Blockchain technology is a distributed database or ledger that is shared among a computer network’s nodes. It is best known for its role in cryptocurrency systems, but it has many other uses, such as making data immutable and reducing the need for trusted third parties. A blockchain consists of programs called scripts that enter and access information, and it is distributed, meaning multiple copies are saved on many machines. The blockchain collects transaction information and enters it into a block, which is then encrypted and added to the chain.
