The first step to using a bitcoin is obviously to obtain a Bitcoin wallet address. Without it, you can’t send, receive or store bitcoins. So before you get bitcoins, you’ll have to buy, download or create a bitcoin wallet.

Your wallet acts as a personal interface to the Bitcoin network, which stores private keys that give you access to the bitcoins.

A Bitcoin wallet is basically an app, device or website that controls your private keys.

Different kinds of Bitcoin wallets

Different Types of Wallets:

There are different ways to use Bitcoins, so there are different types of Bitcoin wallets as well.

  • Online wallets – these can be accessed on the web from any Internet connected device.
  • Bitcoin hardware wallets – these are physical devices designed to store bitcoins.
  • Software wallets – these are applications that can be downloaded to your phone, computer or tablet.
  • Paper wallets – these are bitcoin private keys that are printed on paper from a computer.

Wallets secure funds by protecting our private keys.

Let’s discuss these types in a bit more detail.

Online Wallets:

Also known as Hot wallets are basically bitcoin wallets that are accessible on internet connected devices like mobile phones, tablets, and computers.

They can be accessed using a user-set password and store your private keys on the web.

Eg: – GreenAddress and SpectroCoin

    

The advantage of using online bitcoin wallets is that they can be accessed from anywhere in the world and are best of regular or frequent transactions. Although, it isn’t the best idea if you’re planning on storing your bitcoins for the long term. There is an issue with the security since the private key is entrusted to an online service, there could be a scenario where the whole database of the service would get hacked and you’d have to say goodbye to your holdings or the service gets hold of your account.

Thus, it is recommended that you opt for online wallets when it comes to more frequent transactions.

Hardware wallets:

These are physical devices built to generate bitcoin private keys offline. They keep private keys separate from internet connected devices and they are maintained in a secure offline environment.

The best and most popular BTC hardware wallets:

  • Ledger Nano S
  • KeepKey
  • Trezor

Hardware wallets are definitely a good choice if you’re considering factors like security and reliable storage of bitcoin. By generating private keys offline, you are able to ensure that hackers cannot access your bitcoins.

Even if the device ends up getting stolen it can be protected using a backup PIN code.

Software Wallets:

These are designed to be installed in computers and laptops. Only you will have access to the private keys that store your bitcoins.

Bitcoin Armory is the most secure, popular and stable software wallet.

Paper Wallets:

One of the safest ways to store bitcoins are Paper wallets, especially if you’re planning on keeping them for the long term. It basically involves printing the Bitcoin address and private key on a piece of paper.

Conclusion

These are a variety of options for you to choose from. It is your decision to choose what you find suitable for the storage of your coins.

What Is Bitcoin Hard Fork? The Most Heated Bitcoin Topic Explained!

Want create site? Find Free WordPress Themes and plugins.

To begin with, Bitcoin has been the talk of every news channel, tabloid, website, etc. for a long while now. It’s increasing popularity might’ve caused a little problem for the network. Bitcoin is in a messy situation right now and something needs to be done. Fortunately, two possible solutions have been proposed as well, but only one can exist.

 

bitcoin hard fork

 

What’s The Issue?

In simple words, Bitcoin is unable to withstand the number of transactions taking place on the network.

The technical explanation is that the 1MB block size limit which is programmed into the system has become a problem and is causing delays in the processing of transactions. Basically, a purchase can take from a few minutes to hours to confirm.

Two techniques were proposed, which result in two different solutions: Bitcoin Unlimited, and Segregated Witness. They’re both proposed software updates to the Bitcoin network with the aim to completely change the way Bitcoin functions.

Obviously, the two can’t coexist, that would “fork” the Bitcoin network – splitting it into two different digital currencies.

A fork is known as a software update. Basically, updating a program from an old version to a new one.

Hard Fork:

It is a compulsory software update that is required in order for the program to function.  It can be implemented to fix bug errors or any security issues present in the older version of the software. Also, a hard fork is irreversible.

The “hard fork” will split the blockchain, leading to the introduction of a new chain of transactions branching from the original one.

Bitcoin Unlimited:

Starting off with Bitcoin Unlimited, this proposal is favored majorly by Bitcoin miners. To understand this, you must know the concept of Bitcoin mining. Bitcoin miners use specified powerful computers to solve complex mathematical algorithms in order to verify a transaction and be rewarded with newly issued bitcoins.

We are aware that there is a built-in block size limit of 1MB in the Bitcoin network, however, BU gives miners the permission to vote on increasing the block size whenever they want. This gives them control of the Bitcoin network, due to which they’re favored by miners.

Segregated Witness:

On the other hand, SegWit is being voted by many Bitcoin enthusiasts and developers. Their aim is to optimize the Bitcoin coding in a way that allows them to decrease the transaction size and increase the transaction volume, all while sticking to the 1MB block limit. They suggest the use of a soft fork.

A soft fork is a software update that lets the network to adapt to the new functionalities and features implemented. The update doesn’t interfere with the existing software and the older version will still be usable.

Who Will Be The Winner?

Aha! Too bad we can’t answer this question because half the community goes for SegWit and the other half for BU. There’s not really much we can do, just voice out our opinion and educate others with whatever we learn and maybe help them come up with opinions of their own.

We’ll just have to patiently wait and watch how this turns out.

I’d like to point out that I have a very limited technical knowledge and only know my way around a few technical terminologies. This post is a compilation of weeks of research that I’ve put together myself. So, if you do find any errors, do let me know in the comment section below and I’ll be sure to check back on them.

Cryptocurrency Security – Here’s All About Its Three Layers!

Want create site? Find Free WordPress Themes and plugins.

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.

Bitcoin Spurs a Shortage of Graphic Card

Want create site? Find Free WordPress Themes and plugins.

The increasing popularity of Bitcoin is causing a prominent shortage in the supply of graphic cards. It is considered a key component of the digital currency system over the last few years.

The chief executive of JIB group of computers, known as a leading IT retail and computer gaming chain said that the price of graphic cards is also increasing since mid of May 2017.

Graphics cards are the main part of computer systems which used for mining the cryptocurrency like Bitcoin. People who invest in Bitcoin can get revenues on their investment from Bitcoin much faster than other investments. They can get returns of their investment within only 5 to 15 months.

A mining rig is a computer system which miners use for mining cryptocurrency. According to Mr. Somyot, people think investing in a mining rig is not very risky. They use minimum six graphic cards. At a price of almost 2940 USD, for a mining rig.

In gaming markets, the margin on graphic cards has also been increasing since the 2nd quarter this year, and it is about 2-3% to 8-10%. The graphic card companies need to reserve the cards to dodge a negative impact on gamers. In the markets, the demand for the graphics cards is also at a high point.

 

 

The most commonly used graphic card for Bitcoin are NVIDIA 1060 and 1070, and AMD 570 and 580. These were in short supply and causing a 20% price hike.

According to predictions, the higher prices will remain until October.

Don Sambandaraksa is a long time Bitcoin enthusiast associated with cryptocurrency since 2013 when the price of Bitcoin was at 40 USD, he said, these days Bitcoin may no longer be efficiently mined with CPUs or even GPUs (Graphics Processing Units).

He said people have made chips that could only do Bitcoin hashes, nothing else.

Mr. Don said, 1080Ti card’s price is about 700 USD and it can get a return on investment in almost 108 days. Over a year can make 2300 USD, an annual return on investment of about 300%. He said, as more people come to buy graphic cards then the less profitable they will be. Mr. Don also said it is a sign of the crazy levels of the profitability that mining offers.

What is a bitcoin wallet address?

Want create site? Find Free WordPress Themes and plugins.

If you’re having difficulty in understanding the difference between Bitcoin wallet and Bitcoin wallet address keep reading on to clarify your doubts.

Before we dive straight into the address bit, you need to understand what exactly a Bitcoin wallet is.

What is a bitcoin wallet address

A bitcoin “wallet” is basically a vault for your bitcoins. It contains all the information on your transaction history and balance.  It allows you to store, send and receive bitcoins.

There are two main types of wallets:

Software walletIt’s to be installed on your desktop or mobile. This wallet will be completely under your control and it is your choice what kind of software wallet you’d like to install.

Web walletIt is hosted by a third party and is usually quite user-friendly, but it is your call to trust the provider to maintain high levels of security to protect your bitcoins.

What is a bitcoin wallet address?

It is simply a unique 26-35-digit combination of letters and numbers and it looks something like this, 1ExAmpLe0FaBiTco1NADr3sSV5tsGaMF6hd

Addresses can be generated at random and free of cost by any Bitcoin user. You will use this address to receive and send bitcoins from your wallet. You are able to send bitcoins to someone, by sending it to their bitcoin address. However, for each payment request or invoice, a new bitcoin address is generated.

Your Bitcoin wallet address can also be represented as a QR code. If somebody wishes to send your Bitcoin, they can scan the code using their Bitcoin wallet and send Bitcoin to your wallet:

What is a bitcoin wallet address

Bitcoin addresses are created as part of a key generation process that creates a pair of keys. They are a matched set, where one is public and the other is private. When you “sign” a bitcoin address you are running the public and private keys through an algorithm that checks whether those keys belong together. Usually signing is talked about in the context of a message. Someone sends you a signed message and you can verify that the message came from the genuine person. You can verify the message because it was signed with their private key and you match it to their public key.

When sending bitcoins, the signed message is a portion of the bitcoin transaction and you do not explicitly see the message, it is just part of the transaction. This lets you validate the ownership of the address. The transaction was signed with the owner’s private key and you check that it’s valid using their public key. Bitcoin wallets usually contain this message signing and verification functionality.

Make sure you and only you control the private keys to your bitcoins!
