An open standard
for archiving humanity in DNA.

Memory is the first thing
civilizations lose.

We produce 120 zettabytes of data per year. We can store ~10 % of it. Of what we store, almost nothing will be readable a century from now. The medium itself decays — and the formats become orphaned.

Today, every major DNA storage vendor — Microsoft, Twist, Catalog — uses a different proprietary encoding. A file written by one cannot be read by another. AeonScript is the open standard that fixes this, before the market is captured.

Seven layers,
independently versionable.

Like OSI for networking. Each layer can evolve without breaking the others. The wire format is self-describing — a 2030 reader will still parse a 2230 file, because the file itself declares its codec.

implemented in v0.1 reference codec  ·  planned for v0.2

Encode anything into DNA, right now.

Type a message — or drop an image. AeonScript encodes bytes, not text, so any file works the same way. The L1 + L5 encoder runs locally in your browser — no server, no data leaves this page.

The first message I want to preserve for a thousand years.

# Install
$ pip install -e git+https://github.com/aeonscript-spec/aeonscript@main#subdirectory=reference

# Use
>>> from aeonscript import encode_file, decode_oligos
>>> oligos = encode_file("my_archive.txt")
>>> decode_oligos(oligos) == open("my_archive.txt", "rb").read()
True

Built to outlive its authors.

Where we are.

v0.1 is an early draft. The L1 / L4 / L5 layers are normatively specified and have a working reference implementation. L2 / L3 / L6 / L7 are described at the interface level only. See the roadmap for what's next.
