All written content on longevitymarbella.com is the original work of Longevity Marbella. We take its integrity seriously, so we protect it in three layered ways and make the proof public.
How this content is protected
- Copyright. The text, structure, and expression of every article are protected by copyright the moment they are created, under Spanish law and the Berne Convention. Reproduction or republication without written permission is prohibited.
- Cryptographic fingerprinting. Each published article has a unique SHA-256 fingerprint recorded in a signed content manifest. Any later change to the text would change its fingerprint, so tampering is detectable.
- Blockchain timestamping. That manifest is anchored to the Bitcoin blockchain using OpenTimestamps, an open, independent standard. This proves the exact content existed, in our possession, on or before its recorded date, with no need to trust us or any single company.
Verify it yourself
You do not have to take our word for any of this. The records are public:
- Download the content manifest: content-manifest.txt
- Download the blockchain timestamp proof: content-manifest.txt.ots
With the free OpenTimestamps tools, ots verify content-manifest.txt.ots confirms the date the content was anchored to Bitcoin, and comparing an article's SHA-256 hash against the manifest confirms the text is unchanged.
Using our content
We are glad for people to read and share links to our articles. What is not permitted is copying, republishing, or repurposing the text without written permission. If you would like to reference or license any of it, please get in touch.
