2015 was a year of global turmoil. Social events included the Paris terrorist attacks, the Nepal earthquake, the Syrian refugee crisis, and the Formosa Fun Coast dust storm that shocked Taiwan. Economic events included the global market downturn, continued low international oil prices, and the depreciation of currencies of various countries. However, in the same year, Ethereum, a blockchain that subverted the traditional global financial industry, was born.
Ethereum was born at 10:26 a.m. EST on July 30, 2015. Grace Caffyn, a CoinDesk reporter, wrote in the article "Ethereum Launches Long-Awaited Decentralized Application Network" at the time: "It is massive in scale and flexible in design, and it aims to encompass almost everything on the decentralized web." However, the article was also mixed with the opinions of skeptics, who criticized Ethereum for being "immature", "too ambitious", and saying that it "still has a lot to prove."
The founding team named the first version of Ethereum "Frontier". At that time, Ethereum technology was indeed not yet mature and was still in the experimental stage. It was only used by developers to develop programs and allow developers to participate in mining. Steven Taul, then Chief Operating Officer of Ethereum, wrote before the launch:
During the Frontier launch, we hope that early adopters and application developers will build communities and begin to form an active ecosystem. They are like the gold prospectors in the American Frontier, facing great opportunities but also many risks.
It turns out that Steven Taul's prediction was correct. Today, Ethereum has grown into a thriving ecosystem with more than 1.6 million weekly active users, thousands of nodes and communities, and a market value of $226 billion. Over the past 8 years, Ethereum has not only spawned a new era of decentralized applications (DApps), but also served as a launch pad for decentralized finance (DeFi), fueled the NFT craze, and laid the foundation for decentralized autonomous organizations (DAOs).
As Ethereum celebrated its 8th anniversary, Binance founder and CEO Changpeng Zhao (CZ) shared an old photo of him and Ethereum founder Vitalik Buterin taken in 2015 on Twitter.

Zhao Changpeng joked in the post that Vitalik Buterin happened to visit Japan and stayed in his apartment in Tokyo. Although Ethereum had not yet been officially launched, Vitalik Buterin had already started to study and talk about Ethereum (ETH). However, Zhao Changpeng said that he did not sway to buy Ethereum, but he was glad that he missed this investment opportunity, otherwise he would not have the motivation to start Binance.
