How Bitcoin Transactions Work

Bitcoin is a decentralized digital currency that operates on a network of computers. Transactions are verified by network nodes and recorded on a public blockchain. Here's how a Bitcoin transaction typically works:

1. Initiation:

• The sender initiates a transaction by creating a message containing the recipient's address, the amount of Bitcoin to be sent, and a transaction fee.

2. Broadcasting:

• The transaction message is sent to the Bitcoin network through dedicated nodes called "miners."

3. Verification:

• Miners verify the transaction by checking its validity, ensuring that the sender has sufficient funds and that the transaction meets all network requirements.

4. Mining:

• Each verified transaction is added to a block along with other transactions and the miner's solution to a complex mathematical problem.

5. Block Confirmation (1st Confirmation):

• The found block is broadcast to the network and accepted by other nodes if it meets the consensus rules.

6. Propagation:

• The confirmed block is propagated throughout the network, becoming fully validated once received by a majority of nodes.

7. Additional Confirmations:

• In order to increase transaction security, miners work to add subsequent blocks to the blockchain, creating additional confirmations for the transaction.

8. Transaction Completion:

• When the transaction has received enough confirmations (typically 6 to 10), it is considered irreversible and the funds are transferred from the sender's wallet to the recipient's wallet.

Key Features:

• Decentralized: No central authority controls the Bitcoin network.
• Anonymity: Transactions are recorded on the blockchain, but sender and recipient identities are not known.
• Immutability: Transactions confirmed on the blockchain are permanently and irreversibly recorded.
• Security: Multiple verifications and multiple levels of encryption ensure transaction integrity.
• Transaction Fees: Miners receive transaction fees to process and validate transactions.
