ArtForz.
Discover the forgotten story of this mysterious pioneer, who single-handedly controlled 25% of the Bitcoin network in 2010.

When Bitcoin was worth almost nothing
In 2010, Bitcoin was still extremely marginal.
Satoshi Nakamoto’s whitepaper was just over a year old, and #BTC was worth barely $0.01.
Mining difficulty was ridiculously low, and the block reward was still 50 BTC per block.
The first users were cypherpunks, libertarians, and nerds, mining with… their CPU.
At the time, a simple desktop PC was enough to mine blocks.
It was in this setting that a new username appeared on Bitcointalk in July 2010: ArtForz.
No one knew it yet, but that name would become a legend.

A broke engineer with a PayPal problem
Before Bitcoin, ArtForz was far from what you’d call a financial tycoon.
He was an electrical engineer, comfortable with hardware, circuits, and graphics cards.
He loved computers, video games, and complex systems.
To make ends meet, he “farmed” virtual currencies in video games and then sold them for real money.
Until the day PayPal froze his account because of these activities.
The message hit hard: the traditional financial system can cut off your access to money… with a single click.
At the same time, a new concept was circulating on certain internet forums:
a currency that no company, no bank, no platform could censor Bitcoin.
ArtForz immediately grasped the power of the idea, and above all, he quickly saw that Bitcoin could be mined.

From a laptop to the “ArtFarm”
In 2010, it was still possible to mine on a laptop or a simple desktop computer.
Early enthusiasts discovered that GPUs (graphics cards) were far more efficient than CPUs for calculating the hashes required by Proof of Work.
Officially, Satoshi Nakamoto hoped for a “gentleman’s agreement” to avoid triggering a hardware arms race too quickly, in order not to kill network decentralization.
But in July 2010, ArtForz decided to shift into high gear and began mining with GPUs.
Very quickly, he built what is considered one of the world’s very first GPU mining farms: the “ArtFarm.”
In just one month, ArtForz already controlled around 10% of the Bitcoin network’s total computing power.
By the end of 2010, his farm reached as much as 25% of the total network hashrate.
ArtForz stacked dozens of GPUs in cardboard boxes to keep them more or less ventilated, in a kind of handcrafted chaos halfway between a laboratory and a geek’s attic.
One day, he reported on Bitcointalk that he had mined 1,700 BTC in 6 days.

409,650 Bitcoin: a treasure mined in indifference
With his ArtFarm, ArtForz mined block after block.
Cross-checked estimates suggest a total of around 409,650 BTC mined by ArtForz during this period an astronomical amount.
ArtForz sold a large portion of his BTC as the price began to rise, but according to several accounts, he still kept around 50,000 BTC.

The bug that could have killed Bitcoin
ArtForz was not just an opportunistic miner he was also a highly skilled programmer and a security expert.
In July 2010, he discovered what would later be described as one of the most dangerous bugs in Bitcoin’s history: a flaw in the way transaction scripts were validated, related to what would be called the OP_RETURN bug.
The vulnerability could have allowed someone to spend BTC from any wallet without owning the private keys.
ArtForz could have exploited it, but instead he chose to report the issue directly to Satoshi Nakamoto and the developers.
The problem was fixed urgently.
Authors such as Nathaniel Popper, in Digital Gold, emphasize this moment: the fact that ArtForz did not use the exploit to enrich himself is presented as proof that the system’s incentives were already working.
His own coins would have become worthless if the protocol had lost all credibility.
That day, an anonymous miner very likely saved #bitcoin .

The hardware arms race: FPGA, ASIC, and the fall of the ArtFarm
But ArtForz’s dominance did not last forever.
As Bitcoin gained popularity, new miners wanted their share of the action.
Mining moved from CPU to GPU, then to FPGA (reprogrammable circuits), and finally to ASICs (specialized chips designed for crypto mining).
ASICs quickly made desktop PCs obsolete, and GPUs almost useless for mining Bitcoin.
ArtForz tried to survive by designing his own custom mining chips, which temporarily allowed him to climb back to around 5% of the network hashrate.
But by August 2011, despite his efforts, ArtForz’s share fell below 1% of the total hashrate.
He could no longer compete with massive farms and warehouses filled with metal racks and industrial fans.

The Scrypt controversy
Faced with this growing centralization, ArtForz refused to give up.
If hardware was becoming too powerful, then perhaps the solution was to change… the algorithm itself.
He turned to Scrypt, a cryptographic function designed in 2009 by Colin Percival to secure file backups.
In 2011, ArtForz implemented Scrypt in a new cryptocurrency: Tenebrix, often cited as the first crypto to use Scrypt as its proof-of-work algorithm.
Litecoin, launched in October 2011, also adopted Scrypt for its Proof of Work.
In the Litecoin whitepaper, the developers wrote plainly:
“We humbly offer our great thanks to ArtForz for the implementation.”
But the story doesn’t end there. A controversy erupted over the possible use of Scrypt by ArtForz to mine 150 times faster with GPUs.
Part of the community began to suspect that ArtForz had kept a hidden technical advantage for himself.
ArtForz denied ever intending to deceive anyone.

The disappearance
After 2012, traces of ArtForz became rare.
His username appeared on forums related to video game mods, notably for Minecraft and Kerbal Space Program.
But no more posts on Bitcointalk.
ArtForz went silent.
Some believe he still holds 50,000 BTC in a cold wallet…
Others think he sold everything or lost it all…
No one really knows.

But who was ArtForz, really?
Very little is known about him.
A solitary engineer.
A coder brilliant enough to spot a fatal bug and ethical enough not to exploit it.
A pioneer who accumulated 409,650 $BTC at a time when no one was yet watching Bitcoin price charts.
And then… complete silence.
Shortly after this controversy, he almost completely stopped posting on Bitcointalk.
