What is blockchain?

Blockchain is the technology that underpins virtually all cryptocurrencies.

It functions as a distributed public ledger, where each transaction is grouped into blocks and linked chronologically, forming a chain.

The main advantages of blockchain are:

• Transparency
• Cryptographic security
• Decentralization
• Impossibility of altering old records

This technology is also being used in other areas such as smart contracts, logistics, digital identity, and financial systems.
