G2: An experience of collective and individual memory, among peers
[very first announcement]
I’m about to share something fragile. Not a promise, not a miracle solution — just a proposal. A space where personal memory and collective memory might, perhaps, begin to breathe differently.
This space is called G2.
What G2 offers — simply
G2 invites you to build and explore trees — genealogical, relational — in 2D and 3D. A few individuals or tens of thousands. With photos, documents, stories. Your history, woven with others’, if you wish.
You can also, if the impulse strikes, connect with others who are exploring their own memorial space. Not to “network.” Not to optimize. Just to meet, exchange, weave.
Your data belongs to you. Period. No central platform, no closed cloud, no invisible intermediary. No fake identities. No Artificial Intelligence coming to harvest what you entrust.
Exchanges happen peer-to-peer. You decide what you share, what you validate, what remains private. For example: some ancestors have no known roots. With G2, you can publish them and expose them to potential matches across the peer-to-peer network — but the inquiry, the caution, the validation, remain entirely your responsibility. It’s a choice: to assume responsibility rather than delegate to an algorithm.
A 3D visualization that isn’t a gimmick
I should say a word about form, because it matters.
The trees in G2 don’t look like what market tools offer. They are rendered in 3D, according to a visualization mode imagined over twenty years ago, and which remains, to my knowledge, unique to this day.
This isn’t stylistic flair. This visual depth allows you to see time: who lived alongside whom, how generations interlock, where ruptures occur. At a glance, you perceive typologies of couples, birth rhythms, multiple unions. And above all: gaps become visible. What we don’t know appears as tears in the graph — invitations to search, to question, to complete.
It’s unprecedented. And I believe it holds many surprises for those who take the time to explore
.Where does G2 come from?
My name is Olivier Auber. I’m a researcher in art and cognitive sciences. G2 didn’t appear overnight. It belongs to a long lineage, both artistic and technical:
In the early 2000s, the “center of disappearance” project and its peer-to-peer 3D Tree, which already explored these questions of memory and representation;
In the 2010s, the principles of the web of trust behind the free currency Ğ1, now implemented by the Duniter software — a radical experiment in peer-to-peer currency, grounded in proof of humanity;
Today, ongoing research (2026) on the transformations of money in the age of Artificial General Intelligence (AGI), within the BGI Nexus group.
G2 is free/libre software. It attempts to carry these ideas gently — at human scale, generation by generation. In its own way, it is an open collective work.
And what about money?
I don’t want to decree anything. But I can’t pretend this project is neutral either.
If we look closely, the way we organize memory — how we connect lives, validate links, share narratives — is not unrelated to how we organize value, trust, mutual recognition.
Money is not merely an economic tool. It is a language. A system of collective memory. And if the structures that carry our genealogical memory evolve — toward more peer-to-peer, more individual sovereignty, more chosen transparency — then perhaps monetary structures, too, can be reimagined.
I’m not saying G2 will revolutionize money. I’m saying it opens a space where this question can, gently, emerge. Where we can experiment, at small scale, with what a memory-based economy might look like — grounded in verifiable trust, reciprocity, and respect for human time.
It’s experimental. Truly.
I won’t hide the uncertainties. G2 is in its initial version. There will be bugs, limitations, things to reinvent. I’m not trying to convince, but to invite: those who feel that memory deserves better than closed silos, that human connections deserve better than optimization algorithms, that technology can serve something other than extraction.
If this proposal resonates with you, you are welcome to explore, test, critique, contribute.
G2 is not an arrival. It’s a departure — modest, attentive, generation by generation.
By humans, for humans.

G2 will soon be available in experimental version. Free/libre software, peer-to-peer, no data collection. If you want to be among the first to try it, like this post and leave a comment. Thanks!
