🔒 Scroll Upgrades zkVM Security with OpenVM v1.6.0
🔐 Scroll patches zkVM
Scroll is upgrading its zkVM prover stack from OpenVM v1.4.1 to v1.6.0, a focused security maintenance update addressing critical soundness issues.
Key improvements:
- STARK now targets 100 bits of provable security with FRI
- RV32IM VM extension formally verified in Lean
- Fixes for under-constrained SHA-256/Keccak circuits
- Missing pairing-check validation resolved
- Recursion-verifier constraint gaps patched
What stays the same: No changes to EVM, fees, contracts, or user-facing interfaces.
Technical note: The upgrade requires a new on-chain verifier contract due to tightened prover constraints.

2/ Why this matters OpenVM v1.5.0 + v1.6.0 remediate several critical soundness advisories and raise the provable-security target. Adopting them keeps Scroll's validity proofs aligned with the latest verified-security guarantees of the upstream prover. Tightening the prover's

Scroll Network Upgrade Rolling Out June 25
**Scroll is implementing a network upgrade with the following timeline:** - **Scroll Sepolia**: June 18, 07:00 UTC - **Scroll Mainnet**: June 25, 07:00 UTC **Key Points:** - No action required from users, developers, or dApps - L1 finalization may experience approximately 1 hour delay during rollout - All other network functions will continue operating normally Node operators can reference the official guides for running Scroll L2geth nodes from snapshots on both [Mainnet](https://scrollzkp.notion.site/Running-a-Scroll-L2geth-Node-from-Snapshot-Scroll-Mainnet-a82f7eea296b496e9b34812de11b1a23) and [Sepolia](https://scrollzkp.notion.site/Running-a-Scroll-L2geth-Node-from-Snapshot-Scroll-Sepolia-1d07792d22af800181e7e2105041ef7c).
Scroll Proposes Dissolving Security Council, Shifting to Admin Multisig
Scroll has announced a proposal to **dissolve its Security Council** and transition protocol admin control to a Scroll Admin multisig over the next ten days. **Key Points:** - The Security Council's cost no longer justified its actual usage over recent quarters - Resources will be redirected toward product development and growth initiatives - The team maintains confidence in their mature, audited infrastructure - Plans to work with stakeholders on a new security council structure better suited to current market conditions The engineering team that built Scroll's infrastructure will continue active maintenance under high security standards. Full contract specifics and governance details are available on the [Scroll governance forum](https://forum.scroll.io/t/governance-update-security-council-transition-contributor-roles-operational-adjustments/1470). This represents a significant operational shift as Scroll optimizes its governance structure while maintaining its commitment to user security.
Scroll DAO Plans Pilot Program for Ecosystem Documentation and Contributor Funding
Scroll DAO is developing a pilot program to create comprehensive ecosystem documentation. The initiative will produce: - A consolidated report - One-page summaries - Ecosystem maps All materials will be published on the forum for DAO and Foundation reference. **Funding Structure** Contributors will receive defined budgets based on: - Project scope - Specific deliverables The Scroll Foundation may provide data and insights to support the effort. This documentation project runs parallel to ongoing DAO-Foundation discussions about ecosystem growth strategies and user acquisition initiatives.
Scroll's Delegate Contribution Program Expands Beyond Simple Voting
The **Delegate Contribution Program (DCP)** is evolving to give delegates structured roles beyond traditional voting mechanisms. Key developments: - Delegates will take on **well-defined responsibilities** aligned with Scroll's strategic priorities - Focus areas include ecosystem growth, network security, and data transparency - The program aims to help the DAO make more effective progress in critical areas This shift represents a move toward more **active governance participation**, where delegates contribute specialized expertise rather than simply casting votes on proposals.
