Bitcoin is a digital currency created in 2009 by Satoshi Nakamoto. His idea was to create a currency that could be created and held electronically, a currency that could not be centrally controlled by a single entity. Now in 2015 we can say with certainty that he succeeded.
The CPU era
In the beginning Bitcoin could be mined using a desktop CPU. This allowed people to mine Bitcoin in the comfort of their home using their computer. They mostly solo mined to sustain and make the network bigger. These people were mostly involved with the technology sector. Many of them really believed this could go very far, and that it was a very promising technology that combined ideas created in the past. Satoshi managed to bundle these ideas together to form Bitcoin.
The GPU era
After the first CPU miners and as the network was growing at a fast pace the next logical step was to move from CPU mining to GPU mining. This allowed even more people to mine with much faster hardware compared to CPU due to parallel processing and multi GPU systems that allowed the network hash rate to grow exponentially, providing better stability in transaction times and making it much harder for someone to perform the infamous 51% attack.
ASIC hardware enters the game
ASIC is an application specific integrated circuit that is produced and programmed for the sole purpose of mining Bitcoin. Modern Bitcoin ASIC include microprocessors, memory blocks including ROM, RAM, EEPROM, flash memory and other large building blocks. Such an ASIC is often termed a System on a Chip (SOC). They can reach speeds almost unimaginable before by CPU and GPU miners. These devices are sold by mining companies like 21 Inc.
Evolution of the Bitcoin ecosystem
Mining allowed people and companies to build services and products that used the blockchain. Most notable examples are Bitcoin exchanges and online marketplaces for a variety of products. Online stores and companies like Microsoft and Dell now accept Bitcoin.
The 21 Bitcoin Computer
Nowadays a lot of services and products are flooding the market, but one has the power the harness the full power of the block chain. The 21 Bitcoin Computer is the first computer with native hardware and software support for the Bitcoin protocol allowing you to use the hardware in more than one ways.
The device is capable of mining using a dedicated ASIC chip with a hash calculation rate of 50 to 125 Gigahashes per second. You can buy digital goods with the constant stream of Bitcoin mined by a 21 Bitcoin Chip and also sell anything to anyone for bitcoin with the built-in 21 Micropayments Server. Using the 21 Bitcoin Computer you can easily build bitcoin payable applications, services, and devices and last but not least it can operate as a standalone computer, or connect to any Mac, Windows, or Linux machine.
The package includes a powerful command line interface, an 128 GB SD card loaded with a full copy of the blockchain, a suite of pre-configured Bitcoin-dependent software and a WiFi adapter, a laptop cable, a Raspberry Pi 2, and a power supply.
