## Educational Value / Outcomes Delivered (Summary)

Ringkasan nilai edukasi yang diterima dari sesi ini (berdasarkan handout yang dibagikan kepada peserta):

### What You'll Learn

* Memetakan opsi pembayaran lintas negara dengan kesadaran biaya & latency.
* Menjelaskan cara kerja escrow dan kapan memakai smart contract.
* Memahami dasar kepatuhan (KYC/AML & pajak) untuk konteks kampus/startup.
* Menggambar arsitektur minimal dari Web2 → Web3 payments.
* Menentukan langkah lanjut (workshop praktik & capstone clinic).

### Quick Comparison

* **Bank/Fintech rails:** mapan, biaya overhead lebih tinggi, potensi chargebacks.
* **Stablecoins (mis. USDC):** settlement lebih cepat, biaya lebih rendah, programmable; membutuhkan on/off-ramp sesuai KYC yurisdiksi.

### Pragmatic Escrow

* Pakai perantara tradisional untuk kasus sederhana.
* Pakai **smart-contract escrow** saat butuh otomatisasi & rilis berbasis milestone.
* Selalu definisikan jalur sengketa & time-lock; mitigasi risiko kunci & bug.

### Next Steps (Students)

* **Workshop 3 jam (diskon kampus)** — latihan alur pembayaran global + escrow.
* **Capstone Clinic (6 tim, 2×60’)** — bimbingan tugas akhir/proyek.
* **Research internship (selektif)** — riset rails & escrow.\
