Xu Mingxing: From 'Happy Beans' to Operating Systems: What Has Blockchain Experienced in the Past 15 Years? Xu Mingxing recalls how Bitcoin in its early days was more like 'Happy Beans' within the community. He once held an event where 'everyone gets 1 BTC.' 'I can't afford to give them away now, but I hope I can in the future.' He mentioned that back then, no one could predict how blockchain would be regulated or applied. The industry has evolved from the 'Bitcoin era, where only the simplest things could be done—like issuing Tokens on-chain,' to 'Ethereum turning blockchain into a system capable of running programs (a blockchain operating system).' Today, Ethereum is gradually becoming the infrastructure for Dapps, financial-grade applications are continuously being built on-chain, and the development of high-performance chains is accelerating.
