    Enroll Now: Free Blockchain Course. In order to understand the future potential of blockchain technology, it is important to understand the technology first. For example, customers showcase different behaviors and could fall into same patterns upon closer reflection.

    Artificial intelligence capabilities in modern technology enable it to store and analyze inputs for rendering results that match the typical consumption patterns of customers. So, you can notice that eCommerce sites like Amazon and rental apps such as Uber use customer data and leverage it for driving customers to make repeated purchases.

    Now, blockchain is future because it completely changes this mechanism and takes away intermediaries like Uber or Amazon. On the contrary, it provides users the capability to store information that a service provider could access without any intermediary.

    Blockchain technology basically introduces democracy in the process of sharing and accessing data throughout the world. You can think of blockchain as just a chain of blocks, in the literal sense, with the blocks serving as repositories for information. Users enter information into blocks and are updated in the block as nodes or records after every computer on the cluster verifies the block.

    As a result, data remains unique and secure while imposing zero transaction fees. So, one can clearly notice the potential of blockchain for improving transparency and reducing overall costs. The next important aspect of blockchain technology that can explain its potential as a futuristic technology is its working. Let us think of it as a network of databases with common ownership or spreadsheets.

    The spreadsheet is commonly managed and has access privileges for multiple networks with authorization. In the case of blockchain, you have to share spreadsheets with desired recipients while the relevant stakeholders have common ownership of the spreadsheet.

    If you make any changes in the spreadsheet, then other parties in the network have to verify them. Blockchain technology also enables hosting of the database through multiple computers on the network. Therefore, blockchain is future of technology on the basis of decentralization apart from immutability and transparency.

    Blockchain technology includes the use of peer to peer networks for chaining the blocks of data together to enable direct client-server access. When you enter information into a block, the nodes collect the data and secure it with hash functions. The node also distributes the information and related tasks throughout various networks, thereby promoting collective ownership among blocks in the network.

    Learn more about How Blockchain Works! Another traditional example of the working of blockchain can also provide additional insights on how blockchain is future of technology.

    Banks have been the traditional institutions for financial transactions. In the digital era, the lengthy processes have been replaced with payment channels such as Google Pay or PayTM. Blockchain technology takes away the need for taking your payment through the banks or portals and helps you make direct money transfers. The facility of such convenience in executing financial transactions with trust would be a prominent factor in driving the popularity of blockchain in the future.

    Talking about the future, it is better to rely on some prediction to understand how blockchain is future of technology. Here are some of the market predictions and statistics that make market analysts and economics term blockchain as the future.

    Therefore, one can clearly notice that blockchain is future of technology for almost every sector. Internet of Things, governance, stock trading, and supply chain operations- blockchain is making its market everywhere. In the long run, blockchain continuous innovation would result in long-term interventions of blockchain for all aspects of daily lives. At the same time, blockchain would be a prominent tool for disruption across different industries. Gartner estimates that blockchain is future of technology due to the rapid development.

    According to Gartner, general blockchain platforms would facilitate interoperability, ease of use and access, scalability and support for trusted private transactions. Furthermore, blockchain would continue to present better opportunities for enterprises to address their concerns about data confidentiality. At present, the above-mentioned trends showcase the potential future of blockchain and its role as a disruptive technology.

    After achieving these steps, permissioned blockchains and public blockchains may come together in the future.

    5 Blockchain Developments Coming in 2018

    Blockchain is one of the most promising technologies that assures to revolutionise areas such as finance and logistics. As a matter of fact, the year has witnessed several blockchain developments — in this article, we would track some of these major developments, arranged in no particular order. This year, Tamil Nadu became the first Indian state to introduce its own ethical artificial intelligence, cybersecurity, and blockchain policies.

    This announcement was made by state chief minister Edapaddi K Palaniswami during the Valedictory session of Connect Named as the Tamil Nadu Blockchain Policy of , its goals would be to project Tamil Nadu as a global blockchain leader — using blockchain policies in government services and processes to bring accountability; generating awareness on blockchain among state government employees; creating a thriving ecosystem for blockchain by involving both entrepreneurs and communities.

    This page policy details the crucial areas where blockchain technology can significantly benefit the country. The paper also spoke of upskilling and training in blockchain technology. Based on the worldwide evaluation, the total number of blockchain developers is up to 10, against 10 million Java developers, which NITI Aayog recognised both as a challenge and an opportunity.

    Having noted this, NITI Aayog said that the existing programming community could be upskilled to blockchain programming. After a strenuous six-month testing and trial period, China rolled out the much anticipated Blockchain Service Network BSN for businesses. With this, organisations and programmers will be able to build blockchain-based applications seamlessly.

    BSN is a unified platform for blockchain programmers to connect and code using private blockchain protocols and public chains. The main objective of BSN is to reduce operational costs, improve adaptability, and provide better administrative oversight.

    Also, decide if the application needs to be developed on a permissioned or permissionless blockchain network.

    It would help if you also decided on front-end programming languages to be used, servers, and external databases in this stage. A proof of concept is done to represent the practical applicability of a blockchain project. It can be either a design prototype or a theoretical build-up. In Theoretical Build-up, each project requires theoretical cases so that users could understand the applicability and viability of the product.

    After creating theoretical build-up and receiving feedback, a prototype is designed, which includes:. When the client approves the PoC, the next step is to prepare technical and visual designs for the application. Since you have planned an entire application at this stage, start creating UIs for each software component.

    Designs APIs that will be integrated with user interfaces to run an application at the back-end. Once the admin consoles and user interfaces are designed, the application gets ready for development. Development is the significant phase of the blockchain development process, where you should be ready to build the blockchain app.

    In this specific stage, you either have to develop or integrate APIs for particular use cases of the application. The application is built under multiple versions.

    Once the client approves it, the application moves to the next stage, i. But, the software might not comprise all the features at this stage.

    After the alpha version is released, the app is prepared for the beta version. During Beta Phase, the software application has the complete feature set but with some unknown bugs. Developers share the beta version with a particular group of people outside the organization to test its functionality. Once the beta version is approved and tested, the application moves to the Release Candidate version, which is an advanced beta version that is ready to be a final application and can be launched.

    After thorough testing, the application moves to the production phase and gets ready for delivery. Before an app goes live, you should deploy it on the test network to carefully test its functionalities.

    When deploying an application, administrators can also manage which versions of the app need to be deployed to various resources with provisioning. Once an application is provisioned, it needs to be hosted on the main chain.

    If your blockchain app is a hybrid solution, i. The application should be able to upgrade according to any new business needs and prioritization. For instance, if you need to upgrade the smart contract, later on, you should be able to deploy the new contracts without any difficulty.

    Developing and deploying an app does not mean you are done. Instead, a software application needs to be maintained post-development to ensure that it works with all types of upgrades in the future.

    An Ethereum client, Geth, is used to run Ethereum nodes in the Go programming language. Using Geth, users can mine Ethers, create smart contracts and run them on EVM, explore the block history and send tokens between addresses. Geth can be downloaded and installed on Linux, Windows and Mac. It supports two types of installations, Scripted and Binary.

    Once you start using the Geth, you either have an option to create your own blockchain based on the provided settings or connect to the existing blockchain. Remix IDE is a compiler used for small contracts. It is a browser-based tool used to create and deploy smart contracts. You can use Remix IDE to write, debug, test and deploy smart contracts using the Solidity programming language. Remix can connect to the Ethereum blockchain via Metamask.

    Before using Ethereum, you should have a place to store Ether tokens and execute smart contracts. Mist is the Ethereum wallet used for smart contract deployment and is available for Mac, Windows and Linux. While installing Mist, remember once you set up the password, you cannot update it again. Create a strong password and never forget it. It allows users to make calls to the blockchain without the need to run an Ethereum node.

    GanacheCLI is used for the instant mining of transactions. It is an easy-to-use API that provides you with an overview of test chain events. Security plays a prominent role when it comes to building a blockchain application. You need to ensure that the Solidity code does not have security holes. Solium tool is specifically designed to format solidity code and fix security issues in the code.

    EtherScripter has an easy-to-use interface used for coding basic smart contracts. With a simple drag and drop interface, developers can connect different components as jigsaw puzzle pieces for developing a contract.

    It only supports the Serpent programming language. A development framework for Ethereum-based dApps, Embark, is used to build and deploy dApps and enable you to create smart contracts written in Javascript programming language. If an application contains multiple contracts, Embark can also handle the migration of smart contracts.

    Developers can manage contracts on multiple blockchains such as live network, testnet and private net using the Embark framework. It is a wallet that connects Chrome or Firefox with Ethereum blockchain by acting as a browser extension. It can save keys for Ether and ERC20 tokens.

    It can be installed simply as a Chrome extension. Since blockchain is immutable and transactions once added to it cannot be updated or removed, untested programs can result in high costs. That is why it is essential to test a decentralized application before it is deployed on the mainnet. Ensure to test your app on Blockchain Testnet before going live.

    Truffle is a framework for Ethereum that provides a development environment. The framework supports a library which can link complex Ethereum apps and offer custom deployments to make contracts coding simpler. It supports some of the features mentioned below:. You will find numerous tools that can be used to develop blockchain apps dApps and smart contracts.

What value does Blockchain add to your platform?

    When to use blockchain for your startup or existing platform? How much does it cost to build a blockchain-based platform? What is the blockchain development process? What is the best app development tools? How long blockchain development takes? List of top blockchain development companies. How to develop blockchain from scratch? However, many other options allow us to build blockchain protocols in a short period. Processing Speed Blocks are confirmed rapidly, and transactions are added to the blockchain within 1.

    Self-sustaining Bitshares ensures the blockchain covers costs to keep going with no maturity date, as it is backed by an ecosystem of dApps to self-fund its native token BTS.

    Security It is impossible to hack the Delegated Proof-of-Stake DPoS protocol as it involves taking out many global, active and trusted delegates. More Transparency The history of transactions is becoming more transparent with the implementation of blockchain. Reduced Costs Reducing costs is a priority for most businesses. When to use blockchain for your Startup or existing Platform? Do you want to store data? Is the data dynamic with an auditable history?

    Is the speed of the transaction vital for you? Should a central authority control your data? Do you require a trustless environment? Do you need a little change or no change in rules on the system? How much does it cost to build a blockchain based platform? When estimating the cost to build a blockchain-based platform or application, you need to consider the following scenarios: Developing a blockchain app with an in-house team Hiring freelancers for blockchain app development Hiring blockchain development companies for blockchain app development Here is our analysis of the estimated cost of blockchain development for a minimum viable product when using different development resources.

    The cost of blockchain app development also depends on the following factors: Type of Blockchain App you need The complexity of a Blockchain Project People involved in developing an app Project Management Tools Third-Party Tool Subscription Costs Type of Blockchain App you require Every business requires a digital solution to run their business operations efficiently.

    The complexity of a Blockchain Project The complexity of a blockchain project depends on the issues that an application wants to solve. Project Management Methodology Companies might use agile methodology tools such as Jira, Confluence, and Trello to manage blockchain projects. Third-party Subscription Tools Your blockchain app might require a subscription to third-party subscription tools such as bug tracking tools, notification services, amazon web services, software monitoring services, and data analytics tools.

    What is the Blockchain Development Process? Identify problems you want to solve with blockchain First of all, it is essential to develop a problem statement and understand all of the issues you want to solve with a proposed solution. If one node tries to lie, then its record of the blockchain won't match that of the other nodes, and it will be automatically ignored.

    This system of consensus is fundamental to the security of the blockchain. You control your personal data on a blockchain by using private keys. A private key is like a lengthy password that gives you access to a digital wallet where your personal data is stored. This data could be anything from money to details about your last medical check-up.

    The benefit of a private key is that it doesn't have to be stored on a central server, unlike passwords for regular websites like Google or Facebook, which are prone to hacks. Blockchain encryption and private keys explained. On a trustless network like a blockchain, you can ask for payment from someone you have never met, and when the payment arrives, you can be sure that it is legitimate and verified, all within a matter of minutes. Another issue blockchains solve is the double-spend problem.

    The double-spend problem basically centres around the idea that on a database, someone can make an entry and then go back and change it if they have the power or authority to do so.

    This would essentially allow someone to spend the same money twice. Blockchains belong to a group of technologies known as distributed ledger technologies DLT. DLTs as we know them today have only been around for a decade or so, but are already receiving a lot of attention and development. Much like the Internet, additional protocols and technologies are being built on top of blockchains to further their abilities. No article discussing blockchain technology would be complete without mention of cryptocurrency.

    Cryptocurrencies are digital "coins" that are native to their blockchain and can be used to reward node operators that help to secure the network and verify transactions. Because blockchains require computing power to operate, cryptocurrencies were created as a way of rewarding network participants for their efforts. Cryptocurrencies also double as a store of value. The world's first cryptocurrency, bitcoin, was created in and has since spawned a revolution in digital assets and finance, with over 1, cryptocurrencies now existing today.

    Much like their big brethren cryptocurrencies, tokens are also digital assets that are stored and traded on a blockchain. However, unlike cryptocurrencies, tokens are programmed "on top" of an existing blockchain, allowing them to piggyback the existing network infrastructure in the process.

    This means that tokens can be created easily, can be programmed for an even bigger variety of uses than their underlying cryptocurrencies, and can be used to represent almost anything, including gold, fiat currency and even electricity usage. What is an ERC token? Pioneered by the Ethereum blockchain, smart contracts are digital contracts that you can program to perform a specific set of functions. Like a physical contract, fulfilment of the contract requires that participants meet certain conditions, but unlike a physical contract, smart contracts can then execute the terms automatically once these conditions are met, such as paying out an insurance claim once you have paid the premium.

    Furthermore, smart contracts can do this without the need for middlemen, reducing cost while increasing speed and accuracy. According to financial services company, PwC, smart contracts may even eliminate the need for lawyers. If smart contracts were the second revolution of blockchain technology after cryptocurrencies, the digitisation of real-world assets on the blockchain could be the third.

    The ability to digitally render ownership of a real-world asset on a blockchain has huge implications for transparency, efficiency, ease-of-use and fundraising for traditional securities markets. Blockchain has a wide variety of uses within the emerging Internet of Things.

    For the uninitiated, the Internet of Things refers to the network of Internet-enabled devices, such as smartphones, TVs, cars, consumer appliances, etc. Blockchain is able to assist the way these devices communicate with each other, transact, stay secure and automate processes. For example, distributed ledger platform IOTA is working with several car manufacturers, such as Volkswagen, to integrate microtransactions , which will allow electric vehicles to autonomously charge their batteries as well as pay for parking and tolls.

    A report by financial services firm PwC notes that in regards to blockchain and IoT, "There is huge potential here: in , there were already over 5 billion connected devices; this should rise to 20 billion by Digital identities are nothing new, but blockchain promises to bring existing disparate systems together to create a product that is greater than the sum of its parts. Thanks to the efficiency and privacy of blockchains, governments and organisations could safely record an individual's details on a blockchain, while giving ultimate control of that data to the end user.

    Another advantage is that unlike physical documents, a distributed ledger is immutable and cannot be lost or easily destroyed. While each implementation of digital identities will no doubt vary, several existing uses of blockchain for digital identity demonstrate how it can be used. In Australia, NSW has already begun trials of a digital driver's licence stored on smartphones and secured by a blockchain. As the refugee crisis continues, the World Food Program is using blockchain to manage food vouchers and ensure aid is reaching those who truly need it.

    And industry heavyweight Microsoft began testing a decentralised blockchain ID system in for a broad range of applications. Global supply chains are another industry that blockchain looks set to disrupt in a big way. Giants of industry such as Maersk , Amazon, Walmart and DHL are all exploring ways to improve their existing systems with blockchain technology. Blockchains have the ability to add a level of authenticity and trust to supply chains that is sorely missed by legacy systems.

    Startups such as VeChain , WaltonChain and veteran companies like IBM are all applying blockchain in innovative ways to improve the supply chain industry. Public vs Private blockchains Despite the world's first distributed blockchain being a public affair, several companies have entered the space and found ways to commodify the technology, leading to the creation of permissioned private blockchains.

    Private blockchains differ to public blockchains in that the nodes which operate and secure the network are privately chosen. This means that the network is effectively centralised, due to the ownership of nodes by a single entity or a consortium of private parties.

    Blockchain purists argue that this goes against the fundamental purpose of a blockchain , which is to be decentralised. Because decentralisation is a cornerstone of blockchain security and integrity, the argument is that by centralising all the nodes there is almost no point in running a blockchain.

    Private blockchains, of course, have a place; otherwise, people wouldn't use them. Despite the concerns around centralisation, they are often faster and can process more transactions per second than public blockchains. Furthermore, the organisations using them may have less need for the benefits that a decentralised network confers. For example, the privately operated Red Belly Blockchain can reach speeds of 30, transactions per second, whereas the highly popular public blockchain, Ethereum , currently transacts at a speed of roughly 15 transactions per second, although improvements are planned.

    Public blockchains are also, by their very nature, public. This means that anyone can see the transactions, anyone can join the network and anyone can see the code. Allowing the public to view everything helps ensure compliance, transparency, and security but can also lead to exploitation.

    Furthermore, anyone can host a program on the network, which may cause the network to slow down if it becomes too popular. So as you can see, public and private blockchains each come with their own set of strengths and weaknesses, which again differs depending on the particular blockchain at hand. Therefore companies, developers and users must choose which system they would prefer to run, depending on the task at hand. Anyone can create a blockchain, although certain blockchains are more popular than others.

    Bitcoin was the first public blockchain created, and it was designed for the transfer of wealth without a trusted third party. Since then, many different developers, companies and hobbyists have created their own blockchains for all sorts of purposes. Enterprises are now using those blockchains both public and private to improve the way they do business , often cutting out the need for previously required roles , speeding things up and making business cheaper.

    Let's take a look at some of the biggest companies using or exploring blockchain technology this year. Identifying issues with blockchain technology really depends on where you sit and the particular blockchain. Critiques often revolve around speed, issues of centralisation or decentralisation , adoption, complexity and privacy. Some of these issues have fairly simple solutions, such as choosing a private blockchain to increase privacy or creating a new interface to improve usability.

    However, the one major issue that several of these smaller issues contribute to is the issue of scalability. Scalability refers to the ability or lack thereof for blockchains to scale as more users join the network.

    As more users join, speed and size bandwidth needs to increase in order to process all the new data being added. Currently, blockchains struggle to do this without making a trade off in other areas, namely decentralisation and security. This three-way trade-off among scalability, decentralisation and security has become known as the Blockchain Trilemma.

    The Blockchain Trilemma refers to the existing problem in blockchains where any improvement to scaling, decentralisation or security cannot be made without a detrimental impact on at least one of the other two. Many blockchains have tried to solve the trilemma, only to improve in one area but lose out in another. This is currently one of the biggest issues with blockchain technology, and cited by many as the reason why blockchains have not replaced existing systems like Visa and SWIFT for payments.

    Decentralisation and distributed are actually two different features, but both are important to blockchain security. Decentralisation refers to there being no central authority that can make changes to the blockchain.

    Decentralisation is never a guarantee, but rather something that public blockchains work to ensure. Private blockchains on the other hand may actually choose to be centralised because it suits their needs. Distributed systems refer to the fact that instead of data being stored on a central server, the data is stored across multiple servers, or nodes.

    All blockchains are distributed, which means there is no central point of failure if the network were ever attacked or physically damaged. Since blockchain is a type of technology, you can't invest in "it" per se; however, you can invest in companies or organisations that use it. Cryptocurrencies are a popular form of blockchain investment since they allow people to purchase the currency or token that powers a particular blockchain or uses the blockchain.

    Another way to invest in blockchain is by choosing companies that are developing blockchain technologies and purchasing stock in those companies. James Edwards is a personal finance and cryptocurrency writer for Finder.
