Top 100 Holders Control Over 80% of DeFi Governance Tokens
A European Central Bank working paper published on March 26 delivered a critical assessment of decentralization in DeFi, finding that ownership is heavily concentrated. The analysis of Aave, MakerDAO, Ampleforth, and Uniswap revealed that across each protocol, the top 100 holders command more than 80% of the governance token supply. This conclusion, based on data snapshots from November 2022 and May 2023, directly questions the decentralized nature of these platforms. The report also identified centralized entities as major holders, with Binance being the largest named centralized exchange wallet across the four protocols.
Delegated Voting Power Exceeds 50% Among Small Groups
The concentration extends beyond token ownership into active governance participation. The paper's authors found that a small number of delegates wield disproportionate influence over key proposals. In Ampleforth, the top 20 voters control 96% of delegated voting power. The situation is similar in MakerDAO, where the top 10 voters hold 66% of delegated votes, and in Uniswap, where the top 18 control 52%. This structure means that critical decisions, particularly those concerning the protocols' risk parameters, are decided by a select few. The report notes that while around one-third of these top voters are unidentifiable, the known participants are primarily individuals, Web3 companies, and venture capital firms, not a broad user base.
Concentration Puts DeFi's MiCA Exemption at Risk
The paper's findings create a significant regulatory problem for DeFi protocols operating in the European Union. The EU's Markets in Crypto-Assets Regulation (MiCA) includes an exemption for services that are “fully decentralised.” The ECB's evidence of concentrated power makes it difficult for these protocols to claim that status. Losing this exemption would subject them to the full weight of MiCA's regulatory requirements, introducing substantial compliance costs and operational hurdles. This difficulty in identifying the true controllers of these protocols complicates regulatory efforts and echoes prior warnings from the Financial Stability Board about DeFi masking traditional financial risks.
