Blockchain technology is a technology that leads to a chain of blocks, containing digital data stored in a public database. A blockchain collects information together in groups, known as blocks, that hold sets of information It is a distributed database existing on multiple computers at the same time, which constantly grows as new sets of recordings or blocks are added to itBlocks have certain storage capacities and, when filled, are closed and linked to the previously filled block, forming a chain of data known as the blockchain. All new information that follows that freshly added block is compiled into a newly formed block that will then also be added to the chain once filled the data is secured. Hence the purpose of BlockChain is to secure data. Additional Information Blockchain technology History:The first prototype of a blockchain was launched in the 1990s by computer scientist Stuart Haber and physicist W. Scott Stornetta. It was popularized by a person using the name Satoshi Nakamoto in 2008 to serve as the public transaction ledger of the cryptocurrency bitcoin,The goal of blockchain is to allow digital information to be recorded and distributed, but not edited. In this way, a blockchain is a foundation for immutable ledgers, or records of transactions that cannot be altered, deleted, or destroyed. This is why blockchains are also known as distributed ledger technology (DLT)
