  Blockchain plays a crucial role in Bitcoin transactions by serving as a decentralized ledger that records all transactions. It ensures transparency, security, and immutability of the transaction history. Each transaction is added to a block, which is then linked to the previous block, forming a chain of blocks. This chain of blocks, or blockchain, is maintained by a network of computers, known as nodes, that validate and verify transactions. This decentralized nature eliminates the need for intermediaries, such as banks, and allows for peer-to-peer transactions without relying on a central authority.

  The blockchain is like a digital public ledger that keeps track of all Bitcoin transactions. It acts as a distributed database, where every transaction is recorded and verified by multiple participants in the network. This ensures that transactions are secure and cannot be tampered with. The blockchain also allows for transparency, as anyone can view the transaction history. It is the backbone of the Bitcoin network and is essential for ensuring the integrity and trustworthiness of transactions.
