Today world is witnessing the advent of blockchain technology for providing solutions to many of the problems faced by individuals in various sectors. Blockchain technology has proved to be a boon in optimising processes in industries such as insurance, finance, healthcare, telecom and many more. Due to the potential to streamline business process, providing data security, transparency and fraud elimination, this breakthrough technology can prove to be the technological backbone of the e-commerce industry.

The e-commerce industry is growing at a massive scale and so does the issues related to it. Since its inception, the e-commerce industry has faced issues related to secure financial transactions, customer data security, supply chain management, transparency etc. RecordsKeeper Blockchain can undoubtedly be seen as a one fix solution to all these issues E-commerce industry is facing today.

Payments

The most Important challenge today encountered by e-commerce industry is payment related issues. Payment solutions for international e-commerce certainly need improvements as current payment methods to include payment of high payment processing fees. Along with payment processing fee, a high fee that is usually 2-3% of the total purchase price of any transaction is charged by e-commerce platforms on any sales made by retailers using their platform. RecordsKeeper can eliminate the high payment processing fee. RecordsKeeper blockchain can create a blockchain based marketplace with low-cost financial transactions and high-security standards.

 

Supply Chain Management

Friction in the supply chain is a huge pain for the e-commerce industry. Payment delays between a manufacturer and a supplier, or a customer and a vendor, contracts handled by lawyers and bankers aiding to the cost and delay, hard to trace shipments, all add to the complexity. RecordsKeeper blockchain can eliminate these issues by providing incorruptible visualisation of the supply chain process. An incorruptible blockchain such as RecordsKeeper network can provide a transparent supply chain enabling consumers to see the order flow of the purchased products.

Trusting Blockchain exchange

With every passing week, the world’s interest in Cryptocurrencies is multiplying at a staggering rate. Whether it’s bitcoin, ether, or any any other cryptocurrency on the block – people around the world own and trade cryptocurrencies. To make the trading accessible to the general public, we’ve several cryptocurrency exchanges on the world wide web. Through these exchanges, anyone can buy, sell, or exchange cryptocurrencies either with other digital-based currencies or with traditional currency such as rupee or US dollar.

Types of Exchanges

There are three categories of cryptocurrency exchanges. They’re as follows:

Brokers – Through these brokers, anyone can go and buy the desired cryptocurrency at a preset price. Most of these cryptocurrency brokers are similar in function as foreign currency exchanges.

Platforms for Trading – These platforms specialize in connecting buyers and sellers. For every transaction that takes place through the platform, they charge a fee — which is also how they make money.

Direct Trading – The way direct trading differs from the other two is that there’s no fixed price. The seller decides the amount, and the buyers have to determine if they want to buy or negotiate for any particular cryptocurrency. Direct trading is usually peer-to-peer.

What are the key attributes to look at while deciding to Trust a blockchain exchange?

The meteoric rise of bitcoin has also contributed to a significant increase in con-artists and exchanges which are mostly scams. So, before you decide to put your hard-earned money to buy cryptocurrencies — it is crucial to do your research. Below are the three things to know about an exchange before trusting them.

Reputation: In the age of the Internet, it’s not too hard to find reputable reviews about anything — including blockchain exchanges. Right from forums to commercially reviewed websites, you’ll find loads of information that’ll make it easier for you to decide whether an exchange is a right fit for you or not.

Fees: Before you even think about joining an exchange, do make sure you’re well-aware of all forms of costs that the exchange charges. The fee-model should include comprehensive details regarding withdrawal, deposit, as well as transactional fees. Compare it with other exchanges and then make an informed decision.

Verification systems: Any exchange worth its salt will have strong fortification in the form user verifications and securities. While the exhaustiveness of the verification might seem annoying while registering, it’ll protect your cryptocurrency and money from all sorts of scams.

Some well-known and reputable exchanges

We’ll make it even easier for you. Based on our research and user reviews, we’re going to tell you our favorite two blockchain exchanges that you can trust without worry.

Coinsquare: The first thing you should know about coinsquare is that it’s built on the same technology as the New York Stock Exchange. Yes, that’s right. According to their website, they manage their ledger at least 2346 times in a single day to ensure security. Reputable and secured, Coinsquare is a popular choice for both crypto-veterans and beginners alike.

Coinbase: Not only is Coinbase backed by some of the world’s best investors, but it’s also trusted as an exchange by millions already. One of the key features of coinbase is that coinbase insurance covers the stored currency. So, there’s that added layer of security. There’s a digital wallet also available as a mobile platform through which users purchase bitcoin, ether, and even litecoin.

Discovering Blockchain Loopholes

There’s no doubt on the potential that the blockchain technology has to offer. The world has accepted it at large. Blockchain developers are solving multiple problems across industries with this technology.

But there’s another side to the story wherein the hype is shadowing real implementation issues with the blockchain. These issues hinder the mass-adoption of this world-changing technology.

There’s no doubt that we’ll eventually get to the point wherein we’ve explored this great technology. However, to be able to that it’s essential to face realities both as developers and enthusiasts of the blockchain.  

Below we’ll be mentioning four implementation issues that plague blockchain as of today.

Limited Scalability –

One of the key advantages of the blockchain technology is decentralization. However, it comes at the cost scalability. As the number of transactions increase (and since every transaction passes through each block), the requirement increases too. Eventually, it’s not possible for every node to participate and the resources to process each block then rests with a limited few. However, that potentially compromises on the decentralization aspect of the blockchain. Scalability is probably the number one barrier when it comes to blockchain adaptability.


Storage Constraints –

Almost every application that’s built on the blockchain will require some form of storage. It can be either to store user identities, or it can be to record specific financial as well legal data. However, by property traits, every node stores the data. Along with it, no data will be able to be removed regardless of whether it’s needed or not. The above two cases put a considerable cost to the storage operation when it comes to the blockchain. Thus, storage constraint is a massive hurdle for any application to be able to build on the blockchain.


Lack of standards and governance –

No central authority governs public blockchain. While that’s great to build a trustless and open, it has its disadvantages. First, one is that there’s no who’s responsible for maintaining and upgrading the systems most efficiently. Even if some developers band up to create an organization, it leads to some form of centralization (take the instance of the Ethereum foundation.) However, we can’t even leave it completely open as over the years it’s proven ineffective on multiple levels.


Poverty in Available Tooling –

For any developer to work effectively and efficiently, the first requirement is adequate tooling. If inadequate, the developers can’t do much even with the best of the intentions. As a matter of factor, the currently available pool of tooling is not good enough, even for the most seasoned of the developers. Right from good testing frameworks to security auditing and even right blockchain analytical tool — the available tooling to a blockchain developer is severely limited. Along with hindering the potential of the technology, it also demotivates enthusiasts.

Conclusion:

Unfortunately, the hype makes blockchain appear invincible when the fact is that there’s a lot of work left. So, instead of making the technology glamorous, we need to focus on how to solve core implementation issues with the blockchain.

There’s not even an iota of doubt that blockchain is here to stay. However, the issues mentioned above and many more are not letting the technology become mainstream. It’s on us now — the developers, the investors, the blockchain enthusiasts — to work towards a unified vision.

How RecordsKeeper Blockchain Can Help in Preventing CBSE Exam Leak

Recently we came across a major story about the CBSE paper leak from various sources. Those who had access to the exam papers charged Rs. 35,000 per paper and even some parents took part in it by reselling the papers to others to cover their cost. Thus the leaked papers were available upto Rs. 5,000.

This caused a huge uproar among the students which led to a re-examination. The current investigation is currently focusing on the role of CBSE officials, invigilators and school staff, coaching centres and printers. The leaked Economics paper was being circulated on social media for several hours before the test started on Monday. The Delhi government also reported that it received complaints from the CBSE about the Class 12 Accountancy paper being leaked too.

The past months saw many downs for the education system in India and challenged the way we share information in our country. This whole fiasco could had been resolved if the education system was driven by the power of Cryptography and Blockchain. We at RecordsKeeper thrives on latest technology and the power of Blockchain. This specific use case is the prime example of where RecordsKeeper comes into play and provide the utmost security in the shared information world.

RecordsKeeper: What is it?

RecordsKeeper is an open source platform for open record keeping & data security. Using RecordsKeeper’s public Blockchain anyone can publish a key-value pair of records which are immutable & verifiable.

Let’s discuss some of the major problems and how RecordsKeeper can solve them with respect to the CBSE paper leak.

  • Multiple mediums present for the exam paper

Currently the CBSE paper is presented in multiple mediums which gives a person with authority to take it out and sell over the black market without being noticed. Using RecordsKeeper as the storing medium for the exam papers, it limits the exam paper presence on multiple mediums. Once the exam paper is over RecordsKeeper Blockchain then there is only one single medium of shared ledger available.

  • Hacking of central storage

If the CBSE exam is shared over some relational Database or central storage then there is always a possibility of a malicious attacker trying to access the information or Denial-of-Service (aka DoS) attack but with the use of RecordsKeeper Blockchain we can provide immutability and security for the same. Once the exam paper is over the RecordsKeeper Blockchain, it cannot be modified, deleted or tampered. Moreover the security is provided with the Cryptographic algorithms being used with RecordsKeeper where you can encrypt the exam paper and store it over the RecordsKeeper Public Blockchain. As the RecordsKeeper network is made up of multiple peer-to-peer nodes, there is no central storage available for conducting Denial-of-Service attack as all the the nodes are synchronized with each other.

  • Authorities leaked the exam paper

The major concern point of the CBSE exam paper leak was that the authorities who had access to the exam papers were the focal point for the leak of the exam paper. RecordsKeeper provides a solution to this in a very neat and effective technological way. In RecordsKeeper, everyone who has access to the Blockchain has their own private-public key pairs. Everyone – be it schools/students/authorities/agencies can create a private-public key pairs. The CBSE board can have multiple private-public key pairs for different exam papers. Now the private key is to be securely kept with the person but they can share their public key to the rest of the world. In our scenario, the following path can be taken to solve the problem.

  • CBSE board generates a key pair for each exam.
  • The people/agencies who need the access to the paper can share their public keys through secure internal channels with the CBSE or the CBSE board themselves can generate key pairs for all the schools who require the access to exam papers and share it with them. This process can be online & automated.
  • The exam paper (in JSON/XML Format) is encrypted using the exam private key by the CBSE board. (First Encryption)
  • After that, once the head of CBSE has all the public keys of different schools then they can encrypt the exam paper again (second encryption) by the school’s public key to make sure that only the school registered with the CBSE only has access to the exam paper through their respective private keys. Here the public-key of the respective school needs to be the part of the exam itself to trace back school easily in-case of any leak.
  • The encrypted exam paper is published over the RecordsKeeper blockchain along with . This will create multiple transactions entry over the RecordsKeeper for individual school. There may be 30,000-40,000 CBSE Schools all over the country.
  • The uploaded exam paper’s record identification key is shared with all the respective schools once it is uploaded over the RecordsKeeper Blockchain. This will ensure that they all have the encrypted exam paper ontime. Ideally can be done 24-48 hours before the exam. Now the magic of RecordsKeeper comes into play – the school have the access to the exam paper through their respective individual recorded transaction and they can decrypt the exam paper using their own private key. Please note they will still not able to access the exam as it is also encrypted by CBSE’s private key & they need the public key of the CBSE to decrypt it.
  • This way of uploading data over the RecordsKeeper Blockchain provides a way for the CBSE board to monitor the access of the exam papers and it also makes sure that the exam is not reached to an unwanted party.
  • CBSE announces the exam public key just before the exam. May be 30 minutes or so.
  • The authorities now can decrypt the exam using the exam public key. Convert it into printable format using simple tools like JSON/XML to PDF converter.
  • Finally the exam paper is distributed to the students.

Please note each paper will have the public-key or record-key of the school printed in small letters (in background, like water mark) of the question paper all over the question paper. Not at just one corner or page of the exam paper. This will easily allow the regulators or investigators to trace the school in case of any leak. Since only the principal will have the access of the private key pinpointing the human will be much easier.

Using RecordsKeeper Blockchain to distribute exam makes sure that every activity is being tracked and if somebody tries to maliciously access the paper then it will be recorded over the RecordsKeeper Blockchain and the culprit can apprehended as soon as he/she tries to access the exam paper.

We can take a step further in security by creating the key pairs for students and with that the students will have direct access to the exam without any 3rd party mediums and dependencies.

RecordsKeeper is here to make sure we change the way we share information and with its use we can uplift the security, immutability and transparency in our education industry.

Breaking Blockchain Conjecture

Our political, economic, as well as legal environment structures itself in the form of contracts, transactions, and its record. It is a system as old as time with evidence of world’s first civilizations too creating a system to keep track. Along with verifying identities and making a note of the exchange, these records serve as history also in many ways.

However, these systems that held on for centuries are shaking in the face of digital transformation. The processes have just not been able to keep up with the pace with which the world is evolving. In this digital era, like most things, the way we maintain these tools along with its execution also needs to change.

Where does Blockchain come into the picture?

Experts believe that blockchain is the solution. Blockchain, as a technology, resides at the crux of Bitcoin along with what’ve now become other virtual cryptocurrencies. In layman’s words, blockchain is a distributed ledger. Being open, it records peer-to-peer transactions without including third-party intermediaries. It promises data immutability along with its permanency. Verifiable data and records form the network. In fact, as the technology evolves, there are concepts such as ‘Smart Contracts’ that can even trigger transactions automatically.

What’s all the Hype About?

More than anything else, blockchain shows a glimpse of the world could be. A system wherein transactions are recorded, stored, and verified on a digital network. Every record has a timestamp along with a signature, and no data can be tempered with, recreated, or in any way corrupted. A self-sustaining system to the point where intermediaries like lawyers, brokers, and bankers will not be needed anymore. Different parties will transact directly with another with little or no friction whatsoever. That is the vision that blockchain promises.

Will Blockchain Live up to the Expectations?

By now, every business has heard that Blockchain will revolutionize everything in the coming few years. Moreover, while we share the vision of this technology, we think we might overstretching our expectations from Blockchain. Not only blockchain as a technology is in its nascent stage, but there are also security issues that seriously need to be pondered upon. However, the critical thing is that blockchain is a foundational technology. By foundational technology, we mean that several other structures (political, legal, financial) can be evolved and created with it. However, that just might take decades.

So, what should we expect from Blockchain?

There’s little doubt about the potential that this technology holds. In fact, in some industries like finance and healthcare, we already see its impact. The future result will be even more enormous; however, it will not happen next year or even in five years. It will take its own time to slowly but steadily seep into all our structures for good and to change it from within. So while we continue to marvel at the potential, we should also continue to innovate and explore it at this stage.

Conclusion:

The blockchain is here to stay. However, the world needs to start small to correctly understand and structure how and in what ways do we want to evolve Blockchain. The level of development of it will also depend on how effectively it adapts to the ever-changing need of multiple industries. For now, we know that blockchain is going to affect both your business and your world. As for when – the time will have to tell.

Blockchain consensus protocols and how to use them?

A consensus is a dynamic way to reach an agreement in a group. It is done with an aim to benefit the entire group as a whole. The method through which consensus decision-making is achieved is called “consensus mechanism.”

Now, which consensus protocols should be used for a wavering entity like blockchain?

As understood, blockchain is a decentralized peer-to-peer ledger without a central authority or a leader controlling it.  It creates a system which is devoid of corruption from a single source. In blockchain, independent nodes in the network must come to a consensus on the ledger status. This consensus mechanism ensures that all participants of a distributed ledger are on the same page.

Below are some standard consensus protocols used in the crypto space and their working:

Proof-of-Work ( PoW )

Bitcoin’s creator, Satoshi Nakamoto, invented the proof-of-work protocol. Going by the protocol’s name, the mechanism requires nodes to prove the work that has been done to have the right to add a new transaction to the blockchain. The transactions are done by ‘miners’ who solve cryptographic puzzles to “mine” a block to add to the blockchain. When a miner solves the puzzle, they present their block to the network for verification and in turn receiving the newly created cryptocurrency unit provided by the protocol as a reward. This entire process is energy intensive as it involves the nodes hashing data through high-performance, application-specific integrated circuit (ASIC) chips. Proof-of-work involves high computation energy and electricity which makes it an expensive process.

Proof-of-Stake ( PoS )

Proof-of-stake differs from the proof-of-work protocol. In this consensus algorithm, mining new blocks become easier for those who hold the highest amounts of the cryptocurrency. In other words, a proof-of-stake system requires the user to show ownership of a certain number of cryptocurrency units. The miners or creators of the new block are chosen randomly. It depends on the user’s wealth, also defined as ‘stake.’ In the proof of stake system, blocks are said to be ‘forged’ or ‘minted,’ not mine. Forgers are referred to users who validate transactions and create new blocks in this system. Validation of a transaction and creation of a new block requires the forgers to put their coins at ‘stake.’ Proof of stake protocol is a lot more resource-friendly than proof-of-work.

Proof-of-Capacity (PoC)

Proof-of-Space or proof of capacity algorithm uses the existing free space on hard drive to mine coins. Its very nature makes it more decentralized and low on power usage. Assigning more hard drive space will allow users to have more “plots” of data. The nodes receive a reward in the form of the native coin depending on the space made available by the nodes to the network.

Proof-of-Burn ( PoB)

Proof-of-Burn is consensus protocol which is an alternative to Proof-of-Work and Proof-of-Stake. In this algorithm, the coins are sent by the miners to an unspendable address ( eater address), and efficiently burning them. The burnt coins cannot be accessed an spent again. The idea behind burning a cryptocurrency is that the user is willing to undergo a short-term loss for a more long-term investment. Users are rewarded over time as they earn a lifetime privilege to mine on the system. The more coins a user burns, the higher the chance he or she will have of mining the next block. Proof-of-burn works like virtual mining.

Delegated Byzantine Fault Tolerance (DBFT)

The Byzantine alternative or distributed Byzantine Fault Tolerance algorithm is named after the Byzantine Generals problem. It addresses the issue of achieving consensus in distributed systems. DBFT recognizes two kinds of participants in the blockchain ecosystem: professional node operators or bookkeeping nodes, who run nodes to make money; and users who are just interested in making use of the blockchain. Delegated Byzantine Fault Tolerance utilizes this division of labor to provide better security for blockchains. The professional node broadcasts its version of the blockchain to the network. If 66% of the other nodes agree with the information, a consensus is achieved. When the consensus is not reached, there is an appointment of a different professional node broadcast its blockchain version until a consensus can be established.

Centralized vs Decentralized Blockchain

Blockchains have garnered interest from investors from all over the world due to their incredible promise of being an incorruptible ledger. When most people think of blockchains, they are referring to the decentralized or public blockchains like Bitcoin which anyone can access and participate in. However, blockchain technology is not limited to being just decentralized as the centralized or private blockchains also have some advantages for corporations over the public ones. Private blockchains are useful for corporations who want to use the power of decentralized ledgers to improve the ongoing function. Let’s take a look at an in-depth comparison of public and private blockchains.

 

Similarities Between Centralized and Decentralized Blockchains

From a technological standpoint, both centralized and decentralized blockchains are very similar as both are distributed peer to peer networks where every node is responsible for storing and securing the shared ledger. Both public and private blockchains require a consensus mechanism (like proof-of-work or proof-of-stake) among nodes to establish a single ledger. Both of these types of blockchains also have to provide upper and lower bounds on the security and efficiency of the network.

 

Differences Between Centralized and Decentralized Blockchains

The biggest factor that differentiates public blockchains from private ones is the pool of nodes that can participate in the network, and make administrative changes to the network. So, for example, Bitcoin which is the largest public blockchain in the world has no barrier to entry when it comes to accessing the ledger and sharing computer power to execute its proof of work algorithm. By contrast, IBM’s HyperLedger Fabric is more customizable in the sense that the organization that is deploying the blockchain has a say in every aspect of blockchain participation. Private blockchains are typically more restrictive in who they allow making changes to the ledger as they use the blockchain for the internal records.

 

Advantages of Decentralized Blockchains

Decentralized blockchains like Bitcoin, which is the most popular blockchain in the world, have very high security because of the enormous amount of mining resources that go in to secure the network. That means to coordinate a successful attack on the Bitcoin network; a malicious actor would have to acquire a massive amount of resources which is economically unviable. Another advantage is that anyone can use the network to send funds to any part of the world without going through an intermediary.

 

Disadvantages of Decentralized Blockchains

Due to their public nature, public blockchains like Bitcoin are susceptible to all kinds of analyses that can reveal more information about the network participants making the blockchain less private. The massive amount of miners mining on the network means that difficulty needs to keep increasing thereby leading to mostly useless computations done by miners to outcompete each other. It is estimated that every Bitcoin transaction costs about as much electricity that is required to power an average home for eight days. Therefore public ledgers are not very environment-friendly.

 

Advantages of Centralized Blockchains

Centralized blockchains offer much more customizability and control over the network to the organization deploying it as they can decide who gets to participate in the network. That means that not as much resources have to be invested in competing to secure the network which makes Centralized Blockchains more environment-friendly compared to their Decentralized counterparts. This also means that they have higher overall throughput because they get to decide the hardware that the network runs on. In practice, this means that corporations could use private blockchains to store sensitive information among nodes that they trust. This allows them to use the incredible power of blockchains without having to make the sensitive information public.

 

Disadvantages of Centralized Blockchains

Since there is not as much computing power securing the network as in the case of decentralized blockchains, centralized blockchains are less secure. It only requires a few of the nodes hosting the network to collude by amassing enough resources to hack the network. Also, since transactions are not publically viewable, it is harder to verify the authenticity of the transactions for an outside party. Also since private ledgers are not available for public use, they are of little use to anyone besides the corporations that deploy them.

 

 

Common Misconceptions about Blockchain

The market is abuzz with the advent of the blockchain. It has now become a ‘term’ which evokes strong public opinion, comments- whether valid or not. Let us begin by understanding the term blockchain. In simple terms, blockchain is a technology that serves as an alternative to centralized data storage. Instead of the data being stored on one or multiple servers which are prone to hacks, blockchain is distributed among computers. Radically challenging the status quo, blockchain works on a peer-to-peer verification of transactions. It allows for complete transparency as no single entity can possess the system.

However, the contemporary era is always ‘high’ on misconceptions surrounding any innovation. Just like the introduction of smartphones and internet dazzled the market and ‘legendary myths’ engulfed the mass, the world of blockchain has already created a lot of misconception.

DEBUNKING MYTHS

● The existence of the only Blockchain. Nooooo!

This belief is conclusively false. Although blockchain is commonly compared to the internet, unlike the internet, there are numerous blockchain- each designed to serve a distinct purpose. The common denominator is that they are distributed, have some form of consensus mechanism. Examples could be Bitcoin’s blockchain, ethereum, hyperledger, IBM and Microsoft blockchain, etc.

● Blockchain applications are used for criminal activities. Nooooo!

The collective mass is tied to the belief of cryptocurrencies supporting nefarious activities. It has its roots in the silk road and the dark web along with the mistaken belief of blockchains offering anonymity. While it is true that, to an extent, cryptocurrencies are a virtual boon for drug-trafficking, illegal pornography, and even terrorism, it’s ignorant to assume that it is an untraceable underworld enabler. On the open side, cryptocurrencies are a means to exchange digital assets. Bitcoin being a public ledger, there is always a record of any transaction taking place. The transactions can be traced anytime, anywhere, regardless the purpose of the transaction.

● Blockchain and bitcoin can be used interchangeably. Nooooo!

For beginners and most of the mass, blockchain is always understood as bitcoin and vice versa, creating a lot of confusion.
The blockchain was born with bitcoin, as the underlying technology. Simply put, blockchain is a technology whereas bitcoin is the application based on this technology. What bitcoin is to blockchain is what email is to the internet – its first ‘killer app.’

● All the Blockchains are public. Nooooo!

It is true that bitcoin, along with many well-known blockchains are public, but not all blockchains are. There exist private and semi-private blockchains with varying degrees of penetrability, approachability, and transparency. A public blockchain is open to the public where all the transactions are visible, and anyone can participate at any level. On a private blockchain, only parties with necessary keys can review private transactions. Technically, public blockchains utilize proof-of-work methodology whereas private blockchains use proof-of-stake.

● The Blockchain acts as magical data storage in the cloud. Nooooo!

The working of blockchain and cloud are poles apart. The common misconception is due to their intangibility. A blockchain doesn’t store physical information like PDF files or a word documents. It only provides for a proof-of-existence. Blockchain, conceptually, is a flat file, a linear list of simple transaction records. This ‘flat file’ holds code that certifies the existence of a particular document and not the document itself.

● The Blockchain is used only in the financial sector. Nooooo!

Blockchain technology was highlighted because of the introduction of bitcoin, its first application. Blockchain can be used in numerous areas referencing its implementation; finance incontestably is one of them. In fact, the Indian government is looking forward to employing the blockchain technology in education, health, and agriculture to fulfill its aim of India going truly digital.

● Cryptocurrencies are a replacement to traditional currencies. Nooooo!

As no single entity, corporation or a nation owns or controls the blockchain, it is often hailed as a revolutionary technology. With financial intermediaries,a.k.a middlemen flocking every sphere of our lives, this technology might bring in a new global economy. However, it is unlikely to happen, not anytime soon. The reason accounts for the exorbitant cost of mining, and also that blockchains are not scalable or efficient enough to support global usage. The difference can be seen in the duration of the transaction. Bitcoin can process a maximum of seven transactions a second whereas Visa can process thousands of transactions a second.

The blockchain technology is very much in its nascent stage- or experimental, according to some. The misconceptions mentioned above are few of many, and debunking such myths will provide a field for developers and researchers to produce more viable and efficient solutions. The blockchain technology can transform the society at all the levels. All we need is exploration and experimentation with the aim of a new invention.
