Description
This document proposes a sidecar to
op-node
for requesting block production from an external party.Tests
No tests have been added, but the Software Maintenance section details a path to incorporating in standard OP Stack e2e testing after an initial trial.
Additional context
By decoupling the block construction process from the Sequencer's Execution Engine, operators can tailor transaction sequencing rules without diverging from the standard Optimism Protocol Client. This flexibility allows individual chains to experiment on seqeuncing features, providing a means for differentiation. This minimum viable design also includes a local block production fallback as a training wheel to ensure liveness and network performance in the event of local Block Builder failure.
