The blockchain, which began as the technology behind cryptocurrencies, has quickly gained resonance beyond the financial world. Initially known to support the operation of digital currencies such as Bitcoin and Ethereum, blockchain has proven to be much more than just a financial infrastructure. It has become the foundation of a digital revolution, with the potential to transform sectors such as supply chains, healthcare and even government. In simple terms, a blockchain is a series of securely and chronologically connected blocks of information. Each block contains a set of data, and the concatenation of these blocks creates an immutable chain. The distinctive feature of the blockchain is its decentralised and distributed nature, which eliminates the need for central intermediaries and paves the way for greater transparency and security. The basic principles are:
- Decentralisation: In a blockchain, data is distributed over a network of nodes rather than being centrally controlled. This decentralisation prevents a single actor from manipulating the system.
- Immutability: Once information is recorded in a blockchain and the chain is confirmed, it becomes virtually impossible to change it. This helps ensure the integrity of the register.
- Consensus: To add a new block to the chain, the majority of nodes must agree on the validity of the information. This process, called consensus, ensures that transactions are verified by the community.
The initial impetus for exploring the blockchain was driven by cryptocurrencies, but its reach has expanded to multiple sectors. To effectively navigate this digital world, it is essential to understand how blockchain works and, more importantly, how to access and interpret key information through tools such as the Blockchain Explorer. In the next chapter, we will explore the critical role played by these tools in illuminating the path through blockchain transparency.
