A History of Bitcoin Soft Forks and Hard Forks

Want create site? Find Free WordPress Themes and plugins.

Brief History of Bitcoin

Bitcoin was the first cryptocurrency, which was launched in 2009 by a mysterious developer, with a name “Satoshi Nakamoto.” Since the creation of Bitcoin, it has inspired thousands of other cryptocurrencies (generally called altcoins) and has gained an enormous acceptance across the world.

bitcoin blockchain

Though some altcoins have copied some aspects from the original concept of Satoshi, other altcoins also made significant development on the Bitcoin model. However, in some cases, some altcoins are just a copy of bitcoin and have the similar underlying program – but at the same time, they are a bit different from the original Bitcoin. In such cases, the bitcoin blockchain should undergo a procedure which is called “forking.”

Forking

  • In forking process, Bitcoin blockchain divided itself into two distinct entities.
  • Through forking, numerous cryptos with a similar name to Bitcoin were generated, including; bitcoin gold and bitcoin cash.
  • It may be a bit difficult for a casual investor to differentiate amid these cryptos and to plan the dissimilar hard forks on a timeline.

What is Genesis Block?

  • After Bitcoin was created, the first block was referred to as “Genesis Block.” It was mined on the Bitcoin blockchain by Satoshi.
  • Satoshi made many changes to the Bitcoin network in this process and those changes have now become even more complex as the userbase of Bitcoin has fully-fledged.
  • Not one can regulate when and how Bitcoin should upgrade, and this makes the entire process of changing/updating the system a little bit more complex.
  • Even after the creation of Genesis Block, a number of hard forks still existed.
  • Hard fork included the upgrading of software executing bitcoin and its mining processes.
  • Once a software is upgraded by a user, that software version discards all other transaction from older software and generates a new branch of the bitcoin blockchain.
  • However, users who use the older software are still going to continue to process transactions, henceforth, there’d be a similar set of transactions going on across two different Blockchains.

Bitcoin XT

  • This is one of the most notable Bitcoin hard forks.
  • In 2014, Mike Hearn made the software for integrating some of the new features that he proposed.
  • At that time, Bitcoin allowed only 7 transactions-per-second.
  • Bitcoin XT was intended to allow 24 transactions-per-second.
  • Bitcoin XT primarily experienced a great success after its launch, with almost 1,000 nodes running its software (back in 2015).
  • However, just after few months, users lost interest in Bitcoin XT, making it ‘doomed to die.’
  • Even though Bitcoin XT is officially available today, but it has visibly tumbled out of the errand of crypto community.

Bitcoin Classic

  • After Bitcoin XT failed, few cryptocurrency community members demanded an increase in the block sizes.

To accomplish this goal, Bitcoin Classic was created in 2016.

  • Unlike Bitcoin XT, Bitcoin Classic intended to raise block size to only 2 megabytes.
  • Just like Bitcoin XT, Bitcoin Classic also saw initial interest with almost 2,000 nodes for few months in 2016.
  • Bitcoin Classic still exists today and has gained a strong support from some developers.

SegWit

  • In 2015, Bitcoin core developer, Peter Wuille introduced the idea of SegWit (Segregated Witness).
  • SegWit aims to reduce the size of all Bitcoin transactions, letting more transactions to come off at the same time.
  • However, SegWit was officially a soft fork and might have assisted in prompting hard forks after it was initially proposed.

Bitcoin Cash

  • Some community users and developers decided to introduce a hard fork in response to SegWit, as well as to evade the procedure-updates.
  • This, at the same time led to the creation of Bitcoin Cash.
  • Bitcoin Cash detached from the main blockchain in August 2017 – when Bitcoin transactions were excluded by Bitcoin Cash wallets.
  • Up till now, Bitcoin Cash is the most effective and successful hard fork of Bitcoin.
  • Bitcoin Cash is also the 4th largest cryptocurrency by market cap and allows blocks of 8 megabytes.

Bitcoin Gold

  • After the creation of Bitcoin Cash, Bitcoin Gold was created.
  • The creators of Bitcoin Gold intended to evoke the mining functionality with elementary GPU (Graphics Processing Units) since they experienced that mining became also particular – in terms of hardware necessities.
  • Post-mine is an exclusive feature of the Bitcoin Gold and a procedure through which the developers mined 100,000 coins.
  • In general, Bitcoin Gold follows the basic concepts of Bitcoin.
  • Also, it is different in terms of ‘proof-of-work algorithm.’

As Bitcoin has been forked quite a few times within few years, there is a possibility that Bitcoin would still continuously experience both soft forks and hard forks in the future.

A Hard Drive Worth $75 Million That Won’t Recover

Want create site? Find Free WordPress Themes and plugins.

James Howells, the IT laborer who unwittingly disposed of a hard drive containing what is currently valued at around $75 million worth of bitcoin, knows where the missing hard drive is, but he can’t try to recover it. That’s because the city in which the fortune is covered won’t enable him to delve into the landfill.

The missing hard drive is sitting somewhere under 200,000 tons of junk in a Newport, South Wales landfill.

Howells used an old PC to mine a sum of 7,500 bitcoins in 2009. Presently, he sold the parts to the Dell M1710 on eBay after his girlfriend complained about the mining’s clamor. He kept the hard drive in a cabinet, just in case the bitcoins increased in esteem. However, he overlooked the hard drive, and after four years, he disposed of it with the trash.

Howells has not been able to get consent from city chamber to dig into the landfill to recover the hard drive. Doing as such would require particular hardware that is typically used as a part of criminal examinations.

He was informed that a situation where even the police needed to go digging would require a group of 15, incorporating diggers with compulsory personal protection equipment. He couldn’t reserve such an operation, so he set up a wallet for donations:

City Council Denies Permission:

A Newport City Council representative said somebody has reached them in the past about recovering IT equipment containing bitcoins, but the chamber has shied away because of the expenses of uncovering the landfill and treating the trash, as per Wired. Such an exertion would cost millions and be environmentally destructive, with no assurance that a working drive would be recuperated. Around 50,000 tons of waste is added to the landfill every year.

A city chamber representative said the drive has likely experienced genuine galvanic corrosion from landfill leachates and gases. The landfill isn’t open to the public use.

Howells has the public address for his bitcoin, so he knows the bitcoins have not been moved. Since the information is encrypted, any individual who finds the hard drive would require Howells’ assistance to get to it.

How to Assess Basic Principles Of An Initial Coin Offering

Want create site? Find Free WordPress Themes and plugins.

A person who is not accustomed or used to the terminologies of crypto industry, it is difficult to conceive the idea of initial coin offering or why the tokens are generated and how to assess an initial Coin offering. For a cryptogeek it is quite simple, for him an ICO is a tool that is used to trade future crypto coins which are exchanged for cryptocurrencies having instant or liquid value. This definition may be simple for a person who deals in all sorts of cryptocurrencies and has undergone various ICOs but when talking about a layman who has no sound knowledge of crypto, it may get complicated.

How to assess an initial coin offering

For your ease of understanding we have devised a simple example from everyday life which will be quiet helpful for you if you want to understand the basic principle of initial coin offering.

Example From Everyday life

Imagine you want to start a business of your own, you have selected the appropriate location for it, and you’ve also planned the interior and exterior design with the sort of items you are going to sale.

 

But, There’s one most important thing remaining …..

 

Without a handsome amount you cannot initiate your business, You must rent or purchase the place you have chosen, stock it with the items you want to sale and also hire some staff to tackle it the way you have devised in your mind.

 

Let us assume that you are an innovative person and you don’t want to get a loan from any one, you just want to initiate your own sum. For that purpose you produce your own branded product with some specific name say for example “BIT”. But you only generate it in a limited quantity of 1,000 pieces. Let us call each piece a currency, and customer won’t be able to buy that currency until they acquire them using special tokens that you’ll release gradually over the specific period of time following your business launch date.

 

If demand for BIT is high enough and if you succeed in making your buyers believe that its demand will continue to grow, that will automatically push up the price of the tokens generated in the future. These tokens would obviously sell for large sums and as a result you’ll raise enough money to launch your business.

 

You can make it further simple to say that first you offered shares for a company which you have not yet launched but you had developed a significant trust so public bought that share for the sake of investment. That was an Initial Public Offering from your side.

How To Apply The Same Principle To ICO?

The principle elaborated in the above example, is also behind an ICO. The same way you offered the public initial shares of your company, an ICO gives public the right to buy a product which exists in a limited quantity. The company offering that product has an option to sell its rights for a higher price.

 

The beauty of the above process and the thing which differentiates it from the prior IPO example is that it is supported by blockchain technology. This technology guarantees the authenticity of the tokens offered. In short ICO is a whole new way for businesses to raise money. According to the latest ICO news update, it has already been used to generate approximately 2 billion dollars.

How is ICO Risky?

Well, we have full trust on the blockchain technology but we have no issue in admitting that it can too be risky as compared to the Initial Public Offering. Let us see how?

 

First of all the most satisfactory thing about the IPOs is that they are well regulated. Companies which make such offers are lawfully bound to reveal all sorts of information about themselves before they make it fully public. It allows investors to make fair-minded estimations about their value. The main thing is that people making these investments have full knowledge about the Pros and Cons.

 

On the other hand people who invest in an ICO have comparatively less knowledge of what they are investing in and what will be the nature of their return. But it can be easy for you if you follow the following principles devised by our crypto experts:

Factors You Must Examine

  • Is the admin panel team of that company experienced?
  • Does the product offered by the company have a good market? If the product isn’t a hot item, there’s is no use to invest in it.
  • You must have proper knowledge of the blockchain technology which is underpinning the sale. How many tokens have been distributed uptill now and what is their security level.
  • The legal and regulatory stuff surrounding the company is safe or not?
  • What are the terms and conditions outlined in the white paper and do they look fair?

 

We hope that after following these rules and regulations it will be easy for you to make a smart decision in terms of ICO investment, still we are waiting for your suggestions and criticism in the comments section below.
