Archived Networks
The Mesa test networks on this page are archived: they are no longer running, their builds are no longer supported, and the versions listed are historical. They are kept here as a reference for operators tracing old logs, images, or package pins.
For all current testing, use Mesa Trail.
Preflight
An early Mesa test network, used to validate the upgrade before Mesa Trail.
| Field | Value |
|---|---|
| Pre-fork release | 4.0.0-preflight1-b649c79 |
| Stop-slot release | 4.0.0-preflight-stop-2967b39 |
| Post-fork (Mesa) release | 4.0.0-preflight-3f038cb |
| Hard-fork time (UTC) | 2026-04-27 13:00 |
| Transaction protocol version after fork | 5.0.0 |
| o1js version targeting protocol v5.0.0 | o1js@3.0.0-mesa.698ca |
| Docker tag suffix | -mesa (for example mina-daemon:4.0.0-preflight-3f038cb-bookworm-mesa) |
| Debian channel | preflight on unstable.apt.packages.minaprotocol.com |
| Debian packages | mina-mesa, mina-archive-mesa, mina-rosetta-mesa |
| Seed nodes | seed-1.mina-mesa-network.gcp.o1test.net, seed-2.mina-mesa-network.gcp.o1test.net |
The preflight fork-schedule values are also recorded on the Fork Schedule page.
MUT
The MUT network (mesa-mut) was a Mesa upgrade-test network that exercised the full stop-slot → fork → post-fork sequence on 4.0.0-rc1 builds. Operator feedback from MUT fed directly into the upgrade procedures documented in these pages.
| Field | Value |
|---|---|
| Releases | 4.0.0-rc1 builds (for example 4.0.0-rc1-83b4654, 4.0.0-rc1-mesa-mut-d7513d4) |
| Docker tag suffix | -mesa-mut (for example mina-daemon:4.0.0-rc1-83b4654-bullseye-mesa-mut) |
| Seed nodes | seed-1.mesa-mut.minaprotocol.com, seed-2.mesa-mut.minaprotocol.com |
