[ZIP-16] ZKsync v31 Upgrade

Hey folks - apologies for the slow reply. I was on on leave last week.

The call agenda from July 24th can be found here where it shared the only update for v31 that was available from the engineering team at that time, and linked to the forum post that the update was referencing for people to review directly. There was a technical malfunction with the recording from that day, but a recording of the guest presentation was re-recorded and shared on YouTube.

Proposal Review Discussion Process Recap:

All Proposal Review Calls, which happen every few weeks, are open for anyone to join. This is the core meeting where the ZKsync Association discusses improvements with Delegates, the ZKsync Foundation, operators such as Matter Labs, and ZKsync Chains. The next one is scheduled for Wednesday, June 22nd.

You can subscribe to the Delegate Call Calendar here, and join the ZKsync Delegate Announcements Telegram channel here for Delegate call & other important updates relevant for Delegates.

Proposal Approval Process Recap:

Proposal drafts are posted on the forum under the corresponding draft categories (i.e. Draft ZIPs, Draft TPPs, Draft GAPs). Posting drafts of proposals on the forum is meant to provide visibility for governance stakeholders prior to a proposal being submitted onchain. During this period, partners, security research, community members, and ZKsync Chains are welcome to share comments, insights, and suggestions to the author.

Posting a draft upgrade in the “Draft ZIP” category:

  • does not bind a proposal author in any way — a proposal author is free to edit or update a draft proposal in any way they see fit, over any time period;
  • carries no obligation or timeline requirement to progress the draft proposal to an onchain vote, and
  • is not finalized until it is submitted onchain and formally approved by the Token Assembly, Guardians and then executed by Security Council.

All proposal updates - including new proposal drafts posted on the forum, when they are submitted onchain, start of voting period, voting extension updates, and final voting results - are shared on the ZK Nation X account, as well as the ZKsync Delegate Announcements Telegram channel

You can review the formal ZIP approval process on the ZK Nation docs. You can also visit the docs for detailed information on all ZKsync Governance Procedures, proposal design guidance, and relevant onchain contracts.
