BuilderNet v1.4
BuilderNet v1.4 is the Pectra-ready version of BuilderNet. This release includes newer versions of Reth and Lighthouse, as well as a few minor bug fixes and improvements.
One notable improvement is that TLS certificates for BuilderNet nodes are now persistent, where previously they were rotated on each service restart. This change is part of the ongoing effort to improve the user experience and security of the network.

Reproducible Builds
BuilderNet v1.4 supports fully reproducible TDX image builds. The image you build will produce the exact same TDX measurements as our reference builds.
The main entry point for the image builds is the flashbots/yocto-manifests repository, and for this release specifically the [email protected] (commit 170d166).
To reproducibly build it, clone the repository, check out the tag and build it with Docker/Podman:
git clone https://github.com/flashbots/yocto-manifests.git
cd yocto-manifests
git checkout v1.4.0
make image-buildernet
You can confirm that the hash of your build matches the expected one:
make measurements-buildernet
Build host specs:
- Ubuntu 22.04 x64 (Linux kernel 6.8.0-49-generic), fully updated system
- Intel Xeon Gold 6312U, 48vCPUs, 512GB memory
