The following are the wonderful speeches of some experts: 🪂 AI gradually expands the boundaries of decentralization, The next generation of digital identity has a long way to go Vitalik pointed out that the combination of AI and blockchain is not new. From market-making arbitrage algorithms ten years ago to today’s Agent experiments, AI has long been silently playing a role in the encryption world. Whether it is prediction markets, DAO governance or automated transactions, AI can broaden the boundaries of decentralized mechanisms.； At the same time, he also believes that the network is being controlled by AI and centralized databases. This structure not only verifies identity, but also makes personal privacy almost "naked". The next generation digital identity system must solve the contradiction between identity verification and privacy protection at the same time.  🪂 ZK ID becomes a critical infrastructure and seeks privacy balance Xiao Feng, chairman of Wanxiang Blockchain, said that the essence of the prediction market is to use mathematical algorithms to make transactions closer to the truth. This is closer to reality than polls and is a mechanism that makes the future tradable. AI Agent will bring about a revolution in efficiency, but it will also become a new attack target. Therefore, security and compliance must go hand in hand with innovation. ZK ID (zero-knowledge identity) will become a key infrastructure that protects privacy while generating trusted customer portraits, allowing the financial system to find a balance between "understanding customers" and "protecting privacy."  🪂 Developers can make good use of Ethereum’s future development potential opportunities Audrey Tang, founder of the Ethereum Application Alliance (in preparation)/Shanhaiwu, expressed the view that the Ethereum ecosystem has gradually improved in terms of infrastructure construction, but still faces challenges in application implementation and sustainable community development. He is committed to promoting the creation of a sustainable and long-term influential Ethereum application ecosystem and accelerating the transformation of blockchain from infrastructure construction to application prosperity.  To this end, Du Yu, executive director of Wanxiang Blockchain/general manager of Wanxiang Blockchain Lab, and Li Guoquan, chairman of the Global Fintech Academy/fintech and blockchain professor at the Singapore University of Social Sciences, also said that Ethereum is not only in a leading position at the technical level, but also has significant advantages in regulatory compliance and has become the infrastructure of choice for many financial institutions and governments around the world. Finally, experts recommended that domestic developers actively use the Ethereum test network to conduct experiments, promote cooperation between universities and scientific research institutions, and are optimistic about the potential of Ethereum in emerging fields such as green finance and carbon trading, indicating that it will have a profound impact on the global economy.  🌔 After Party carnival night After the hearty ETHShanghai 2025 event came to an end, the organizer also specially organized an After Party carnival night.
