Blockchain Small Business Series Part 1 | 5 min read
Has this ever happened to you?
You sold something to an overseas buyer and watched 5% disappear in fees. You delivered a project and waited 90 days to get paid. You hired a freelancer, got the work, and then heard “that wasn’t the agreement.”
These three scenarios cut across industries. And here’s the frustrating part: Toss, KakaoPay, your bank, your card company — none of them fundamentally solve any of these problems.
Why not? That’s what this article is about.
Picture a seller who runs an Instagram shop with buyers in Japan and the US.
PayPal charges 4.4% plus a fixed fee. Add 2–3% in foreign exchange spread. That’s 6–7% of every sale gone before you’ve covered a single cost.
On 5 million KRW in monthly sales, that’s 300,000–350,000 KRW in fees. Per month. Over a year, that’s the equivalent of a month’s salary for a part-time employee.
Toss isn’t fixing this — not because of a technology gap, but because of international financial licensing. The moment a transaction crosses a border, Toss’s jurisdiction ends.
Small suppliers, interior contractors, food distributors. They share a common reality.
Goods delivered today. Payment in 30, 60, or 90 days.
During that window, materials and labor come out of your pocket. If you can’t wait, you turn to invoice factoring — and pay 3–8% in fees just to access money that’s already yours.
Toss Bank offers revenue-backed loans, but that’s not a solution to the net terms problem. It’s a way to survive on debt while the real problem remains.
You hired a designer. You agreed over KakaoTalk: three logo concepts, two rounds of revisions, 300,000 KRW. You asked for a revision. They said that’s extra.
Or the reverse — you delivered the work and the client says the terms were different, and delays payment.
Platforms like Kmong and Freemoa handle some of this, but charge 15–20% in commissions. And any contract made outside a platform still lives in a KakaoTalk screenshot — which can be disputed.
All three leaks share the same root cause: the cost of establishing trust between strangers.
Until now, reducing that trust cost meant bringing in a larger intermediary — a bank, a platform, a court. And intermediaries always take a cut.
In Part 2, we look at a technology that removes the trust cost without a middleman. It’s called blockchain timestamping, and it works by recording your contracts on the Bitcoin network — permanently, at a cost of a few hundred won per document.
Spoiler: it won’t solve everything. But for one of these three leaks, it changes the math completely.
If this series is useful, follow along — Part 2 is coming next week.
