Blockchains are essentially digital ledgers that record transactions in a transparent and immutable way from "summary" of Blockchain Technology Explained by Alan T. Norman
Blockchains are essentially digital ledgers that record transactions in a transparent and immutable way. To understand this concept, let's break it down. A blockchain is a distributed database that consists of a chain of blocks. Each block contains a list of transactions, and each block is linked to the previous block through a cryptographic hash. This ensures that the data in the blockchain is secure and tamper-proof. The key feature of a blockchain is its transparency. This means that anyone can view the transactions recorded in the blockchain. This transparency is achieved through a network of nodes that validate and store transactions. Once a transaction is added to the blockchain, it cannot be altered or deleted. This immutability is what makes blockchains so secure and trust...
