Glossary

Blockchain is a distributed digital ledger that stores information in blocks that are linked together in a chronological chain. Once data is added to a block, it becomes extremely difficult to alter, which creates a high level of trust and transparency without needing a central authority. Each participant in the network has a copy of the ledger, and transactions are verified through consensus mechanisms like Proof of Work or Proof of Stake.

Beyond cryptocurrencies like Bitcoin and Ethereum, blockchain technology is used in areas such as supply chain tracking, digital identity, smart contracts, and secure record-keeping. Its ability to eliminate intermediaries, reduce fraud, and provide real-time, verifiable data makes it a transformative technology across industries.
