On July 30th, at the Ethereum developer community conference EDCON 2024, Vitalik Buterin gave a keynote speech on "The Next 10 Years of Ethereum". In terms of decentralized Twitter, EtherTweet in 2015 and Firefly (Farcaster+Twitter+Lens client) in 2024. Firefly is actually a hybrid architecture and more scalable. Compared with 2019, Ethereum in 2024 has made great progress in terms of fees, transaction inclusion time (Tx inclusion time), and wallet security. It is expected that in the next five years, everyone will use Safe or other smart contract wallets. I talked about decentralized exchanges and prediction markets in 2014, but I didn't predict the popularity of NFTs. Now Polymarket has lower costs than before.
