    How Transactions Work in Bitcoin

      Bitcoin transactions are the foundation of its decentralized digital currency system. Unlike traditional banking, Bitcoin allows users to send and receive money directly through a peer-to-peer network without intermediaries. This approach supports Decentralisation and Development, enabling global financial access and independence. Below are six key points that explain how Bitcoin transactions work:

    • Initiation of Transaction: A Bitcoin transaction begins when a user sends funds from their wallet to another user’s Bitcoin address. The sender uses their private key to sign the transaction securely.
    • Broadcasting to the Network: Once signed, the transaction is broadcast to the Bitcoin network, where it is picked up by connected nodes that verify the details.
    • Verification by Miners: Miners validate the transaction by solving complex algorithms, a process central to how Bitcoin works technically. This ensures that the transaction is legitimate and the sender has sufficient funds.
