Understanding Blockchain: The Foundation of Cryptocurrencies

Razumevanje Blockchaina: Temelj Kriptovalut

Blockchain technology is the basis for the operation of cryptocurrencies such as Bitcoin and Ethereum. It is an innovative technology that enables safe and transparent storage of data in digital format. We explored how blockchain works and why it is so important to the world of cryptocurrencies.

What is Blockchain?

Blockchain is a type of distributed ledger or log that records transactions across multiple computers so that the record cannot be changed retroactively without changing all subsequent blocks. This ensures a high level of security and transparency.

Blockchain operation

Each transaction on the blockchain is recorded in a “block” along with a set of other transactions. When a block is full, it is cryptographically locked and added to the “chain” of previous blocks – hence the name blockchain. Each block contains a unique “hash” of the previous block, creating a continuous chain.


One of the main characteristics of blockchain is its decentralized nature. Instead of being stored in one place or server, it is distributed across the entire network. This means that there is no single point of failure and is therefore more resistant to hacking and corruption.

Transparency and anonymity

Blockchain enables a high level of transparency, as the data on the chain is accessible to all users of the network. At the same time, it also enables a certain degree of anonymity, since transactions are visible, but the identity of individuals is protected.

Usage in cryptocurrencies

In the world of cryptocurrencies, blockchain allows transactions to be recorded without the need for traditional financial intermediaries such as banks. This ensures faster and cheaper transactions and opens the door to a wide range of financial innovations.

Other uses of Blockchain

In addition to cryptocurrencies, blockchain is also used in many other sectors such as supply chains, healthcare, elections and copyright, where it provides security, efficiency and transparency.

Blockchain technology is the foundation of cryptocurrencies and brings revolutionary changes in the way we store, verify and manage data. Its decentralized, secure and transparent nature offers many opportunities for innovation and improvement in various industries. As the technology evolves, we can expect even more uses of blockchain in our daily lives.
