Set default LocalBlockValueBoost to 10 #13772

I support this change. However, we should likely conduct some testing before merging, considering that local boost has been seldom used. For the reviewer's reference, a similar effort can be found at flashbots/mev-boost#635.

The same type of proposal was submitted as a PR to Lighthouse, Teku, Nimbus and Lodestar: |

Ohh cmon! when we designed this I was aiming for 20 and was voted down that anything above 0 would be controversial, Frederik proposes and it gets insta-approved, I'm jealous... definitely approve of this |
@potuz Sorry! You were right, and I was wrong, just like 99.9% of the other times. @fredriksvantes Do you think we should give this a mention in the ACD? |

yeah, I think that makes sense

Nimbus and Teku merged, cmon ;-) |

I approve the initiative and will approve this PR after the value is applied at the flag level |

Has anyone in this conversation looked at the data or are we just flying blind? A local block value boost of 10% does essentially nothing for censorship resistance. e.g., if we look at the

How do you then boost an external block? With the current setup you cannot as the variable is a uint64 and it does not accept numbers lower then 0. I recommend to actually change this to what lighthouse does which allows you to prioritise local and also external blocks. |
What type of PR is this?

What does this PR do? Why is it needed?
In order to help increase censorship resistance, I propose to change the default LocalBlockValueBoost to 10. This means validators will prioritize local block building unless the bid from the external block builder is 10% or higher than what the validator would receive when building locally.
Looking at stats, it can be seen that currently 63.7% of external builders are censoring transactions compared to 8.53% of validators who do local block building, so setting a minimum 10% as default can help increase the overall censorship resistance of the network.
It is still easy for validators to opt out of this by manually setting the flag to 0, but many are likely to use the default which could help with censorship resistance for the network.
