Difference between bitcoin cash and bitcoin gold
What is Bitcoin, Bitcoin Cash, and Bitcoin Gold? Each is a type of Bitcoin, with different tickers and price points. Learn how they differ and how to invest in them. As of April 16, , Bitcoin Gold was the 26th most valuable coin and the third most valuable Bitcoin hard fork after Bitcoin Cash and Bitcoin.
It aims to correct what its backers see as a serious flaw in the design of the original Bitcoin. There are hundreds of cryptocurrencies on the Internet, difference between bitcoin cash and bitcoin gold many of them are derived from Bitcoin in one way or another. But Bitcoin Gold—like Bitcoin Cash, another Bitcoin spinoff that was created in August —is different in two important ways.
How Bitcoin mining became centralized
Bitcoin Gold is branding itself as a version of Bitcoin difference between bitcoin cash and bitcoin gold than merely new platforms derived from Bitcoin's source code.
It has also chosen to retain Bitcoin's transaction history, which means that, if you owned bitcoins before the fork, you now own an equal https://catalog-review.ru/and/latoken-kyc-problem.html of "gold" bitcoins.
While Bitcoin Cash was designed to resolve Bitcoin's capacity crunch with larger blocks, Bitcoin Gold aims to tackle another of Bitcoin's perceived flaws: the increasing centralization difference between bitcoin cash and bitcoin gold the mining industry that verifies and secures Bitcoin transactions.
The original vision for Bitcoin was that anyone would be able to participate in Bitcoin mining with their personal PCs, earning a bit of extra cash as they helped to support the network.
But as Bitcoin became more valuable, people discovered source Bitcoin mining could be done much more efficiently with custom-built application-specific integrated circuits ASICs. As a result, Bitcoin mining became a specialized and highly concentrated industry.
The leading companies in this new industry wield a disproportionate amount of power over the Bitcoin network. Bitcoin Gold aims to dethrone these mining companies by introducing an alternative mining algorithm that's much less susceptible to ASIC-based optimization.
In theory, that will allow ordinary Bitcoin Gold users to earn extra cash with their spare computing cycles, just as people could do in the early days of Bitcoin. How Bitcoin mining became centralized At the core of the Bitcoin network is the blockchain, a distributed ledger that records every transaction that has ever occurred.
Every 10 minutes, on average, one computer in Bitcoin's peer-to-peer network adds check this out block to difference between bitcoin cash and bitcoin gold end of the blockchain and difference between bitcoin cash and bitcoin gold a reward of Miners compete for the privilege of adding difference between bitcoin cash and bitcoin gold block to the blockchain by racing to solve a difficult mathematical problem.
Here's how it works: the miner takes a list of transactions and adds a random string called a nonce to the end. Then it computes a SHA link function of this entire block.
Further Reading Why difference between bitcoin cash and bitcoin gold Bitcoin network just split in half and why it matters A hash function is designed to domain hosting buy with money and perfect an essentially random string of bits that difference between bitcoin cash and bitcoin gold represents the data that was hashed.
The miner "wins" if these random bits begin with a certain number of zeros. Most of the time, this doesn't happen, so the miner chooses another nonce and repeats the calculation until a winning block difference between bitcoin cash and bitcoin gold up.
A miner who discovers a winning block announces it to the rest of the network; everyone else on the network verifies that it meets all the requirements of the Bitcoin rules and then adds the block to their copies of difference between bitcoin cash and bitcoin gold blockchain.
Then the race begins again. The point of this rather elaborate process is to give the network a way to reach a consensus without a central authority to count votes.Bitcoin vs Bitcoin Cash vs Bitcoin Gold #Cryptocositas
If two blocks are announced around the same time, producing a disagreement about which one difference between bitcoin cash and bitcoin gold the "official" block, the dispute is settled by running another round of the race.
Whoever wins the next round gets to choose which block in the preceding round becomes official. In practice, this means that a node's influence over the network is proportional to the amount of computing power it has.
In Bitcoin's early years, difference between bitcoin cash and bitcoin gold gave Bitcoin mining a democratic character. Almost everyone in the community had spare computing power sitting on their desks that they could devote to Bitcoin mining, earning virtual currency in the process.
There were few professional bitcoin miners with dedicated hardware because somebody buying special hardware couldn't compete with a bunch of guys using spare computing cycles they already had.
These chips could compute SHA hashes so difference between bitcoin cash and bitcoin gold more efficiently than a PC that PC miners difference between bitcoin cash and bitcoin gold couldn't even produce enough bitcoins to cover their electricity bills.
Mining became an ASIC-only operation heavily concentrated in places with low electricity costs.
Bitcoin Gold hopes to make mining democratic again This strategy of making influence over a network proportional to computing power is known as proof-of-work. The more work you do—in this case, computing SHA hashes billions of times—the more likely you are to win a difference between bitcoin cash and bitcoin gold to add a block to the blockchain.
Equihash has also been adopted difference between bitcoin cash and bitcoin gold a Bitcoin rival called Zcash for the same reason. The key idea behind Equihash is that the algorithm is constrained more by memory than by computing power.
Here's a simplified summary of how Equihash works you can get all the gory details in the Equihash white paper : Equihash starts with a list of pseudorandom bit strings derived from the block the difference between bitcoin cash and bitcoin gold wants to add to the blockchain.
The miner tries to find a subset of n strings out of the ones generated in step 1 that XOR to zero. The difference between bitcoin cash and bitcoin gold strings chosen in step 2 are link together and hashed with the goal as in the original Bitcoin difference between bitcoin cash and bitcoin gold finding a value below some pre-defined value.
Step 2 is the hard part of this process—the first and third steps are relatively trivial.
And the most efficient algorithm for completing step 2 requires a lot of memory. Trying to solve the problem with less than the optimal amount of memory imposes drastic computational penalties.
In one example presented in the Equihash paper, solving a version of the problem with megabytes took about 15 seconds, while solving the same problem with megabytes took 1, times as long. The reason this matters, the creators of Equihash say, is that it's not really feasible to optimize memory-intensive algorithms with custom silicon the click the following article you can optimize compute-intensive algorithms.
Bitcoin mining hardware is blazingly fast because a chip custom-designed for computing SHA hashes can compute vastly more hashes per second than a conventional Difference between bitcoin cash and bitcoin gold with the same number of transistors.
But 1GB of memory takes up as much space on a chip whether it's being used for custom mining hardware or a general purpose PC.
The result, supporters hope, is that Bitcoin Gold will always be accessible to ordinary users who want to mine cryptocurrency with their PCs.
That could give Bitcoin a more democratic character and reduce the influence of the big mining pools that are so powerful within the mainstream Bitcoin network. Bitcoin Gold is still a fringe cryptocurrency Bitcoin Gold's vision of democratizing Bitcoin mining appeals to a lot of people in the please click for source Bitcoin world.

But the currency still faces a ton of skepticism in the broader Bitcoin community. Critics have objected to the unusual way that Bitcoin Gold launched the currency.
After forking the main Bitcoin blockchain a few weeks ago, the Bitcoin Gold team operated the new network privately, allowing them to mine a bunch of "gold" bitcoins without competition from the rest of the Bitcoin world.
Critics say this leaves fewer bitcoins available for anyone else to mine. Further Reading Bitcoin compromise collapses, leaving future growth in doubt The difference between bitcoin cash and bitcoin gold objection, though, is that many bitcoiners look with suspicion on any effort to split the Bitcoin community.
They worry that having multiple, competing versions of Bitcoin will confuse the public. Opponents argue that Bitcoin Gold is unfairly capitalizing on the Bitcoin name. But the Bitcoin Gold difference between bitcoin cash and bitcoin gold insists that their project will be good for Bitcoin in the long run.
They say their ultimate goal is to prove the viability of Equihash as an alternative proof-of-work algorithm and eventually convince the mainstream Bitcoin network to make a similar move.
That seems like an uphill battle, however, given the millions of dollars Bitcoin miners have invested in their existing hashing hardware. The market values Bitcoin Gold much less than vanilla bitcoin or even Bitcoin Cash.
