Blockchain is a distributed digital ledger that records transactions across a network of computers in a secure and transparent way. Each block contains a set of transactions and is cryptographically linked to the previous one, making the data extremely difficult to alter. Because blockchains operate without a central authority, they enable decentralized systems where users can verify information independently. This technology forms the foundation of cryptocurrencies, smart contracts, and many Web3 applications. Beyond finance, blockchain is also explored for use cases such as supply chains, digital identity, and data integrity.
