Mapping the Major Bitcoin Forks
The emergence of Bitcoin took the world by storm through its simplicity and innovation. Yet, plenty of confusion remains around the term itself.
The Bitcoin blockchain—not to be confused with the bitcoin cryptocurrency—involves a vast global network of computers operating on the same distributed database to process massive volumes of data every second.
These transactions tell the network how to alter this distributed database in real-time, which makes it crucial for everyone to agree on how these changes should be applied. When the community can’t come to a mutual agreement on what changes, or when such rule changes should take effect, it results in a blockchain fork.
Today’s unique subway-style map by Bitcoin Magazine shows the dramatic and major forks that have occurred for Bitcoin. But what exactly is a Blockchain fork?
Types of Blockchain Forks
Forks are common practice in the software industry and happen for one of two reasons:
- Split consensus within the community
These forks are generally disregarded by the community because they are temporary, except in extreme cases. The longer of the two chains is used to continue building the blockchain.
- Changes to the underlying rules of the blockchain
A permanent fork which requires an upgrade to the current software in order to continue participating in the network.
There are four major types of forks that can occur:
1. Soft Forks
Soft forks are like gradual software upgrades—bug fixes, security checks, and new features—for those that upgrade right away.
These forks are “backwards compatible” with the older software; users who haven’t upgraded still have access to the network but may not be able to use all functionality in the current version.
2. Hard Forks
Hard forks are like a new OS release—upgrading is mandatory to continue using the software. Because of this, hard forks aren’t compatible with older versions of the network.
Hard forks are a permanent division of the blockchain. As long as enough people support both chains, however, they will both continue to exist.
The three types of hard forks are:
Scheduled upgrades to the network, giving users a chance to prepare. These forks typically involve abandoning the old chain.
Caused by disagreements in the community, forming a new chain. This usually involves major changes to the code.
- Spin-off Coins
Changes to Bitcoin’s code that create new coins. Litecoin is an example of this—key changes included reducing mining time from 10 minutes to 2.5 minutes, and increasing the coin supply from 21 million to 84 million.
3. Codebase Forks
Codebase forks copy the Bitcoin code, allowing developers to make minor tweaks without having to develop the entire blockchain code from scratch. Codebase forks can create a new cryptocurrency or cause unintentional blockchain forks.
4. Blockchain Forks
Blockchain forks involve branching or splitting a blockchain’s whole transaction history. Outcomes range from “orphan” blocks to new cryptocurrencies.
Splitting off the Bitcoin network to form a new currency is much like a religious schism—while most of the characteristics and history are preserved, a fork causes the new network to develop a distinct identity.
Summarizing Major Bitcoin Forks
Descriptions of major forks that have occurred in the Bitcoin blockchain:
- Bitcoin / Bitcoin Core
The first iteration of Bitcoin was launched by Satoshi Nakamoto in 2009. Future generations of Bitcoin (aka Bitcoin 0.1.0) were renamed Bitcoin Core, or Bitcore, as other blockchains and codebases formed.
A codebase fork of Bitcoin. Developers released a hard fork protocol called Segwit2x, with the intention of having all Bitcoin users eventually migrate to the Segwit2x protocol. However, it failed to gain traction and is now considered defunct.
- Bitcoin ABC
Also a codebase fork of Bitcoin, Bitcoin ABC was intentionally designed to be incompatible with all Bitcoin iterations at some point. ABC branched off to form Bitcoin Cash in 2017.
- Bitcoin Gold, Bitcoin Diamond, Other Fork Coins
After the successful yet contentious launch of Bitcoin Cash, other fork coins began to emerge. Unlike the disagreement surrounding Bitcoin Cash, most were simply regarded as a way to create new coins.
Some of the above forks were largely driven by ideology (BTC1), some because of mixed consensus on which direction to take a hard fork (Bitcoin ABC), while others were mainly profit-driven (Bitcoin Clashic)—or a mix of all three.
Where’s the Next Fork in the Road?
Forks are considered an inevitability in the blockchain community. Many believe that forks help ensure that everyone involved—developers, miners, and investors—all have a say when disagreements occur.
Bitcoin has seen its fair share of ups and downs. Crypto investors should be aware that Bitcoin, as both a protocol and a currency, is complex and always evolving. Even among experts, there is disagreement on what constitutes a soft or hard fork, and how certain geopolitical events have played a role in Bitcoin’s evolution.
Mapped: Cryptocurrency Regulations Around the World
Cryptocurrency regulations are essential for the future of digital finance, making it more attractive for businesses, banks, and investors worldwide.
Mapped: Cryptocurrency Regulations Around the World
Following the unprecedented cryptocurrency boom in 2017, investors and governments alike could no longer ignore the growth of decentralized finance.
The world has become increasingly fascinated with cryptocurrencies and the ways they are enabling greater access, such as being able to send funds to remote places or securing capital for small businesses.
To aid this, cryptocurrency regulations are being slowly introduced into global financial markets. Regulations help to monitor these emerging digital currencies, and to allow for clearer guidelines and a measure of security.
The Regulatory Landscape
Today’s graphic from ComplyAdvantage maps out major regulatory cryptocurrency and exchange landscapes around the world, showing how sentiments towards digital currencies are evolving.
To do this, ComplyAdvantage measured cryptocurrency regulatory environments using their own Light-to-Tight scale, based on the following criteria:
- Cryptocurrencies and exchanges status? (Ban = 3 points, Regulated = 2 points, Grey Area = 1 point)
- Cryptocurrency considered legal tender? (Yes = 1 point, No = 0 points)
- Planned legislation to increase crypto regulation? (Yes = 1 point, No = 0 points)
Which jurisdictions have the strictest and most relaxed regulations for cryptocurrencies?
Regulations by Region
Global attitudes towards the rise of cryptocurrencies have shifted greatly over the past few years. While the term cryptocurrency is a bit of a misnomer, some countries do consider digital currencies legal tender, with many viewing cryptocurrencies as commodities.
Below is a table of the major countries that are pursuing cryptocurrency regulations:
|Country||Cryptocurrencies||Exchanges||Initial Coin Offerings (ICOs)|
|Australia||Legal; treated as property||Legal, must register with AUSTRAC||Regulated|
|Switzerland||Legal; generally accepted as payment||Legal, regulated by SFTA||Regulated|
|Malta||Not legal tender||Legal, regulated under the VFA Act||Regulated|
|Estonia||Not legal tender||Legal, must register with the Financial Intelligence Unit||Regulated|
|Gibraltar||Not legal tender||Legal, must register with the GFSC||Regulated|
|Luxembourg||Not legal tender||Legal, must register with the CSSF||Regulated|
|Canada||Not legal tender; some retailers accept as payment||Legal, regulation varies by province; final federal regulations expected late 2019||Regulated|
|Mexico||Legal, accepted as payment in some contexts||Grey area; first crypto exchange in opened mid 2019||Regulated|
|Lithuania||Not legal tender||Legal, must register with the Lithuanian Finance Ministry||Grey area|
|United States||Not legal tender; some retailers accept as payment||Legal, regulation varies by state; SEC expected to publish updated crypto regulations late 2019||Grey area|
|UK||Not legal tender; considered assets||Legal, registration requirements with FCA||Grey area|
|Russia||Not legal tender||Grey area; regulations to be determined by the end of 2019||Grey area|
|Japan||Legal; treated as property||Legal, must register with the Financial Services Agency||Grey area|
|Nigeria||Legal||Grey area; regulations upcoming from Central Bank of Nigeria||Grey area|
|Singapore||Not legal tender||Legal, no registration required||Grey area|
|South Korea||Not legal tender||Legal and regulated, must register with FSS||Banned|
|India||Not legal tender; digital rupee may be in the works||Effectively illegal, but global and federal regulations being considered||Banned|
|China||Bitcoin considered property; all other cryptocurrencies banned||Illegal, but a global regulatory framework being considered||Banned|
Japan has one of the most progressive regulatory climates for cryptocurrencies, widely considering bitcoin as legal tender and passing a law in mid-2017 recognizing cryptocurrencies as legal property. In late 2018, Japan also approved self-regulation for the crypto industry.
By contrast, China currently has one of the most restrictive environments in the world for cryptocurrency. China banned bitcoin transactions in 2013, as well as ICOs and crypto exchanges in 2017─though many have found workarounds through sites not yet firewalled.
Cryptocurrency and exchange regulations in the EU are determined by individual member states, and are considered legal across the bloc.
Digital currency offers great promise, through its ability to reach people and businesses in remote and marginalized regions.
—Christine Lagarde, Managing Director of IMF
Perhaps unsurprisingly, Switzerland has one of the most open climates for cryptocurrencies and exchanges in Europe. In 2016, the city of Zug, known as “Crypto Valley”, started accepting bitcoin as payment for city fees. Swiss Economics Minister Johann Schneider-Ammann announced his goal in 2018 to make Switzerland the world’s first “crypto-nation”.
Both Canada and the U.S. take a similar approach to cryptocurrency legislation at the federal level, as both countries view cryptocurrencies as securities. However, provincial and state regulations differ widely in their taxation requirements of profits from crypto investments.
Regulations throughout Latin and South America run the full legislative spectrum.
- Bolivia: unilateral ban on cryptocurrencies and exchanges
- Ecuador: the first country to launch its own token; ban on all cryptocurrencies aside from its government-issued SDE token (Sistema de Dinero Electrónico = electronic money system)
- Mexico, Argentina, Brazil, Chile: cryptocurrencies widely accepted as payment
- Venezuela: cryptocurrencies widely accepted; this makes sense, considering the economic crisis and subsequent freefall of the bolívar
The Importance of Cryptocurrency Regulations
Cryptocurrency’s journey is the story of a technology rapidly outpacing the laws that govern it.
Governments around the world are keenly aware of this problem. Members of the G20 published a request in June 2019 for a global regulatory framework for cryptocurrencies to be implemented to better manage the benefits and challenges that cryptocurrencies bring.
Regulation for both cryptocurrencies and crypto exchanges is essential for the future of digital finance─bringing legitimacy to the digital financial market, and making it more attractive for new businesses, established banks, and investors worldwide to more easily conduct business within this emerging ecosystem.
The Beginning of a Bitcoin Bull Run?
After 15 months of losses and stagnation, Bitcoin has made a miraculous recovery — going on a 150% bull run since its lows in December 2018.
The Beginning of a Bitcoin Bull Run?
After 15 months of losses and stagnation, Bitcoin has made a miraculous recovery — rising more than 150% from its lowest point in December 2018.
In its heyday, Bitcoin had surpassed $10,000 in early December 2017, before briefly crossing the $20,000 mark for a single day on December 17th. A year later, the digital currency had fallen back to Earth, dropping below $3,200.
Now that the dust of that wild speculative frenzy has settled, Bitcoin is back on the upswing. What could be causing this most recent surge in growth?
We look at four possible explanations for the Bitcoin bull run, as originally outlined by Aaron Hankin at MarketWatch:
Bitcoin has seen several technical milestones this year, such as surpassing the psychological barrier of $5,000 in early 2019, breaking the 200-day moving average, and scoring the golden cross (when the 50-day moving average crosses above the 200-day moving average).
Bitcoin is experiencing a steady increase in adoption across several markets. The term Bitcoin has become a household name — even if people don’t understand what it does, they know what it is.
Companies such as Starbucks, Microsoft, and Amazon, and Nordstrom are looking for ways to integrate cryptocurrencies into daily transactions for faster payment clearance, innovative rewards programs, and efficient customer service interactions.
Bitcoin has possibly seen a shift in public perception. There have been fewer negative articles about Bitcoin and cryptocurrencies, and the news stories that are negative no longer have as big of an impact as they once did.
When Binance announced hackers stole $40 million in bitcoin and when accusations of an $850-million cover-up were leveled against Bitfinex and Tether, the Bitcoin bull run barely flinched and continued to climb.
Wavering Gold Investment
Investor confidence in gold has been more stagnant in recent times. To capitalize on this, Grayscale Investments (of Digital Currency Group) posted a campaign in May 2019 promoting Bitcoin as an ideal alternative to gold because it is borderless, secure, and more efficient for storing value.
Despite the World Gold Council’s response denying those claims, the Grayscale Bitcoin Trust saw OTC Markets Group’s highest trading volumes five days later.
Where to from here?
After a long skid, it appears Bitcoin is showing signs of life again. Bitcoin’s price can be highly volatile, so it remains to be seen whether this is the beginning of a bull run, or whether this is just another bump in the roller coaster ride.
Editor’s note: The price of Bitcoin has fallen to $7,100 at time of publishing and will likely continue to experience extreme volatility. However, even at a price of $7,100, this is still a 120% increase from lows in Dec 2018. As well, an earlier version of this graphic had incorrect dates on the timeline. That has now been corrected.
