Foreverscribe: the facts.
Foreverscribe engraves a short message, up to 80 bytes, on Bitcoin: a dated public record nobody can change, with a certificate to frame, a page to share, and a numbered entry in our public registry. You pay by card in dollars. It isn’t crypto: there’s nothing to buy, hold or trade. Anyone can look up an engraving on Bitcoin, with or without us.
“Twenty-five years, and I would choose you again. — R & M, 2001–2026.”
What it’s for
Short words someone wants kept with a date: a vow, a birthday message, a baby’s first name and birth date, a goodbye, a word they made up.
Each engraving is numbered in our registry in the order it was sent. Its date comes from the Bitcoin block it’s in, which can’t be backdated, and once it’s there nobody, including us, can change a word.
Why Bitcoin
Bitcoin keeps a public record that has added to itself every day since January 2009. Thousands of computers around the world each hold a full copy and check one another, and no single company or government runs it. We think that makes it a good place to keep a few words for a long time.
It also means you don’t have to take our word for it. Every certificate carries a transaction ID: paste it into a public Bitcoin explorer and the message is there, with its block and date (some explorers show it as code; “See it on Bitcoin” on the certificate page decodes it). You don’t need to own any Bitcoin to engrave.
At a glance.
- Price
- $49, everything included, Bitcoin’s fee too. Paid once.
- Payment
- Card, in US dollars. No crypto, wallet or account needed.
- Message
- Up to 80 bytes: about 80 plain letters in English. Accents and emoji take more.
- What’s public
- The message is on Bitcoin. The date and the occasion show on the public page. The certificate’s name fields stay private, on the owner’s certificate only.
- Size on Bitcoin
- One ordinary transaction of about 200 vB, roughly 0.02% of a block. No images or files.
- Proof
- A transaction ID on every certificate, checkable on public Bitcoin explorers or in our registry.
- Ownership
- A private key made in the buyer’s browser is sealed into each engraving. With it, the owner makes proof links anyone can check against Bitcoin, signed twice, once with a post-quantum signature (ML-DSA, NIST FIPS 204). We never see the key.
- Safety
- An automated check reads every message before payment. It can miss things, so people read their own words once more.
What people ask us.
Is Foreverscribe crypto, an NFT or an investment?
No. Foreverscribe issues nothing: no coin, no token, no NFT. There’s nothing to resell and nothing that changes in value. You pay in dollars and get your words on Bitcoin, a link to share and a certificate to frame.
Is putting messages on Bitcoin spam?
Some Bitcoin users feel strongly that the network should carry only payments, and we respect that view. We keep each engraving small: one ordinary transaction, at most 80 bytes of text, and no images or files. That’s about 200 vB, roughly 0.02% of one block, and it pays the going fee to miners like any other transaction.
We use OP_RETURN, the small field Bitcoin’s developers set aside in 2014 so that data people add anyway sits somewhere harmless, out of the list of spendable coins every node keeps in memory. During the 2025–2026 debate over how much that field should allow, proposals ranged from 80 bytes to effectively unlimited. An engraving fits within all of the ones we know of. Besides customer orders, Foreverscribe currently writes two short “dated originals” of its own each day, listed in the registry.
What stops someone engraving something hateful or private?
Every message gets an automated safety check before it can be paid for. It looks for threats, harassment, hate and private details such as a child’s last name, an address or a phone number, and sends messages that are close to the line back to be reworded. Payment only works for the exact text that was checked.
It isn’t perfect. It can miss things, especially in other languages, or names it doesn’t recognize as names. So we also ask everyone to read their words once more before paying, because nothing can be taken off Bitcoin once it’s there.
The names people enter for the certificate (theirs and the person they honor) don’t go on Bitcoin or on our public pages; they’re only on the owner’s certificate, behind a private link. Anything written in the message itself is public.
Is it really forever?
Your words last as long as people keep running Bitcoin, which they have every day since 2009. Nobody can promise more than that. What we can say: no company, including ours, has to stay in business for an engraving to stay readable. If Foreverscribe closed, the transaction ID on the certificate would still open the message on public Bitcoin explorers.
If it’s on Bitcoin, will people actually see it?
Not by accident. Bitcoin is a record, not a feed, and almost nobody browses its raw data. An engraving is seen by the people its owner shares it with, through its page, its certificate and our public registry, where every engraving is numbered and searchable.
What Bitcoin adds is proof, not an audience. Anyone shown an engraving can check, without asking us, that those exact words were written in a particular block on a particular date and haven’t changed since. It works like a land registry or a notary’s stamp: nobody reads them for pleasure, but they settle the question when it matters.
How can I check that an engraving is real?
Paste the transaction ID (or the certificate number) from the certificate into the search on our public registry. It reads the transaction from Bitcoin and tells you whether it’s a Foreverscribe engraving and whether the words match. Or skip us entirely and paste the transaction ID into a public Bitcoin explorer. Many show the message as code (hexadecimal) rather than letters; “See it on Bitcoin” on each certificate page reads the transaction from mempool.space and shows the bytes and the words side by side.
What about Bitcoin’s energy use?
A single engraving doesn’t make Bitcoin use more electricity: miners run the same machines whether a block holds our transaction or someone else’s. It’s one small transaction among hundreds of thousands made every day.
What we hold ourselves to.
- Certificate names stay off Bitcoin. Only the message goes on Bitcoin. The names you enter for the certificate are on your private certificate, not our public pages.
- We ask first. We won’t use someone’s engraving in an ad or a press story without asking them.
- No investment talk. We don’t describe an engraving as an investment or talk about what it might be worth.
- No made-up rush. No countdowns or fake limits on how many we sell.
- We never hold your ownership card. Its key is made in your browser and stays with you. We can’t see it, use it or recover it, and it’s never in our emails.
- Checkable without us. Every engraving can be looked up on Bitcoin whether or not Foreverscribe is around.
- Small on Bitcoin. One ordinary transaction and at most 80 bytes per engraving.
- Help if the site is hard to use. We’re working toward WCAG 2.2 AA. If something gets in your way, write to hello@foreverscribe.com and we’ll help.
For journalists.
Foreverscribe writes short messages into Bitcoin’s public record. Customers pay by card and get a page to share, a certificate to print and a numbered entry in a public registry. Anyone can check an engraving on Bitcoin without us, and no crypto is needed.
