Blockchain

« Back to Glossary Index

The blockchain is a digital ledger of all the transactions ever made in a particular cryptocurrency. It’s comprised of individual blocks that are chained to each other through a cryptographic signature. Each time a block’s capacity is reached, a new block is added to the chain. The blockchain is repeatedly copied and saved onto thousands of computers all around the world, and it must always match each copy. As there is no master copy stored in one location, it’s considered decentralized.
