Meeting Summary:

The team held their first EncryptoMempool kickoff call to discuss the implementation of two EIPs, with participants focusing on project management aspects and design updates. The discussion centered around gas pricing mechanisms, transaction ordering, and potential security considerations for both the 8105 and Lucid projects. The team identified areas requiring further research, including bundle detection and its implications for public encrypted mempool designs, with plans to continue discussions in their next meeting.

The team held their first EncryptoMempool kickoff call to discuss the implementation of two EIPs (8105 and Lucid). Justin emphasized the need for regular attendance from both the 8105 and Lucid teams, with Jannik confirming the schedule worked for him. The meeting focused on project management aspects, with participants already familiar with the designs, and Justin noted that the recordings would be posted on YouTube.

Jannik presented updates on their EIP, focusing on a new two-slot execution design with encrypted and decrypted transactions. They explained the changes made to prevent envelope stripping attacks and discussed gas reservation between the two slots. Justin inquired about the gas pricing mechanism, suggesting potential approaches like fixed markups or overhead costs for reserving next block’s gas. The discussion highlighted the need to address gas pricing challenges in both designs, considering the potential changes in base fee and its impact on execution gas metering.

The team discussed gas pricing and transaction ordering in blockchains, focusing on sealed transactions and inclusion lists. They explored potential abuses and incentives for builders, concluding that while there are some considerations, the system appears relatively safe. Jannik suggested researching real-world data to understand the impact of transaction ordering on gas usage and execution results. The team also briefly touched on the status of the Lucid project, noting that work on IP is ongoing.

The team discussed the need to investigate bundle detection and its implications for public encrypted mempool designs. Justin suggested writing down the problem more clearly and reaching out to analysts or meta searchers for help with simulations. They also touched on the possibility of adding bundle functionality to a minimal design for an EIP, but decided to research it further before their next meeting. Justin agreed to open a GitHub issue for agenda items for the next call in two weeks.

Next Steps:

  • Jannik: Review the gas pricing issue between two-slot design and compare with Lucid proposal, make updates to 8105 proposal if needed
  • Anders: Complete work on Lucid EIP (will take a few more days to get something up)
  • Jannik: Try to analyze old blocks by shuffling transactions to see if execution outcomes remain similar (if resources allow), and report findings at next call
  • All participants: Reach out to personal networks to find analysts or meta searchers willing to help with bundle detection and simulation research
  • Justin or Jannik: Write down and clearly outline the bundle ordering problem, give it a name for better discussion
  • Justin: Open a GitHub issue for posting agenda topics for the next call
