What Chain Is Bitcoin On?

Bitcoin operates on the Bitcoin blockchain, which is a decentralized ledger that records all transactions in a secure, immutable manner. The Bitcoin blockchain was the first blockchain ever created and is the foundation of the entire cryptocurrency industry. This blockchain is maintained by a network of nodes (computers) that validate and propagate transactions. Each transaction is grouped into a block, and these blocks are linked together in a chain, creating a chronological history of all transactions. The Bitcoin blockchain uses a consensus mechanism called Proof of Work (PoW) to ensure the integrity and security of the network. Miners compete to solve complex mathematical problems, and the first one to solve it gets to add a new block to the blockchain and is rewarded with new bitcoins. This mechanism not only secures the network but also regulates the creation of new bitcoins. The Bitcoin blockchain is known for its robustness and security, being highly resistant to tampering and fraud.
