Bitcoin and beyond: an overview of the most important cryptocurrencies - bitcoin record ethereum cryptocurrenciesCryptocurrencies are gaining more and more ground in the current economic scenario, becoming an increasingly popular form of investment and an increasingly used technology in various sectors. But what exactly are cryptocurrencies and which are the most important? In this article we will give an overview of the most relevant cryptocurrencies, from the famous Bitcoin to the emerging Cardano, Polkadot and Chainlink.

What are cryptocurrencies

Cryptocurrencies are digital currencies that use blockchain technology to ensure the security of transactions and the creation of new monetary units. The blockchain is a distributed digital ledger, which securely and immutably records the transactions of a cryptocurrency. Cryptocurrencies are decentralized, i.e. they are not controlled by a central authority, but by the people who participate in the network. Furthermore, their creation occurs through a process called mining, which requires a large amount of electronic computing and energy resources. These characteristics make cryptocurrencies an innovative and potentially revolutionary technology.


Bitcoin is the most famous and important cryptocurrency, created in 2009 by an anonymous developer under the pseudonym Satoshi Nakamoto. Bitcoin uses the SHA-256 security protocol for creating new units and securing transactions. Thanks to its decentralization and its security, Bitcoin has become an increasingly used financial instrument, both as an investment and as a means of payment. Furthermore, Bitcoin has spawned an entire industry, made up of exchanges and trading platforms such as the popular one Bitcoin Revolution, wallets, miners and other cryptocurrency related services.


Ethereum is the second most important cryptocurrency after Bitcoin, created in 2015 by Vitalik Buterin. Compared to Bitcoin, Ethereum offers a more advanced technology, called a "smart contract", which allows you to create decentralized applications on the blockchain. This has enabled the development of a wide range of decentralized applications and services, such as Decentralized Finance (DeFi) and Non-Fungible Tokens (NFT). Ethereum has become an increasingly used financial instrument, both as an investment and as a means of payment, thanks to its security and its ability to create tailor-made solutions for its users.

Other major cryptocurrencies

Besides Bitcoin and Ethereum, there are other major cryptocurrencies that have had a significant impact on the cryptocurrency market. Litecoin, created in 2011 by Charlie Lee, was one of the first cryptocurrencies to adopt the Segregated Witness (SegWit) protocol to increase transaction speed and reduce fees. Ripple, on the other hand, is a cryptocurrency created to facilitate real-time money transfers, especially for banks. Dogecoin, created as a joke cryptocurrency in 2013, has recently achieved great success thanks to the influences of social media and the attentions of Elon Musk. Other important cryptocurrencies are Bitcoin Cash, Binance Coin, Cardano, Polkadot and many others.

The cryptocurrencies of the future

In recent years, some cryptocurrencies have emerged that could play a significant role in the future of the cryptocurrency market. Among these, Cardano differs from other cryptocurrencies for the scientific approach to the creation of its blockchain and its modular architecture, which allows you to integrate new functions in a simple way. Polkadot, on the other hand, aims to create an interconnected blockchain network, facilitating the transfer of data and enabling new features through interoperability. Finally, Chainlink seeks to solve the oracle problem by allowing blockchains to access trusted external data. In general, these emerging cryptocurrencies offer new features and solutions to existing problems in the cryptocurrency world.
