Is Bitcoin or Blockchain the Breakthrough?
In a world ruled by centralized power, where institutions hold immense sway over our lives, a revolution has been simmering for decades.
This revolution is blockchain technology, a decentralized system that promises to shift control from the hands of the mighty few and into the collective. From the seeds of this technological marvel sprouts another innovation, Bitcoin, a digital currency that aims to break free from the shackles of traditional banking and usher in an era of financial freedom.
Which of these technologies is the bigger breakthrough for humanity?
While Bitcoin promises to capture attention for decades to come, most argue blockchain itself is the breakthrough thanks to these three characteristics:
Blockchain's tamper-proof nature and public ledger make it highly secure and transparent. This can be valuable in various sectors like finance (fraud reduction) and supply chain management (tracking product origin).
By eliminating the need for a central authority, blockchain empowers individuals and fosters trust in peer-to-peer interactions. This can be beneficial for voting systems, identity management, and reducing reliance on intermediaries.
Smart contracts, self-executing agreements stored on the blockchain, can automate processes and streamline transactions. This can save time and resources in areas like financial agreements and record-keeping.
I’ll conclude with my personal take on whether Bitcoin or blockchain are the true breakthrough.
You’ll enjoy that train of thought.
Let's start with a dive into the intricate workings of the blockchain and how Bitcoin, built upon its foundations, offers a means for value to flow unhindered within an economy, unburdened by the grasp of corporations and other institutions.
The Birth of Blockchain: A Trustless System
Imagine the internet, but instead of just sharing information, it allows us to share value securely.
This is the essence of blockchain.
It can be ownership of paintings, shares in a company, writing credits on a script… any form of structured information that conveys value.
At its core, a blockchain is a digital ledger of transactions, an ever-growing list of records called blocks. These blocks are linked and secured using cryptography, making it extraordinarily difficult to tamper with the data once it has been recorded.
But it's the way in which this ledger is maintained that sets the blockchain apart. Instead of residing with a single entity, like a bank, the blockchain is distributed across a vast network of computers around the globe. There is no central server, no single point of control or vulnerability.
Herein lies the genius of blockchain: the power to create trust on an unprecedented scale. Because everyone participating in the blockchain network has a copy of the ledger, they can collectively verify transactions. No longer do we need to blindly trust a bank or corporation to handle our money or data fairly. With blockchain, every transaction is subject to the scrutiny of the whole system.
Decentralization: Diluting Power
In traditional systems, power is synonymous with control.
Banks dictate the terms of our financial transactions. Corporations collect and often exploit our personal information. They act as gatekeepers, selectively allowing or denying us access to their services, sometimes based on factors outside our control. These central authorities have the power to charge exorbitant fees, impose arbitrary restrictions, or even deny access altogether.
Blockchain disrupts this power structure. Through decentralization, it removes the middleman from the equation. People can interact and exchange value directly on the network, cutting out the intermediaries. Imagine being able to send money to a family member in another country without the exorbitant fees and delays imposed by traditional banking systems. Blockchain makes such peer-to-peer transactions a possibility.
Transparency: Shining a Light into the Shadows
Transparency is another pillar of the blockchain revolution.
While the identities of users can be shielded with pseudonyms, the transactions themselves are often visible to everyone on the network. This means that we can track the flow of money or the movement of assets with an unprecedented level of accuracy.
In a world where shady financial deals happen behind closed doors, and corporations collect our data in secret, this transparency is vital. It has the potential to reduce corruption and fraud and enable more equitable economic systems where everyone can see how value is distributed.
How Blockchain Works
700+ page books have been written that explain how blocks are formed.
… let’s do the 70-word version instead.
The term "block" in blockchain refers to how data is bundled and stored chronologically. Imagine a series of filing cabinets, each holding a set of papers (transactions) for a specific period. These cabinets are the "blocks."
Here's why it's called a block:
Data Grouping: Each block holds a group of verified transactions, similar to how a filing cabinet holds documents.
Chronological Order: Blocks are linked together in a chronological sequence, just like filing cabinets are arranged in a specific order.
Foundation of the Chain: These interconnected blocks form the foundation of the blockchain, just like building blocks create a chain.
So, the name "block" reflects the way data is bundled and chained together to create a secure and tamper-proof record-keeping system.
(I think of it as a pyramid, but we’ll get to that in second!)
Creating a Block:
Data Compilation: Transactions or information are grouped together into a new block.
Hashing: A unique mathematical fingerprint (hash) is created for the new block, considering the data it holds and the preceding block's hash. This creates a chain-like connection where tampering with one block would alter all subsequent hashes.
Mining (Proof of Work): In some blockchains like Bitcoin, miners compete to solve complex cryptographic puzzles. The winner gets to add the new block to the public ledger and earn a reward (e.g., cryptocurrency). This process verifies the block's legitimacy and secures the network.
Reading a Block:
Public Ledger: All the blocks are chained together chronologically, forming a public ledger that anyone can access (depending on the blockchain's privacy settings).
Cryptographic Verification: Anyone can verify the integrity of a block by checking its hash and comparing it to the previous block's hash. This transparency builds trust in the system.
Extracting Information: By reading the block data, you can see the information it contains, like transaction details or timestamps.
What is a Merkle Tree?
A Merkle tree is a clever data structure used in computer science that plays a crucial role in blockchain technology.
Imagine it like a pyramid.
At the bottom, you have individual transactions. Each transaction is hashed (turned into a unique fingerprint). Pairs of these hashes are then hashed together, creating a new layer. This process continues upwards, with each layer being a hash of the layer below it. Finally, you reach the pinnacle – a single hash called the Merkle Root.
The beauty of the Merkle tree lies in its efficiency. To verify a transaction, you don't need the entire transaction history of the blockchain. You just need the Merkle root, the relevant transaction hash, and the hashes along the path to prove the transaction is included in the block.
The History of Blockchain
Again this is a subject with hundreds of books and tens of thousands of pages at this point, but the history is fascinating and worth exploring quickly — here's a breakdown of the history of blockchain, including key milestones and figures:
Precursors and Early Concepts:
1982: Cryptographer David Chaum outlines a blockchain-like protocol in his dissertation.
1991: Stuart Haber and W. Scott Stornetta publish research on a cryptographically secured chain of blocks to prevent tampering with document timestamps.
1992: Haber, Stornetta, and Dave Bayer improve the system's efficiency by incorporating Merkle trees, allowing multiple documents to be grouped into one block.
1998: Computer scientist Nick Szabo proposes "bit gold," a decentralized digital currency with concepts similar to blockchain.
The Birth of Blockchain and Bitcoin:
2008: Satoshi Nakamoto (a pseudonym, true identity unknown) publishes the Bitcoin whitepaper, titled "Bitcoin: A Peer-to-Peer Electronic Cash System." This paper introduces the first fully realized blockchain design.
2009: Nakamoto mines the first Bitcoin block (the "genesis block") and launches the Bitcoin network, making blockchain a functional reality.
Blockchain Evolution and Expansion:
2014: Blockchain begins to be recognized for applications beyond cryptocurrency. The concept of "Blockchain 2.0" emerges, focusing on uses such as smart contracts and decentralized applications.
2015: Ethereum is launched, a blockchain platform facilitating programmable smart contracts, greatly expanding blockchain's potential.
2016-Present: Experimentation and development boom across various sectors:
Finance: Streamlining financial transactions, trade finance, etc.
Supply Chain: Tracking provenance, improving transparency.
Healthcare: Secure medical record management.
Governance: Voting systems, digital identity solutions.
Arguably the “killer app” on the blockchain is Bitcoin.
Bitcoin: The Vanguard of Digital Currency
Built upon this foundation of trust and decentralization arises Bitcoin, the first and most widely known application of blockchain technology. Bitcoin is a digital currency that acts independently of banks, governments, or any other entity. Unlike physical currencies, like the US dollar, Bitcoin exists purely in the digital realm.
Think of Bitcoin as a form of digital cash. You can use it to pay for goods and services, store value, or simply trade it. Because it operates on the blockchain, Bitcoin inherits those benefits: security, transparency, and a freedom from central control.
Countering the Hold of Banks
The concept of a decentralized world, where power is distributed amongst individuals rather than concentrated in the hands of a few, has long been a utopian ideal.
Bitcoin, a digital currency built upon the revolutionary blockchain technology, takes a significant step towards this vision. Let's delve into the specific ways Bitcoin acts as a catalyst for decentralization, disrupting traditional financial structures and empowering individuals.
1. Breaking Free from Central Banks:
Traditional currencies are issued and controlled by central banks. These institutions dictate monetary policy, influencing interest rates, inflation, and the overall money supply. This control can lead to situations where citizens feel their wealth is at the mercy of decisions made by opaque institutions.
Bitcoin, on the other hand, is completely independent of central banks. Its supply is predetermined, with a finite number of bitcoins ever to be created. This fixed supply removes the risk of arbitrary inflation, a common concern with centralized currencies. Additionally, the issuance of new bitcoins is governed by a predictable algorithm, not by the whims of any authority.
2. Power to the People: Peer-to-Peer Transactions
One of the core principles of decentralization is empowering individuals to interact directly with each other. In the financial world, this translates to bypassing intermediaries like banks when making transactions. With Bitcoin, individuals can send and receive payments directly using their digital wallets, eliminating the need for banks to process the transaction. This not only reduces transaction fees but also cuts out the middleman, giving users greater control over their money.
3. Transparency for All: Immutability of the Blockchain
Decentralization thrives on transparency. Bitcoin leverages the power of the blockchain to achieve this. Every Bitcoin transaction is recorded on a public ledger, accessible to anyone on the network. This ledger is constantly growing, with each new transaction adding a block to the chain. The beauty lies in the immutability of the data: once a transaction is recorded, it cannot be altered or deleted. This transparency fosters trust in the system as everyone can verify the legitimacy of transactions.
4. Censorship-Resistant Transactions: No Gatekeepers Allowed
Traditional financial systems can restrict or block transactions based on their own internal policies or government regulations. Bitcoin, existing outside the control of any central authority, offers a degree of censorship resistance. As long as users have access to the internet, they can send and receive Bitcoin transactions without fear of being blocked by a central institution. This empowers individuals, particularly those in regions with strict financial controls, to participate in the global financial system on their own terms.
5. A Global Currency: Transcending Borders
Traditional currencies are often tied to specific countries, creating complexities in cross-border transactions. Bitcoin, operating on a global network, transcends geographical boundaries. Sending or receiving Bitcoin from anywhere in the world is possible, potentially simplifying international transactions and reducing reliance on foreign exchange markets.
There are challenges to address, such as scalability and energy consumption. However, its core principles offer a glimpse into a future where individuals have more control over their financial lives and participate in a more transparent and inclusive economic system.
Bitcoin is the perfect currency for all of these reasons, and more.

The Future of Bitcoin
The future of Bitcoin is a subject of intense speculation and debate.
While it's impossible to predict with certainty, here are key areas where Bitcoin is evolving and potential directions it could take:
Improved Transaction Speed: One of Bitcoin's core challenges is its limited scalability compared to traditional payment systems. To address this, innovations like the Lightning Network are being developed. The Lightning Network functions as a second layer on top of the Bitcoin blockchain, enabling fast and cheap microtransactions. If successful, this could significantly expand Bitcoin's potential for daily use.
Mainstream Acceptance: As Bitcoin gains popularity, the regulatory landscape will continue to evolve. Clearer regulations could increase institutional adoption of Bitcoin, paving the way for greater integration with established financial systems. This mainstream acceptance could lead to a surge in demand and potentially stabilize its price volatility.
Store of Value vs. Medium of Exchange: There's an ongoing debate over whether Bitcoin will primarily function as a long-term store of value (like digital gold) or as a widely used currency for everyday transactions. The outcome of this will significantly shape Bitcoin's trajectory. If Bitcoin stabilizes and becomes more widely accepted, its role as a medium of exchange could become more dominant.
Competition and Innovation: The cryptocurrency landscape is constantly evolving, with new projects vying for attention. Bitcoin's dominance could be challenged by other cryptocurrencies offering greater scalability, privacy features, or innovative use cases. To remain dominant, Bitcoin will need to continue innovating.
The Path to the Future
Bitcoin's future hinges on its ability to overcome these challenges and evolve to meet the changing demands of users and society. It's possible Bitcoin could become a widely accepted global currency, a powerful investment asset, or even both. On the other hand, it could be overshadowed by more efficient and adaptable competitors.
While its journey is still unfolding, Bitcoin's impact on the financial world is undeniable. The price of Bitcoin can be quite volatile, fluctuating rapidly due to an interplay of various factors.
Here are four of the key dynamics that influence Bitcoin's price:
1. Supply and Demand:
Limited Supply: Bitcoin has a hard cap of 21 million coins. This scarcity, combined with growing demand, pushes the price upwards.
Demand Fluctuations: Increased buying and holding drives the price up, while a surge in selling has the opposite effect.
Demand Widening: ETFs and other new demand sources (sovereign wealth funds, institutions) are making their first Bitcoin purchases, increasing the number of holders and active purchasers.
2. Regulatory Environment:
Government Policies: Favorable regulations from governments around the world can build trust and increase adoption, driving demand. Conversely, restrictive regulations or bans can stifle demand and negatively impact the price.
Institutional Adoption: As more large financial institutions and corporations invest in Bitcoin, demand increases, boosting the price.
3. Global Macro Economic Factors:
Economic Uncertainty: In times of economic turbulence, investors might turn to Bitcoin as a potential hedge against inflation or a safe-haven asset, leading to increased demand.
Macroeconomic Trends: Interest rates, inflation, and general economic health can significantly impact risk appetites of investors, influencing their decisions regarding Bitcoin.
4. Technological Advancements and Security:
Network Upgrades: Improvements in Bitcoin's scalability and network security can boost confidence and increase adoption, impacting the price.
Security Breaches: Hacks or security vulnerabilities can erode trust, leading to a potential decrease in demand and price.
Bitcoin is the Breakthrough
Blockchain will become yet another protocol, like e-mail or web — it will disappear into the ambiance like most highly-effective utilities do.
Bitcoin is the breakthrough.
The blockchain acts as the train tracks, providing the foundational infrastructure upon which Bitcoin (the train) operates.
Just as train tracks are laid out meticulously, connecting various points in a network to ensure smooth and efficient travel, the blockchain is a meticulously designed system of blocks (or digital information) linked together in a chronological chain. This infrastructure enables the secure and transparent movement of digital information—in this case, Bitcoin transactions—across a distributed network.
The tracks do not favor any particular train, but they are essential for the operation of any train that wishes to travel on them, ensuring that the system is open, decentralized, and accessible to anyone who wishes to use it.
Bitcoin, on the other hand, represents the train that travels on these tracks. It is the first and most prominent application that utilizes the blockchain infrastructure to transport value from one point to another. Just as a train carries passengers or goods across a network of tracks, Bitcoin transports digital currency between parties, enabling financial transactions without the need for intermediaries. The security and reliability of the blockchain ensure that Bitcoin's journey is smooth and its transactions are immutable and traceable, akin to how the integrity of train tracks ensures the safe and timely arrival of trains at their destinations.
This train’s engine is fueled by the principles of decentralization and digital scarcity — it propels individuals and investors across new landscapes of investment and financial autonomy.
Anyone with an internet connection can participate in the Bitcoin network. You can run a node, mine for Bitcoin, or simply use it as a payment system. This permissionless nature promotes inclusivity and reduces barriers to entry.
Bitcoin facilitates more than just transactions.
It provides a store of value and a currency that is free from central control. Unlike traditional currencies issued and controlled by central banks, Bitcoin operates on a decentralized network. There's no single bank, government, or corporation dictating supply, policies, or transaction approvals. This removes the vulnerability associated with a single point of control or failure.
The Bitcoin network is made up of thousands of nodes (computers) spread globally. These nodes collectively verify transactions and maintain the integrity of the blockchain. This distributed structure ensures no single entity can manipulate the system or impose restrictions on its users.
Because Bitcoin is decentralized, it's incredibly difficult for any authority to censor or block transactions. This enables greater financial freedom, particularly for individuals in countries with oppressive regimes or restrictive financial controls.
Bitcoin is a locomotive that is gaining energy from a growing number of sources, driving coin holders into a decentralized future decoupled from the untenable debtflation ponzi scheme that is Fiat money.
