The Chronicles of Cryptocurrency Mining

Preface

Since the first Bitcoin block was "mined" on January 3, 2009, the term "mining" has taken on an additional meaning related to digital currency.

Looking back at the development history of the entire mining industry over the past decade, Bitmain, Canaan Creative and Ebang International have gradually developed into leading companies in the production of mining machines amid fierce competition in the industry. In May, June and September of this year, the three companies successively submitted prospectuses to the Hong Kong Stock Exchange.

In order to have a better computing power, the mining machine has undergone several iterations and updates: Butterfly Miner, Panda Miner, Watermelon Miner, Ant Miner, Avalon Miner, Wingbit Miner...

The battle for computing power between mining pools has never stopped. Since the first mining pool SlushPool, the computing power share of each mining pool has been a constant game of rise and fall. Today, Bitmain's BTC mining pool and AntPool have become two computing power giants in the mining pool with the support of the Ant series of mining machines.

Explanation of terms

Hashrate

Computing power is one of the important indicators to measure the computing speed of a mining machine. The higher the computing power, the higher the probability of "mining" cryptocurrency.

Common computing power units:

1KH/s, which means 1,000 hash function operations can be performed per second;

1MH/s, can perform 10^6 hash function operations per second;

1TH/s, which means 10^12 hash function operations can be performed per second;

1GH/s, which means 10^9 hash function operations can be performed per second;

1PH/s, which means 10^15 hash function operations can be performed per second;

1EH/s, which means 10^18 hash function operations can be performed per second.

“The historical computing power of the entire Bitcoin network has a peak of nearly 60EH/s”

FPGA

FPGA is the abbreviation of "Field Programmable Gate Array", which is a kind of integrated circuit. Users can reconfigure the logic modules and I/O modules inside the FPGA to realize the user's logic.

ASIC

ASIC is the abbreviation of "Application Specific Intergrated Circuits", which refers to integrated circuits designed and manufactured to meet specific user requirements and the needs of specific electronic systems.

Mining Pools

A mining pool is a collection of computing power. When everyone concentrates their computing power in the mining pool, the probability of mining a block will be greatly increased. Finally, the profits will be distributed according to each person’s share of computing power.

2009

The founding year of the blockchain industry chain

January

The first block was mined

At 18:15 on January 3, 2009, on a small server in Helsinki, Satoshi Nakamoto created the Genesis Block and left a message in it: "On January 3, 2009, the Chancellor of the Exchequer was on the verge of implementing a second round of emergency bank bailouts."

2010

GPU replaces CPU mining

January

Yibang Communication Technology Co., Ltd. was established

Hu Dong founded Yibang Communication Technology Co., Ltd., whose main business is system integration of communication engineering and network engineering and design of integrated circuits.

The computing power of GPU reaches 9MH/S, while the computing power of CPU is only about 1KH/s

The computing power of the GPU (graphics processing unit) at this time is about 9,000 times that of the CPU (central processing unit).

July

Miner ArtForz realized mining with personal OpenCL GPU

Bitcoin mining has entered the era of GPU mining, and miners have begun to actively look for ways to increase computing power.

September

GPU mining Bitcoin code appears, breaking the CPU mining convention

Jeff Garzik paid 10,000 BTC (about $600 at the time) to open source the GPU optimization software.

December

The world's first mining pool Slushpool was established

Marek Palatinus created the first mining pool, slushpool, which is known as the "quagmire". Slushpool is affiliated with SatoshiLabs in Prague, the capital of the Czech Republic. In addition to the mining pool slushpool, the main projects operated by SatoshiLabs include Bitcoin wallets TREZOR and myTREZOR, as well as Coinmap, a tool for querying Bitcoin payment merchants.

2011

“Pumpkin Zhang” and the FPGA Mining Era

"Pumpkin Zhang" developed a Bitcoin FPGA mining machine in his spare time

In 2011, Bitcoin and blockchain technology were still emerging technologies in the early stages of development. Zhang Nangeng, who was a graduate student at Beihang University at the time, used his spare time to develop an FPGA mining machine that could mine Bitcoin. Since it was much more efficient than GPU mining, it was very popular, and "Pumpkin Zhang" also made his first pot of gold.

2012

First mining machine crowdfunding

May

The first crowdfunding of mining machines, Butterfly Miner started crowdfunding

The Butterfly Miner is developed by the American Butterfly Labs, using 65nm chip technology and a computing power of 5GH/S. The Butterfly Miner is available in the form of futures and is expected to be shipped in March 2013.

The Watermelon FPGA Miner is Born

The FPGA mining machine was designed by a technology enthusiast in Guilin. Because of the Guilin watermelon frost, it is referred to as the watermelon mining machine. The computing power is 1.6GH/s.

August

FriedCat starts crowdfunding ASIC mining machines

2013

The era of ASIC mining is coming

January

FC Stocks Start Paying Dividends

The first dividend of FC's stock was paid on January 19, 2013. FC's stock is divided into three categories: direct stock, transfer stock and split stock. Direct stock is directly registered with a BTC wallet address, and each address corresponds to a certain number of shares. When distributing dividends, FC will directly send BTC to the corresponding wallet address. Transfer stock is not a direct stock, and is usually purchased by the operator of the trading website, and then traded on the trading website at the same amount. Because its dividend needs to be transferred, it is called transfer stock. Each split stock is equivalent to 1% of the direct stock. These split shares can only receive 95% of the dividends, and 5% is deducted as management fees.

The first commercial ASIC mining machine is launched, and the ASIC mining era has arrived

In January 2013, the 60GH/s mining machine developed by the founding team of Avalon was accepted for pre-order, and the world's first commercial Bitcoin ASIC mining machine was delivered that month. The emergence of Avalon ASIC mining machine completely subverted the Bitcoin mining industry, opened the second industrial upgrade, and heralded the advent of the ASIC mining era.

March

Butterfly Miner failed to deliver on schedule, and large-scale refund requests began to appear

Due to its computing power advantage and attractive price, Butterfly Miner attracted tens of thousands of orders during the crowdfunding stage. However, Butterfly did not fulfill its promise a few months later, which triggered a large-scale refund wave. Although Butterfly began to ship after July 2013, it was completely unable to meet the computing power requirements at the time, and miners suffered huge losses. For a time, Butterfly became notorious.
