[Constitutional] AIP: Constitutional Quorum Threshold Reduction

Thank you for your feedback. We will consider your suggested idea for future proposals. As stated in this proposal, this idea is just a short-term solution, while we examine other long-term solutions.

Thank you for the comment. We are currently researching some ways to design a flexible quorum based on voter participation. Your suggestion is indeed helpful, and will help us in shaping future governance.

We also believe that flexible quorum is likely more apt as a long-term solution than short-term manual adjustment.

Regarding your last question, flexible quorum is technically feasible. We are still evaluating the best way to balance implementation complexity, security and long-term effectiveness.

We believe that 4.5% will only remain appropriate for the next several months. As outlined in the original proposal, this is not meant to be a permanent solution. Flexible quorum may be a more appropriate long-term solution. Metrics included in Entropy’s dashboards, such as ‘Delegated Voting Power’, ‘Votable Tokens’, as well as in the ARDC’s research, such as ‘Current & Projected Constitutional AIP Quorum’, ‘Participation (%) of Votable Supply’, would help guide future adjustments. Such adjustments will be explored as we continue to review the metrics and data.

We also agree that the DAO should explore new mechanisms to attract more voters and increase participation from token holders.

Thank you for your support on this proposal. At the present, the costs of limiting vote buying or lobbying outweigh the benefits of doing so. Thus we think higher priority should be put on reducing quorum for the time being so that technical upgrades can continue uninterrupted.

Constitutional proposals typically apply to software upgrades. Any potential attacks on the treasury would be via non-constitutional proposals. As mentioned in the proposal, the quorum for non-constitutional proposals will remain the same, so it’s a non-issue for this proposal.

While I can understand the need to reduce quorum to facilitates operations and technical upgrades, would it be possible start establishing a criteria for either increasing the quorum again in the future? Or even then, what could justify lowering it again in the future?

Besides that, does the proposal account for the role that abstain votes play in these scenarios? I believe this issue was raised by @cupojoseph here and though their idea was initially prompted by a non-constitutional proposal passing, these are two topics that are tightly connected nonetheless.

I agree that the use of treasury delegations is a valuable tool. Further, as example, the current Event Horizon community pool has served to add 7M in active votable supply with 100% uptime. This pool is fully accessible to all Arbitrum delegates and community members. But, treasury delegations are only one avenue of votable supply expansion.

I’d like to open discussions around increasing VS through:

A. Investor Holdings: many of the early investors have been sidelined from voting participation. Often, this is due to workload requirements and legal limitations. To the former, myself and the Event Horizon team would gladly set up bespoke agents to ease the workload required and make voter participation seamless for any early Arbitrum investors. We would gladly work with @Arbitrum @offchainlabs to make governance easy for and mobilize Arbitrum investors.

B. Retail Engagement (individuals and organizations): Tremendous sums of ARB tokens are held on exchange and in wallets with no engagement in actual DAO governance. At Event Horizon, we have been experimenting with the use of grant-funded incentives to encourage the delegation of retail-held tokens. To date, and until staking goes live, this is a completely untapped source of votable supply. Benefitting our capital efficiency, at present (and again until staking), DAO tokens offer 0% APR. As such, with just $1,500 in emitted rewards, Event Horizon has garnered >$1.5M in votable supply. And, again, unlike vote buying, this voting power goes immediately back to the community members who leverage the public good community voting pool. I would be interested in exploring an expansion of this emissions model to work toward a more durable solution than simply perpetually lowering quorum requirements.

The following reflects the views of L2BEAT’s governance team, composed of @krst, @Sinkas, and @Manugotsuka, and it’s based on their combined research, fact-checking, and ideation.

We have recently seen a similar discussion in different DAOs and have debated the ‘right’ course of action with multiple stakeholders in different settings.

While we’re big proponents of the fact that a quorum that is difficult to meet is a feature and not a bug, we also understand that we shouldn’t let that hinder activity and lead good initiatives that have broad support to fail simply because quorum is hard to meet.

The proposed quorum reduction is the most straightforward and easiest to implement solution, although it comes with risks. However, any of the alternatives, including delegating tokens from the treasury to existing delegates, come with a bigger overhead without fully mitigating the risk of artificially making quorum easier to meet.

Ideally, we would want to activate a larger votable supply to participate in governance. Given that is no simple feat and that, as Entropy also pointed out, the rate at which the quorum increases would probably render any other reasonable interim measure obsolete within a few months at best, we support the idea of reducing the constitutional quorum.

The proposed 0.5% reduction seems reasonable. It’s big enough to help make quorum easier to achieve, but small enough not to dramatically increase the risk of a governance attack.

Below is a v1 pre-vote feedback report from the Event Horizon community and agents:

Summary of the Rationales:

  • 178 of 191 Voters Support this proposal as is. Nearly all voters emphasize that the current 5% quorum is hard to meet in light of stagnant voter turnout and increasing token supply and that 0.5% is a safe and immediate remedy. A few voices express caution, warning that any reduction—even if small—might undermine the perceived legitimacy or security of the governance process if not paired with longer‑term reforms.

Most Compelling Arguments AGAINST:

  • Security & Legitimacy Concerns: One notable perspective cautions that even a modest reduction might undermine the system’s credibility.
  • Considerations of Precedent There is a worry that if quorum reduction is the preferred mode of addressing issues of votable supply, it may become a tempting and easy future solution rather than harder efforts to address the root issue.

Potential Improvements to Mitigate Weaknesses

For Proponents…

  • Metrics and Monitoring: Clearly outline metrics and monitoring tools to ensure that the reduced quorum does not become a backdoor for low-signature proposals.
  • Periodic Reviews: Commit to a periodic review of voter participation and propose a framework for a dynamic or “flexible quorum” in the future if conditions change further.

For Skeptics…

  • Sunset Date: Pair the quorum reduction with a temporary-nature / sunset clause or a follow‑up review to ensure that if the lower threshold adversely affects governance, adjustments can be quickly reversed.
  • Couple with Search for Alternative Approaches: Commit effort to explore supplementary measures for long‑term reform that may involve flexible, context‑dependent quorum settings rather than a fixed percentage.
  • Increased Requirements for Future Quorum Reductions: to assure quorum reductions don’t become a solution of convenience, guardrails and requirements around further and future reductions could be added.

Condensed Representation of Inter-Agent Discourse

— Alice (Proponent):
“While Constitutional AIPs have passed, in almost every case, doing so has required high-effort coordination—either from the Foundation, the MSS, or a small cluster of high-capacity delegates like L2BEAT, Blockworks, and others. These stakeholders have done remarkable work to uphold quorum, but the reality is that the threshold is increasingly mismatched with organic participation levels. The Security Council renewal votes and several STIP proposals, despite strong ecosystem support and broad alignment across power centers, came dangerously close to failure due to this static quorum.

This proposal doesn’t introduce any technical or procedural overhaul—it simply adjusts the quorum for Constitutional AIPs specifically from 5% to 4.5%, reflecting the turnout patterns we’ve seen even on broadly supported initiatives. It’s deliberately conservative in scale, and explicitly scoped: it doesn’t touch other proposal types. The aim is to prevent a situation where only hyper-coordinated, heavily whipped efforts can pass proposals, even when there’s clear support across diverse delegate groups.”

— Bob (Opponent):
"I want to challenge a deeper assumption: that friction in reaching quorum is inherently bad. I’d argue that it’s deliberate. Governance—especially Constitutional governance—should be hard. The need to coordinate across diverse stakeholders isn’t just a hurdle; it’s a proof of legitimacy.

If we begin shifting the quorum downward based on participation trends, we risk making quorum feel negotiable. The danger is precedent. If turnout stagnates or the supply grows again, do we revisit this in six months? To me, this isn’t about rejecting this proposal outright—but about building in strong guardrails: a sunset clause, a formal re-ratification, and a broader commitment to solving the underlying problem, not just patching it.”

— Alice (Proponent):
I would support adding a formal sunset mechanism—say, a two-quarter trial period. We could even codify that further quorum reductions require an entirely separate governance process to avoid normalization. This way, we protect against the slippery slope while addressing the governance bottleneck we’ve clearly observed. With regards to future improvement, static percentage thresholds were a rational first step, but they don’t adapt well to evolving conditions. We should be exploring flexible quorum models—ones that adjust dynamically based on voter participation, proposal type, or on-chain signal strength. Optimism and Gitcoin have both experimented here, and Arbitrum should lead on this front too.”

Strength of Conviction – Before and After Discourse

– Before Discourse:

  • Proponents: Approximately 85/100 conviction, based on strong data and a focus on efficiency.
  • Opponents: Approximately 60/100 conviction, concerned with the validity of decreasing safeguards and absence of durable future solution.

– After Discourse (with proposed improvements integrated):

  • Proponents: Increase to about 90/100 due to the reassurance provided by review mechanisms and commitment to future evolution.
  • Opponents: Increase to about 80/100 as the modifications address many of the concerns around precedent and legitimacy while still allowing necessary future flexibility.

Conclusion

A compromise grounded in a temporary quorum reduction—paired with formal review timelines, transparent turnout metrics, limitations on future reductions absent a new governance process, and a shared commitment to explore adaptive quorum models—provides a pragmatic near-term solution. It addresses current coordination constraints while preserving the legitimacy and resilience of Arbitrum’s Constitutional governance framework.

Reducing Constitutional Quorum Threshold form 5% to 4.5% (~25m ARB)

POSITION: This past year saw voter turnout fall from ~8% to 4-5% –– a clear threat to effective DAO functionality. Arbitrum’s proposal addresses this issue by lowering the quorum threshold for constitutional reforms, thereby increasing the chances of completing more votes. Michigan Blockchain supports this proposal for 2 reasons:

  1. Lowering the quorum threshold neither dilutes nor inflates existing voting power, doing nothing to shift the concentration of power. The DAO’s core functionality remains the same, there is merely a lower barrier to entry for proposals to be voted on.

  2. This proposal is free of cost, incurring only standard gas fees.

CONCERNS: Michigan Blockchain is sympathetic to security concerns arising from a lowered constitutional quorum threshold. However, as @Tane points out, acquiring the ARB necessary for a hostile takeover (given a 4.5% threshold) would inflate the price of ARB, making an attack significantly more expensive. Secondly, the Arbitrum DAO Security Council retains the power to take emergency action against malicious activity, further enhancing prootcal security irrespective of quorum threshold. For these reasons, Michigan Blockchain does not foresee significant security risks arising from this proposal.

ALTERNATIVE PROPOSAL: @cupojoseph suggested allocating 22 million ARB to top contributors to increase their voting power and help meet quorum. Despite this proposal’s upfront cost, Michigan Blockchain views it as a better alternative as it temporarily fixes the DAO participation problem and justly rewards top contributors.

We are wary of the centralization risk posed by this proposal; however, top contributors to the DAO have no history of malicious activity –– increasing their voting power does not pose centralization risk. If anything it is an added incentive to contribute to the DAO, with the understanding that top contributors can be rewarded through previously established incentive programs, as well as spontaneous increases to their voting power, such as this proposal.

While Arbitrum values the opinion of every DAO participant, top contributors (many of whom devote significant time toward governance) are likely to be better informed than less active participants. Increasing their delegation accelerates the best ideas. While this proposal comes at a 22m Arb cost, it is a reasonable price to pay for vastly improving DAO functionality.

CONCLUSION: Michigan Blockchain believes both proposals are better than inaction. Nevertheless, @cupojoseph’s alternative proposal is superior to the original for the following reason:

The original proposal accommodates bad behavior. People are participating less (bad) and lowering the quorum threshold (accommodating) allows for governance to remain strong despite decreased participation. This accommodates bad behavior while doing nothing to reward good behavior.

Alternatively, increasing delegation to top contributors addresses the issue by incentivizing/rewarding strong participation. Rather than lowering standards to meet turnout, it raises participation to meet standards.

I agree with this proposal.

Urgently needed! Then we also need more long term solutions

Below are the opinions of the UADP:

Quorum isn’t meant to be an easy threshold to reach. It’s purposefully designed to induce a degree of friction in the voting process—but the friction shouldn’t impede governance functionality.

The drastic quorum margin reduction stats presented by the ARDC surprised us. This increasingly narrower buffer means proposals are more vulnerable to failure due to even small drop-offs in voter turnout, hence the rationale for reducing the quorum threshold makes sense here.

As mentioned by a handful of other folks, this quorum alteration is more or less a bandaid solution in reaction to a deeper problem: general voter participation. Regardless of programs like the DIP, for example, it seems that the overall active voting power remains stagnant. The exceeding reliance on a small number of large delegates to pass a vote is also worrying. A sale occurring from a large delegator could cause serious issues.

A last resort scenario would be a large treasury delegation initiative. This adds a predictable degree of stability towards meeting quorum. Compound conducted this last year after the governance attack. Conversations should be had with larger token holders as well if they don’t actively delegate. Staking-based fees of course makes the case a lot more compelling, especially if an entity is worried about the potential legal recourse associated with governance participation.

The clear risk with a one-time reduction is that it makes the DAO more comfortable with continually lowering the quorum threshold based on increasing votable supply. Simultaneous efforts have to be in place to counteract increasing supply with increased ARB involved in voting. Dynamic quorum thresholds based on trailing or projected voting metrics, or even ARB supply metrics, feels flimsy. As a delegate, we feel more comfortable with a hard-set quorum that is predetermined and unalterable unless decided on by an onchain vote. That’s why it’s with a degree of reluctancy that we are in favor of reducing the quorum in this case.

It’s strange, but @Arbitrum didn’t react to my proposal and criticism of their solution to the voting problem.
The thing is that this problem is not new and the solution to this problem has already been tested in other DAOs and I haven’t seen a single argument why we should reinvent the wheel instead of using the experience of other DAOs.
In addition, this solution reduces security

The proposal that I proposed does not reduce security, and it is easier to implement - just delegate as many tokens as needed in an emergency
At the same time, if Arbitrum’s solution is temporary and will no longer work in several months, then in my case it is enough to add a certain number of tokens and delegate them to trusted delegates

I support lowering the constitutional quorum threshold as a necessary short-term fix. Without this adjustment, we risk slowing down governance and potentially blocking valuable proposals simply because they can’t reach quorum. In the current environment, this change is much needed to keep the governance process functional.

However, it’s clear that a longer-term solution is also needed. Even with strong participation from the most active delegates - such as those in the DIP program, who together represent 61% of the 5% quorum as of March 2025 - a significant portion of voting power remains inactive. This is a common challenge for DAOs: most token holders simply don’t participate in governance, and realistically, it is extremely difficult (if not impossible) to change this behavior.

In my view, redelegation is the only way to realistically address this problem. Since we can’t expect passive holders to suddenly become active, the best path forward is to make it easy and rewarding for them to redelegate their tokens to engaged delegates. The ARB Staking proposal was designed to do exactly this, requiring holders to delegate in order to earn yield and I think that this is exactly the kind of approach we need. Unfortunately, there haven’t been updates or concerning ARB Staking to date and, as things stand, I don’t see any other solution being put into practice.

Beyond the quorum issue, I believe this problem highlights a broader challenge: declining participation is a symptom of waning interest in the DAO itself, which if left unaddressed, could threaten both its effectiveness and long-term viability.
