Blockchain is a record-keeping technology designed to make it impossible to hack the system or forge the data stored on it, thereby making it secure and immutable.
It is a type of technology (DLT), a digital system for recording transactions and related data in multiple places at the same time. Each computer in a blockchain network maintains a copy of the ledger to prevent a single point of failure, and all copies are updated and validated simultaneously.
Blockchain is also considered a type of database but in how it stores and manages information. Instead of storing data in rows, columns, tables and files as traditional databases do, in blocks that are digitally chained together. In addition, a blockchain is a decentralized database managed by computers belonging to a network instead of a central computer like in traditional databases.
