History of BitcoinThe origins and history of Bitcoin

How did Bitcoin actually come about? And what has happened since then? To understand that properly, we first go back to the early nineties. After that we follow the history step by step up to today.

Bitcoin did not appear out of nowhere. Its roots lie in the 1980s and 1990s, when a group of cryptographers who called themselves the cypherpunks thought about how to protect privacy and money with mathematics instead of institutions.

In 1989 David Chaum came up with DigiCash: the first digital money based on cryptography. In 1997 Adam Back proposed hashcash, a system that curbs spam with proof-of-work. In 1998 Wei Dai and Nick Szabo independently described b-money and bit gold, early ideas for decentralised electronic money.

Each proposal solved part of the puzzle, but no system worked at scale. What was missing was a way to solve the double-spending problem without a central server.

In October 2008, in the middle of the global financial crisis following the collapse of Lehman Brothers, someone under the pseudonym Satoshi Nakamoto published a nine-page document: the Bitcoin whitepaper. The central question: can we create electronic money without needing banks?

Satoshi's answer combined ideas from the cypherpunks with a new mechanism: the blockchain. Every transaction goes into a block, blocks are linked into a chain, and the whole network validates what is real. A central authority is not needed.

The first block

On 3 January 2009 Satoshi mined the first block, known as the Genesis Block. In it he left a message that can still be read today: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks". A direct reference to the bank bailout in the United Kingdom.

On 12 January 2009 Satoshi sent 10 bitcoin to programmer Hal Finney: the first real transaction between two people on the network.

To this day, no one knows who Satoshi is. In 2010 he disappeared from the forums and was never seen again.

In the early years Bitcoin was an experiment among programmers. It had barely any value: on 22 May 2010 Laszlo Hanyecz paid 10,000 BTC for two pizzas. That day is now celebrated worldwide as Bitcoin Pizza Day.

The first exchanges appeared shortly after. Mt. Gox, launched on 18 July 2010, handled 70% of the world's bitcoin volume at its peak. The price rose from a few cents in 2010 to more than 1,000 dollars in 2013.

The fall of Mt. Gox

In February 2014 Mt. Gox went bankrupt. A hack had cost customers 850,000 BTC. For many it was a hard lesson: if you don't control your keys, you don't control your coins. That is where the saying "not your keys, not your coins" comes from.

After the fall of Mt. Gox, the ecosystem matured. Exchanges with better security emerged, hardware wallets to store coins offline appeared, and regulators started to set up frameworks.

Recent milestones

• 2017: First big bull market. In one year Bitcoin rises from 1,000 to almost 20,000 dollars. On 1 August 2017 the network splits into bitcoin (with SegWit) and bitcoin cash (larger transaction blocks).
• 2018: The Lightning Network goes live: a second layer on top of the blockchain that makes lightning-fast micro-transactions with minimal fees possible.
• 2020-2021: Companies such as MicroStrategy and Tesla add Bitcoin to their balance sheets. El Salvador makes Bitcoin official legal tender.
• 2024: The US SEC approves the first spot Bitcoin ETFs, opening the door for institutional investors.
• 2024 in the EU: MiCA comes into force, the legal framework that regulates crypto across the entire European Union.

Bitcoin today

Bitcoin has grown from an experiment among programmers into a global financial infrastructure with millions of users. The network still processes a block every ten minutes, just like in 2009.
