Bitcoin Cash’s shocking announcement on Saturday that they’ll go in improve with a fork on August 1 caught a lot of people, which consists of myself, by using surprise. In this article, I’m going to provide an explanation for what Bitcoin Cash (BCC) is, how it influences you and how you have to prepare for August 1.
What is Bitcoin Cash?
Here is the project announcement on Bitcointalk.
-Here is the project website.
-From the project website’s FAQ:
What is Bitcoin Cash?
Bitcoin Cash is peer-to-peer electronic cash for the Internet. It is fully decentralized, with no central bank and requires no trusted third parties to operate.
The distinguished use of “peer-to-peer digital cash” is purposeful here. Bitcoin Cash is looking for to be a cryptocurrency that’s targeted on transaction capacity.
Why is this fork a surprise?
Many human beings (including myself) concept that this fork would only trigger if BIP148 had been capable to split the network. In other words, many human beings concept Bitcoin Cash (and its patron Bitcoin ABC) was once just a credible hazard to stop a contentious user-activated gentle fork (UASF). Bitmain clearly stated that the Segwit2x (aka New York Agreement) would be preferable:
So naturally, when BIP91 (first part of Segwit2x) locked-in and activated in advance of BIP148, which is scheduled for August 1, most assumed this would stop the so-called user-activated challenging fork (UAHF) from triggering.
But, it appears like Bitcoin Cash supporters had different ideas.
Why should I care?
You should care because Bitcoin Cash is a permanent fork of Bitcoin.
From the project website’s FAQ:
Is Bitcoin Cash different from ‘Bitcoin’?
Yes. Bitcoin Cash is the continuation of the Bitcoin project as peer-to-peer digital cash. It is a fork of the Bitcoin blockchain ledger, with upgraded consensus rules that allow it to grow and scale
This capability that if you personal Bitcoin (that is, you manipulate your very own private keys) prior to the fork on 2017 August 1 12:20 UTC, you will have the same quantity of Bitcoin and Bitcoin Cash after the fork.
Lest you suppose these BCC isn’t well worth anything, BCC futures are presently buying and selling at about $475 on ViaBTC.
What do I need to know?
First, you understand that many exchanges, inclusive of Coinbase, are truely now not prepared for this event.
From the project website’s FAQ:
If I own Bitcoin, do I automatically own Bitcoin Cash too?
Yes. Because Bitcoin Cash is a fork of the ledger, that means you own the same amount of Bitcoin Cash as you did Bitcoin at the time of the forking block. However, if your Bitcoins are stored by a third party such as an exchange, then you must inquire with them about your cash.
Note that last sentence. Exchanges or third-party bitcoin storage carriers can also or can also now not provide you your Bitcoin Cash. It’s probable that 1/3 party offerings will strive to do the proper thing, however there’s no way to understand if they can get everything set up in time to be in a position to provide you the Bitcoin Cash you’re entitled to.
Second, all difficult forks present two risks: replay and wipeout attacks. Wipeout is not a as much threat in view that this is a permanent fork (there are scenarios where one chain’s miners may also assault the other, but this isn’t in play yet). Replay safety is furnished as phase of the Bitcoin Cash release as explained in the FAQ:
How is transaction replay being handled between the new and the old blockchain?
Bitcoin Cash transactions use a new flag SIGHASH_FORKID, which is non standard to the legacy blockchain. This prevents Bitcoin Cash transactions from being replayed on the Bitcoin blockchain and vice versa.
Rest certain that as lengthy as you manipulate your very own non-public keys, you should be in a position to use these keys to create transactions on both chain safely.
I thought Bitcoin solved scaling! Why is this happening?
Good question. After the scaling drama of the past few years, we subsequently made growth when BIP91 locked in on Thursday. Though Segwit will increase transaction capacity, it’s not performed so in a way that every body is completely satisfied with.
BCC looks like an appeal to the segment of the Bitcoin customers that don’t like Segwit. Since Segwit is getting activated on Bitcoin, this fork gives many of these human beings a place to go.
From the project website’s FAQ:
Why was a fork necessary to create Bitcoin Cash?
The legacy Bitcoin code had a maximum limit of 1MB of data per block, or about 3 transactions per second. Although technically simple to raise this limit, the community could not reach a consensus, even after years of debate.
So what features does Bitcoin Cash have?
Bitcoin Cash affords three new features. First, it offers a tons larger block dimension of 8MB.
Second, it presents replay and wipeout protection. The transaction signature is slightly specific and the forking block has to be greater than 1MB.
Third, it offers a way to modify the proof-of-work problem faster than the everyday 2016 block issue adjustment interval found in Bitcoin.
From the project Bitcointalk:
Forking rule:
REQ-7 Difficulty adjustement in case of hashrate drop
In case the MTP of the tip of the chain is 12h or more after the MTP 6 block before the tip, the proof of work target is increased by a quarter, or 25%, which corresponds to a difficulty reduction of 20% .
RATIONALE: The hashrate supporting the chain is dependent on market price and hard to predict. In order to make sure the chain remains viable no matter what difficulty needs to adjust down in case of abrupt hashrate drop.”
In other words, the difficulty will adjust pretty quickly should there be a low hash rate.
What does this mean for Bitcoin?
This is the hardest aspect to answer. It may additionally suggest nothing, it may additionally imply a lot. Some apparent things that we’ll now want to think about are:
-Who will mine Bitcoin Cash?
-Who will have the larger hash rate? Both coins will use double-sha256 as the proof-of-work.
-What will the price ratio be?
-What will the volumes on both coins be like?
-How will hash rate react to price? How will price react to hash rate?
-How will this affect the 2x HF part of Segwit2x?
-What chain will coins that operate on top of Bitcoin like Omni and CounterParty choose?
Conclusion
Unfortunately, the Bitcoin Cash announcement brings more questions than answers. One factor is for certain: if you prefer to maximize your holdings, it’s in your first-rate activity to get your Bitcoin off third-party offerings and manipulate your very own non-public keys earlier than August 1st.
