Odaily Planet Daily reported on the scene that Ethereum founder Vitalik Buterin gave a keynote speech at the main venue of TOKEN2049.
He said that he was very excited when he first met Bitcoin in 2014 and called it "the next payment network". He also saw Bitcoin-themed restaurants and Argentines using Bitcoin to pay for coffee; but at that time, these payments did not really use decentralized technology, but were achieved with the help of centralized third-party payments.
"What really hinders decentralized payments is high fees and low efficiency. At that time, using Bitcoin to consume in the real world required a fee of $4 and a 5-minute wait. By 2024, Ethereum L2 will be almost zero gas fee. From this, I realized that today's Crypto is no longer an efficiency-oriented technology, but Digital Concrete, a more solid foundation for building an electronic version of the 'Castle in the Sky'. 'Castle in the Sky' can be a solid fortress for people to shelter their families, or a place for friends to have fun. This is also the ideal form of encryption in my eyes, combining seriousness and fun." Vitalik Buterin explained, and sang a clip of the Japanese version of the theme song of Hayao Miyazaki's anime "Castle in the Sky" on the spot.
