Bitcoin is a decentralized digital currency based on blockchain technology. To understand this, let's explore a few key concepts

1. Blockchain

- The core technology of Bitcoin, blockchain manages transaction records in blocks linked together. Each block contains information such as the previous block, timestamp, and transaction details.

2. Distributed Ledger

- Blockchain uses a distributed ledger to share transaction records with all participants in the network. This allows secure recording and management of transactions without relying on a central authority.

3. Cryptography

- Advanced cryptographic techniques are employed to ensure the security of transactions. Digital signatures are generated and verified using private and public keys.

4. Decentralization

- Bitcoin operates globally in a decentralized network without reliance on central authorities or governments. This eliminates a single point of failure and potential attacks.

5. Mining

- Mining involves generating and adding blocks to the blockchain. This process results in the issuance of new bitcoins and the verification of transactions.

Based on these concepts, here is a simplified explanation of how Bitcoin works

- ransaction Creation : Users in the Bitcoin network create and sign transactions.

- Transaction Verification : Generated transactions are verified by nodes in the network to ensure their validity.

- Block Creation : Verified transactions go through a competitive process called Proof of Work, where miners solve a cryptographic puzzle to create a new block.

- Block Addition : Once a miner solves the puzzle, the block is propagated throughout the network. Other nodes verify it and add it to their own blockchains.

- Reward : Miners receive a reward in the form of newly issued bitcoins and transaction fees for successfully adding a block to the blockchain.

Through this process, Bitcoin maintains a secure and transparent digital currency system without the need for central authorities, enabling global usage.
