Explore a conference talk from ETHTaipei 2025 where open source contributors Ryan and Violet discuss advanced tools for anonymous communal actions in blockchain environments. The 26-minute presentation delves into zero-knowledge proofs (ZK) for vote privacy, trusted execution environments (TEE) for implementing arbitrary threshold voting systems, and various registration flows that maintain anonymity while enabling collective decision-making. Learn how these cryptographic technologies can be applied to create secure, private voting mechanisms within decentralized communities.
