Le Bitcoin (BTC) is the world's first decentralized cryptocurrency. Created in 2009, it has now become a essential digital asset which attracts both investors and the curious. But what exactly is Bitcoin?
Who invented it? Why was it created? And how does it differ from other cryptocurrencies like Ethereum, Ripple, or Solana?
In this article, we will explain everything, simply.
Who invented Bitcoin?
Bitcoin was invented in 2008 by a person (or group of people) under the pseudonym Satoshi NakamotoHis identity remains a mystery.
In the whitepaper “Bitcoin: A Peer-to-Peer Electronic Cash System”, published in October 2008, Satoshi describes a revolutionary solution:
👉 A system of decentralized electronic payment, which allows two people to exchange value without going through a bank or trusted third party.
The network officially launched in January 2009, with the creation of the first blockchain block: the "genesis block".
Why was Bitcoin created?
Bitcoin was born in a particular context: the 2008 financial crisis.
This crisis has exposed the fragility of the global banking system, which is dependent on central banks and governments. Bitcoin was designed as a alternative to the traditional financial system :
- Independent banks and states
- Total transparency thanks to the blockchain (all transactions are public)
- Limited offer to 21 million bitcoins (versus infinitely printed fiat money)
- Peer-to-peer system (P2P) without intermediary
In summary: Bitcoin is both a digital currency and store of value, designed to give power back to individuals.
How does Bitcoin work?
Bitcoin works through a technology called blockchain.
👉 Blockchain is a public, tamper-proof ledger that records all transactions.
Some key concepts:
- Transactions are validated by Minors, via a consensus mechanism called Proof-of-Work.
- Mining secures the network and allows new bitcoins to be issued.
- The supply is programmed to decrease over time (halvings), ensuring scarcity.
What is the history of Bitcoin?
- 2009 : Official launch, first transaction between Satoshi Nakamoto and Hal Finney.
- 2010 : First purchase with Bitcoin: 2 pizzas for 10 BTC (famous “Bitcoin Pizza Day”).
- 2011-2013 : Growing adoption, emergence of other cryptos like Litecoin.
- 2017 : Price Explodes to Nearly $20 – The General Public Discovers Bitcoin.
- 2021 : New historic record around $69, adopted by El Salvador as legal tender.
- Today : Bitcoin is recognized as a global store of value, sometimes compared to digital gold.
Bitcoin vs. other cryptocurrencies
Since the creation of Bitcoin, more than 20 cryptos have emerged. But none have the same history or security as BTC. You've probably heard of these cryptocurrencies, for example:
- Ethereum (ETH) : oriented towards the smart contracts and decentralized applications (DeFi, NFT).
- Ripple (XRP) : designed for fast international payments.
- Left (LEFT) et Polygon (MATIC) : focus on speed and blockchain applications.
- Stablecoins (USDT, USDC) : stable cryptos indexed to the dollar, but dependent on centralized entities.
👉 The major difference: Bitcoin is truly decentralized, scarce, and has no identifiable founder today. This is what makes it a unique asset.
