The Jiaozi NFT is the digital twin of the world’s first government-issued paper currency featuring elements of modern paper money for circulation management and reserve payment. The paper currency was issued on January 12, 1024, in Chengdu, Sichuan, China by the Jiaozi Affairs, the earliest central bank. The bank operated for more than 400 years. It would be almost 200 years later that Marco Polo introduced the concept of paper money to Europe, and 250 years more before Sweden issued modern paper money in 1661. Besides this Jiaozi, the China Finance Museum are also preparing a second NFT, the Gong silver dollar, minted by the Red Army in 1928. In particular, the heavy historical significance of this silver dollar: the communist movement began in Europe and was always involved in the creation of the financial system. From the Paris Commune (1851), the First International (1864), the Second International (1889), the Third International (1919) to the former Soviet Union (1922), all the financial systems established by the communist regimes failed, but the red financial system established by the Communist Party of China, from the I-Il-il (1928), has successfully grown and influenced the global financial system to this day. This silver coin is the prototype of the Chinese people's coin and is worth collecting. China’s creation of paper money drew upon two of their other well-known inventions – papermaking and printing. Today, paper money is a core instrument of the global and national financial systems. Cryptocurrencies and NFT are also innovative developments in the history of 1,000 banknotes. The China Museum of Finance has been promoting the spread of cross-border communication in China and the global financial industry, setting up Jiaozi exhibition halls and Jiaozi monuments in Chengdu, holding Jiaozi forums, and promoting applications for non-material cultural heritage.
