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? This sighash algorithm is only used when the sighash flag has bit 6 set. These transactions would be invalid on the non-UAHF chain as the different sighashing algorithm will result in invalid transactions.
Any transaction which contains this string will be considered invalid by bitcoin cash nodes until the ,th block. How does Bitcoin Cash attract miners? Any cryptocurrency depends heavily on its miners to run smoothly. Lately, bitcoin cash has attracted a lot of miners which has significantly improved its hash rate. Here is how they did that. Bitcoin cash has a set rule as to when it decreases its difficulty.
It is the median of the last 11 blocks that have been mined in a blockchain. Basically, line up the last 11 blocks one after another and the time at which the middle block is mined is the median time past of the set. The MTP helps us determine the time at which future blocks can be mined as well. This gives the miners some power to adjust difficulty, eg.
The miners may have simply been doing this to make the blocks easier to mine. Another interesting thing to note is how and when the difficulty rate can adjust in a cryptocurrency. This is a graph which tracks the difficulty rate of BCH: The difficulty rate adjusts according to the amount of miners in the system.
If there are less miners, then the difficulty rate goes down because the overall hashing power of the system goes down. When bitcoin cash first started it was struggling a bit to get miners, as a result its difficulty dropped down drastically. This in turn attracted a lot of miners who found the opportunity to be very lucrative.
This caused an exodus of miners from BTC so much so that the hashing power of BTC halved, decreasing the transaction time and increasing the fees. Reports on social media stated that BTC transaction were taking hours and even days to complete. As of right now, there is a war taking place inside the Bitcoin Cash community.
Both these chains are utilizing there hash power to mine the longest chain. Whoever has the longest and more efficient chain, becomes the dominant Bitcoin Cash chain. So, this brings us to the obvious question. Why is the hash war happening? Well, there are two reasons: Block size surprise surprise!
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. They wanted a Bitcoin Cash which was close to the original blueprint as possible.
Hence, Bitcoin SV was born. Bitcoin SV is not going to use these new opcodes. The Ugly Side of The Hash War We will try to keep a very neutral stance here, but we need to report on just how ugly this war has become. There has been blatant name calling and negativity from both the the sides. In fact, some of the arguments have been no different than over-the-top pro-wrestling style rants. You can read it here. After that, it looks like Bitcoin ABC has suffered a big downturn in its hashrate while Bitcoin SV seems to have gotten the slight upper hand.
Bitcoin ABC has nodes right now. The number of nodes has decreased after seeing a peak on 16th August Bitcoin SV has a total of nodes. The total number of nodes increased dramatically since 15th November , i. After reaching its peak, the number of nodes has been pretty consistent.
According to coin. What is the future of Bitcoin Cash? We have no idea how bitcoin cash is going to turn out in the future nor do we know the long term repercussions that it will have on BTC. What we do know is that this is the first time that anyone has successfully hard forked from BTC whilst keeping the records of the existing transactions.
What we have here is a very interesting experiment which will teach us a lot of lessons moving forward. At the same time, the 8 mb block size is definitely a very alluring aspect and it remains to be seen how this affects the miners in the long run. However, the Hash War has opened up a very intriguing situation. With the sheer number of Bitcoin forks out there, it may dilute the value of Bitcoin even more.
The current market crash has been largely attributed to this war. The sad part is that the hash war has become really ugly.

The host of CNBC 's Mad Money , Jim Cramer , played himself in a courtroom scene where he testifies that he doesn't consider bitcoin a true currency, saying, "There's no central bank to regulate it; it's digital and functions completely peer to peer". For six hours two bitcoin networks operated at the same time, each with its own version of the transaction history.
The core developers called for a temporary halt to transactions, sparking a sharp sell-off. Gox and the Europe-based Bitstamp to become the largest bitcoin trading exchange by trade volume.
