I asked frontier AIs the best way to preserve something for *really* long term permanence. Imagine if you can leave your message to future generations, and it will be around for hundreds or even thousands of years. This is a hard problem, but our best possible solution today only costs a few dollars to leave your message!
The answer is exactly why artists are starting to create their Art on Bitcoin. 🧠

Best Digital Permanence for a 400 KB File (Ignoring Cost)
If the sole objective is maximizing the long-term survivability of a 400 KB digital file—and cost is irrelevant—the strongest option available today is to inscribe the entire file directly onto the Bitcoin blockchain.
Why Bitcoin?
Bitcoin offers the strongest known combination of security, decentralization, and economic incentives for long-term data preservation.
- The data is replicated globally. Every archival Bitcoin node stores the blockchain, including inscribed data, creating thousands of independent copies across jurisdictions.
- Exceptional economic security. Bitcoin has the largest and most battle-tested proof-of-work network, giving it the greatest resistance to censorship, tampering, and historical revision.
- Strong incentives for preservation. Bitcoin's primary purpose is to secure a global monetary system, providing continuous economic motivation for participants to maintain and replicate the blockchain.
- Longest operating history. Since launching in 2009, Bitcoin has demonstrated exceptional resilience through market cycles, technical challenges, and geopolitical changes. Its longevity strengthens confidence under the Lindy effect—the idea that technologies that have survived longer are more likely to continue surviving.
Unlike cloud storage or archival services, the file itself becomes part of the blockchain's immutable history rather than existing as an external object referenced by a hash or URL.
A 400 KB file is well within the technical limits for inscription using Bitcoin Ordinals (via Taproot witness data).
Comparison with Other Options
Bitcoin
Best overall choice for maximum digital permanence.
- Highest security and decentralization
- Strongest economic incentives for indefinite replication
- File becomes part of Bitcoin's historical ledger
Ethereum
An excellent long-term platform, but generally a step behind Bitcoin for pure archival permanence.
- Large, decentralized network with strong security
- More complex protocol and a faster pace of evolution
- Greater emphasis on computation and smart contracts rather than serving as the most conservative, immutable ledger
Arweave
Purpose-built for permanent storage and an outstanding archival system.
- Specifically designed to preserve files indefinitely through an endowment-based economic model
- More efficient and less expensive for storing large files
- However, its network, security budget, and adoption are substantially smaller than Bitcoin's, making its very long-term survival more uncertain
Bottom Line
If the question is "Which digital system gives a file the highest likelihood of surviving for centuries, assuming cost doesn't matter?", then inscribing the complete file onto Bitcoin is the strongest answer available today.
No digital medium can guarantee survival forever, but Bitcoin currently provides the most compelling combination of decentralization, security, economic incentives, and global replication for preserving digital information over extremely long time horizons.
