Blockchain Review

Blockchain technology is commonly linked with Bitcoin and other cryptocurrencies. However, that’s really on the tip of the iceberg. There are some people who think blockchain will possibly end up by transforming a number of important industries, politics and health care.

Whether you are just looking forward t invest in Bitcoin or trading some Ethereum or you are just curious about what the heck it really is, you are at the right place.

Understanding Blockchain Technology

Well, blockchain technology isn’t really simple when you dive deeper into the details. However, the basic idea isn’t so difficult to understand. It is an effective database which is validated by a large community, instead of a central authority. It works on a collection of records that has a lot of people give it the thumbs up, instead of relying on a single entity, similar to government or back, which most probably hosts data on a specific server.

Each block in the blockchain represents a large number of transactional records, and the chain component connects them all together with the help of a hash function. When records are created, they are confirmed by a distributed network of several computers and paired up with an entry which came earlier in the chain. Therefore, it results in creating a chain of blocks or in other words blockchain.

The entire blockchain is dependent on this wide network of computers which means that no one will have control over its history. Well, this is an important component to consider because it confirms everything that has happened in the chain earlier. Therefore, no one can go back and change the things in the blockchain. Consequently, it makes the blockchain a public ledger which can’t be tampered easily and gives it a built-in layer for protection. However, it isn’t achievable with a standard, centralized database of information.

Traditionally, we should need these central authorities to trust one another as well as fulfill the needs of contracts. Therefore, this technology makes it achievable for us to have our peers guarantee that in a secure automated fashion.

Where did it came from?

This technology has only been effectively implemented in the past decade. However, it roots can be traced back from the far past. In 1976, a paper on New Direction in Cryptography discussed this idea of a mutual distributed ledger and this is what this technology effectively works on. Later in 1990, it was built upon with a paper named as “How To Time-Stamp a Digital Document”. However, it will take another few decades and the combination of powerful modern systems, with the smart implementation with a cryptocurrency to makes these ideas more practical.

The blockchain makes use of complicated calculation in order to validate the blocks in the same way as a traditional private ledger. In turn it needs powerful systems, which are quite costly to buy, and keep them cool. This is the part of reason that why bitcoin acted as such a great beginning point for introducing this technology, because it can reward the people that are taking part in this process with something having financial value.

In 2009, Bitcoin made its first appearance in the global market as well as bringing together the classical idea of the mutual distributed ledger with a complete digital currency that wasn’t controlled by any single person or organization. It was developed by the “Satoshi Nakamoto” who is still effectively anonymous. However, the cryptocurrency introduced a method of making transaction while protecting them from any interference by making use of this technology.

What Is Blockchain Mining?

Although bitcoin and the other alternative currencies make use of this technology, they do this in different manners. However, Bitcoin was the invented first and it has undergone several changes at the command of its core developed and the larger community. All the other alt-coins have been introduced to improved upoin bitcoin and working on quite different ways.

When it comes to bitcoin, a new block in its chain is created around every ten minutes. Those block records, verify or certifies new transactions that have been processed. In order to let this happen miners make use of powerful computing hardware in order to provide proof of work. It is a calculation that efficiently generates a number of which verifies the transactions and block that it contains. However, many of these confirmations must be received before a bitcoin transaction can be effectively considered to complete, even if the actual bitcoin is technically transferred quickly.

There are various online platforms that are offering a chance to mine several coins online. Here is the list of few platforms that are offering you a chance to mine different coins. However, there are platforms that offer cloud mining.

Here is the list:

What Is Blockchain Wallet?

You need to have a reference point in order to make transactions regarding cryptocurrency by making use of blockchain technology. It can be in the form of a blockchain wallet, usually it is referred to as a bitcoin wallet. However, it is also famous as mobile wallet, cryptocurrency wallet and many other names.

Before you get confused by the names, you need to know that it’s not really an actual physical wallet that keeps your money. It is a reference point which is linked with an application that you can use to manage your transactions. This wallet only keeps your private key secure which is an important part of your transactions. However, without a private key, you will not be able to buy, trade or sell your bitcoin. If someone hacks your private key, they will be able to performs all the actions that are mentioned above.

Generally, you don’t really store your bitcoin anywhere but the key to access your coins is your private key. It can be stored securely and safely in your wallet.

Different Types of Wallets

There are many different wallets to suit your various needs and security needs. However, the range of these wallets is usually divided into the following types of wallets:

  • Hardware wallets
  • Paper wallets
  • Mobile wallets
  • Desktop wallets

Paper Wallets

As the name suggests, it is a printed record of your private key which can be stored offline at a place of your choice. It is an option which is favored by people who are afraid to get hacked in the online environment.

Mobile Wallet

These wallets are linked to a mobile application which allows you to manage your transactions by making use of your phone from anywhere.

Desktop Wallets

These wallets are also connected with an application, but they are desktop based. It will provide a limitation regarding not being able to manage or make transactions from anywhere.

Hardware Wallets

These wallets are the height of blockchain wallet security. These wallets are the separate devices which can be connected with your desktop by making use of USB when you need to make transactions. However, all the pertinent information stays within the device and they can’t be hacked or removed.

There are many types of these wallets. Some of them can also hold your altcoins for you.

Here are few wallets:

  • Coinomi: It is the most popular wallet when it comes to store cryptocurrency. It is designed for mobile Android and iOS. It is able to support more than 100 coins.
  • Daedalus:Daedalus is software based which is also available for desktops like Windows or Mac OS. It is able to support Cardano cryptocurrency.
  • Trezor: It is another hardware wallet used to store cryptocurrency. It is able to support all coins ERC-20 type and 15 other coins.
  • Blockchain Wallet:It is another secure and good wallet for storing Bitcoin and Ethereum.
  • MyEtherWallet: It is a free wallet for storing Ethereum.
  • LedgerNanoS:It is a hardware wallet. However, it is expensive but it offers great security. This one is highly recommended to keep your cryptocurrency safe.
  • AirBitz:It was founded back in 2013 in California. It is trusted by millions of users because it is very safe and secure.

  • Exodus:It is another cryptocurrency wallet which can be used for storing over 30 different types of coins.
  • Enjin: It is another secure mobile wallet which can be used for storing 12 different types of cryptocurrencies and ERC-20 tokens.

Blockchain Technology For Beginners

This technology has a lot of exciting potential to offer. However, there are some serious factors to consider before we can assume that it is the technology of the future.

Do you know about all that computing power required for verifying transactions? Those computers need heavy load of electricity. However, bitcoin is a poster child of the challenging growth in power demanded from a large network of blockchain. However, it is difficult to get the exact statistics on the power requirements. In its current state, it is regularly compared to small countries.

That is not engaging given the present worries about environmental change, the accessibility of energy in creating nations, and dependability of energy in created countries. Transaction speed is also an issue. As we noted above, hinders in a chain must be verified by the distributed system, and that can require some serious energy. A great deal of time. At its more awful, bitcoin’s normal transaction time surpassed 41 hours. Ethereum is significantly more productive, but its normal time is around 15 seconds — which would be an unfathomable length of time in a checkout line at your nearby grocery store. Blockchains utilized for purposes other than cryptographic money could keep running into comparative issues. You can envision how disappointing it is hold up 15 seconds each time you needed to change a database passage.

These issues should be settled as blockchain turns out to be more prominent. However, considering we’re not as much as a decade on from the blockchain’s first usage, and we’re as of now making a course for growing new uses for it, we stay idealistic that those included will work out it.

Explaining Blockchain

The blockchain is the thing that makes bitcoin work. The arrangement of digital currency would not exist without the straightforwardness and powerful security of the blockchain. It’s fundamentally an open, distributed record that houses all the bitcoin transactions at any point made ever. Because it is distributed over different PCs, it can’t be modified retroactively without the adjustment of each record, making it in the same class as difficult to hack into and change transactions. Each time a transaction happens, it is added to the blockchain as another square in the chain. The blockchain is the motivation behind why there is no requirement for a go between or focal administration framework to deal with all transactions, consequently the reason it has contributed to making bitcoin so mainstream.

The innovation of the blockchain is intelligent to the point, that standard banks and significant businesses are altogether searching for approaches to consolidate the innovation into their own businesses. Watch this space because this could be the method for future banking over the globe.


Blockchain is gaining popularity among people day by day. Many people are looking forward to invest in this technology. However, it has given birth to different investment and money earning opportunities for people. People are showing a great interest in mining different types of coins. There are various online platforms that are offering a chance to people to contribute in mining and earn for their contributions. However, there are also some cloud mining platforms that are offering opportunities for people to mine without purchasing any kind of hardware. It is a complicated technology but it isn’t difficult to understand the concept as it works on the principle of blocks. You will get rewards for contributing in the mining. It is a long term investment opportunity which people can rely on.
