This feature would be called Segregated Witness aka Segwit. So by removing the signature data from the transactions, it was killing two birds with one stone, the block space got emptier and the transactions became malleable free. There was one more thing that needed to be worked on, however. Segwit activation was possible only via a hard fork, which is what everyone wanted to avoid.

The developers wanted to look at soft fork alternatives. That was when Luke Dashjr hit gold. To utilize segwit as a soft fork the developers had to come up with 2 ingenious innovations. They are as follows:. Doing this not only ensured that Segwit implementation was a soft fork, but it also increase the block size limit as well.

This was a major breakthrough but not everyone was happy with this solution. In fact, this directly led to the creation of Bitcoin Cash, which we will talk about later. After crashing down from its December peak, Bitcoin has recently seen three consecutive bullish months following six straight bearish months. Over the last few days, the number of daily transactions have ranged between , and , However, on 2nd May, the number of daily transactions exceeded , In our dataset, the average transaction fees were Bitcoin XT was the first notable fork of the bitcoin protocol and faced widespread media coverage.

What will be the impact

Mike Hearn, launched the software in late to include some of the changes that he was proposing to Bitcoin Core. Even though the Bitcoin XT experiment failed, some community members still felt that the blocksize increase was the way to go forward. Thus Bitcoin Classic came about, which aimed to increase the blocksize from 1mb to 2mb as opposed to 8mb. Like XT, Classic saw initial interest with about nodes using the software, however, the number fell dramatically over time. Bitcoin Unlimited grants their users the power to choose whatever blocksize they want to go with.

The limit that achieves the majority consensus in the network would be the new blocksize limit.

Bitcoin Unlimited found support from Roger Ver, Antpool, bitcoin. As you can see, there are some very noticeable dips in the graph about. Those dips happened because of certain issues that have plagued Bitcoin Unlimited. What we are going to see now are the hardforks of the Bitcoin cryptocurrency itself.

Because of this, people and organizations that can afford faster and more powerful ASICs usually have better chance of mining than the others. This is why Bitcoin Gold came about which uses the memory hard equihash as proof-of-work algorithm instead of the sha They mined , coins right after the fork via rapidly mining blocks at These coins were used for two purposes:. As a result, they were forced to hard fork to decentralize the mining hash power. In the three latest months, they gained the most in April.

The average hashrate of BTG in our data set is 3. The graph above shows the entire amount of transaction fees sent per day in our data set in USD. In our dataset, the daily trade amount exceeded 1, BTG just once and that was on May 3rd. Overall, it exceeded BTG in four out of the six days. The average amount of Bitcoin Gold sent in our dataset is The Bitcoin Private hardfork took place on 28th February at block Its use in modern blockchain technology is immense. They were working on problems related to interactive proof systems, where a Prover exchanges messages with a Verifier more on provers and verifiers later to convince them that they have a knowledge of a certain proof without declaring what that knowledge is.

The hour volume of BTCP is wildly fluctuating. The average of hashrate in our data set is 1. It is fully decentralized, with no central bank and requires no trusted third parties to operate.

One of the best features of Bitcoin Cash is how it circumnavigates one of the biggest problems that any cryptocurrency can face post-forking, the replay attack. A replay attack is data transmission that is maliciously repeated or delayed. In the context of a blockchain, it is taking a transaction that happens in one blockchain and maliciously repeating it in another blockchain. So, how does bitcoin cash prevent replay attacks? February, March, and April have been progressively more bullish. The average hashrate plummeted around 29th and 30th April and then picked right up.

The three latest days in our dataset saw the avg.

Total transaction volume exceeded 3 million in four out of the six days in our data set. Here we have the amount of BCH that was traded per day. Apart from April 28th, five out of the six days on our data set had more than 40, BCH traded, reaching a peak of 57, on May 3rd. In our data set, an average of 46, One thing that you need to remember here, script is a purposefully simple and non-versatile language.

It is not a highly-functional, Turing-Complete language like solidity which is used to create smart contracts. Those opcodes being:. They wanted a Bitcoin Cash which was close to the original blueprint as possible. Hence, Bitcoin SV was born.

How to get ready for BCH hard fork coming in November

Bitcoin SV is not going to use these new opcodes. In April , Craig Wright sent out multiple lawsuits to people who have trolled him for claiming to be Satoshi Nakamoto. This move resulted in Wright receiving widespread criticism which eventually led to exchanges like Binance and Kraken to delist them. The graph calculates the total transaction fees in dollars per day.

The idea of this guide was not to demonize any particular project. We just wanted to increase awareness and to reduce the confusion.

BitcoinZeroX: This Bitcoin fork date is scheduled for September , however it is yet to be confirmed. The fork will be a combination of Bitcoin and Hexxcoin. As you probably know, Bitcoin is the first and original cryptocurrency. When it was launched in , the main purpose of Bitcoin was to create a global payment system that could be used by anyone in the world, without needing transactions to be confirmed by a third party.

However, even though Bitcoin is coming up to its tenth year of trading, transaction times are still very slow at just 10 minutes. Furthermore, the network can only handle around 7 transactions per second and transaction fees seem to be getting higher and higher.
