EIP-4844 is almost here, protocol upgrades succeed and more in this week's OP Bulletin!

TL;DR - top 5 of the week

• Introducing RetroPGF rounds with narrow scope

• Superchain Blob Cost Estimator launch

• Protocol upgrades #5 and #6 move to Citizens House

• Round 2 Mission Applications are fast approaching

• OP Goerli will be fully decommissioned tonight

• The OP Stack’s Fault Proof System

EIP-4844 is going live next week and gas fees per transaction are expected to greatly reduce. The Superchain Blob Cost Estimator is meant to give users an idea on how much blobs will save you as a user on OP Stack chains.

Go to welovetheblobs.xyz to check the savings estimator, check estimated savings on one of your previous transactions by accessing Michael’s post on Farcaster or share a link to welovetheblobs.xyz within your cast so others can check their savings inside of your cast.

Estimates are based on different assumptions, learn more about them.

OP Testnets migrate to Sepolia at 22:00 UTC. OP Goerli will no longer be maintained or updated by OP Labs engineers. This is the final day to migrate to OP Sepolia, following the upgrade guide.

The OP Labs’ blog post explores the theory behind the bond mechanism in the OP Stack’s dispute game protocol. The OP Stack's Fault Proof System uses dispute games to achieve decentralized fault detection. These games rely on bonds to encourage honest participation and accurate results.

❗️Voting Cycle #20 Review Period starts today
❗️Citizens' House Cycle #19 Veto Period starts today

Voting Cycle #19 concluded yesterday with Protocol Upgrades #5: Ecotone Network Upgrade and Protocol Upgrades #6: Multi-Chain Prep L1 succeeding. These proposals will move to the Citizens House veto period, wherein any disagreeing Citizen can emit vetoes. 

After passing this period, protocol upgrades would activate March 14th. The Ecotone network upgrade introduces breaking changes for wallets and front-end developers, chain operators, and node operators. Prepare for the upgrade following the documentation.

For the remainder of 2024, RetroPGF will experiment with smaller scoped rounds and pause the execution of broad scoped rounds. Based on learnings of previous rounds with a broad scope, the Optimism Collective hopes this will allow better understanding of what will be rewarded, implement different round design and a overall improved focus.

Round 2 is right around the corner! 
Mission request submission period begins next Thursday, March 14th. Those interested in applying can prepare their submissions by reading the Charmverse and Mission Application Guide.

The author proposes adding private, bribery-resistant, on-chain voting for RetroPGF using MACI, a privacy-focused on-chain voting platform. MACI aims to ensure a secure process, improving transparency and potential for manipulation. You can check out the project’s progress, source code and provide feedback here.
