Just after New Year's Day in 2009, at 2: 00 am on June 4th, Beijing time, 15, Satoshi Nakamoto dug up the first bitcoin, Chuangshi Block, and won 50 bitcoin prizes. He wrote the following sentence on the blackboard: "Times 2009 1 March 3rd Cell was on the verge of the second bank rescue." On June 3, 2009, the British Chancellor of the Exchequer was about to rescue the bank for the second time. This was the headline on the front page of The Times that day. At that time, under the pressure of the financial crisis, British Chancellor of the Exchequer Darling had to consider taking the second step to alleviate the banking crisis. The impact of the financial crisis continues, and the economies of the United States, the European Union, Russia and other countries have not turned around in the new year.

At 6: 00 pm that day, 15, the building blocks were recorded in the public account book. Blockchain 1.0 era —— The era of encrypted digital currency represented by Bitcoin officially kicked off. However, at this time, Bitcoin is still unknown in the small circle, that is, it is not called "digital gold", and people have not entered the crazy hype. Seven days later, 65438+1October1day, Satoshi Nakamoto developed a client with a very simple name-version 0. 1, which is the first client in the history of bitcoin, which means that any computer can join the bitcoin network to mine and use bitcoin. Satoshi Nakamoto told Halfenny the news.

Hal Finney immediately downloaded the Bitcoin client on his IBM computer, which made him the first Bitcoin miner outside Satoshi Nakamoto. Hal Finney is also known as Watson of Satoshi Nakamoto. When the telephone was invented, Bell called his assistant Watson for the first time: "Watson, come here quickly, I want to see you." Of course, Halfenny is not Satoshi Nakamoto's assistant. On the contrary, according to his qualifications, he is Satoshi Nakamoto's predecessor and a great cryptographer. The day after Hal Finney downloaded it, Satoshi Nakamoto tentatively transferred 10 bitcoins to him, which was the first transfer in the history of bitcoins. In the next few days, Hal Finney and Satoshi Nakamoto communicated many times by email, mainly reporting some faults of 0. 1 client, and then Satoshi Nakamoto fixed these faults.
