Blockchain is a decentralized, digital ledger of transactions that is shared across a network. It's also known as Distributed Ledger Technology (DLT).
What is blockchain in simple words?
Definition. A blockchain is “a distributed database that maintains a continuously growing list of ordered records, called blocks.” These blocks “are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.
What are the 4 types of blockchain?
Four common types of blockchain: public, private, hybrid and consortium. A growing number of blockchain categories exist under the umbrella of permissioned or permissionless. The evolving nature of the Web3 ecosystem means there's some ambiguity when it comes to categorizing blockchains.
