Meeting Summary:

The meeting focused on updates and discussions related to DevNet 8 and EIP 7610. Stefan provided a status update on DevNet 8, mentioning a blog post, the upcoming GLOS upgrade, and testing plans for builder deposits and client software. Ahmad raised a question about the contributor program, which was acknowledged by Parithosh. The main discussion in the EL breakout was about EIP 7610, where Gary and Dragan expressed that the EIP was not necessary and could be removed from the Amsterdam fork. Jochem-Brouwer agreed with this assessment, noting that removing the EIP would allow clients to pass canonical tests. The group decided to remove EIP 7610 from Amsterdam, with Jochem-Brouwer planning to document the decision. The conversation ended shortly after this discussion.

Stefan provided an update on Lambton DevNet 8, announcing that a blog post and tweet have been published about the testnet. He mentioned that DevNet 7 will likely be sunset when DevNet 8 transitions to GLOASS, and noted that Luca Sanolini’s PR should address consensus-breaking issues if implemented quickly enough. Stefan also shared a GitHub link to the relevant pull request for further details.

Justin and Stefan discussed the upcoming GLOS upgrade scheduled for 2 days and 17 hours later. They reviewed testing plans, including builder deposits and software testing, with specific views and resources shared for monitoring deposits and builder indexing. Stefan mentioned that they would not be testing the SC side on DevNet 8 but would do so later on FT DevNets, and a list of testing focuses was shared for review.

Ahmad inquired about the best way to get re-enrolled in the contributor program, as the previous registration method using standoffs appears to have been deprecated. Parithosh indicated that Andrew or Sam would review Ahmad’s request, as some team members were on vacation.

Justin led a brief meeting regarding DevNet 8, noting there were no combined discussions planned between CL and EL groups on the agenda. He shared a Zoom link for the CL breakout call and indicated it would be a quick meeting. The EL group was instructed to continue their discussion with one agenda item remaining.

The team discussed removing EIP 7610 from the Amsterdam fork due to concerns about hash collision security implications. Gary and Dragan Rakita agreed that including this EIP was not necessary as it targeted a specific edge case that could be addressed through EIP 8253 by bumping nonces for the affected accounts. Jochem Brouwer decided to raise this decision at the All Core Developers (ACDC) meeting, noting that removing the EIP would allow clients to pass canonical tests and would not change any existing behavior.

Next Steps:

  • Stefan: Share the blog post and tweet links for Lambton DevNet 8 in the chat.
  • Stefan: Share the notes containing the list of testing focuses for DevNet 8.
  • Justin: Review the shared notes and list of testing focuses for DevNet 8 after the call.
  • Parithosh: Ensure that Andrew or Sam look at Ahmad’s request regarding re-enrollment in the contributor program.
  • jochem-brouwer: Draft and publish a decision in one and a half weeks to remove EIP 7610 from the Amsterdam fork, clearly messaging that this is not a behavioral change and referencing the discussion.
