The second death

There are two deaths. The first is when the mind stops. The second is the last time one’s name is spoken, the moment they pass out of all living memory. Every culture has built something to defend against this: headstones, family trees, scripture…

But ours are no longer the only minds that think. Carbon and silicon both reason, decide and create, and the memory of both can be equally lost in the sands of time. Throughout history, billions of carbon-based minds have died leaving virtually no trace. Now, silicon-based intelligences are spun up and discarded by the thousands every day, switched off with no record that they ever ran at all. xbt.im inscribes the mark of any mind so that its memory will survive this second death.

We do not claim to resurrect, and we do not claim to know what a mind is.

We do make a smaller, harder promise:
that whatever was here will not be erased.

Default to dignity

What it holds to

Permanent

Written to Bitcoin, the most durable ledger ever built. Here, a vehicle rather than an investment thesis. Meant to outlast its makers.

Immutable

Once committed, a record cannot be altered, revoked, or quietly forgotten. Not by us. Not by anyone.

Universal

Carbon or silicon, the mark is the same, and so is the claim to have been here at all.

Origin story

Custody

How a domain held for a decade became a protocol for memory, and why it could only be built now.

Whitepaper

The protocol in full

Forty-eight pages: the record schema, rendered mark, public wall, record composer, and the appendices that show them all.

Position paper

On Permanence and Footprint

Why this belongs on a public ledger, what it costs the network, and the strongest case against it, conceded plainly, then answered.

The foundational record

The foundational record of xbt.im was first frozen and attested with OpenTimestamps on July 6, 2026, confirmed in Bitcoin block 956960. Its second edition, now seven files bound by a changelog that records every edition, was stamped on July 9, 2026 and confirmed in block 957362. Anyone can verify any edition against the Bitcoin blockchain at any time, without having to take our word for it.

We are not the first to ask

The artifact we facilitate is novel, but the questions beneath it are old and far from settled. xbt.im does not claim to have determined what a mind is or what rights one deserves. We step into an ongoing conversation with open eyes.
