Three words. Yours forever.
Your three-word handle, poem, message or mantra. A friend confirms you're human, and it's yours — free for life.
Your EchoStamp — it changes as you type.

How it works
- 1Pick your three words
Type them at the top. If nobody has them yet, they're yours to claim. It's free.
- 2A friend confirms it's really you
You get a link to send them. They tap it and confirm in a minute. We call this witnessing. Gimoku adds the second confirmation, so one friend is all you need.
- 3It's sealed on Bitcoin, forever
Your echo is written into Bitcoin — the most permanent public record there is. Once it's there, it can't be changed.
this is what yours becomes
Why does a friend need to confirm it?
Anyone can grab a username — including bots. An echo only counts once a real person confirms it belongs to you. That's what makes it impossible to fake.
Help others, and your EchoStamp levels up.
Your three words never change. But the more echoes you confirm for other people, the higher your EchoStamp climbs — graphite, steel, bronze, silver, gold, all the way to Crown.
Check it yourself
You don't have to take our word for it. Echoes are recorded on Bitcoin in batches of 1,000, called Gimoku Blocks, so recording stays free. Anyone can look up a block and see the echoes inside it.
