Blockchain

A block is a complex mathematical problem based on a cryptographic technology (called a “hash”) which computers aim to solve. Once the mathematical problem is solved, the block is ‘complete’. The important property of a block is that if you change any information inside of it – like transaction data – becomes invalid, or broken. The only way to fix it is to replace the incorrect data with the correct, original, data.
When a new block is created, it takes data from the previous block, creating a link – hence the term blockchain. ---Cryptominded.
