According to @TommyDeng_DAO, Vitalik delivered a keynote speech on Ethereum's future ten years at the EDCON2024 conference in Tokyo, saying that Ethereum will focus on building applications. The categories that have been relatively successful so far include DeFi, DID (ENS), DAO, and NFT. He also highlighted the prediction market Polymarket, the social media aggregator Firefly under Mask Network, the wallet Daimo, and the voting tool Rarimo. Vitalik also proposed several ideas, including trying to encrypt the private key directly in the chip of the mobile phone, so that the mobile phone is the wallet; putting part of the private key in a compliant custodian; and using ZK technology to link personal KYC information with the wallet.
