[Vitalik Warns BlackRock and Other Institutions' Holdings Could Pose a Threat to Ethereum] Ethereum founder Vitalik Buterin stated at the Devconnect conference in Buenos Aires that if institutions like BlackRock continue to accumulate ETH, Ethereum could face two major existential threats. Currently, nine Wall Street firms hold over $18 billion worth of ETH, and analysts predict institutional holdings could exceed 10% of Ethereum's total supply. Vitalik highlighted two key risks: core developers being driven away, as institutional dominance might alienate builders focused on decentralization; and institutional pressure potentially leading to poor technical decisions, such as a 150-millisecond block time, which, while beneficial for high-frequency trading, could result in geographic centralization. Vitalik suggested that Ethereum should focus on its global, permissionless, and censorship-resistant protocol characteristics, while preserving its core community and decentralized values.
