What is Blockchain Technology? When Blockchain Technology appeared/About Blockchain

Blockchain technology was first introduced in 2008 in a whitepaper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" by an individual or group of individuals using the pseudonym Satoshi Nakamoto. The whitepaper detailed the concept of using a decentralized, digital ledger to record and verify transactions using cryptography, and it served as the foundation for the first implementation of blockchain, the Bitcoin network. The identity of Satoshi Nakamoto is still unknown, and the true identity of the person or group behind the pseudonym remains a mystery.
