The first thing written for them.
Written today, for when they can read it.
Baby books get lost in moves. A few words on Bitcoin stay put, with the date, for as long as Bitcoin runs.
Write them a line, engrave it, and frame the certificate for the nursery. Grandparents like this one too.

A certificate to keep, and a line that can’t be lost.
- A certificate to frame. A PDF for Letter, A4 or 11×14, printed at home or at any print shop.
- A page to share. One link that opens on any phone, for everyone who should see it.
- A permanent record. The line itself on Bitcoin, with its date, checkable by anyone, with or without us.
- Signed by you. The certificate carries the name on the card that pays, and theirs in “In honor of”.
Ways to give it.
You sign the certificate with the name on your card; the baby goes in “In honor of”. A first name and the date are plenty in the line.
From the parents
Frame the certificate for the nursery; send the link to the family.
“Ava, born May 2, 2026. You were worth every 3 a.m. Love, Mom & Dad”
From the grandparents
You sign it as the giver. Bring the framed certificate on your first visit.
“Welcome, Theo. Grandma and Grandpa waited a long time for you.”
A baby-shower gift
It takes no room in a small apartment: a frame, or just a link.
“Little one, the world got better the day you arrived. — Aunt Kate”
First lines.
“Theodore, born August 9, 2026. Welcome to the world, little one.”
“Hi Ava. You were worth every 3 a.m. Love, Mom & Dad, 2026”
“For June, our first grandbaby. We started spoiling you today.”
How it’s kept.
01Write them a line
Up to 80 plain letters, about one sentence. A first name and the date are plenty. Leave out last names, places and anything that could help a stranger find your child.
02It joins the next block
About every ten minutes Bitcoin adds a block, stamped with the time. Your words usually go into the next one, and that’s their date.
03Frame it
A certificate to print for the nursery wall, and a link for family. The transaction ID opens the words on a public Bitcoin explorer.
- 10:09
- 10:21
- 10:31Their line
- 10:42
- 10:50
Public for good, so keep it light.
Your child didn’t get a say, so write what you’d be happy for them to find at sixteen. Full names stay off Bitcoin, on a certificate only people with your private link can open.
Public anyone can see it
Birth Record
“Theodore, born August 9, 2026. Welcome to the world, little one.”
These words go on Bitcoin, for good.
Private only via your link
- Signed byAnna Brooks
- In honor ofTheodore Brooks
- Emailanna@example.com
What it proves, and what it isn’t.
It proves
- These words were written by that date
- Nobody has changed a letter since
- They don’t depend on us, or any website, staying around
What it isn’t
- A birth certificate or any official record
- Private: anyone can read the words
Birth certificates come from the state. This is a keepsake.
Good to know.
A first name and the date are plenty. Skip last names, the hospital, the town and the birth time together, since that’s the kind of detail that helps a stranger find a child. The full names on your certificate aren’t on Bitcoin or the public page.
Yes. For now the certificate is signed with the name on the card that pays. Forward the private link from the order email to the parents, and they can print and frame it.
No. Nobody can take it off Bitcoin, us included. That’s the reason to keep it to a few warm words they won’t mind.
Nobody can promise forever. Bitcoin has added blocks every day since 2009 and is copied on thousands of computers, and as long as it keeps running the words stay put.
No. It’s a dated public keepsake. Birth certificates come from the state.
$49, paid once by card, everything included, Bitcoin’s fee too. You get a link to share and a certificate to print and frame.
Say hello, for good.
Write their line, pay by card. It usually goes into Bitcoin’s next block, about ten minutes later.
