What is a Bitcoin Wallet? An In-Depth Guide



One of the very first hurdles a user new to Bitcoin will encounter is what to do with their coins once purchased. At the heart of engaging with this revolutionary technology is the Bitcoin wallet, a tool that not only stores your digital wealth but also empowers users to manage their bitcoin with autonomy and security when done properly. This guide delves into the intricacies of Bitcoin wallets, ensuring novices and seasoned users alike can navigate this landscape with confidence.

Understanding Bitcoin Wallets

A Bitcoin wallet is akin to a digital keychain, holding the keys to unlock your bitcoin stored on the blockchain. Each wallet contains a set of private keys, a secret code that allows you to spend your bitcoin, paired with public addresses, identifiers that enable you to receive bitcoin. This fundamental tool interfaces with the Bitcoin network, providing a balance of security and accessibility.

Wallets have come a long way since the inception of Bitcoin, becoming more and more convenient and easy to use, especially for less technically savvy users. Nowadays, most wallets implement the Hierarchical Deterministic (HD) standard. Before we get into some of the more technical aspects, it’s important to understand some of the more basic concepts.

Terminology Brief

Before exploring the intricacies of Bitcoin wallets and their operational flow, it’s essential to familiarize yourself with the following basic concepts:

  • Mnemonic Phrase (Seed Phrase): A series of words generated by your wallet that provides access to the bitcoin you hold. It can restore your wallet if lost or damaged.
  • Private Key: A secret alphanumeric code that proves the ownership of bitcoin in a wallet, allowing the user to spend them.
  • Public Address: An alphanumeric string derived from the public key, used to receive bitcoin. It can be shared publicly.
  • Public Key: Generated from the private key, this cryptographic code is used to create a wallet’s public addresses.
  • Seed: A digital representation of the mnemonic phrase, used to generate all the private and public keys in a wallet.
  • Master Private Key: The root key generated from the seed, from which all other keys are derived in a hierarchical deterministic wallet.
  • Master Public Key: Derived from the master private key, it allows for the generation of public keys (and therefore public addresses) without exposing the master private key.
  • Hierarchical Deterministic (HD) Wallet: A wallet that generates a hierarchical tree-like structure of keys from a single seed, allowing for organized and efficient management of multiple accounts and addresses.
  • Chain Code: Part of an extended key, it helps in generating child keys in an HD wallet, contributing to the wallet’s hierarchical structure.
  • Extended Keys: Keys that include additional data such as the chain code and identifiers, allowing for the derivation of child keys and the reconstruction of the wallet’s key structure.
  • BIP32/BIP39/BIP44: Bitcoin Improvement Proposals that standardize the structure for HD wallets, mnemonic phrase generation, and wallet architecture, respectively.

Understanding these concepts provides a solid foundation for grasping the more complex mechanisms of Bitcoin wallets that we will discuss below.

How do Wallets Work?

The functionality of Bitcoin wallets is rooted in cryptographic principles, enabling secure management of bitcoin. Here’s an overview of the process from generating a mnemonic phrase to the creation of a public address, as used in the HD wallet standard:

Mnemonic Phrase Generation

The journey begins with the generation of a mnemonic phrase, typically 12 to 24 words long, derived from a predefined list of 2048 words. This phrase, based on random selection, serves as a human-readable form of your wallet’s seed.

Seed Generation

The mnemonic phrase is processed through a hashing algorithm to produce a 512-bit seed, incorporating optional passphrase protection for added security. This seed is the foundation from which all cryptographic keys are derived.

Master Private Key and Master Chain Code Generation

From the seed, a master private key, and a master chain code are created. The master private key is essential for generating all subsequent private keys, while the master chain code helps in deriving the corresponding public keys.

Master Public Key Generation

The master public key is calculated from the master private key. It allows the derivation of all subsequent public keys—and therefore public addresses—without exposing the master private key.

Extended Keys

Extended keys carry additional data, like the chain code and parent key identifier, allowing for the reconstruction of the wallet’s key structure if needed.

This intricate process showcases the cryptographic foundation of Bitcoin wallets, ensuring secure and efficient management of bitcoin. Hopefully, you can better appreciate the balance between security, convenience, and control that wallets provide in the Bitcoin ecosystem.

Now, let’s dive into the concept of addresses. It’s important to understand some of the subtleties involved so that you reduce the chances of making mistakes.

Understanding Bitcoin Addresses

Addresses play a critical role in facilitating the secure transfer of bitcoin. Here’s what you need to know about Bitcoin addresses:

  • Definition and Function: A Bitcoin address is a string of alphanumeric characters that represents a destination for a Bitcoin payment. Similar to how an email address works for sending messages, a Bitcoin address allows users to send and receive Bitcoin securely on the blockchain.
  • Generation: Bitcoin addresses are derived from public keys using cryptographic algorithms. Specifically, a public key, generated from a private key, undergoes a series of cryptographic transformations including SHA-256 hashing and RIPEMD-160 hashing. The result is then encoded, typically in Base58Check or Bech32 formats, to create the Bitcoin address. This process ensures that each address is unique and securely tied to its corresponding public key.

Types of Addresses

  • P2PKH (Pay-to-PubKey Hash): Starting with ‘1’, these addresses are the original Bitcoin address format. They directly hash the public key, providing a layer of obfuscation.
  • P2SH (Pay-to-Script Hash): Beginning with ‘3’, P2SH addresses allow for transactions that require a specific set of conditions to be met for the bitcoin to be spent, including multisig configurations.
  • Bech32 (SegWit): Starting with ‘bc1’, these addresses support Segregated Witness (SegWit) technology, which helps in scaling Bitcoin by reducing the size of transactions, thus allowing for more transactions to fit in a block.

Some wallets will offer you the option to select which kind of address format you want to use. If it’s your first wallet and you do not intend on doing complex transactions (which will end up costing you more in fees) and want to save on transaction fees, then select the Bech32 (SegWit) format.

Security and Privacy

To enhance security and privacy, it is recommended to use a new address for each transaction. HD wallets facilitate this practice by generating a hierarchical tree of addresses from a single seed, allowing users to maintain privacy and reduce the risk of revealing their total bitcoin balance.

Address Verification

Before sending bitcoin, verifying the accuracy of the recipient’s address is essential to prevent loss of funds. Double-checking the address and using QR codes can mitigate errors in address entry.

Recovery and Backup

Since addresses in an HD wallet are derived from the wallet’s seed phrase, backing up the mnemonic seed phrase ensures that all associated addresses and their funds can be recovered in case of device loss or failure.

Types of Bitcoin Wallets

  • Software Wallets: Applications running on your computer or smartphone, balancing convenience and security. Mobile wallets like BlueWallet and desktop wallets like Electrum are tailored to different user needs, each offering unique features.
  • Hardware Wallets: Devices such as the COLDCARD and Trezor enhance security by storing private keys on a dedicated device, isolating them from external risks. Ideal for securing large amounts of bitcoin.
  • Paper Wallets: Physical documents containing your private key and public address. Secure from digital threats but require careful safeguarding against physical damage or loss.
  • Web Wallets: Accessible via web browsers, these third-party hosted wallets offer convenience at the expense of increased risk, varying greatly in security measures.
  • Lightning Network Wallets: Specialized wallets like Phoenix facilitate transactions on the Lightning Network, enabling faster and cheaper transfers with unique technological requirements.

Custodial vs Non-Custodial Wallets

The wallet types mentioned above can come in two types: custodial and non-custodial. More on this below:

  • Custodial Wallets: These wallets manage all operations on behalf of the user, offering greater convenience by handling the security, backup, and technical complexity. However, this convenience comes at the expense of autonomy, as you are not in direct control of your funds.
    Using a custodial wallet means that each time you wish to withdraw or transfer funds, you are effectively asking permission from the custodian. While custodial wallets can be integrated into software, web, or even hardware forms, they often reside on exchanges, making them convenient for traders but susceptible to hacking if the custodian’s security is compromised. The trade-off here is between ease of use and the potential risks of third-party control over your bitcoin.
  • Non-custodial Wallets: The antithesis of custodial wallets, non-custodial options put you in full control of your bitcoin and the associated private keys. This model aligns with the core philosophy of Bitcoin by supporting censorship-resistant transactions. With this autonomy comes the responsibility of safeguarding your private key.
    Non-custodial wallets demand a proactive approach to security, such as employing hardware wallets for key storage, creating secure backups of recovery phrases, and understanding the wallet’s operational security. These wallets empower users to directly engage in transactions, maintaining privacy and eliminating reliance on third parties. Available in various formats, including software, hardware, and paper, non-custodial wallets offer a range of security levels and user experiences, emphasizing the user’s ultimate control over their bitcoin.

Hot vs Cold Wallets

These terms refer to the wallets’ connectivity to the internet and, by extension, their vulnerability to online threats.

Hot Wallets

  • Definition: Hot wallets are Bitcoin wallets that are connected to the internet. This includes most software wallets, web wallets, and mobile wallets.
  • Convenience: They offer unmatched convenience for daily transactions, allowing users to send and receive bitcoin with ease. This makes them ideal for spending and receiving on the go.
  • Security Risks: The main drawback is their susceptibility to online threats such as hacking and phishing attacks. The Internet connectivity, while convenient, exposes users to potential vulnerabilities.
  • Use Case: Best suited for smaller amounts of bitcoin that you might use regularly for transactions, similar to a physical wallet used for day-to-day spending.

Cold Wallets

  • Definition: Cold wallets refer to Bitcoin wallets that are not connected to the internet. This category includes hardware wallets and paper wallets.
  • Security: By being offline, cold wallets are far less susceptible to hacking and represent a secure way to store large amounts of Bitcoin. They act as a form of “cold storage,” akin to a safe deposit box for your bitcoin.
  • Accessibility: While highly secure, the trade-off is less convenience. Accessing your funds typically involves extra steps compared to hot wallets, which may not be ideal for frequent transactions.
  • Use Case: Ideal for long-term storage of large amounts of Bitcoin, providing peace of mind through enhanced security measures.

Choosing Your First Bitcoin Wallet

Selecting a wallet is a balance of security, ease of use, and specific features needed. Open-source wallets are preferred for their transparency, allowing the community to audit them for security vulnerabilities. To better benefit from what Bitcoin has to offer, a non-custodial wallet is the way to go.

Setting Up Your Bitcoin Wallet

The setup process involves downloading software or purchasing a device, generating a new wallet, and securely storing the recovery phrase—a critical step for accessing your bitcoin if the wallet is lost.

Using Your Bitcoin Wallet

To receive bitcoin, share your public address. This is typically obtained by selecting the “Receive” option in your wallet. To send bitcoin, use your wallet to input the recipient’s address and the amount, by selecting the “Send” option in your wallet. Regularly monitor your transactions and balance for unauthorized activity. You can learn more about setting up and using your first wallet here.

Security Measures

Prioritize securing your wallet with a passphrase, and two-factor or biometric authentication if available, and consider a hardware wallet for substantial holdings. Regular backups and meticulous private key management are essential to mitigate loss or theft risks. Remember, anyone with access to your mnemonic phrase, private key, or seed can steal your funds. Here are some important security do’s and don’ts:

  • Never make a digital copy of the seed, private key, or mnemonic.
  • Write down the mnemonic phrase on paper or a metal backup. Make sure that it is legible and in the correct order.
  • Don’t keep your backup out in the open, keep it somewhere safe.

Advanced Features and Considerations

Multi-signature Wallets

Enhance security by requiring multiple-party authorizations for transactions, adding an extra security layer. This is a more complex setup, so it’s not recommend for most users. If you want additional security without risking getting lost in the setup or losing some key materials for recovering your funds, you can opt for the a passphrase.


A passphrase in the context of Bitcoin wallets is an optional, additional layer of security used alongside the mnemonic seed phrase. It acts as a custom, user-defined extension to the mnemonic phrase, effectively creating a new and unique set of private keys and addresses when applied. This means that even if someone discovers your mnemonic phrase, they would still need the passphrase to access your funds. The passphrase must be remembered precisely, as its loss can make it impossible to recover the wallet’s contents, just as losing the seed phrase would. Also, keep it stored separately from your backup. You can learn more about passphrases here.

The Evolution of Bitcoin Wallets

From simple software programs to the development of hierarchical deterministic (HD) wallets, the journey of Bitcoin wallet technology mirrors the community’s growing focus on security and usability. The advent of hardware wallets introduced a robust solution for offline key storage, while the Lightning Network’s emergence prompted innovations in wallet functionalities to accommodate its operations.

Bitcoin network fees are payments made to miners for including transactions in the blockchain. These fees fluctuate with network demand, leading to higher costs during peak times. Understanding this dynamic is key to minimizing transaction fees.

The UTXO Model and Its Impact on Fees

The foundation of Bitcoin transactions lies in the Unspent Transaction Outputs (UTXO) model. Each transaction generates UTXOs, which are the starting point for future transactions. Efficient UTXO management is crucial as it directly influences the size and complexity of transactions, affecting fees. Large, unconsolidated UTXOs can lead to higher fees, while streamlined UTXO pools can reduce transaction costs.

What’s a UTXO?

An Unspent Transaction Output (UTXO) represents the amount of bitcoin someone has left remaining after executing a Bitcoin transaction. Efficient management of UTXOs is crucial for optimizing transaction fees.

Strategies to Reduce Fees

Transaction Timing

Fees tend to be lower during times of decreased network activity, typically on Sundays. Plan your transactions for these off-peak times to take advantage of lower fees. You don’t necessarily need to wait for these specific moments but can instead set a lower transaction fee that would likely pass at those times based on the current network activity. 

Timing transactions for lower fees requires patience and may not be suitable for urgent transfers. Users must balance the need for timely transactions against potential savings on fees.

UTXO Management

Efficient UTXO management involves consolidating inputs and planning transactions to minimize their size. Use wallets that support UTXO management features, allowing you to select inputs manually or automatically consolidate UTXOs at opportune times. 

Consolidate UTXOs during periods of low network activity. This can be done by sending smaller amounts of bitcoin to yourself when fees are lower, thus reducing the size and complexity of future transactions. This is to avoid spending small UTXOs which would have dispoportionate fees relative to their value. 

Effective UTXO management demands a deeper understanding of how Bitcoin transactions work, which might be daunting for beginners. However, the long-term benefits of reduced fees can outweigh the initial learning curve.

Use Fee Estimation Tools

These tools analyze the current state of the Bitcoin network to recommend an optimal fee for timely transaction confirmation.

You can utilize wallets or online services, like mempool.space, that offer fee estimation to adjust your transaction fees according to network conditions. This can also be achieved by running your own Bitcoin node. 

While these tools offer guidance on fee rates, they are based on current network conditions and predictions can sometimes be inaccurate. Users must exercise judgment and possibly adjust fees manually if transactions are not confirmed on time.

Use SegWit Wallets

Segregated Witness (SegWit) reduces the size of transactions, leading to lower fees. Introduced through BIP91, a SegWit transaction stores information related to your transaction in the witness space in a block, so it’s not considered when calculating the network fee to pay for the transaction to go through.

Saving block space means saving on network fees — Source

Ensure your wallet supports SegWit (addresses starting with bc1) for transactions to benefit from smaller transaction sizes.

Batching Transactions

Combining multiple outputs into a single transaction reduces the fee per payment. For businesses or frequent users, use wallets that support batching to combine multiple transactions into one. With batching, it’s possible to save up to 75% in fees, depending on the number of inputs.

What Makes Bitcoin Scarce?


Redefining Scarcity in the Digital Age

Bitcoin is more than a financial innovation; it’s a revolutionary redefinition of digital scarcity in the modern era. Traditional scarcity is defined by the economic principle where limited resources contrast with seemingly unlimited human wants, influencing the perceived value of an asset. Bitcoin, as the first decentralized digital currency, introduces the concept of digital scarcity, a novel phenomenon made possible and meaningful through its unique blend of technological and economic properties.

Bitcoin: The First Decentralized Digital Currency

Bitcoin stands apart as the first of its kind: a decentralized digital currency that operates independently of any central authority. It transcends the limitations of physical borders and traditional banking systems, representing a new form of asset that is not just digital but also finite in nature. This characteristic of finiteness is crucial to understanding Bitcoin’s value proposition in the broader context of currencies and assets.

The Mining Process: Establishing Digital Scarcity

The heart of Bitcoin’s network lies in mining, a process that is critical to maintaining its ecosystem. Mining involves validators, known as miners, who use powerful computers to secure the network and process transactions. In return, they are rewarded with new bitcoin.

This process is resource-intensive and deliberately designed to mimic the physical mining of resources like gold, underscoring the concept of scarcity in the digital realm. The comparison to gold is apt, as both resources are finite and require significant effort to extract, which in turn reinforces their value.

The Immutable Laws of Bitcoin’s Code

At the core of Bitcoin’s design are two immutable laws that govern its scarcity:

The Supply Cap: Limiting Bitcoin to 21 Million

Bitcoin’s total supply is hard-capped at 21 million coins. This cap is crucial as it contrasts sharply with the endless printing capabilities of fiat currencies, which are prone to inflation and devaluation. This finite supply echoes the scarcity of precious metals and is a fundamental reason for Bitcoin’s comparison to digital gold.

Bitcoin Controlled Supply Chart

The Controlled Emission Rate: The Halving Events

Every four years, the Bitcoin network undergoes a “halving” event, where the reward for mining new blocks is halved. This mechanism mimics the diminishing returns of gold mining and is pivotal in reducing the flow of new bitcoin into the market, thus enhancing its scarcity.

Bitcoin Halving Schedule Fibonacci Spiral

The Economics of Scarcity: Understanding Bitcoin’s Value

Scarcity is a key driver of value in economics. The limited nature of resources in contrast to human desire and need creates a natural valuation of assets. Bitcoin embodies this principle by limiting its supply, thereby making each unit inherently more valuable as the total cap is approached. This economic principle helps demystify why Bitcoin holds value and continues to attract investment.

Historical Context: Scarcity Through the Ages

Throughout history, the value of assets like gold, diamonds, and rare artworks has been significantly influenced by their scarcity. Bitcoin fits into this historical narrative as a digital asset whose value is derived in part from its limited availability, much like these traditional scarce resources.

Halving Events: Countdown to Ultimate Scarcity

The halving events are not merely technical occurrences; they are fundamental to the economic structure of Bitcoin. Each halving, which occurs every 210,000 blocks or roughly every 4 years, reduces the rate at which new bitcoin are created, thus slowly marching the currency towards its ultimate cap of 21 million. These events are akin to a countdown, with each step heightening the scarcity and potentially increasing the value of bitcoin.

Contrast with Fiat and Altcoins: The Scarcity Differential

In stark contrast to fiat currencies, which are subject to inflation and government control, Bitcoin offers a deflationary alternative. Furthermore, most alternative cryptocurrencies (altcoins) lack Bitcoin’s stringent supply controls, making them more susceptible to devaluation and centralization.

Demand and Scarcity: A Symbiotic Relationship

Bitcoin’s scarcity is significantly amplified by its increasing demand. Factors like its growing acceptance as a store of value, its reputation as digital gold, and the burgeoning interest from both retail and institutional investors drive this demand. This relationship between scarcity and demand creates a powerful economic and psychological appeal.

Lost Coins: An Unintended Boost to Scarcity

A unique aspect contributing to Bitcoin’s scarcity is the phenomenon of lost coins. Over the years, a significant number of bitcoin have been lost due to various reasons, such as forgotten private keys, hard drive failures, or users passing away without leaving access to their Bitcoin wallets.

These lost coins effectively reduce the circulating supply of Bitcoin, further accentuating its scarcity. Unlike traditional assets, these lost digital coins are irretrievable, making each remaining bitcoin even more scarce and potentially more valuable. In 2020, Chainalysis estimated that 3.7 million bitcoin have been lost.

The Psychological Impact of Scarcity

The concept of scarcity has a profound psychological effect on human behavior. The desire to own something rare and valuable is deeply ingrained in human psychology. Bitcoin’s finite nature taps into this desire, creating a strong appeal and demand that extends beyond its economic principles.

Consensus: The Guardian of Bitcoin’s Rules

The Bitcoin network operates on a consensus mechanism, which ensures that its foundational rules, such as the 21 million supply cap, are upheld by the majority of its participants. This consensus model adds a layer of democratic governance to Bitcoin, making any change to these fundamental aspects exceedingly challenging.

Mining Difficulty and Network Security: Safeguarding Scarcity

As Bitcoin evolves, the mining process becomes more challenging, requiring more computing power. This increasing difficulty ensures the security of the network and the integrity of Bitcoin’s scarcity. This dynamic adjustment of mining difficulty is crucial in maintaining consistent block times and the overall security of the Bitcoin network.

Bitcoin and Blockchain: The Value of Proof-of-Work

While blockchain technology is groundbreaking, it’s important to note that its value is fully realized in the context of Bitcoin’s proof-of-work system. This system underpins the security and functionality of Bitcoin’s blockchain, setting it apart from other blockchain implementations that lack the same level of decentralization and security.

Scarcity and Network Effects: A Feedback Loop

Bitcoin’s scarcity is closely tied to its network effects. As more people adopt and invest in Bitcoin, its limited supply becomes more pronounced, leading to increased demand and potentially higher prices. This feedback loop between scarcity and network effects is a critical component of Bitcoin’s economic model.

Conclusion: The Multifaceted Nature of Bitcoin’s Scarcity

Bitcoin’s scarcity is not a mere technical feature; it is a fundamental aspect that emerges from a confluence of technological innovation, economic principles, psychological factors, and network effects. This multifaceted nature of scarcity redefines the concept of value in the digital era, positioning Bitcoin as more than a currency – it is a finite digital resource that offers a new perspective on scarcity and value in our increasingly digital world.

How Are Bitcoins Created? A Closer Look at The Process


One of the common questions in bitcoin that often perplex people is about the origins of bitcoins: How are bitcoins created? To fully appreciate the innovative nature of Bitcoin, it’s essential to understand its creation process.

The term “mining” frequently used in this context can lead to confusion, as bitcoin don’t exist in a physical form as one might assume from the mining analogy. Instead, bitcoin are units of the digital currency, each uniquely associated with public keys and recorded on a public ledger called the blockchain.

How Are Bitcoins Created?

Let’s delve deeper into the concept of mining and how it fundamentally differs from traditional mining practices to better understand where the bitcoin we interact with comes from.

Coal mining in an open pit

Bitcoin miners are given a range of potential solutions to validate a new block of Bitcoin transactions. The challenge lies in finding the missing part of the cryptographic equation, known as the hash, that falls within this range. This process is competitive; the first miner to discover the hash is rewarded with new bitcoin.

To visualize this, imagine being given a 9×9 sudoku puzzle with some numbers already in place. Your goal is to complete the puzzle before anyone else. In Bitcoin mining, this puzzle is akin to finding the right hash value in a sea of quadrillions of possibilities, far more complex than the sudoku analogy suggests.

The Purpose of Bitcoin Mining

Why invest significant time and resources in solving these complex puzzles? Like traditional miners who are rewarded with ore or currency, Bitcoin miners receive new bitcoin as rewards. For each block of transactions solved, miners are currently rewarded with 6.25 bitcoins, known as the block reward or subsidy. This amount, however, is set to decrease with future halvings.

Mining is not solely about earning bitcoin; it’s a critical process for verifying new transactions and adding them to the blockchain, thus maintaining the network’s integrity and security.

The Role of the Bitcoin Protocol in Mining

The process of mining and the rewards associated with it are governed by the Bitcoin Protocol. These rules are crucial in defining the operational framework of Bitcoin mining and the overall management of the Bitcoin network. Let’s explore the key elements of the Bitcoin Protocol that directly impact the mining process.

  1. Supply Emission: The protocol dictates how new bitcoin are introduced. The mining reward halves every 210,000 blocks, approximately every four years, in an event known as “halving.”
  2. Supply Cap: There is a finite limit of 21 million bitcoins, making Bitcoin a scarce resource.
  3. Difficulty Adjustment: The protocol ensures that it takes an average of 10 minutes to solve a block. The difficulty of solving these cryptographic puzzles is adjusted every 2,016 blocks, based on the total computing power in the network.

Enhanced Security and Decentralization Through Mining

An often overlooked yet crucial aspect of Bitcoin mining is its role in enhancing the security and decentralization of the network.

Each miner’s effort contributes to a more robust and secure system. By solving cryptographic puzzles and validating transactions, miners help prevent double-spending, a potential issue where the same bitcoin is spent more than once. Ensuring this takes considerable investment into equipment and electricity.

The block reward not only adds new bitcoin to the total supply according to the protocol rules, but also incentivizes the investment into securing the network.


Understanding Bitcoin supply increase through mining is crucial for comprehending its underlying value and functionality. While complex, this process ensures the security, integrity, and decentralized nature of the Bitcoin network. As Bitcoin continues to grow in popularity and use, the role of mining as a foundational element of this digital asset remains a fascinating and essential topic for enthusiasts, investors, and skeptics alike.

The structure of Bitcoin transactions, taken from its Whitepaper.

What is a Bitcoin Transaction and how does it work?

A Bitcoin transaction is a digital exchange of Bitcoin between two parties. Recorded on the blockchain, these transactions are secure, irreversible, and can be sent globally without the need for intermediaries, making Bitcoin a versatile and accessible financial tool. All you need to complete a transaction is the recipient’s address and enough bitcoin to cover your costs. It’s important to note that once a transaction is confirmed, it is irreversible!

What are Bitcoin Addresses?

Bitcoin addresses are unique strings of characters used to receive Bitcoin. They function like bank account numbers, allowing users to send and receive Bitcoin. Each address is publicly visible on the blockchain, but without directly revealing the identity of the owner, offering a balance of transparency and privacy.

What is a UTXO (Unspent Transaction Output)?

UTXO stands for Unspent Transaction Output, which is essentially the amount of leftover Bitcoin that a user has after conducting transactions. These UTXOs are tracked by the blockchain and used as inputs for new transactions, ensuring the integrity and balance of a user’s Bitcoin holdings.

Think of it as having a bunch of pieces of gold of different weights. Whatever pieces you’ve yet to spend would be considered UTXOs. Imagine now that you owe someone half an ounce of gold, but only have one in your possession. Your ounce of gold will be melted down and 2 new UTXOs will be produced: what you paid out and what you receive as change.

What are Bitcoin Transaction Fees?

Bitcoin transaction fees are small payments made to miners who process and validate transactions on the blockchain. These fees vary based on network congestion and transaction size, incentivizing miners to prioritize your transaction and ensuring the timely processing of transfers.

What are Bitcoin Exchanges?

Bitcoin exchanges are like digital marketplaces where you can buy and sell Bitcoin using different currencies. They’re websites or apps that connect buyers and sellers. You can exchange your dollars, euros, or other currencies for Bitcoins and vice versa. These platforms also show the current market price of Bitcoin. It’s important to use a reputable exchange, as security is a big concern in the world of digital currencies.

What can I buy with Bitcoin?

Bitcoin’s acceptance is growing globally, allowing users to buy a variety of goods and services. From online shopping to travel bookings and even real estate, Bitcoin’s versatility as a payment method is continuously expanding, reflecting its increasing integration into mainstream commerce. Take a look at BTC Map to find physical locations which accept bitcoin as payment.

What are consensus rules?

Consensus rules in Bitcoin are the guidelines that nodes follow to agree on the state of the blockchain. These rules ensure that all participants have a consistent view of the transaction history, maintaining the network’s integrity and trustlessness.

What is a Blockchain?

A blockchain in Bitcoin is a digital ledger that records all transactions chronologically and publicly. Each block contains a group of transactions, linked to previous blocks, creating a secure and immutable chain, making it virtually impossible to alter past transactions. Take a look at Bitcoin’s blockchain here.

What is a Block?

A block is a set of data containing a batch of valid transactions that have been verified and agreed upon by the network participants. Each block includes a cryptographic hash of the previous block, creating a linked chain that confirms the integrity of the preceding blocks.

This chain of blocks forms the blockchain, which serves as a public ledger for all transactions in the network. In Bitcoin, blocks are added approximately every ten minutes through a process called mining, which involves solving complex cryptographic puzzles. This structure ensures the security and continuity of the blockchain, making it resistant to tampering and revision.

What is the Process of Verifying a Bitcoin Transaction?

Verifying a Bitcoin transaction involves checking its validity against the blockchain history. Miners play a key role in this, ensuring transactions are legitimate and adding them to the blockchain, while nodes confirm and propagate the updated blockchain information.

Bitcoin Mining and Network Security

Mining secures Bitcoin and facilitates its operation. We’ll delve into mining, confirmations, who can mine, mining pools, Bitcoin’s security features, and the significance of halving.

What is Byzantine Generals Problem?

Conceptualized in 1982 by Leslie Lamport, Robert Shostak, and Marshall Pease (see the paper), it is a dilemma in distributed computing that illustrates the difficulty of reaching consensus in a system where some participants may be unreliable or malicious.

It involves a group of generals, some of whom might be traitors, needing to agree on a unified battle strategy. The challenge lies in creating an algorithm where all loyal generals reach the same decision, despite the presence of deceitful elements.

This problem is pivotal as it mirrors the need for consensus in a decentralized network like Bitcoin, where nodes must agree on the state of the ledger while ensuring security and resilience against dishonest actors. Bitcoin addresses this issue through its proof-of-work mechanism, enabling a reliable and tamper-proof consensus among participants.

What is Bitcoin Mining?

Bitcoin mining is the process of validating transactions and adding them to the blockchain. This process is also known as Proof-of-Work. Miners solve complex mathematical puzzles, requiring substantial computational power, to secure the network and are rewarded with new Bitcoin and transaction fees.

What is a Confirmation?

A confirmation in Bitcoin occurs when a transaction is included in a block and added to the blockchain. Each subsequent block added provides an additional confirmation, increasing the security and irreversibility of the transaction. Learn more about why confirmations are required here.

Who Can Mine Bitcoin?

Anyone with access to the necessary hardware, software and energy can mine Bitcoin. It involves setting up a mining rig, which requires computational power and electricity, and participating in the network’s transaction validation process. Note that it is incredibly difficult to mine Bitcoin, which is why miners tend to join a mining pool.

What is a Mining Pool?

A mining pool is a group of miners who combine their computational resources to increase their chances of successfully mining Bitcoin. They share the rewards proportionally to the contributed processing power, offering a more consistent payout than mining solo.

Can Bitcoin be Hacked or Counterfeited?

Bitcoin’s architecture makes it incredibly resilient against hacking and counterfeiting. The decentralized network, cryptographic security, and consensus mechanisms ensure the integrity and authenticity of each Bitcoin, making fraudulent activities nearly impossible.

What is the Bitcoin Halving?

The Bitcoin Halving is an event that occurs every 210,000 blocks or approximately every four years, where the reward for mining new blocks is halved. It’s a built-in feature to control Bitcoin’s supply, affecting the rate of new Bitcoin creation and, potentially, its market value.

Governance and Evolution of Bitcoin

Bitcoin’s evolution involves rules and updates. We’ll explore how updates occur, the nature of forks, and the innovative Lightning Network.

Why do Bitcoin Transactions Require Confirmations?


The Symphony of Bitcoin’s Security and Trust

As an advocate and educator in the realm of Bitcoin, I stress the critical role of confirmations in ensuring the network’s security and reliability. These are not just mere technicalities; they are the heartbeat of the Bitcoin ecosystem, ensuring its integrity and trust.

Bitcoin transaction confirmation ensures security, prevents double spending, and upholds the integrity of the network.

Bitcoin is an amalgamation of concepts, where the whole is greater than the sum of its parts. To address this question comprehensively, let’s delve into some of these crucial components: transactions, mining, and consensus rules.

Related reading: Why Your Bitcoin Transaction Is Stuck On Pending

The Essence of Bitcoin Transactions

Bitcoin transactions, forming the lifeblood of this decentralized network, are digital agreements for transferring ownership. They consist of inputs and outputs, creating a chain of ownership. Inputs are references to previous transactions, signifying the source of the funds. Outputs designate the new owners of the transferred bitcoin. This chain is integral to the trust and security of each transaction.

Block 170. Inputs to the left and outputs to the right. Satoshi sent Hal Finney 10btc in 2009.

Mining: The Guardian of the Network

Mining, beyond generating new bitcoin, validates and embeds transactions into the blockchain. This Proof-of-Work (PoW) process is pivotal, requiring substantial computational resources and underpinning the network’s security.

Bitcoin Transaction Confirmation: Building Trust

Confirmations are acknowledgments that a transaction has been validated and added to the blockchain in a block. An unconfirmed transaction can be reversed, using Replace-by-Fee (RBF) or Child Pays for Parent (CPFP), although the latter is less efficient. With zero confirmations, a transaction is theoretically reversible, but adding more confirmations makes this more difficult.

bitcoin transaction confirmation

Confirmations mitigate the risk of double spending, as reversing a transaction becomes exponentially more difficult with each added block. This is due to the need for an attacker to re-mine the blocks containing the transaction and all subsequent blocks, a feat that requires immense computational power, governed by the PoW mechanism.

It’s estimated that attempting such an attack would cost nearly $8 billion in hardware and over $2 million per hour in electricity.

Related reading: 3 Reasons Bitcoin Will Stick With Proof of Work

The Magic Number: Six

Six confirmations are generally accepted for substantial security, making a transaction practically irreversible. This standard reflects the enormous computational effort and associated cost needed to compromise such a transaction.

Andreas Antonopoulos, the famous Bitcoin educator, once illustrated the power behind each confirmation in a talk presented to MIT in 2015. This is what he would sell, given a number of confirmations:

  • 0 confirmations – A cup of coffee.
  • 1 confirmation – A TV.
  • 2 confirmations – A fancy TV or a cheap car.
  • 3 confirmations – A nice car.
  • 4 confirmations – A fighter jet.
  • 5 confirmations – An aircraft carrier.
  • 6 confirmations – OPEC’s budget for the year.

This is the cost of attack or reversing the transaction scales exponentially with each confirmation.

Conclusion: The Mathematical Guarantee

Bitcoin offers a mathematical guarantee of transaction irreversibility unparalleled in the traditional financial system. The system of confirmations is a symphony of technological innovation and cryptographic security. It’s a dance of numbers where each confirmation step reinforces the trust and integrity of transactions.

How to Recover Your Bitcoin Wallet: A Comprehensive Guide



Understanding the foundational aspects of Bitcoin is crucial for all users, whether they are new or experienced. This guide is designed to help you recover bitcoin wallet, Bitcoin keys and addresses, giving you a clear path to regain access to your bitcoin in different situations. If you wish to understand better the foundational aspects of your wallet, keep reading, else you can skip to the section that talks about recovering lost bitcoin.

Recover Bitcoin Wallet: Understanding Bitcoin’s Cryptographic Foundations

Bitcoin’s revolutionary approach to decentralized finance hinges on its use of cryptography, specifically public-key cryptography, to ensure the secure ownership and transfer of funds. Here’s how it works:

1. Private Key Creation

Every Bitcoin wallet begins with the creation of a private key. This key is a 256-bit number chosen randomly within the range defined by the Secp256k1 elliptic curve standards. Virtually no number falls outside this range, ensuring every private key is unique and secure.

What is a Cryptographic Key?

Think of a cryptographic key as a special kind of secret code or password that can lock (encrypt) or unlock (decrypt) information. Just like a physical key can lock or unlock a door, a cryptographic key can secure data so that only someone with the right ‘key’ can read it.

What is an Elliptic Curve?

An elliptic curve in cryptography is like a set of mathematical rules that creates a playground for securing information. It’s a curved line that has special properties. When we use these properties in calculations, we can create strong ‘locks’ for our digital information that are very hard to break without the ‘key’.

SECP256K1 Elliptic Curve
Private Key Formats

2. Public Key Derivation

From this private key, a public key is derived through Elliptic Curve Cryptography (ECC). This process is a one-way function—meaning that while anyone can generate a public key from a private key, the reverse is impossible. This is the essence of asymmetric cryptography: it allows you to share your public key without compromising the security of your private key.

public private key one way function
Public-Private Key One Way Function

3. Bitcoin Address Generation

The public key is not typically what you share with others; instead, it’s hashed using SHA256 and RIPEMD160 functions to create a public key hash. This hash is then encoded into a Bitcoin address using Base58, a format that is compact and easy to read. This address is what you provide to others to receive Bitcoin.

What is SHA256?

Imagine SHA256 as a super complex blender for data. You throw in any amount of ingredients (your data), and it blends them into a smoothie (a fixed-size output) that looks nothing like the original ingredients. No matter how many times you blend the same ingredients, you’ll always get the same smoothie, but you can’t ever get the original ingredients back from the smoothie. This unique blend represents your data securely and consistently every time. The U.S. government requires its agencies to protect certain sensitive information using it.

What is a Public Key Hash? 

A public key hash is like a unique nickname for your public key in the world of cryptography. Just like you might use a nickname that’s easier for friends to remember than your full name, a hash is a shorter and more convenient version of your public key. It helps keep your real public key private while still allowing you to receive Bitcoin transactions securely.

What is RIPEMD160? 

RIPEMD160 is a way of shortening information, similar to condensing a long story into a brief summary. It takes input, like a public key, and outputs a shorter, fixed-length sequence of numbers and letters. This summary is unique; even the smallest change in the original story creates a completely different summary, making it a useful tool for verifying the integrity of data.

What is Base58? 

Base58 is like an alphabet for computers to communicate numbers and letters in a way that is easier for humans to read and write. It’s a method of writing data that avoids characters that might look similar, like ‘0’ (zero) and ‘O’ (the letter O), reducing the chance of errors when copying or transcribing. This is especially helpful in the world of Bitcoin, where making a mistake in a long address could mean sending money to the wrong place.

4. Digital Signatures:

When you wish to send bitcoin, you must prove ownership without revealing your private key. This is done through a digital signature produced by the Elliptic Curve Digital Signature Algorithm (ECDSA). This signature is proof that the transaction was authorized by the owner of the private key, without ever exposing it.

Types of Wallets and Key Management

The Bitcoin ecosystem has evolved to offer various wallet types, each with its own approach to key management. They consist of Non-deterministic (Random) Wallets, Deterministic (Seeded) Wallets, and Hierarchical Deterministic Wallets (HD Wallets, BIP-32/BIP-44). The key structures among them vary significantly. Here’s a breakdown of the keys used in each of these wallet types:

Non-deterministic (Random) Wallets

These are the simplest forms, where each private key is generated independently and randomly. There’s no connection between the keys, necessitating individual backups for each.

Non-deterministic (Random) Wallets
A Visualization of Non-deterministic (Random) Wallets
  • Individual Private Keys: Each key is generated randomly and independently. There is no mathematical relationship between these keys.
  • Individual Public Keys: Each public key is derived from its corresponding private key.
  • Individual Bitcoin Addresses: Each address is generated from its corresponding public key.

In Nondeterministic wallets, each key and address is a standalone entity, requiring each private key to be backed up separately.

Deterministic (Seeded) Wallets

As a significant advancement, these wallets use a single seed to generate all subsequent keys. If you have the seed, you can recreate all the keys and addresses associated with your wallet.

Deterministic (Seeded) Wallets
A Visualization of Deterministic (Seeded) Wallets
  • Seed (Root Private Key): A single seed (root private key) is used to generate all other keys. This is usually represented as a mnemonic phrase for ease of use.
  • Derived Private Key: Generated from the seed using a deterministic algorithm.
  • Derived Public Keys: Each is derived from its corresponding private key.
  • Bitcoin Addresses: Each address is created from its respective public key.

In Deterministic Wallets, backing up the seed (root private key or mnemonic phrase) is enough to recover all associated addresses and funds.

Hierarchical Deterministic Wallets (HD Wallets, BIP-32/BIP-44)

These wallets take key generation a step further. From the master seed, a master private key is created, along with a master public key and a master chain code. This master public key can then be used to generate a tree of child keys, each of which can produce further grandchild keys, allowing for a structured and organized system of addresses and keys that can all be restored from the initial seed.

Hierarchical Deterministic Wallets
A Visualization of Hierarchical Deterministic Wallets
  • Root Seed: The starting point for all key generation, which can also be converted into a Mnemonic Phrase, often represented by 12-24 English words.
  • Master Private Key: Generated from the root seed through a one-way hash function.
  • Master Public Key: Derived from the master private key, used to generate public keys/addresses without exposing the private keys.
Hierarchical Deterministic Wallets
A Visualization of Key Generation in Hierarchical Deterministic Wallets (HD Wallets)
  • Hierarchical Private Keys: Generated from the master private key, following a tree structure (hierarchy).
  • Hierarchical Public Keys: Each is derived from its corresponding hierarchical private key.
  • Bitcoin Addresses: Generated from the hierarchical public keys.

HD Wallets, particularly those conforming to BIP-32/BIP-44 standards, offer a structured way to generate multiple keys and addresses from a single seed. This makes backup and recovery more streamlined, as only the root seed (or mnemonic phrase) needs to be secured.


BIP39 has been the go-to method for generating recovery codes for years, translating a sequence of bytes into a series of words. A user’s wallet presents a sequence of words that encode the wallet’s backup, allowing for recovery and re-creation of all derived keys.

The use of a passphrase adds a layer of security, essentially creating an infinite array of potential wallets from a single recovery code. This optional passphrase enables a second security factor and can also serve as a form of plausible deniability.


Each of these wallet types represents an evolution in key management, offering different levels of convenience, security, and backup efficiency. Understanding the cryptographic underpinnings of Bitcoin is essential for anyone involved in the space.

It not only helps secure funds but also empowers users to make informed choices about their wallet types and management strategies. If you want to learn more about the evolution of Bitcoin wallets over the years, give this article a read. Now, let’s delve into the recovery process in case of lost or misplaced backups.

A Guide Through Common and Uncommon Scenarios

Losing access to Bitcoin keys can induce panic, but understanding the nature of your wallet and the available recovery options can turn the tide. Here’s a deeper dive into what you can do in different scenarios using Electrum wallet:

“I lost my wallet! What can I do?”

1. Retrace Your Steps

Sometimes, the issue is not a complete loss but a misplacement. Search through your files, secure storages, and other potential hiding spots. It’s not uncommon to find your backup stored in a safe place and have simply forgotten its location.

2. Import Your Private Key

If you’ve lost access to your wallet application or hardware device but still have your private key stored elsewhere, many wallet applications allow you to import this key directly. This will give you immediate control over your funds.

4. Sweep the Wallet

Sweeping a wallet refers to creating a new transaction to transfer all funds from an old wallet into a new one. This can be done by entering your private keys or mnemonic phrase into a new wallet application, which will then initiate the transfer.

Open your newly created wallet > Wallet > Private keys > Sweep > Enter WIF key

Wallets like Electrum, Bitcoin Core, and Blockstream Green provide a ‘sweep’ feature for your funds. Unlike importing, which retains the same private key, sweeping imports the funds and then transfers them to a new wallet with a different private key. This is done as a best security and privacy practice.

“My bitcoin is on an exchange, how do I get it off?”

If your bitcoin is on an exchange and you want to transfer it to a personal wallet for more control or security, you’ll need to:

  1. Set up a personal wallet, ensuring it’s secure and backed up.
  2. Obtain a receive address from your personal wallet.
  3. Initiate a withdrawal from the exchange to that address.

Make sure to transfer a small amount first to ensure everything works smoothly before transferring the rest.

Edge Cases

I have a Multi-signature Scheme

  • You have all of the private keys used to create the scheme: You’re in full control. Use a wallet that supports multisig to spend or transfer funds.
  • You have enough keys to meet the quorum and the Wallet’s Master Public Key: You can still access your funds. In a multisig wallet, the master public key and quorum keys can be used to reconstruct the necessary signatures to execute transactions.
  • If you lack the minimum amount of keys or meet the quorum but do not have the wallet’s master public key to reconstruct the redemption script, then your bitcoin is likely lost.

I Used a Passphrase

If you’ve used a passphrase with your mnemonic phrase, you’ll need to remember it to access your funds. Without it, even the mnemonic phrase won’t be sufficient, as each passphrase leads to a different set of derived keys (effectively, it’s a new wallet).

I Only Have SeedXOR Backup Left

SeedXOR is a method of splitting your seed into parts. You’ll need all the parts to reconstruct the original seed. Once you have the pieces, combine them using the XOR operation to recover your original seed.

I Am Missing Words from Mnemonic Backup

Tools like FinderOuter or btcrecover can assist in recovering a mnemonic phrase when only a few words are missing. They use the known words and the structure of the mnemonic to guess the missing parts. Using these tools does require some technical skills and a proper setup to avoid compromising your private key. Also, if you attempt brute-forcing, know that it gets exponentially more difficult the more words you need to uncover.

My Bitcoin Was Stolen (Observed Outgoing Transaction)

Unfortunately, if the transaction is confirmed on the blockchain, it’s irreversible. Your focus should shift to security—understanding how the theft occurred and enhancing your wallet’s protection to prevent future occurrences. Report the theft to the relevant authorities, and if the amount is significant, consider getting legal help.

Future-Proof Your Wallet

Bitcoin security

Creating additional backups of your recovery phrase is crucial. Store these in multiple secure locations or on engraved steel plates. Post-recovery, enhance your Bitcoin security:

  • Store recovery phrases in secure, diverse locations.
  • Regularly inspect private key backup locations to ensure their integrity.
  • Use multi-signature wallets or a passphrase for extra security.
  • Keep wallet software up-to-date.
  • Keep a copy of your wallet fingerprint.
  • Note down the derivation path, especially if not using a default path.
  • Engrave or stamp your private key in steel to timeproof your backup.


No matter the scenario, the best defense against losing access to your Bitcoin is a good offense: meticulous backups, a clear understanding of your wallet’s recovery processes, and regular checks to ensure your recovery information is accurate and accessible. With the right preparations, recovering your Bitcoin, even in complex situations like multisig schemes or lost passphrases, is a manageable task.

How is a Bitcoin address generated from a public key?

The public key is hashed using SHA256 and RIPEMD160 functions, then encoded into a Bitcoin address using Base58.

What is the purpose of SHA256 in Bitcoin?

SHA256 is a cryptographic hash function that secures data by blending it into a fixed-size output, making it secure and consistent.

What is a public key hash in Bitcoin?

A public key hash is like a unique nickname for a public key in cryptography, making transactions secure while keeping the actual public key private.

How does Base58 contribute to Bitcoin address encoding?

Base58 is a method of writing data that avoids characters that might look similar, making it easier for humans to read and write Bitcoin addresses.

What is the role of digital signatures in Bitcoin transactions?

Digital signatures, produced by the Elliptic Curve Digital Signature Algorithm (ECDSA), prove ownership of a private key without revealing it during a transaction.

What are the different types of Bitcoin wallets?

There are Non-deterministic (Random) Wallets, Deterministic (Seeded) Wallets, and Hierarchical Deterministic Wallets (HD Wallets, BIP-32/BIP-44).

How does a Deterministic Wallet differ from a Non-deterministic Wallet?

Deterministic Wallets use a single seed to generate all subsequent keys, allowing for easier backup and recovery, while non-deterministic wallets produce private keys randomly.

What is the significance of Hierarchical Deterministic Wallets (HD Wallets)?

HD Wallets offer a structured way to generate multiple keys and addresses from a single seed, streamlining backup and recovery.

14. What is BIP-39, and how is it used for wallet recovery?

BIP-39 translates a sequence of bytes into a series of words, creating a mnemonic phrase for wallet backup and recovery.

How can a passphrase enhance wallet security in Bitcoin?

A passphrase adds an extra layer of security, creating an infinite array of potential wallets from a single recovery code.

What should I do if I lose access to my Bitcoin keys?

Retrace your steps and find either your mnemonic phrase or your private keys. Then import your private key or mnemonic backup, or use the “sweep” feature in wallet applications like Electrum.

How can I transfer Bitcoin from an exchange to a personal wallet?

Set up a secure personal wallet, obtain a receive address, and initiate a withdrawal from the exchange to that address.

What should I do if my Bitcoin is stolen with an observed outgoing transaction?

If the transaction is confirmed on the blockchain, it’s irreversible. Focus on enhancing wallet security, report the theft, and consider legal assistance for significant amounts.

How can I recover a mnemonic phrase with missing words?

Tools like FinderOuter or btcrecover can assist in recovering a mnemonic phrase when only a few words are missing, but technical skills are required.

What are the best practices for securing Bitcoin and preventing loss of access?

Regularly inspect private key backup locations, use multi-signature wallets or a passphrase for extra security, keep wallet software up-to-date, and store recovery phrases in secure, diverse locations.
