"Simply stated, a blockchain is digital record of assets and transactions. The record of assets and transactions is sometimes referred to as a

“ledger.” The ledger is comprised of bundles of information about any asset of value, called “blocks,” which are then immutably connected to a subsequent block that represents a following step in the ledger of transactions. These blocks are then cryptographically linked together to form a chronological “chain” of the blocks to create the entire ledger (Erevelles et al, (2021), The Consumer Centric Blockchain)."

​

 

"This chain can be extended, one block one at a time, to create a trustworthy, secure and transparent record for the stakeholders of a particular community. The ledger is decentralized and distributed among members of the network, sometimes referred to as “nodes.” This decentralization of the blockchain, unlike the centralized cloud, makes it difficult for hackers to steal data stored on it, as the hacker would have to break into numerous nodes in the network to access the data (Erevelles et al, (2021), The Consumer Centric Blockchain)."
