How it works

This page is for anyone, with no code and no jargon. If you want the precise mechanics, the Concepts section goes deeper, and Build is for developers.

The problem

When you send money on most blockchains, two things become public forever: how much you sent, and who you sent it to. Anyone can look up your address and see your whole history. They can read your balance, watch your salary arrive, and follow every payment you make. Trading bots use this to get ahead of you. It is the equivalent of every bank transfer you ever make being printed in the newspaper, with your name on it.

The idea

Protocol15 closes that gap. You keep using a normal wallet and make a normal transfer, but you flip on Blind Mode first. With Blind Mode on, two things stay hidden:

• The amount. Outsiders cannot see how much moved.
• The recipient. Outsiders cannot see who received it.

Everyone can still see that a Protocol15 transfer happened. They just cannot read the contents. The name comes from the eye's blind spot: a small patch where you genuinely see nothing, even though the thing is right there.

What it feels like to use

Inside the app there are two clearly labelled layers:

• Normal is your ordinary public wallet, exactly as before.
• Private is the hidden layer: one private balance you can send from, receive into, and cash back out.

You cross between them on purpose. "Make private" moves some funds into the private layer. "Withdraw" moves them back to public. Those two crossings are the only public moments. Everything you do while inside the private layer is hidden.

Sending privately takes two quick approvals in your wallet, and it confirms in seconds. There is no separate app to deposit into, no bridge, and no waiting period.

How you receive

You have a single shareable address, like a username for payments. When someone pays you, the money does not actually land on that address. Your wallet quietly works out a fresh, one-time location for each payment that only you can open. So two payments to you look completely unrelated to anyone watching, and none of them point back to your public identity. Your wallet finds these payments for you automatically.

One important consequence: because only you can open a payment, payments are final. Nobody can reverse one, and sending to a wrong address means the funds are gone, the same as cash. Double-check the address.

Private, but not a black box

Hidden by default does not mean impossible to audit. If you ever need to prove what you did, to an accountant, an auditor, or a counterparty, you can hand that one person a key that reveals exactly what you choose, and nothing more. You stay in control of who sees what. Nobody can force their way in.

In one sentence

You send and receive normally, the amount and the recipient stay private, payments settle in seconds, and you can selectively prove the details later if you ever need to.
