Security Council for Base

The Security Council for Base is the multi-party group of independent entities and individuals whose signatures are required to approve Base Chain contract upgrades.

Purpose

Base’s mission is to build a global onchain economy that increases innovation, creativity, and freedom. That mission is only possible on a decentralized platform. Base is therefore (1) built on Ethereum, the most secure and decentralized L1; (2) built in the open; and (3) committed to a clear set of Neutrality Principles.

As part of the ongoing decentralization roadmap, Base launched permissionless fault proofs in October 2024, decentralized control of contract upgrades via a Security Council in April 2025, and has now reached Stage 1 Decentralization.

Reaching Stage 1 means Base offers stronger security guarantees and fewer trust assumptions. Builders gain infrastructure certainty (no surprise rule changes), and there is no single point of failure — anyone can participate in verifying and securing the network.

Structure

Composition and quorum

Stage 1 Decentralization requires that the group approving Base Chain contract upgrades contain:

• at least 8 participants
• a ≥75% quorum
• a quorum-blocking group outside the main rollup operator (Base)

In addition to Coinbase, the Security Council includes 11 independent entities and individuals from geographically diverse regions. To meet the ≥75% quorum, 9 of the 12 entities (the 11 Security Council members plus Coinbase) must approve any Base upgrade. Upgrades cannot take effect until that quorum signs and approves them. This composition meets all requirements.

Member selection criteria

• Representation across diverse geographic regions and international territories
• Strong alignment with Base’s mission and values
• Diverse organizations — each member represents a separate entity
• Proven track record in the Base and Ethereum ecosystem and good standing in upholding professional and ethical standards in the community
• Technical competency and good security practices — completed screening processes including background checks, with demonstrated ability to securely store and use sensitive key material

Member terms

The Security Council for Base operates on a staggered “cohort” model:

• Cohort 1 — current term lasts until October 2026
• Cohort 2 — current term lasts until January 2027

Roles and responsibilities

Review and approve changes

• Members are notified of proposed upgrades and must verify, approve, and sign them.
• Members must verify, approve, and sign role changes (key rotations for lost devices, member rotations, and similar). Any key rotations are designed not to disrupt quorum or security.

Maintain availability and lines of communication

• Be reachable for scheduled signings, coordination calls, and emergencies.
• Coordinate with other members to resolve urgent issues.

Preserve key security

• Generate and store key material securely.
• Use the keys only for activities directly tied to the Security Council role (upgrades and ownership changes).
• Report any suspected loss of access or compromise immediately.
• Complete onchain safety and security training at the start of each term.
• Participate in periodic liveness checks by signing a message to confirm continued control of the key.

Act in good faith

• Avoid conflicts of interest and disclose any potential conflicts.
• Help remove or replace dysfunctional signers without compromising security.

The future

The Security Council for Base is a meaningful step toward a more decentralized, resilient, and secure Base network. Distributing key responsibilities across trusted, independent participants — combined with permissionless fault proofs — reduces reliance on any single entity and strengthens guarantees for users, builders, and the broader ecosystem.

This is the start, not the end. As Base evolves, the Security Council’s role will be progressively minimized, opening the path to even more trustless infrastructure beyond Stage 1 — Stage 2 — and broader community control.

The mission stays the same: build a global onchain economy that empowers innovation, creativity, and freedom on a foundation everyone can rely on.

Base is for everyone.
