So our independent work at Project Timestamper has been to digitally timestamp these 86 million individual recorded tracks to anchor their authenticity. We embedded these timestamps on the Bitcoin blockchain using the OpenTimestamps service. The timestamps provide permanent cryptographically verifiable proof that these music tracks existed at the end of 2025, before AI content has come to dominate.

We ourselves aren’t storing any content: we are focusing narrowly on archiving the timestamp proofs, just as we have done for millions of books, films, paintings, and research papers that exist today in digital form somewhere on the Internet.

So if you love music, or culture, or science and you want to help us with timestamping, please reach out!

We'd like to continue to expand Project Timestamper and could use your help!

If you would like to participate in this project, we'd love to hear from you.

And please share with anyone you think might be interested. 🙏

- What will future threats to cryptography, blockchains, and authenticity look like?
- How can we make sure our timestamps are available, discoverable and unforgeable long after we are gone?

7/🧵

In this work, we have been facing such questions as:
- What counts as important human work?
- Where are the most valuable cultural, scientific, and historic collections?
- How can we scale up this project to timestamp more of human culture?

6/🧵

We believe there is an urgent need to draw a clear line between human cultural heritage and AI counterfeiting, before it's too late.

5/🧵

Each file is hashed (such as with SHA-256) and a timestamp is created, anchored in the Bitcoin blockchain.

This creates a public, durable and tamper-resistant record of the artifact’s existence at a specific moment in time.

4/🧵

http://ProjectTimestamper.org is an independent, open-source effort we have recently launched to help protect human cultural memory by locking in the integrity of important human cultural and scientific works.

3/🧵

If AI can make fake historical cultural artifacts, how will future generations of humans know what humanity achieved in the past?

How will human values, human culture and knowledge of human science and history survive in a post-truth world?
