Now that we understand the technology, let’s return to the genesis of cryptocurrencies. The first one, Bitcoin, was introduced in 2009 by a programmer (or group of programmers) using the pseudonym Satoshi Nakamoto. As of April 2018, there were more than 1,500 cryptocurrencies, according to coinmarketcap.com; along with Bitcoin, Ether and Ripple are the most widely used. The time it takes to mine a block is different for each cryptocurrency. Bitcoin takes about 10 minutes, while others do it almost instantly.
In modern times, central banks emerged at the apex of payment systems. With computerized bank ledgers, the coordinating role of central banks increased. Money serves as a store of value, a means of exchange for goods and services, and a unit of account that measures value. Before money, human societies exchanged goods and services directly—a bushel of grain for a pig, say. As societies grew more complex, commodity monies were developed—from seashells to copper, silver, and gold.
Definition and functioning of cryptocurrencies
Founded in 2017, Solana is a blockchain platform designed to support decentralized applications (dApps). Also referred to as an “Ethereum killer,” Solana performs many more transactions per second than Ethereum. The popularity of cryptocurrencies and their potential for ‘disrupting’ and improving traditional financial systems have led to an ever-expanding list of media commentaries, research papers, and policy reports. Despite the thousands of competitors that have sprung up, Bitcoin—the original cryptocurrency—remains the dominant player in terms of usage and economic value.

Tether was one of the first and most popular of the stablecoins—alternative cryptocurrencies that aim to peg their market value to a currency or other external reference point to reduce volatility.

Many in the financial services industry refer to blockchain technology as distributed ledger technology.

Bitcoin is an innovative payment network and a new kind of money. These are some of the reasons why cryptocurrencies are set to replace traditional money. This is not only the case over the last year, but if we look at the comparison from 2011 to 2024, Bitcoin far outperforms all assets in 11 of these 14 years analysed.

In addition to Bitcoin, some of the best known cryptocurrencies today are Ether (Ethereum), XRP (Ripple), ADA (Cardano), USDT (Tether), SOL (Solana) and DOGE (Dogecoin), among many others.
