Bitcoin transactions

Introduction

Welcome to the world of Bitcoin! This guide will walk you through the basics of Bitcoin transactions – how they work, what they involve, and how you, as a beginner, can understand them. Don't worry if it sounds complicated; we'll break it down into simple terms. Understanding Bitcoin transactions is fundamental to understanding how cryptocurrencies function.

What is a Bitcoin Transaction?

Simply put, a Bitcoin transaction is a record of a transfer of value between two Bitcoin addresses. Think of it like writing a check, but instead of a bank, the record is stored on a public, distributed ledger called the blockchain.

Let's say Alice wants to send Bob 1 Bitcoin. This isn't like sending money through a bank. Instead, Alice creates a transaction that says, "I, Alice, authorize the transfer of 1 Bitcoin from my address to Bob's address." This transaction then gets broadcast to the Bitcoin network.

Key Components of a Transaction

Every Bitcoin transaction has several important parts:

• **Inputs:** These are the Bitcoin addresses where the funds are coming *from*. You can have multiple inputs in a single transaction. Imagine Alice has funds spread across two of her addresses; both would be inputs.
• **Outputs:** These are the Bitcoin addresses where the funds are going *to*. Again, you can have multiple outputs. Alice might send 1 Bitcoin to Bob and 0.1 Bitcoin back to herself as "change".
• **Amount:** The quantity of Bitcoin being transferred in each output.
• **Transaction Fee:** A small amount of Bitcoin paid to the miners for processing the transaction. Think of it as a tip to incentivize them to include your transaction in a block.
• **Digital Signature:** Alice uses her private key to create a digital signature, proving she owns the Bitcoin being sent and authorizing the transaction. This is crucial for security.

How Transactions are Processed

1. **Creation:** You initiate a transaction using a Bitcoin wallet. 2. **Broadcasting:** Your wallet broadcasts the transaction to the Bitcoin network. 3. **Verification:** Nodes on the network verify the transaction's validity – ensuring you have enough Bitcoin and that the digital signature is correct. 4. **Mining:** Miners bundle pending transactions into a block. They compete to solve a complex mathematical problem. The first miner to solve it gets to add the block to the blockchain. 5. **Confirmation:** Once a block is added to the blockchain, the transactions within it are considered confirmed. More confirmations mean greater security. Usually, 6 confirmations are considered very secure.

Transaction Fees Explained

Transaction fees can vary based on network congestion. When the network is busy, you’ll need to pay a higher fee to get your transaction processed quickly.

Fee Level	Transaction Speed	Network Congestion
Low	Slower (hours or days)	High
Medium	Moderate (minutes to hours)	Moderate
High	Faster (minutes)	Low

You can use websites like [1] to estimate current transaction fees. Your Bitcoin wallet will usually suggest a fee based on the current network conditions.

Bitcoin Addresses

A Bitcoin address is like your account number. It’s a string of letters and numbers that identifies where you can receive Bitcoin. There are different types of Bitcoin addresses:

• **Legacy (P2PKH):** Older address format, starting with '1'.
• **SegWit (P2SH):** More efficient, starting with '3'.
• **Native SegWit (Bech32):** Most modern and efficient, starting with 'bc1'.

It's generally recommended to use SegWit or Native SegWit addresses when possible, as they offer lower fees.

Transaction IDs (TXIDs)

Every transaction is assigned a unique identifier called a Transaction ID, or TXID. It’s a long string of characters that allows you to track the status of your transaction on the blockchain explorer. You can use a TXID to prove that a transaction occurred.

Comparing Bitcoin Transactions to Traditional Bank Transfers

Feature	Bitcoin Transaction	Bank Transfer
Speed	Typically 10-60 minutes (depending on fees & congestion)	1-5 business days
Fees	Variable, based on network congestion	Often fixed, can be high for international transfers
Reversibility	Generally irreversible	Can be reversed under certain circumstances
Privacy	Pseudonymous (addresses are not directly linked to identity)	Requires providing personal information
Control	You control your funds	Bank controls your funds

Practical Steps: Sending Bitcoin
