Blockchain: what is it and what does it mean for development?
In fact, many reassessing the advantages ICOs have over more expectations fundraising platforms derive from their unregulated for. Does blockchain really meet a need that is not already being served? From consultation to PoC, visual and technical designs, development, deployment and maintenance, blockchain experts at Development provide end-to-end assistance to startups and enterprises. How to integrate my topics content and my website? I don't have a Facebook or a Twitter account. In the second, policymakers must consider whether to change existing laws to facilitate blockchain use of decentralized models. Education-Evolution 3.
Over the last two years, the largest development organizations have begun to examine how using the technology might help them meet their goals. This includes the World Bank, which established a Blockchain Lab in ; the United Nations, which reports that 15 UN entities are carrying out blockchain initiatives; the Inter-American Development Bank, which is exploring the use of blockchain as a platform for asset registries; and USAID, which recently a published a primer on the topic.
This is all happening as the number of start-ups pitching ideas continues to grow and distributed ledger models continue to evolve. Despite these advances, however, the number of pilot projects underway remains quite small. While this could be just a matter of timing—many of the organizations mentioned above are now reviewing project proposals—it may also reflect hurdles to implementation that have received insufficient attention to date.
Given that blockchain technology is still in an early stage of development, it makes sense that most discussions about its use have focused on its potential rather than obstacles. Too often, however, boosters of the technology have overstated its capabilities and failed to consider obstacles to adoption. This imbalance has led to unrealistic expectations about what blockchain solutions can do, how easy they will be to implement, and how quickly they can scale, if at all.
The result has been a widening gap between expectations and reality that has naturally led to growing skepticism. This brief essay explores a key but often overlooked hurdle to using blockchain solutions, which is the complexity that decentralized solutions necessarily introduce.
At times, the benefits of such solutions appear to exceed the added cost of complexity but often they do not. With this tradeoff in mind, the paper considers two use cases, digital ID and health supply chain management.
Finally, the paper offers recommendations about how the development community can shift the conversation in a more useful direction. The notion that the technology can substitute for trustful relationships is, in most cases, misguided. At best, the technology can enhance trust in some relationships by increasing the transparency and immutability of transactions and records. It is also important to recognize that, while early excitement about blockchain focused on the transformative potential of public, permissionless networks like Bitcoin and Ethereum, interest and investment has shifted strongly towards permissioned ledgers, in which only verified parties can participate.
These closed networks are much more likely to help centralized actors achieve efficiency gains than they are to lead to their displacement.
Yet even when the assumption holds, moving from a centralized to a decentralized solution always comes at the cost of added complexity. This increased complexity can take different forms. At the most basic level, moving from a system in which a single actor verifies who owns what to one in which many actors share this responsibility requires using a consensus protocol, even the most efficient of which adds delay.
While some of these encryption approaches are no more complex than those used by centralized databases, others, like those that rely on zero knowledge proofs, are more computationally intensive. Additional layers of complexity may be required depending on use case. For example, using blockchain as a platform for digital ID raises the question of how individuals manage their private keys.
Perhaps the biggest challenges raised by shifting from centralized to decentralized models relate to legal and regulatory considerations. In the first instance, companies interested in using the technology must determine how they can comply if at all with existing data security and privacy laws. In the second, policymakers must consider whether to change existing laws to facilitate the use of decentralized models.
It is therefore inherently political. Whether the benefits of using a decentralized model exceed the added cost of complexity ultimately depends on the use case in question. In recent years, a variety of decision models have been created to help guide the process of weighing these tradeoffs a recent iteration, this one produced by the U.
Department of Homeland Security, is presented in Figure 1. Below we explore two development use cases through this tradeoffs lens. At the same time, there is growing concern worldwide about the vulnerabilities associated with the storage and use of personal data by governments and companies.
Many believe that both problems could be solved by using a self-sovereign identity SSI approach to ID. Under the generic SSI model, individuals use a digital wallet on a blockchain to store certifications from trusted authorities e. When the user must show that she has certain attributes to service providers e.
Storing verified claims on a blockchain create several potential benefits for users. The first is control: SSI could enable a person to manage both who she shares her personal information with and how much information she shares.
Such a system could also be more convenient, since it could allow people to provide verified information with the touch of a button rather than having to access and submit a wide variety of documents.
Finally, the near-impossibility of tampering with records on a blockchain could provide greater confidence about their authenticity. First, storing ID documents and important records on a blockchain could make it easier for refugees to verify their identity and obtain appropriate services if they relocate e.
Similarly, they could use their digital wallets to store a history of their economic transactions, which would allow them to develop a credit history that could be used to access financing.
While these features are promising, the model also has serious limitations. In addition, the portability of IDs generated and stored on a blockchain depends entirely on how many organizations either on or off the network are willing accept them. For that reason, getting multiple governments and development organizations to agree on a single SSI approach is a prerequisite to developing an effective model. The SSI model also introduces complexities that may make it difficult to scale.
This includes challenges related to key management. The World Health Organization estimates that one in ten medical products used in low- and middle-income countries is either substandard or falsified SF , with most reported cases 42 percent coming from Africa.
Interest in improving health supply chains is not limited to developing countries. The US Drug Supply Chain Security Act passed in calls for the development of an electronic, interoperable system to identify and trace the movement of prescription drugs distributed in the country by The European Union passed similar legislation in Both initiatives have spurred investment in possible solutions, including blockchain.
Over the last year, several initiatives that aim to use blockchain to meet track and trace regulations have been announced, including The MediLedger Project and a collaboration between DHL and Accenture. The idea of using blockchain technology as a platform for supply chains holds great promise. By providing a single, tamper-resistant ledger on which transactions can be viewed by all actors with appropriate permissions, the technology could reduce many of the frictions and vulnerabilities in existing supply chain networks.
However, you should take this path if software development is your core business. On the other hand, hiring freelance blockchain developers could be less expensive but very risky. Working with a third-party company could be a viable option if your project is enormous. Blockchain companies are experienced and can help you at every step of the development process. When compared to an in-house development team, the cost of blockchain companies is lower.
Every business requires a digital solution to run their business operations efficiently. Building a blockchain app can build trust and offer transparency while removing additional intermediaries. Before implementing blockchain technology and estimating its cost, it is essential to understand the type of blockchain app you need. Whether you need a permissioned blockchain app or a permissionless blockchain app, you need to consider which application can suit your business needs.
Also, the cost of a blockchain application varies from industry to industry. For example, you may need an app for supply chain management, healthcare, real estate, education, and many other business domains.
The cost of an app will depend on the complexity of the project. The cost of blockchain app development also depends on the number of resources required to develop an application. Salaries of blockchain experts are the significant expenses you should not miss when calculating the cost to build an app. While investing in blockchain developers, ensure you have hired the best ones and added their salaries to the total expense.
Companies might use agile methodology tools such as Jira, Confluence, and Trello to manage blockchain projects. They use such tools to test an app, track timelines, and deliverables. Therefore, the price of project management tools is also added to the cost of blockchain implementation. 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.
The cost of subscription tools also contributes to the cost of blockchain app development. In this section, we have explained the process of building a blockchain-based application. 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.
Ensure that the blockchain solution will benefit your business abilities. Analyze whether you need to migrate your current solution to the blockchain, or you require a new application to be developed from scratch. For example, suppose you are a healthcare provider who wants to develop a blockchain-based health record exchange app. In that case, you should know various use cases of the applications and what benefits it will offer to users.
Once you decide that you need a blockchain solution for your business operations, the next step is to select the right blockchain platform and blockchain development tools for your project.
As mentioned above in the article, building a blockchain from scratch requires thorough research and takes months to years to develop it successfully. Therefore, you should build a blockchain app on top of a blockchain platform that meets your business requirements.
You should identify the right blockchain platform for your application based on the factors like consensus mechanism and problems you want to solve. For example, you can build an Ethereum-based application to develop a decentralized public application with smart contracts. When the blockchain platform is identified, you must do brainstorming and understand the exact business needs. Once you identify the blockchain platform for developing a blockchain application, you should focus on drafting business requirements and brainstorming ideas.
Find what technology components should be added as off-chain or on-chain entities on the blockchain ecosystem. Create a roadmap of the product that will help you to build an application within a decided deadline. You should come up with a blockchain model and conceptual workflow of the blockchain application. 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. To know which is the best blockchain development tool for your project, consult our team of blockchain experts.
The project is initiated with PoC, which typically takes weeks. Once the PoC is done, it takes weeks to develop a minimum viable product with bare minimum features. Launching an application on the mainnet takes around months based on the requirements of a client.

Each block contains the hash of the block before it, which links the two and forms the chain. When a transaction takes place, its details are encrypted and a unique multiple-character transaction number is generated. Instead of other users in the blockchain being able to see the exact details of the transaction, this number is recorded in the ledger as a placeholder. All the users of the network will be able to see that the transaction has taken place but only the parties involved in the transaction can access and view its details.
All this makes any fraudulent activity easier to spot. An external hacker would have to gain access to every computer that holds a copy of the blockchain database, and at the same time, in order to tamper with it. Blockchain technology has been around for a number of years and its most well-known use so far is Bitcoin , the virtual currency that came to prominence in The uses of blockchain are not limited to financial transactions, though, and enthusiasts are looking into other ways applications for the technology, especially for the types of transactions where there are often disputes or trust issues, such as with land rights.
As an emerging technology, blockchain enthusiasts are hopeful it could be the next big development disruptor. In providing a transparent, instantaneous and indisputable record of transactions, its potential to remove corruption and provide transparency and accountability is one area of intrigue. But there are still many questions around how to apply the technology.
Does blockchain really meet a need that is not already being served? And is there a market where it serves a purpose? Towards the end of last year, the Start Network announced a project to trial how blockchain technology can speed up the distribution of aid funding and trace how it is spent.
