This is the same mining industry that secures and verifies all the Bitcoin transactions. That, as most of us know, was not the vision of the original Bitcoin. Bitcoin, originally, had envisioned that anyone on the internet would have the opportunity to participate in Bitcoin mining.
They could easily do so with their own personal computers. Doing so would have also earned these individual users a bit of extra money. Well, because these individual users who have helped and supported the Bitcoin network with their machines. Soon enough some people discovered that they could carry out Bitcoin mining much more efficiently if they used ASICs. ASICs is short for custom-build application-specific integrated circuits.
Consequently, the Bitcoin mining industry became more and more specialized. That is also the reason why the leading Bitcoin mining companies in a completely new industry started to wield a disproportionate percentage of influence and power over the entire mainstream Bitcoin network. The market is now filled with different cryptocurrencies. Each claims its own benefits over the rest. As pointed out earlier, Bitcoin Gold wants to change that. And basically, dethrone the big mining companies that have taken over the mainstream Bitcoin network.
Well, Bitcoin Gold aims to get rid of these big mining companies via a new method. This new method would have Bitcoin Gold introducing alternative mining algorithms which would have more resistance to ASIC-based optimization. This is exactly what the average user did in the early days of the mainstream Bitcoin network as well.
To understand it, we have to remember the fact that the mainstream Bitcoin network is, at its core, a blockchain. This ledger records every Bitcoin transaction that has ever taken place. For doing so it earns a reward that amount of If we take Bitcoin for what it is worth today then that total of As you would expect, Bitcoin miners for to desperately compete with each other to avail the privilege of adding another Bitcoin block to the mainstream Bitcoin blockchain.
Basically, you have Bitcoiners miners talking a list of Bitcoin transactions and then adding a random string. Bitcoin miners add the nonce to the end of the blockchain. Then these miners compute an SHA bit hash function of a while particular Bitcoin block. A hash function is designed in such a way to produce a fundamentally random string of bits. These random strings of bits essentially represented the hashed data in a unique way. The miners win if the above-mentioned random bits begin with a very specific number of zeros.
A lot of the time, as you would imagine, this does not happen. Then these miners repeat the whole calculation process again. They continue to do so until they get to a winning block. And make some money. A given miner who manages to discover a winning Bitcoin block then goes ahead and announces the discovery to the rest of the mainstream Bitcoin network. Then everyone else on the mainstream Bitcoin network verifies that the discovery meets all the standard requirements of the mainstream bitcoin network rules.
After that, everyone adds that winning block to their own copies of the Bitcoin blockchain. But the point we want to make here is that this is the process that gives the mainstream Bitcoin network the ability to reach a consensus. So what happens if two Bitcoin miners announce two winning blocks at the same time? Will the original BTC respond do all the new up and comers who want to dethrone it? Well, the community simply settles it by running for another round of the Bitcoin mining race.
In other words, most users in the Bitcoin community had a bit of spare computing power lying around near their desks. And a lot of those users could devote that extra computing power to the Bitcoin network via mining. In the process of doing so, they also earned virtual currency.
Professional miners are users who have dedicated hardware for Bitcoin mining. As mentioned before, that began to change not long after. And after a little while, Bitcoin mining became the domain of professional miners. Mining slow became an activity for only those who had access to these chips. Only ASICs operations could handle mining with concentrate power and low electricity costs.
That is the main objective of new cryptocurrencies such as Bitcoin Gold. The strategy that we have discussed before is basically known only as a proof of work.
To have influence over the mainstream Bitcoin network one has to have the proportional computer power. In other words, the more work a user can finish, the more likely that user is to win an opportunity to add a Bitcoin block to the end of the Bitcoin blockchain.
Regulators have decided on a comprehensive ban on channels for the buying or selling of the virtual currency in China that goes beyond plans to shut commercial bitcoin exchanges.
Trading volumes on Localbitcoins subsequently spiked exponentially, news. Last week, Bitkan suspended its OTC cryptocurrency trading service.
A broader clampdown will likely include blocking mainland access to websites of foreign bitcoin exchanges such as Coinbase in the U. This concurs with a document which surfaced last week detailing how the Chinese government will try to block access to bitcoin exchanges and other important services that reside outside of the country. While the document is unverified, Sina claimed that it is authentic. According to the above document, all DNS and IP addresses of websites, apps, and APIs from foreign bitcoin exchanges will be analyzed, and access to each will then be blocked by the Great Firewall before September The document also indicated an attempt to disrupt the basic P2P network routing of Bitcoin itself inside the country, which could disrupt the flow of bitcoins across the border.
The government will monitor the network communication between domestic nodes and pools to prevent domestic nodes from syncing with nodes abroad. Earlier this month a Chinese man was imprisoned for doing so.
