Engineering a Global Payment System Without the Global Payment Networks

The Problem We Were Actually Solving

Our project, a popular open-source tool for digital creators to sell and deliver their products, had been growing steadily for years. We had a loyal community of users and contributors, but as we expanded into new markets, we hit a wall. The global payment networks we were using, companies like Stripe and PayPal, began to charge us and our users extortionate fees for cross-border transactions. More critically, they restricted access to our store and its features for users from certain countries, citing anti-money laundering and know-your-customer regulations. It was as if our project's global ambition was being slowly strangled.

What We Tried First (And Why It Failed)

Initially, we tried to work around these limits by offering tokenized payment options for users in restricted countries. We partnered with a tokenization service to allow these users to purchase our store's digital products with a locally issued token, which could then be redeemed for the actual product. Sounds good in theory, but in practice, this solution added significant technical and operational overhead for our users and our support team. Moreover, tokenization services also charged us hefty fees, which ate into our profit margins. It soon became clear that tokenization was not a viable long-term solution.

The Architecture Decision

We realized that we needed to decouple our payment system from the global payment networks entirely. We set out to build our own payment system, one that would allow users to purchase digital products directly from our store, without relying on traditional payment providers. We chose to build it using open-source cryptocurrency protocols like Bitcoin and Ethereum, which would allow us to circumvent the restrictive policies of global payment networks. We developed our own payment processing system using blockchain technology, which would enable us to manage transactions securely and transparently.

What The Numbers Said After

After migrating to our new payment system, we noticed a significant reduction in transaction fees for our users. Our own operational costs went down, and our profit margins increased. More importantly, we were able to expand our store's reach to users in countries that were previously restricted by traditional payment networks. Our community grew, and so did our revenue. But what was most striking was the increase in user engagement and retention. Our users were now able to purchase products from our store without the hassle of tokenization or restricted access, leading to a significant boost in our store's conversion rates and average order value.

What I Would Do Differently

Looking back, there are a few things I would do differently. First, I would have started building our own payment system earlier, rather than trying to work around the limitations of traditional payment networks. Second, I would have invested more in user education and support for our new payment system, to ensure a smoother transition for our community. Finally, I would have explored alternative blockchain protocols and services that could have offered us even more flexibility and scalability in our payment processing system. Despite these lessons learned, our decision to build our own payment system has been a game-changer for our project, and I would make it again in a heartbeat.
