The Bitcoin blockchain is a decentralized ledger that records all Bitcoin transactions. Introduced in 2009 by Satoshi Nakamoto, this technology comprises "blocks" of data chained together, ensuring transparency and security. Each block contains a group of Bitcoin transactions from a given period. These blocks become unalterable once added to the blockchain, adding to the system's security. Every block has a unique code, called a "hash", which links them in a continuous chain along with the hash of the preceding block. Unlike centralized systems, the Bitcoin blockchain operates across many computers worldwide, ensuring its resilience and integrity.
