Anyone with stories worth keeping. What you remember of your parents. What you want your kids to know. The advice you wish someone had given you at 22.
Legacy
Everything you say lives on someone else’s server. The Tower puts it somewhere that outlasts you, outlasts us, and outlasts the company that owns the server.
Start your legacy →Anyone with stories worth keeping. What you remember of your parents. What you want your kids to know. The advice you wish someone had given you at 22.
Founders + builders. Why you started. What you saw that nobody else did. The note you’d leave for whoever inherits the company in 30 years.
Academics + researchers. Work that may not be recognized in your lifetime. The mathematical conjecture, the falsified prediction, the dataset you haven’t had time to publish.
Anyone facing illness. Words you want to survive you. A letter to your child for an anniversary they’ll have without you.
Artists + writers. Drafts dated for posterity. The version that came before the published one. The first time you wrote the line that became famous.
Quiet rebels. The dissent you couldn’t voice publicly at the time. The truth you needed to record before the moment passed.
Open — visible on your dashboard, public to anyone with the hash. Free first, then $2. Best for things you want findable.
Sealed — encrypted in your browser with a key only you hold. Even we can’t read it. $5. Best for things only specific people should ever see.
Time Capsule — auto-unlocks and emails you (or whoever you choose to share the link with) on a date you pick. $10. Best for letters to a future moment.
Bitcoin has run continuously since 2009. Its ledger is replicated across thousands of independent nodes worldwide. No company owns it. No government has successfully shut it down. No CEO can pull the plug. As long as anyone, anywhere, runs a Bitcoin node, the hash you anchored today remains mathematically verifiable. The Tower is one tool that puts your declaration on that chain. Hundreds of other tools, including standalone scripts, can verify what you put there — even after The Tower is gone.
We recommend downloading your proof receipt at carve time. It’s a small file that contains everything needed to verify your timestamp — with or without The Tower running.
It means: in 2076, someone holding your written words can prove you wrote them in 2026. Not because a company says so. Not because a notary’s seal hasn’t faded. Because the math doesn’t lie and the Bitcoin block is still there.
Most things people write disappear within a generation. Letters get lost. Hard drives fail. Cloud accounts get closed for non-payment after the holder dies. The Tower is for the words you don’t want to lose to any of that.
Your first Open carve is free.
