BuilderNet v1.6 is a major release focused on consolidation, performance, and protocol readiness. This update brings a ground-up rewrite of our orderflow ingestion layer, merges rbuilder-operator into the main rbuilder codebase, and adds full support for the upcoming Fusaka hardfork.

BuilderNet v1.5 introduces EVM caching, an (even) faster root hash, and trusted TLS certificates to improve the security and experience of submitting orderflow.

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.

Beaverbuild is retiring their centralized block builder to work full time on BuilderNet, a decentralized mempool and block building platform for Ethereum.

BuilderNet v1.3 is the culmination of close collaboration with searchers, OFAs, and other orderflow providers to integrate BuilderNet directly with their production workflows. This release improves both the user experience for sending bundles to BuilderNet nodes, and the testing, observability, and deployment experience for operators to facilitate faster iteration in the future.

We are excited to release BuilderNet v1.2, a significant upgrade that streamlines operator onboarding and enhances the security and performance of the BuilderNet infrastructure.
