Presentation Transcript

  1. What Is Blockchain Blockchain, at its heart, is a distributed digital ledger that houses all types of data. Cryptocurrency transactions, NFT ownership, or DeFi smart contracts can all be recorded on a blockchain. Although this type of data can be stored in any traditional database, blockchain is special in that it is completely decentralised. Imagine an Excel spreadsheet or a bank database, but instead of being kept in one place by a single administrator, a blockchain database is held on numerous identical copies on numerous machines dispersed throughout a network. Nodes are the collective name for these distinct computers.
