Twelve years after their professional split, Cardano creator Charles Hoskinson has publicly challenged Ethereum co-founder Vitalik Buterin and the Ethereum Foundation, offering to help them formalize their governance structure. The offer came in response to the Ethereum Foundation's publication of its new "Mandate" on March 13, 2026.
The Mandate outlines three core pillars for the Foundation's future work: subsidiarity (decentralizing decision-making), protection of values, and temporality. The latter principle explicitly states that the Ethereum Foundation's role should eventually dissolve, aiming for a fully autonomous ecosystem.
Hoskinson, in a post on X (formerly Twitter) on March 16, 2026, responded with irony and a direct offer. He suggested the document was an attempt by Ethereum to "catch up" with Cardano's established on-chain governance. "'Mandate' or Constitution, if you will. We could introduce them to UBA if they want to have a convention...." Hoskinson wrote, referring to the University of Buenos Aires.
He pointed to Cardano's own constitutional process, which was solidified at a global convention held at the University of Buenos Aires' Faculty of Law in December 2024. Hoskinson framed this event as the effective constitution of the Cardano blockchain.
The core of Hoskinson's critique lies in the enforcement mechanisms. He argues that the Ethereum Foundation's Mandate relies on "moral authority and potential loss of trust from developers," whereas Cardano has instituted a formal Constitutional Committee with explicit veto power over upgrades deemed to violate its foundational laws.
This public exchange reignites the long-standing rivalry and philosophical debate between the two blockchain projects, centering on the maturity and formalization of decentralized governance. The immediate question is whether this remains a symbolic jab or evolves into a substantive dialogue on blockchain constitutionalism.
