What underpins cryptocurrency: blockchain technology

Cryptocurrencies such as Bitcoin and Ether have gained popularity due to their decentralized nature, with blockchain technology at their core. This is a distributed database that ensures transaction security, eliminating the need for intermediaries such as banks. Each block of data in the chain contains transaction information, and once confirmed, it is added to an immutable chain, making the process transparent and tamper-proof. The main idea of blockchain is trust, based on mathematical algorithms and the principle of consensus, which allows network participants to reliably confirm data.
