So, what’s a decentralized system? In simple words, we can say that a decentralized system works with no servers and each member is permissible to execute transactions. But in the case of the blockchain, each member must have to do some system-tasks as well, such as; storing transactional data.

cryptocurrency Security

Fork: Even a group of members can run an alternate-version of reality, which is called “fork.” The fork works by the similar regulations as the original decentralized system – though it might have a diverse state.

Let’s enlighten you about the hierarchical nature of cryptocurrency security!

First Layer – Tokens and Crypto Coins

  • One of the first and foremost thing in the crypto world is your cryptocurrency security.
  • Whenever you choose a cryptocurrency, you take all the perils and risks related to the protocol.
  • If someone can recognize and utilize protocol flaws, they can compromise the whole network, even including you; it won’t be much important which exchange/wallet you are using.

In the first layer, you can find two different types of currencies which include, the coins (Bitcoin, Ethereum, Bitcoin Cash etc.) and all ICO-issued tokens such as; MOBI or EOS.

What is the Difference?

Well, the difference is in the technical features. Each coin is either an independent network protocol or just a copy of some of it. When you research a crypto protocol from a security stance, make sure to find out if it can be centralized.

Let’s take an example!

In the case of Bitcoin, it’s now centralized around four major mining pools which also means that if all of them collaborate, they can possibly compromise the whole network.

Another advice! Whenever you look for proof-of-stake crypto, make sure to have a look at the genesis. This is also quite imperative, as whoever keeps the preliminary and initial stake can vote for transitions, as well as the network will be also trusting those who have higher stakes. If we take an example of NEO, a PoS network of China, which is same as Ethereum, was distributed 50/50 amid its ICO sales and developer community – unlike Ethereum distribution. Also, the NEO token distribution makes sure that no major stakeholder from the exchange platform or the developing side has enough stake to compromise the whole network.

Tokens

  • Now if we talk about tokens, all of them are based on a smart-contract aspect of few of the coins, which means their reliability and security is first based on the parent cryptocurrency – only subsequently on the smart contract’s code that issued it.
  • Mostly, all ICO coins (tokens) are based on Ethereum and just some of them are issued by smart contracts.
  • Also, it is imperative to point out that Ethereum got hacked a few years ago due to the DAO protocol hack – later hard forked and rolled back to the state. This also shows that the founders of Ethereum probably have a time machine as it looks like they have the ability to go back in time – yet again if it’s required.

Second Layer – Exchanges

One thing that everyone must understand about the exchanges is that they are written in custom-code with infrastructure security and has got nothing to do with blockchain. If we talk about an exchange, it is just a standard centralized web service arrayed in a data centre. That’s why whenever we talk about the exchanges, we always mention reliability and trust.

Almost every month we hear news about the data breaches and security events that occur because of exchanges.

Examples

Here are some latest examples!

  1. Back in December 2017, $63 million in cryptocurrency was stolen from NiceHash by hackers.
  2. At the beginning of this year, January 2018, more than $500 million in cryptocurrency was stolen from Coincheck by hackers.
  3. In February 2018, almost $195 million in cryptocurrency was stolen from BitGrail by hackers.

The hype around cryptocurrencies is due to the number of data breaches. Many exchanges have recently started their business – without investing in proper security measures. Simultaneously, if someone steals tokens/crypto coins from an exchange successfully, it’s nearly impossible to do anything about recovering it.

Third Layer – Wallets

Well, the third layer is linked to your personal security in the crypto world and you must’ve heard a lot about it before.

When you select a wallet for cryptocurrencies, you’ll have two options:

  1. Hot Wallet
  2. Cold Wallet

Hot wallet Vs Cold Wallet

  • The hot wallet is just like an account in exchange or in simple words, it is a website-based wallet.
  • In the case of a hot wallet, your tokens/coins are under the control of your wallet provider.

Whereas, a cold wallet can be a hardware, software or just a paper.

Looking for Bitcoin Information? Here Is Everything You Need to Know

Want create site? Find Free WordPress Themes and plugins.

Bitcoin Information

Bitcoin is a digital currency that only exists electronically. To be more precise, it’s a cryptocurrency that is based on code and encryption keys. The currency first came into circulation in 2009 and was created by an anonymous programmer called Satoshi Nakamoto.

The currency is relatively new and not many people have any idea about how Bitcoin works. The goal of this post is to give newbies clearer understanding of what bitcoin is, how it works and how it can be used to buy/sell services and goods.

What Are Bitcoins?

People often confuse the terms Bitcoin (capitalized) and bitcoin (not capitalized) with each other, not realizing that these two are completely different entities.

Bitcoin latest news refers to the Bitcoin Network while bitcoin information refers to the currency itself (i.e. 1 bitcoin, 2 bitcoins).

What Makes Bitcoin So Special?

There are several factors that make Bitcoin special and give it an edge over traditional currency. The list is unending. However, I’m going to write some advantages of Bitcoin to give you a clear idea as to what makes Bitcoin so special.

  • Bitcoin is a peer to peer currency and is autonomous to third party influence.
  • Bitcoin transactions are stored in a public ledger called blockchain. The recorded information is transparent and offers open access to its users, making transactions more transparent.
  • Since the Bitcoin transactions don’t go through a clearing house (Government, MasterCard, Visa Card, etc.) the fees involved are extremely low.
  • The currency is stored in a Bitcoin wallet which is equivalent to bank accounts for traditional currency.
  • The security level of Bitcoin is extremely high. The currency is secured with encryption keys and only the owner of the coins can know about it; which makes stealing coins nearly impossible.
  • Bitcoins are finite and their value depends on the volume of usage. The more people use this currency, the higher it goes in value.

These are some of the key features that make bitcoin special.

Are Bitcoins Decentralized?

Yes, bitcoins are decentralized. There is no government/private agency, a monitoring authority or clearing house to monitor bitcoin flow. This makes the digital currency spendable nearly anywhere around the world.

Due to it being decentralized, Bitcoin is also dubbed as “the currency of internet”. This is because the Bitcoin transactions are not bound to any physical boundaries and can be sent to/received in any part of the world.

Is Bitcoin Anonymous?

Bitcoin transactions used to be completely anonymous. But now many bitcoin escrow service providers have started implementing KYC (Know Your Customers) and AML (Anti Money Laundering) regulations.

These regulations bound the users to provide proof of identity and residence which makes it harder to achieve anonymous transactions.

How Can You Use Bitcoins?

Bitcoins can be used in a similar fashion as traditional currency i.e. to buy/sell goods, services, and for investment purpose. Another use of bitcoin is to generate revenue through money transfer.

How to Earn Bitcoin?

There are two major ways to earn bitcoins: buying and mining.

Buying Bitcoins:

Bitcoin can be bought through many online exchanges. The exchanges operate on both local and global scale. You can also buy bitcoins from other people via LocalBitcoins.

Bitcoin Mining:

In Bitcoin mining, users on different computers assemble together to form a block and work to solve mathematical algorithms. Those who successfully solve the problems earn their reward in bitcoin.

Conclusion:

Bitcoin is well secured and the fact that Bitcoin transaction data cannot be deleted or tampered with makes it even more protected. Moreover, the currency is cost effective and many major corporations have shown their interest in accepting Bitcoin as payment. The future seems pretty cool!

Bitcoin Price Once Again Struggles to Sustain Momentum

Want create site? Find Free WordPress Themes and plugins.

Bitcoin price has rebounded from $6,500 to $7,034 with the market cap of $125 billion, at this very moment. Other smaller cryptocurrencies including VeChain and Steem have somehow surpassed bitcoin with a 50% and 25% surge in value, respectively, while other major cryptocurrencies like Ethereum, EOS, Bitcoin Cash, Ripple, and Litecoin have also performed quite well over the past few days.

bitcoin price surge

Bitcoin Price Surge

Since 30th March, bitcoin couldn’t surpass the $7,000 mark, due to its low volume.  However, on 25th March, Bitcoin price achieved $9,000, with comparatively strong volumes on the cryptocurrency exchanges. But since then, the price of bitcoin has seen a constant decline. Even though the price of Bitcoin went to $8,800 but then again, it failed to sustain momentum and its price fell to $6,400.

For surpassing the $7,500-mark, Bitcoin will have to sustain its volume for the next few days, then it will be able to move back to the $8,000 mark.  At this time, the RSI (Relative Strength Index) of bitcoin is at 39.2 however, earlier, it was at 30, indicating oversold situations. Bitcoin is currently being traded in a neutral zone, also the top-cryptocurrency hasn’t shown any overwhelming sell volumes.

Therefore, the next few days are going to be really important for bitcoin, as its value has increased over the past 48 hours, and according to bitcoin’s MACD (Moving Average Convergence Divergence), it has started to gain a little bit momentum.

Jon Matonis’s Views About Bitcoin

A well-known investor, an executive at VISA and the co-founder of Bitcoin Foundation, Jon Matonis, has stated that the entrance of financial institutions such as Goldman Sachs could lead to an increase in the demand towards bitcoin (in the mid-term). Different Bitcoin analysis are being done, but if the leading cryptocurrency can recuperate from its present bear cycle, then experts like Matonis are predicting a bull run for the top-cryptocurrency, Bitcoin.

Matonis said:

“I think it’s fabulous that they’re getting into it because it brings in new liquidity. They’re going to develop futures markets, options markets, I even think you’re going to start to see interest rate markets around bitcoin. We’re used to hearing things about Libor, the index for bitcoin interest rates is Bibor”

SEC Against ICOs

Also, according to the New York Times report, the ICO founders, called Centra, were arrested for defying US SEC (Securities and Exchange Commission) as they were distributing securities without getting any approval from the US Securities and Exchange Commission. If the SEC still keeps on curbing ICOs, it could lead to a wane in motion within the ICO ecosystem, globally.

Want create site? Find Free WordPress Themes and plugins.

2018 doesn’t seem to give a sign of relief to the cryptocurrency community as a latest press release by the RBI (Reserve Bank of India) has stirred up an unrestrained response, which is leading the cryptocurrency enthusiasts in a panic. RBI has been releasing warnings to the crypto-community related to the cryptocurrency in India and its risks, including:

  • Potential financial risks
  • Operational risks
  • Legal risks
  • Customer protection
  • Security related risks

cryptocurrency in indiaComing off the haze about the stance of government in distinguishing the ability of Blockchain technology and discovering its usage for abetting digital economy, the Finance Minister of Hon’ble in his ‘budget’ speech specified that cryptocurrencies are not identified as a legitimate tender, leaving an inexplicable uncertainty. Many in the crypto-community hailed the indication of “crypto” in the speech and took it to be an indirect sign for sanctioning the cryptocurrency trading, while others were nervous on the investment’s fate.

Risks Involved with Cryptocurrencies

Subsequently, the fury of RBI has stumbled now, and the crypto community has caught in another swirl of legal haphazard. The RBI’s press release accredited the potential of Blockchain in developing the efficacy of the financial system, though, at the same time it highlighted the perils that are involved with cryptocurrencies, such as:

  • Consumer protection
  • Market integrity
  • Money laundering

Furthermore, the RBI notified that the entities controlled by it will be prohibited from offering facilities to business entities or individuals, dealing with cryptocurrencies. Therefore, cryptocurrency investors won’t have the ability to transfer currency from their bank accounts to cryptocurrency trading wallets such as:

  • Zebpay
  • Coinsecure
  • Unocoin

Restriction on Banks

If it is supposed that the RBI pursues to save the over-all public from such perils, then it must specify the related reasons which turned out to be ground for issuing such a draconian direction. Quite the reverse, the RBI has put a total restriction on the banks to deal with business entities as a whole. The direction of the RBI pursues to paint all the entities in the cryptocurrency trade with the same brush, which can’t withstand the test of legitimate authenticity.

It is usually believed that the such encounters give escalation to the chances of development. At this current stage, the cryptocurrency community is required to keep patience and wait for the regulation to take its particular course as per other regions where the cryptocurrency is struggling to survive. The relating events will surely bring out the innovative avenues for the crypto-world in India.

Bitcoin Mining News – Some Bitcoin Miners can get Help from The Rise of Ethereum

Want create site? Find Free WordPress Themes and plugins.

Bitcoin Mining News:

Bitcoin mining is getting more difficult with the passage of time, so now it is taking more money and electricity to mine for the digital currency than ever before.

The rising worth of Ether, another digital currency, and the appreciation of Bitcoin can help to maintain the productivity of Bitcoin mining, in spite of increasing costs and difficulty.

It is becoming more difficult and problematic to mine bitcoins, but miners are not packing up their servers because of this. the number of available bitcoins for mining has decreased from 50 Bitcoin per block. According to a financial technology analytics service “NEXT”, the number of bitcoins available for mining was 12.5 Bitcoin per block when it initially came onto the scene.  According to a Bitcoin countdown site, this number has set to decrease about to 6 Bitcoin on June 19, 2020.

In the starting days of the technology, a few computer systems were able to mine hundreds of coins in about three to four days. Sebastian Quinn-Watson, a consultant with a bitcoin mining firm reveals that is not what the fall looks like today. Sebastian Quinn-Watson said, today, about 1700 bitcoins are generated per day. Basically, we all are fighting for about one coin every 10 minutes.

Quinn-Watson said the rise in the value of Ether is a trend which can help Bitcoin miners.

Ethereum on The Rise:

 

Ether is the most prominent rival of Bitcoin which is controlled by the Ethereum blockchain, Ether has gone high over 2000% since last year. Until the June, the digital currency was on its way to beat Bitcoin as the largest digital currency of the world, by market cap, according to Coindesk, since its market share has pulled back.

According to Sebastian Quinn-Watson, miners could get benefit from the future appreciation in the price of Bitcoin. If the appreciation of Bitcoin was to overtake the rise in the mining cost, then the productivity of the business will remain unaffected.

Business Inside Volatility:

 

To be sure, the price of Bitcoin is high about 250% since last year. But it has experienced recently extreme swings in its price. Some miners have credited this instability to current civil war between crypto-power brokers. This did not bother Sebastian Quinn-Watson, he told that the Business Inside instability or volatility is exciting. He said, we welcome the volatility and look at this as required aftershock of the Cambrian explosion which Blockchain.
