KBC 14: Which decentralized technology was devised by an anonymous programmer known as Satoshi Nakamoto?
Answer: Blockchain
A blockchain is a type that is made up of a growing list of records known as blocks that are securely linked together using cryptography. Each block includes a cryptographic hash of the previous block, a timestamp, and transaction data. The timestamp verifies that the transaction data existed when the block was created. Because each block contains information about the one before it, they form a chain (compare linked list data structure), with each additional block linking to the ones before it.
As a result, blockchain transactions are irreversible in the sense that the data in any given block cannot be changed retroactively without affecting all subsequent blocks.
A peer-to-peer (P2P) computer network typically manages blockchains for use as a public distributed ledger, with nodes collectively adhering to a consensus algorithm protocol to add and validate new transaction blocks.
