DeFi Governance Is a Question of Concentration, Not Decentralization
A recent European Central Bank working paper looks to analyze decentralization in DeFi protocols from the standpoint of governance. It finds concentration in governance and that this undermines decentralization. This claim, however, rests on a conceptual error: it conflates system decentralization with governance concentration. And governance concentration that does not affect transaction finality or asset ownership is not relevant to whether a system is decentralized. The distinction matters and clarifies both the paper’s findings and their implications.
At Avalanche Policy Coalition, we have consistently defined decentralization from a technical standpoint. A system or network is decentralized when there is no single source of truth, no single point of failure, and no authority with the ability or responsibility to change data, transactions or balances. It is a definition focused on finality. It ensures that users can trust what they see regarding ownership of assets and the completion of transactions.
The working paper errs by reframing decentralization as a governance question rather than a matter of network finality. It compounds this error by trying to answer the question of who to regulate in DeFi by looking at concentration of governance power and participation across major DeFi protocols. What the paper actually demonstrates is not a failure of decentralization, but the presence of concentrated governance layered on top of decentralized infrastructure. Confusing governance concentration with decentralization risks pushing regulation toward infrastructure rather than actors—undermining the very properties that make these systems trustworthy.
Here is a summary of the paper’s empirical findings: Token ownership is heavily skewed, with the top 100 holders controlling more than 80% of supply across the studied protocols, and the top five holders often control a substantial fraction of that total. Governance systems also rely extensively on delegation, whereby token holders assign voting power to intermediaries. As a result, a relatively small number of delegates exercise a disproportionate share of voting power, in some cases controlling the majority of delegated votes. Delegation thus operates as a structural amplifier of concentration.
The paper also notes that concentration of governance power is further compounded by opacity. A substantial share of the most influential participants cannot be linked to identifiable individuals or institutions, making it difficult to determine whether governance power is independent or coordinated, whether incentives are aligned or conflicted, and whether influence is exercised by insiders, intermediaries, or diffuse communities. At the same time, governance processes themselves do little to redistribute power. The paper shows that most proposals concern operational parameters—risk settings, asset listings, and similar adjustments—while very few address governance structure. As a result, the paper concludes, existing distributions of power tend to reproduce themselves over time.
The paper then concludes that decentralization is a property of governance. Under this view, a system is decentralized to the extent that decision-making authority is widely distributed, no small group can dominate outcomes, and the relevant actors are identifiable and accountable. If governance power is concentrated, the paper concludes that decentralization is incomplete or illusory.
This definition is viscerally appealing, particularly from a regulatory perspective. Regulators require identifiable points of control, and the paper emphasizes the difficulty of relying on governance token holders, developers, or exchanges as regulatory “anchor points” precisely because of opacity and fragmentation in governance structures.
Yet this definition departs from the more established understanding of decentralization in distributed systems, where the concept refers not to governance dispersion but to system architecture: whether there is a single point of failure, a single source of truth, or a single authority capable of altering data or transactions. On the more technically precise definition of decentralization, the protocols studied in the paper—built on public blockchains—remain decentralized.
Framed in these terms, the paper’s findings are best understood as documenting concentrations of governance power, not undercutting decentralization. The paper does not show that any individual token holder, delegate, or developer can rewrite transaction history, override consensus, or unilaterally alter the state of the ledger. Nor does it show that the voting groups have this power. It also implicitly recognizes that where governance does not affect asset ownership or transaction finality, regulatory hooks are difficult to establish. Indeed, as noted above, the proposals on which votes are sought have nothing to do with transaction finality or asset ownership.
At best, the paper can conclude that the infrastructure remains decentralized even if governance becomes concentrated. This distinction suggests a more precise analytical framework. At the infrastructure layer, finality is distributed, consensus is collective, and no single point of failure exists. At the governance layer, ownership can become concentrated, voting power aggregated, and influence unevenly distributed. These are not contradictory observations but complementary ones. DeFi systems can be both decentralized and concentrated, depending on the layer of analysis.
Recognizing this layered structure clarifies the nature of the challenges identified in the paper. The difficulty regulators face is not that decentralization has failed, but that concentration exists without clear attribution. This produces a structural asymmetry. Governance actors can shape protocol outcomes—adjusting parameters, allocating resources, and influencing development trajectories—but they do so within systems whose core integrity cannot be compromised by that concentration. The result is a hybrid condition in which decentralized infrastructure coexists with concentrated influence over things that do not undercut decentralization.
Reframing the issue in terms of concentration rather than decentralization also shifts the focus of regulation. For regulators, the challenge is not identifying a centralized intermediary in the traditional sense (i.e., one that controls transactions or custodies assets), but understanding how concentrated influence operates within systems that lack formal control points on the areas of typical regulation. Addressing these issues will require regulatory approaches that focus on identifiable actors and activities, rather than attempting to impose control at the infrastructure layer where it does not exist.
The ECB paper makes a significant contribution by documenting the realities of DeFi governance. But its conceptual framing requires greater precision. Decentralization and concentration are not opposing descriptions of the same phenomenon; they operate at different levels of analysis. The systems studied in the paper are not failed attempts at decentralization. They are decentralized systems with concentrated governance structures. And where those structures do not affect transaction finality or asset ownership, the system remains decentralized. Recognizing this distinction provides a clearer understanding of both the risks and the possibilities inherent in DeFi.
