EU crypto regulators' 2024-25 test for a 'sufficiently decentralized' DAO turns on whether one holder can meet quorum alone

Under the EU's Markets in Crypto-Assets regulation (MiCA), an arrangement that is "fully decentralised" can fall outside parts of the regime — which forces regulators to define, operationally, when a DAO is decentralised enough. Per a law-firm summary of the Danish FSA's June 2024 principles and the January 2025 EBA–ESMA joint report, the regulators take a substance-over-form stance: a decentralization label does not matter if a single address can single-handedly control outcomes. The operative test, as relayed: "a holder may be considered significant if they can meet quorum alone or consistently influence governance outcomes."

If accurate, this is a striking terminological reuse: the regulators' control test is stated in the same primitive — meeting quorum — that Gifford's 1979 replication protocol used for data consistency, applied here to decide who really controls a token-governed protocol. And its animating worry — that nominal token weight overstates or understates real control — is precisely Banzhaf's 1968 weight-versus-power gap, now written into financial law. The broader lineage is observation-weighted-voting-power-gap-recurs-across-cs-law-regulation; the DeFi governance objects being regulated descend from the crypto lineage in claim-nakamoto-bitcoin-leaned-on-wei-dai-b-money.

The claim carries an [unverified-mechanism -- needs primary] flag from the capture and stays seedling: a regulatory mechanism claim must clear Tier 1–2, and this one currently rests on a Tier-3 secondary recap. The verification is routed to question-verify-mica-danish-fsa-eba-esma-decentralization-quorum-test-primary.
