**Founder, CEO & CTO of [Samouraï Coop](https://www.samourai.world)**, a worker cooperative from Paris that is a film crew and an engineering studio in one company, building and promoting open-source culture since 2016.
Co-founder of the [Paris P2P Festival](https://p2p.samourai.tv). For more than 12 years I've worked across the peer-to-peer, cybersecurity and open-source ecosystems, researching and building decentralized organizations. Alongside the coop, I lead **samcrew**, our gno.land team: core contributors to GnoVM and the gno.land chain, and one of its genesis validators. I also build [Memba](https://memba.samourai.app).

</gno-columns>
## 今 Now
- **Holding the line.** samcrew runs one of the four validators securing `gnoland-1`, live since mainnet launch on 12 September 2026.
- **Memba, on mainnet.** 14 samcrew packages are live, from the [App Store](/r/samcrew/memba_appstore_v3) to [escrow](/r/samcrew/escrow_v3) and an [arcade leaderboard](/r/samcrew/memba_arcade_leaderboard_v1).
- **Filming the chain.** The crew keeps documenting gno.land: retreats, events, builders.
## 道 Four years in the gno.land core
Samouraï Coop has contributed to the gno.land core for more than four years. The crew has **[256 merged pull requests in gnolang/gno](https://github.com/gnolang/gno/pulls?q=is%3Apr+is%3Amerged+author%3Aomarsy+author%3AVillaquiranm+author%3Amvallenet+author%3Adavd-gzl+author%3An0izn0iz+author%3Ahthieu1110+author%3Amoonia+author%3AWaDadidou+author%3Aomniwired+author%3AAmozPay)**, about one in eleven of every PR ever merged there, and more each year: 48 in 2024, 79 in 2025, 128 so far in 2026.
| | what we do |
| --- | --- |
| **GnoVM** | The interpreter, its type checker, stdlibs and test suite: most of our upstream work. |
| **Security** | Hardening the VM, consensus and p2p against crashes, overflows and malformed input. |
| **Chain & tooling** | gno.land node, tm2, genesis tools, `gnodev`, docs. |
| **Validators** | A genesis validator, [gnomonitoring](https://github.com/samouraiworld/gnomonitoring) and the [katana](https://github.com/samouraiworld/katana) GovDAO daemon. |
| **Governance research** | Our [research lab](https://samouraiworld.github.io/gov-research-wiki/) studies how cooperatives, DAOs and open-source projects govern themselves. [gnodaokit](https://github.com/samouraiworld/gnodaokit) and Memba are its output. |
| **Design partner** | We build our own products on gno.land and send what they teach us back upstream. |
| **Documentation** | Retreat and event reports for the core team, the Peer Dev tutorials, the WEB TRIP interviews. |

## 組 Inside Memba
[Memba](https://memba.samourai.app) is an experimental operating system for decentralised organisations, and the direct output of our governance research. It is MIT-licensed and [open source](https://github.com/samouraiworld/memba). Each of its parts is a product in its own right. Hover a card for details.
Every game uses one daily seed for everyone, drawn from a gno.land block, and needs no wallet.

## 祭 Events
We produce the events we believe in, and we film the rest of the ecosystem's. **Paris P2P Festival**: five days of peer-to-peer at Ground Control, free, for 5,000 people. The Édition #1 talks are [all online](https://p2p.samourai.tv). **Hyper Hacktive Festival**: a film festival for independent documentaries funded by Samouraï Grants. It has had three editions, two at mk2 Quai de Seine, and sells its tickets on Zenao.
