Grin
Two problems show up on many well-known digital-money networks. First, the public shared record shows how much each payment was. Second, anyone keeping a full copy of that record watches it grow and grow, because past payments stay listed with their amounts in plain sight.
Grin is online money meant to ease both issues. Observers looking at the public record cannot read the size of each payment. The way the data fits together also means the stored history can stay lighter than on systems that replay every old amount. Many machines compete to seal new payments into the shared record; Grin’s project site walks through how that works.
Tradeoff: one-tap bank apps often finish after a single send. Grin usually needs your app and the other person’s app to trade a few rounds before the payment is done. That is part of how the design achieves the goals above.
Things to watch for
- Fewer places to buy or sell than the best-known digital money. If you use a site that sells digital money, confirm it lists Grin, what cash-out costs, and which option to choose so funds are not stuck.
- Downloads and messages you did not ask for can empty your balance. Only install software from sources you trust, and read every screen before you confirm a payment.

FAQ
- What is Grin?
- On many digital-money systems, anyone can open the shared public record and see **how much** went with each payment. Over the years, a full copy of that record also gets **very large**, because **every old payment stays written out in the open**. Grin is a different design aimed at those two headaches: the public record **does not reveal payment sizes**, and **the data people store to stay in sync can stay smaller** than on those older-style networks. You hold and move it with **software built for Grin**. The cost is practical: **a send often needs several back-and-forth steps** between your app and the other person’s before the payment clears.
- Can strangers see how much I sent?
- Not from the open payment list by itself, the way they often can with **bitcoin**. How you cash in or out, or what company’s app you used, can still leave a trail outside that list.
- Why is paying someone harder than with my usual app?
- Bank-style apps often send after one tap once you pick a payee. Grin usually has your app and the other person’s app exchange a few steps before the payment finishes. Read Grin’s official help before you try a real payment.
- Is Grin safe?
- Digital money always carries risk: scams, fake downloads, typos, and sites that stop working. Grin is harder to buy or sell than the best-known digital money because fewer people use it. Read Grin’s beginner material; do not risk money you need for living expenses.
- Is this financial advice?
- No. This content is general education only.
