Joe Biden, an "old man", had unsuccessfully sought the Democratic presidential nomination in 1988 (at the age of 46) and in 2008 (at the age of 66). This time will be his last fight. By the time he takes office in January next year, he will be 78 years old and will be the oldest president in U.S. history. His perseverance stems from flaws: stuttering is ridiculed, and long poems are hard to memorize Biden was born in Scranton, Pennsylvania in November 1942 and moved to Mayfield, Delaware, at age 13. Therefore, he has a strong political presence in Pennsylvania and Delaware. Biden's father was a factory furnace cleaner and a used car photo background removing salesman. The old Biden always said that the measure of a person is not how many times he is knocked down, but how quickly he stands up. Biden thanked his parents for cultivating his strong and determined personality. He was bullied by an older neighbor in his childhood. His mother told him: "Beat them until their nose bleeds, and tomorrow you will be able to strut in the street!" Until middle school, Biden had a stuttering problem and was often ridiculed by children. A teacher, who is a Catholic nun, also mocked his language barriers. Biden mentioned in his memoirs that his mother went to the teacher to theorize and threatened to "smash your nun hat off." To overcome the barrier of speech, he memorized long poems and recited them aloud in front of a mirror. Biden's interest in politics began in college, in part because John Kennedy took office in 1961. During the spring break of his junior year at the University of Delaware, Biden went to play in the Bahamas and fell in love with Syracuse University student Neilia Hunter at first sight, so he transferred to Syracuse University Law School. In 1966, the two got married. Before entering politics, he briefly worked as a lawyer. At the age of 30, he was first elected to the Senate from Delaware and served six consecutive terms, setting two records as the fifth-youngest senator in U.S. history and the longest-serving senator from Delaware.

Marco Lee (Ph.D., Kaohsiung University of Science and Technology, graduate thesis researching the application of blockchain. He used to start a business in the information industry, and was fortunate to experience the process from Web1.0 to Web3.0. Love billiards, self-learning and hands-on I actually do it, and I also like to cook for breakfast. Facebook page: Dr. Mark ) "Blockchain" is not a new term, but it is still puzzling and shrouded in mystery. I only started to understand blockchain after studying blockchain. There are three basic elements in the composition of blockchain, namely decentralization, consensus and currency. Some people may think that as long as photo background removing the blocks are connected to form a chain, it is a blockchain, but the blockchain that I and many blockchain enthusiasts recognize must have the above three elements. So let me start with three elements to illustrate where the decentralized blockchain is hiding. Basic building blocks and concepts "Decentralization" refers to the decentralization of the blockchain, and "consensus" refers to the consensus mechanism adopted in the decentralized state of the blockchain. Anyone can participate, mine and trade in the blockchain without the need for A certain node is specifically trusted. "Currency" refers to digital assets that are publicly tradable in the blockchain, and whose transaction records are stored on a decentralized ledger. Satoshi Nakamoto published "Bitcoin: A Peer-to-Peer Digital Currency System" in 2008, describing a digital currency called Bitcoin and related algorithms, which proposed an electronic transaction system that does not rely on intermediary trust. Let Bitcoin allow two parties who have not yet established trust in each other to make financial payments without a centralized trusted third-party institution, while providing a transparent and protected data storage mechanism.
