The financial company Alpari has published a detailed overview tracing the historical development of payment systems—from early barter to modern digital currencies and central bank digital currencies (CBDCs).
Alpari analyst Anna Bodrova described how the first human societies functioned, based on natural economy and direct exchange. As trade expanded and specialized crafts developed, finding mutually beneficial exchange conditions became increasingly complex, leading to the need for universal equivalents.
Over time, societies used scarce or durable items as mediums of exchange, such as salt, furs, cocoa beans, livestock, tea, cowrie shells, and large stone disks.
The advent of metalworking facilitated the use of copper, silver, and gold as means of payment. Metal coins first appeared in the 7th century BCE in the kingdom of Lydia, located in modern-day Turkey, where King Croesus used separate minting of gold and silver coins with official royal symbols to confirm purity and weight.
During the Tang Dynasty in China, between the 7th and 11th centuries CE, paper receipts began to replace heavy stacks of metal coins, paving the way for the emergence of banknotes. Subsequently, national currencies gradually abandoned their link to precious metals in favor of fiat money, whose value is determined by trust in the issuing state rather than intrinsic material value.
In recent decades, money has increasingly transitioned into a digital format. In addition to electronic bank transfers, the emergence of cryptocurrencies introduced decentralized digital assets operating on distributed networks and cryptographic algorithms. Simultaneously, 41 countries have launched pilot projects for issuing CBDCs.
Despite the rise of digital payment methods, cash remains widely demanded, accounting for 46% of global transactions and 53% of payments in Uzbekistan. Physical banknotes and coins continue to serve a vital function as a financial safety net that does not depend on electricity or banking infrastructure.
