What makes Gnosis unique?

Founded in 2015, Gnosis initially focused on prediction markets, transitioning into a DAO in 2020. Gnosis Chain, born from the merger of GnosisDAO and xDAI, is a community-driven EVM-based blockchain. Governed by a DAO, it ensures resilience and neutrality, with over 140,000 global validators providing operational integrity.
