Bitcoin mining is done through a hardware called bitcoin miner. The hardware can be divided into three main categories, each more expensive and powerful than other.

Here, we have explained each category and described how to set up a Bitcoin miner.

While setting up a bitcoin miner, the first thing you will need to do is to choose the hardware, and there are two main things to particularly think about: hash rate and energy consumption.

Hash Rate:

Hash rate is the number of calculations per second performed by the miner to crack the mathematical problems in Bitcoin mining setup.

They are measured in Megahashes (MH/sec), Gigahashes(GH/sec), and Terahashes (TH/sec) per second.

The higher your hash rate, the easier it is to solve a transaction block.

Energy Consumption:

Mining equipment is unfathomably powerful and chews up a gigantic amount of electricity, which, ultimately results in higher costs.

While searching for the equipment, make sure its energy consumption is in watts. You need to ensure that you don’t wind up spending the majority of your cash on electricity bills to mine coins that won’t be worth what you paid.

In case you need to work out how many hashes you are getting for each watt of electricity, divide the hash tally by the number of watts consumed.

For instance, a device with 500 GH/sec that takes 400 watts of electricity, then you’re getting 1.25 GH/sec per watt.

You can also use several online electricity price calculators to figure out the value in traditional currency.

Types of Mining Hardware:

Bitcoin Mining pc comes in three major categories, GPU/CPU, FPGA, and ASIC.

GPU/CPU:

The least powerful consuming machine to mine Bitcoin is your very own regular PC. Theoretically, you can use a regular PC for mining purpose, but its processing is so slow, there is no point in using it.

To enhance the processing power i.e. hash rate, add a graphics hardware to your PC. The hardware features graphical processing units (GPUs).

GPUs are intended for overwhelming mathematical lifting which is utilized as a part of computing all the complex polygons required in the top of the line computer games.

This ability makes them great at the SHA hashing mathematics which is essential for solving transaction blocks.

FPGA Mining:

FPGA (Field Programmable Gate Array) empowers a mining equipment producer to purchase the chips in volume, and afterward customize them for Bitcoin mining before placing them into their own particular gear.

Due to the fact that they are customized for mining, they offer enhanced performance as compared to CPUs and GPUs.

ASIC Bitcoin Miners:

Application Specific Integrated Circuit (ASIC) is where all the action takes place. ASICs are particularly manufactured perform only one task: mine bitcoins at mind-squashing speeds, with lower power consumption.

Because ASICs are designed specifically for high-speed mining, they are expensive and time-consuming to produce. However, the speeds are unbelievably fast.

The current units can reach the hash rates between 5-500 Gigahashes/sec, and the future units are promised to go even higher.

All Set? Join a Pool:

When you have Bitcoin mining set up, your next stride is to join a mining pool. Bitcoin miners put their assets and share their hashing power in these pools. Once the mining completes, the individuals from a pool get a reward which is then split among all the members, based on the number of hashes shared by an individual.

IBM’s Affordable Blockchain ‘Starter Plan’

Want create site? Find Free WordPress Themes and plugins.

The IBM Blockchain is a hot topic these days. No doubt, blockchain technology is an ingenious invention which allows digital information to be distributed without allowing to it to be copied or modified. Though it was invented by Satoshi Nakamoto in its initial form but uptill now it has evolved itself into a digital giant. That’s why every person somehow related to the internet technology has asked the question:

What is blockchain?

In short, blockchain is the backbone of a new kind of internet technology. In its original form, blockchain was being devised specifically for the cryptocurrency, Bitcoin. It is also known as the distributed ledger technology as it maintains a flawless record of digital transactions. Due to its credibility, blockchain has also been used by the tech community in various other ways. Furthermore, IBM Blockchain technology is a much more refined form of this digital platform.

As we all know, IBM is on the top of the list as it has been working with Blockchain technology since 2015. The credit of bringing blockchain to mainstream also goes to IBM. It was in 2016, when IBM started to use Blockchain technology in their own company.

And now IBM has presented the concept of an affordable Blockchain Starter Plan especially designed for small scale businesses.

IBM’s business blockchain network

At an initial stage a beta version of Blockchain Starter Plan will be launched in order to facilitate the use of Blockchain in all sorts of businesses. For that purpose, in 2016 IBM launched a test Blockchain program in partnership with Walmart.

This starter plan will be free for the duration of its beta version. After completion of the beta version duration a 30-day free trial will be offered once the plan becomes applicable in its full form.

How will all this work?

To be precise, business blockchain network uses the so called distributed ledger technology in order to make sure a secure transfer of business assets inside that network. The beauty of this process is that these assets can be both in physical or digital form. Members of this network would use a concord mechanism instead of depending upon a bank or other such institute for the validation of their transactions. It will automatically not only improve the processing speed of transactions but will also become the first step towards transparency across the business network.

According to Marie Wieck, the general manager of IBM Blockchain, the company currently has over 250 active blockchain networks. She further stated that this new plan will suit pilot projects and will be perfect for those who want to build solutions on the IBM blockchain platform.

Sometimes you have to face different issues with your funds. They may be snatched or hacked by someone. Whereas, bitcoin is a digital currency and addresses may be hacked by someone. To prevent from hacker, bitcoin must be kept behind multiple layers of security. In this article, we will discuss the ideas, how you can prevent your accounts as well as your addresses.

The most important feature of the bitcoin is transactions aren’t reversible. This means that once you do transactions either receive or send coins, they don’t have revers back feature. But, if your bitcoin account gets hacked then also you are not able to get back them.

Make sure first while you are dealing with someone via bitcoin technology. That person should be reliable and well-reputed. These precautions are necessary, but this is incomplete security.

To secure your accounts some basic personal checks, which may reduce the chances of your account being hacked or compromised. They are;

  4. Enabling two-factor authentication

The Main Issue:

Someone breaks into an unlocked house and take precious diamond jewelry away. This is not jeweler’s fault. You were not able to keep your things secure from a robber. Same with the email accounts. People says that their accounts got hacked. The reason is they don’t completely put security to their accounts.

If a hacker has access to your email account, he will see the history of websites you log in. In addition, will visit the sites one by one and ask to reset the new password. Once the password gets restart, you will easily cut off from your account.

Secure Your Email Accounts:

Following are some terms by which you can secure your account.

  • use the strong and unique password
  • keep eye on login activity
  • review and remove email auto forwarder
  • the review linked accounts
  • 2-factor authentication

Use Strong And Unique Password:

Now, its technology era and you have to follow its rules and regulations. When you make an account on social media you have to use unique and strong password consisting of letters, words or capitals. In addition, especially in a case of bitcoin. You have to make sure that your password is strong, tricky and unique.

Keep Eye On Login Activity:

well-reputed email provider websites allow you to see which locations and devices recently accessed your email account. If your email account is open on both laptop and mobile, sites will show you double login sessions. And, you don’t recognize your login session, immediately sign out of all other sessions.

Review And Remove Email Auto Forwarder:

Most of the email sites provide a feature where email can be forward to different addresses automatically. If you monthly received the invoice from telephone company then your spouse or housemate will receive the copy of the same email. Which is more secure for your email accounts.

Here, the issue is, if the hacker got access to your accounts in past. Possibly they have auto-forward setup. Accordingly, the one for sensitive emails to be forwarded to them. These saved emails can be used against you.

Review Linked Accounts:

Review links accounts may be used for good and bad both purposes. We humans like new changes in our routine life. The problem is when we don’t want to log-in and after switching to new one, emails still send to the old addresses.

In that sense, you simply link to two accounts. And, you also have the accesses to both accounts, you can log into the new one, link the old one and all emails sent to the old account will still arrive in your new account. You can send email from a new account by using the other addresses. while you are doing small business it is useful for you. Where you can receive, and send the email to the same inbox. But, the problem is still the same. If your account gets hacked and hacker receives and send the emails same as you. In that scenario, you don’t have another option. So, keep your accounts secure by adopting different ways of security.

2-Factor Authentication:

Two factors authentication needs two things to get access to your email account.

  • your password
  • your mobile phone

If two-factor authentications are enabled, no one can get access to your email account.

Secure Your Technology Related Social Media Accounts:

People are friendly with the social media they do the same with email accounts. They won’t need a new password or new email account.

 

 

For all the online accounts, use unique and strong password

your password should be strong and unique. The reason behind is,

Why Should Password Be Strong And Unique?

we already discuss that password of your accounts should be strong. It is simple, that your login different accounts with same and simple password. You are leaving your account open to hacking.

Especially, when you are treating with bitcoin wallet addresses. you need more security for your funds. Hundreds of time we log in with hundreds of the sites. Which may have an option of encrypting. So, it’s totally up to you to choose a suitable and reliable site for your transactions.

It very simple for the hackers to hack bitcoin wallet. So, use password management tool for a strong and unique password. It will help you surely.

Enabling Two-Factor Authentication:

One of the best and free ways to secure your accounts is two-factor authentication with the time period of two minutes only. 2F-authentication create an extra layer to any account by requiring two things. Are, • something you know which is your password. And,

  • something you have is your device

Now, many sites support two-factor authentications including google, Luno, and Facebook etc. It is possible that you already receive a message with the one-time pin for certain transactions from your bank or credit card provider. These are the type of 2F authentication.

How To Enable 2FA?

Bitcoin Goes High When Miners Take a Step to Solve the Scaling Problem of Digital Currency

Want create site? Find Free WordPress Themes and plugins.

Bitcoin miners are intending to support a new upgrade for the Blockchain of Bitcoin which may solve the scaling problem of digital currency. Most of the Bitcoin miners including Bitclub, AntPool, BTC.com, and BitClub have shown their interest to support the Bitcoin improvement proposal (BIP) 91, through adding a piece of code to every single new block of bitcoins they generated. This block needs 80% support to be “locked in” permanently to the blockchain. This will cause a relief as it stops the blockchain splitting into separate two chains, which would create two different coins effectively. Already 66 % of the last 144 blocks provided signal support for it.

According to Coindesk data, Bitcoin has recovered from a tough 8-weeks low of $1863 on Sunday to about $2329 today.

What is the Problem with Bitcoin?

 

Bitcoin has faced a scaling problem for some time, where the number of the transactions occur on the blockchain at one time are limited to 1MB every 10 minutes. This generates a backlog of the transaction which should process and slow things down.

The Bitcoin community has been looking for the best way to solve this scaling problem. Segregated Witness(SegWit) system is one of the solutions which would increase the transaction speed. But SegWit required about 95% support from the miners. Bitcoin fell about 12% on Sunday because of these concerns. However, Bitcoin miners have to respond to this problem.

What is the Solution of Scaling Problem?

Many members of the Bitcoin community have united on a solution known as BIP148. This may include a “User-activated Soft Fork”, where users of Bitcoin will force the blockchain to split by refusing any block of Bitcoin which didn’t indicate support for SegWit. BIP 148 was coming in action on 1st of August and if a large number of developers didn’t commit on the proposal, the blockchain can split.

Charles Hayter, founder and chief executive of CryptoCompare has explained, However, a large group of miners will continue to mine with Non-SegWit blocks in case of the BIP148. In such case two bitcoins would occur, one in which SegWit is active, and other in which SegWit is not active. This may have terrible results for one of the chains or even both. This could be one of the major factors behind the volatile support for BIP91.

Will Bitcoin Avoid a Fork?

To avoid Fork, miners are giving support behind BIP91, that would present SegWit2X to the blockchain. BIP91 requires only 80% support, rather than 95% and to be ‘locked in’ they would introduce the SegWit system.

The managing editor of The Black Swan Portfolio, Bram de Haas, told CNBC via an email on Tuesday, “BIP91 has a minor edge of adoption which made its implementation less risky and more realistic. Adopting the BIP91 will also decrease the possibility of a fork which many people like”.

Bitcoin will surely avoid a fork now but it’s not much terrible if it does not. Haas expected now the Bitcoin prices to rebound faster and faster.

Robinhood Launches Free Cryptocurrency Trading App in Colorado

Want create site? Find Free WordPress Themes and plugins.

Zero-commission startup exchange, Robinhood has announced its expansion in Colorado through social media giant, Twitter. According to Robinhood, the trading platform is going to provide a commission-free trading for top-cryptocurrencies in the western state, i.e. Bitcoin and Ethereum.

Colorado is best known for its blockchain-friendly legislation and ‘rocky mountain peaks’ has joined with few states, including;

  • California
  • Massachusetts
  • Missouri
  • Montana

Response from Twitter Followers

After this announcement on Twitter, a flurry of responses started out, as many requested the trading platform to add Litecoin and plead to expand into other states as well, like; Florida and Texas. According to Robinhood, you can expand the list by asking your friends to join the exchange as well. However, some twitter followers in the states say – where Robinhood cryptocurrency has rolled out, that they are stuck on a waiting list.

Zero-fee Exchange

Zero-fee exchange gains depend on the footholds in the US. If we talk about New York, the Attorney General of New York, Eric Schneiderman is in a bid for better transparency and has contracted with over dozen crypto exchanges with information requests. The expansion was quite enough to send the leading cryptocurrencies’ prices decline a little bit, however, they rallied later.

Gemini, which is a digital assets exchange and is run by the Winklevoss twins, is also ready to comply. However, others find the request quite insolent. Winklevoss twins (Cameron and Tyler Winklevoss) are leading a self-regulatory group as well for better practices in the crypto industry.

 

Robinhood didn’t specify whether it is going to support altcoins beyond Bitcoin and Ethereum but it does propose a market data for numerous altcoins. As the exchange is quite famous amid millennials, it is estimated to have the worth of almost $5.6 billion instantly from its latest. Although Robinhood is introducing a zero-fee crypto trading, it provides a premium account under the name Robinhood Gold as well.
