What Is the Bitcoin Whitepaper?
📌 Key Takeaways
The Bitcoin whitepaper is the very first document that explains how Bitcoin works.
It was published anonymously by Satoshi Nakamoto on October 31, 2008.
This text proposes a new form of money, without banks, secure, and global.
It was published in the midst of the global financial crisis, as a response to a failing system.
The whitepaper remains a foundational document in the world of cryptocurrencies today.
🕰 The Context: A Historic Economic Crisis
In 2008, the world faced a major economic crisis, known as the Great Recession. This crisis was caused by the bursting of the real estate bubble in the United States.
Banks were lending money to people who could not afford to repay. They transformed these risky loans into complex financial products, then resold them to other institutions, such as pension funds.
When borrowers began defaulting, everything collapsed. Banks went bankrupt, millions of people lost their jobs, their homes… yet almost no one responsible was punished.
It was in this context that Satoshi Nakamoto published the Bitcoin whitepaper.
📄 What Does the Bitcoin Whitepaper Contain?
This 9-page document is titled:
“Bitcoin: A Peer-to-Peer Electronic Cash System”.
It explains how to create a secure digital currency, without banks or any central authority.
The whitepaper presents three key ideas:
How Bitcoin transactions work
How the network reaches agreement (consensus)
How to secure the system against attacks
💸 Transactions: Person to Person, Without Intermediaries
In the system proposed by Satoshi, transactions do not go through a bank. Users themselves validate and record payments.
🧠 Simple analogy:
Imagine sending a coin directly to a friend without going through a cashier or ATM. That is what Bitcoin proposes, but on the Internet.
Each user uses a digital signature (created using mathematical formulas) to prove they are the rightful owner of their bitcoins.
These signatures allow validating a transaction without revealing personal information.
🤝 Consensus: How to Prevent Fraud?
A major problem in digital systems is double spending: someone could try to spend the same money twice.
To prevent this, Bitcoin uses a system called Proof of Work, invented by Adam Back.
🔧 Simple analogy:
To write on Bitcoin’s ledger (called the blockchain), you first have to solve a mathematical puzzle.
The first one to solve it earns the right to write… and receives a reward in bitcoins.
This incentivizes participants to behave honestly, because cheating requires a lot of resources… for little chance of success.
🔐 Security: A Strong System… As Long as the Majority Is Honest
Satoshi explains that the network’s security relies on participants’ behavior. If the majority follows the rules, the system works perfectly.
Each new block of transactions is added to a chain (the blockchain) that everyone can see. The “official” version of history is always the longest chain, validated by the majority.
❗ What Happens if Someone Controls More Than 50% of the Network?
This is called a 51% attack. It could allow a group to temporarily manipulate the system. But even in this case:
They could not create bitcoins at will
They could not change the rules of the game, because these rules are coded into the software itself
Satoshi compares this to an unlucky gambler at a casino: the longer they bet without winning, the less chance they have of beating the system.
🧑💻 Who Wrote the Whitepaper?
The whitepaper was signed by Satoshi Nakamoto, a pseudonym. We don’t know if it was:
a man or a woman,
a single person or a group,
or even where they came from.
Online, Satoshi claimed to be a Japanese man, but everything suggests they wanted to remain anonymous.
They actively participated in the project from 2009 to 2011, then disappeared, entrusting the management of bitcoin.org to another developer, Martti Malmi.
📚 Why Is This Document So Important?
The Bitcoin whitepaper is the first text to propose a viable digital currency, usable by everyone, without going through a bank.
Before this, several cryptographers had attempted to create similar systems, but none had succeeded:
In 1998, Wei Dai imagined a project called B-Money. It laid good foundations (like digital signatures or peer-to-peer exchanges), but the system remained theoretical.
The same year, Nick Szabo thought of Bit Gold, another project very close to Bitcoin. But some parts of the system were too centralized (certain servers had to be trusted).
Szabo himself acknowledged that Satoshi had corrected an important weakness in his idea.
Thanks to Satoshi, all these ideas were gathered, improved, and made concrete. Bitcoin thus became the first truly functional cryptocurrency.
🎯 Key Points to Remember
The Bitcoin whitepaper is the founding text of the Bitcoin system.
It was published in 2008, in the midst of an economic crisis, as an alternative to banks.
It explains how to create a digital currency that is reliable, secure, and open to everyone.
This document paved the way for all modern cryptocurrencies.
Even though we still don’t know who Satoshi Nakamoto is, their invention has marked the history of finance.

Bitcoin FAQ

Is it a good time to buy Bitcoin?
It is difficult to predict market movements. That’s why many investors use DCA (Dollar Cost Averaging): you regularly buy the same amount, regardless of the price, which reduces the impact of fluctuations. To learn more about recurring investment, check out our dedicated article.
What influences the price of Bitcoin?
Bitcoin’s price is influenced by many factors: supply and demand, investor confidence, global adoption, macroeconomic news, as well as regulations and technical developments of the network.
Bitcoin remains a volatile asset, so it is essential not to invest money you cannot afford to lose and to consider your investment as a long-term commitment.
Is my Bitcoin investment locked?
On the blockchain and through exchanges, you can buy and sell your bitcoins at any time without any lock-up period.
With Fibo, you can buy bitcoin on a recurring basis every week or every month and sell it whenever you want.
What is the minimum amount to invest?
Although the price of a full bitcoin may seem high, it is not necessary to buy a whole one. Bitcoin is divisible down to the eighth decimal, and its smallest unit is called a satoshi. This means you can buy fractions of bitcoin, even with just €1.
At Fibo, you can invest in diversified portfolios designed by our experts, starting from €50 if you choose a recurring transfer.
