  The first cryptocurrency, Bitcoin, works by utilizing a decentralized digital ledger called the blockchain. This blockchain records all transactions made with Bitcoin and is maintained by a network of computers called miners. These miners validate and verify transactions by solving complex mathematical problems, ensuring the security and integrity of the network. Additionally, Bitcoin uses cryptographic techniques to secure transactions and prevent double spending, where the same Bitcoin is spent more than once. This is achieved through a consensus algorithm called Proof of Work, which requires miners to compete to solve mathematical puzzles in order to add new blocks to the blockchain. Once a block is added, it cannot be altered, ensuring the immutability of the transaction history.

  The first cryptocurrency, Bitcoin, works by using a decentralized network of computers to maintain a public ledger called the blockchain. This ledger contains a record of all transactions made with Bitcoin and is accessible to anyone. When a transaction is initiated, it is broadcasted to the network and included in a block. Miners then compete to solve a complex mathematical problem, and the first miner to solve it adds the block to the blockchain. This process ensures the security and integrity of the network, as altering a transaction would require a majority of the network's computing power. To prevent double spending, Bitcoin uses a consensus algorithm called Proof of Work, which makes it computationally expensive to alter the blockchain. This ensures that once a transaction is confirmed and added to the blockchain, it is nearly impossible to reverse.

To prevent double spending, Bitcoin uses a consensus algorithm called Proof of Work, which requires miners to invest computational resources to solve mathematical puzzles. This makes it economically infeasible to alter the blockchain, as the cost would outweigh the potential benefits. Overall, the first cryptocurrency works by combining decentralized network maintenance, cryptographic security, and consensus algorithms to ensure the integrity and security of transactions.
