requested by the *Use Case Backend* from the *Registry BB* channeled through the *Information Mediator BB*. 6. **Pick a candidate which has given consent or request consent** to using their personal information by clicking that person and "request consent"\ The user requests information from the *Consent BB*, if candidates approved the usage of their personal data. If approval has not been given yet, the user triggers the *Consent BB* to request approval from the candidate (in this demo, the approval process is mocked and only takes a few seconds). 7. **Enroll any person** to any available benefit package and **log out.**\ The user triggers the *Use Case Backend* to request the *Registry BB* to change the enrollment status of a candidate to "Beneficiary". 8. Repeat the log in procedure with the ID `2405176278` **to log in as Payment Officer**\ Again, the user gets forwarded through the UI of the *Identity BB*. 9. Enter the "Beneficiary Database" and mark (check box) a person to **order payment** 10. Confirm Payment Order\ The user triggers the *Use Case Backend* to request the *Payment BB* to issue a payment order. They *Payment BB* returns successful execution of the payment.
