How does bitcoin work?
Extracto: Bitcoin, a digital currency, operates on a decentralized network known as the blockchain. This technology provides a secure and transparent system for recording transactions, making it resistant to fraud and manipulation.
Transactions
Bitcoin transactions are recorded on a public ledger called the blockchain. When you send or receive Bitcoin, the transaction is visible to the entire network.
Key Players in Bitcoin Ecosystem
Miners
Miners validate transactions by solving complex math problems, earning Bitcoin as a reward.
Bitcoin Wallets
Wallets are digital accounts that store your Bitcoin and private keys, which are necessary to authorize transactions.
Bitcoin Transaction Process
- Initiate the Transaction: Start by sending a transaction from your wallet to another address.
- Broadcast to the Network: The transaction is shared with miners.
- Mining the Block: Miners compete to solve a math puzzle, and the winner adds the transaction to a new block on the blockchain.
- Verification and Confirmation: Other miners verify the new block.
- Completion: The transaction is complete, and the Bitcoins are transferred.
- Decentralization: No central authority controls Bitcoin.
- Security: Advanced cryptography protects transactions.
- Transparency: All transactions are public and verifiable.
- Immutability: Once recorded, transactions cannot be changed.
- Public Addresses: Legacy addresses start with “1”, Bech32 with “bc1”, and SegWit with “3”.
- Private Keys: Encoded in formats like WIF or as HDPrivateKeys in deterministic wallets.
- Other Identifiers: Include Wallet IDs for wallet software and XPUB for viewing public addresses.
