  • A blockchain is a database or ledger that holds data in a block-based data structure. It's built on distributed ledger technology, which can be used between parties who don't trust each other with sensitive information. It's because adding something to the blockchain necessitates verification from all other users on the network. To provide cryptographic security, blockchain stores information permanently in uniformly sized blocks, with each block storing the hashed information from the previous block.
  • A database is a central ledger where the administrator keeps track of everything. The administrator grants read, write, update, and delete permissions here. Because they are centralized, maintenance is simple, and productivity is high. However, it has a disadvantage in that, if corrupted, it can compromise all data and potentially change the ownership of digital documents.
