## EPF Week 6 Updates Recently, I had a conversation with lighthouse about delayed execution, and their stance is that since [eip-7732](https://eips.ethereum.org/EIPS/eip-7732), epbs, is likely to go into Glamsterdam, my efforts would be better used to aid them in building out epbs. The headliner decision for the hard fork will be August 7th, but almost all signals point towards eip-7732. Since the whole point of the EPF program is to provide an opportunity towards long-term core dev work, it seems like an obvious choice to take lighthouse up on their offer to help out. A nice article on the pros and cons of delayed execution verses epbs are laid out [here](https://notes.ethereum.org/@0YxgBRfbR0OTJbu2fDpY2Q/BkyjpOJEgg?utm_source=preview-mode&utm_medium=rec). In a nutshell, you get the same execution block size scaling benefits via epbs as you do in delayed execution but additional wins like trustless payments between block builders and proposers + much more time to propagate blobs. After diving pretty heavily into the epbs specs, I can see how the aforementioned benefits align with Ethereum's pillars of scaling the base layer and expanding blob capacity. At it's core, epbs splits a consensus block from an execution payload, which lends naturally to the separation we have today between the CL and EL. It's pretty exciting, the more you look into it! This week, I have started implmenting new `EthSpec` constants and new containers per epbs [consensus spec](https://ethereum.github.io/consensus-specs/specs/_features/eip7732/beacon-chain/#eip-7732-the-beacon-chain) in [PR](https://github.com/shane-moore/lighthouse-eip-7732/pull/1): - `Constants > Domain types` - `Preset > Misc + Max Operations per block` - `Containers` - `PayloadAttestationData` - `PayloadAttestation` - `PayloadAttestationMessage` - `IndexedPayloadAttestation` - `ExecutionPayloadEnvelope` - `SignedExecutionPayloadEnvelope` For delayed execution, I also made a significant amount of header updates to lighthouse, which provided good practice learning the structure and flow of their repo, [PR](https://github.com/shane-moore/lighthouse-eip-7732/pull/3) ## Next week - update project proposal to epbs - build out more of the epbs spec
