    • some written updates from flashbots on 4844:
      • for mev-boost it is actively being developed on this branch GitHub - flashbots/mev-boost at develop-deneb. Still dependent on some type upgrades from go-boost-utils but that will be wrapped up soon.
      • builder is still going through 1.12.0 rebase for the upgrade

• open questions / proposals

  • Update mev-boost to call getPayload on all relays (instead of only those which sent the bid)? (mev-boost issue#530)
  • Proposer payment methods - allowing coinbase payments
  • Blind bid selection with zero knowledge proofs
  • change getPayload to not return data to proposer
  • relay funding
  • move validator registrations to blob space?

[metachris]

I’ve got a few additional topics:

1. Update mev-boost to call getPayload on all relays (instead of only those which sent the bid)? (mev-boost issue#530)
2. Proposer payment methods - allowing coinbase payments
3. Blind bid selection with zero knowledge proofs
