 ## Builders
 
-Builders can register to receive orderflow from MEV-share matchmakers by submitting a PR to this repository. In the PR, they should add an entry to `registrations.json` with the following information:
+### Criteria for receiving orderflow
+
+To be eligible to receive orderflow, a builder must:
+* Build ≥2% of canonical Ethereum blocks over the trailing 60 days
+* Provide a real-time communication channel for technical coordination
+* Commit to the Flashbots Fair Market Principles
+
+Builders may be suspended if they:
+* Fall below 2% block share over the trailing 30 days; or
+* Violate the Fair Market Principles; or
+* Experience documented technical instability materially affecting inclusion reliability.
+
+In rare cases where these thresholds would impact transaction inclusion for users, Flashbots may temporarily adjust the multiplexing criteria. Any adjustments will be documented and applied equally across all builders.

+### Registering to receive orderflow
+
+Builders can register to receive orderflow by submitting a PR to this repository. In the PR, they should add an entry to `registrations.json` with the following information:
 * Their name as they would like it displayed.
 * The RPC endpoint that matchakers should send bundles to.
 * The API versions they support. Builders can find the complete set of bundle APIs [here](https://github.com/flashbots/mev-share/tree/main/specs/bundles) (version names are indicated by the file name). We recommend that builders upgrade to the latest version when new versions are released. For an example of how to integrate the new `mev_sendBundle` method (and in particular how to enforce validity conditions), you can reference the open-source [Flashbots MEV-Boost Block Builder](https://github.com/flashbots/builder/tree/mev-share).
