# Preservation

> Where the text of the Urantia Papers is stored: a blockchain archive, the Internet Archive, and public repositories.

The English text of the Urantia Papers is stored in three independent places, so no single service can remove it.

## Strategy

Our preservation approach has three layers:

| Layer | Purpose | Status |
| - | - | - |
| **Blockchain (Arweave)** | Immutable, decentralized permanent storage | ✅ Live |
| **Internet Archive** | Timestamped third-party institutional archive | ✅ Live |
| **Public GitHub** | Open-source, forkable, version-controlled | ✅ Live |

Each layer serves a different purpose, and each one works without the others.

## Blockchain Archive (Arweave)

The complete English text is permanently stored on [Arweave](https://www.arweave.org/), a blockchain designed for multi-century data persistence. Once written, content cannot be altered or removed.

Two formats are archived:

| Format | Arweave Transaction ID |
| - | - |
| Structured JSON | [`3RLvenzfBZ60GlOygqu6DtlbEhOWldQSqjGuMSVOg9I`](https://arweave.net/3RLvenzfBZ60GlOygqu6DtlbEhOWldQSqjGuMSVOg9I) |
| Plain Text | [`0YgTs2SJmIkCHxouFPdN-pWFon0ZnhjYQpg7F2DW70o`](https://arweave.net/0YgTs2SJmIkCHxouFPdN-pWFon0ZnhjYQpg7F2DW70o) |

<Tip>
  You can access these through any Arweave gateway. The transaction IDs are permanent.
</Tip>

**Why Arweave?**

* **Immutability:** content cannot be altered once stored
* **Decentralization:** no single point of failure
* **Permanence:** data persists as long as the network exists
* **Verifiability:** anyone can independently verify the content using the transaction IDs

## Internet Archive

The complete English text (197 papers, 14,500+ paragraphs) in structured JSON format is archived on the Internet Archive:

<Card title="Urantia Papers on Internet Archive" icon="building-columns" href="https://archive.org/details/urantia-papers-english-json-2026">
  Timestamped, institutionally preserved copy with CC0 license. 202 JSON files covering the full text.
</Card>

The Internet Archive has been preserving digital content since 1996 and provides an independent, institutionally backed copy that doesn't depend on us.

## Public GitHub Repositories

All source data, code, and documentation live in public repositories under the [urantia-hub](https://github.com/urantia-hub) GitHub organization.

The data pipeline:

<Card title="urantia-hub/urantia-data-sources" icon="github" href="https://github.com/urantia-hub/urantia-data-sources">
  Scripts and manifests for the published data: papers, audio, entities, and embeddings.
</Card>

GitHub provides version history, forkability (anyone can copy the entire repo with one click), and global CDN distribution. Every repo includes a `LICENSE` file and disclaimer.

## OpenTimestamps (Bitcoin-Anchored Proofs)

All MIT license files and the root `LEGAL.md` have been timestamped using [OpenTimestamps](https://opentimestamps.org/), which anchors SHA-256 file hashes to Bitcoin transactions.

This creates cryptographic proof that our license dedications and legal declarations existed on or before a specific date. All 13 proofs have been upgraded with full Bitcoin attestations and are independently verifiable offline.

| File | SHA-256 Hash |
| - | - |
| All `LICENSE` files (12 repos) | `0f880bee4323620b11a287c6ccf7013610e064d0a4943c25f398c149b32d8fa7` |
| `LEGAL.md` | Timestamped separately (CC0 dedication, trademark policy, non-affiliation) |

Proof files (`.ots`) are stored alongside their source files in each repository. Verify with:

```bash theme={null}
ots verify LICENSE.ots
ots verify LEGAL.md.ots
```
