Cryptocurrency Development provides excellent multi cryptocurrency wallet Development techniques. Looking to Launch your ICO? Blockchain Development With Quest Global Technologies you can find a find a perfect blockchain application solution for different industries to build fast, unique and secure identity for your business. Start a Project. Firstly, did the lottery winner choose a wait time randomly? Else, a member could intentionally choose a shorter time to win the leadership.
It is the crucial stage of blockchain development process as the entire project depends on the platform you are going to choose. After choosing the blockchain platform based on their consensus mechanism, the next step is to undergo a blockchain ideation process to analyze the technical components and the roadmap for the product.
Once you have identified the problem and blockchain platform to build the application, it is the right time to brainstorm ideas and business requirements. In this step of the blockchain development process, you need to evaluate, formulate, and prioritize use cases for blockchain experimentation. Decide what components should be added as on-chain and off-chain business entities. Prepare a roadmap of the product, i.
The primary deliverable of the blockchain ideation is to design a conceptual workflow and blockchain model of the application. Decide if the application needs to be built within the permissioned network or permissionless network. While formulating ideas, you also have to make decisions related to the front-end programming language, external database, and servers for your application.
After developing the ideas, you should prepare a proof-of-concept to reveal viability of the product. A proof-of-concept is a way to demonstrate the practical potential of a blockchain project and it can either be a theoretical build-up or a prototype.
Every project needs theoretical cases so that the end-users can understand the viability and productivity of the product. Create proposals to explain the parameters of the project. After completing the theoretical build-up and receiving feedback from every involved stakeholder, you should come up with a prototype containing sketches, information architecture, mockups, designs, and tested product.
Once the stakeholders approve the PoC, start focusing on preparing the visual and technical designs for the application. Now that you have planned everything, start creating user interfaces for every component of the software. Also, design APIs you need to integrate with user interfaces to run the application at the back-end.
While preparing the visual and technical design, it is also essential to document the technical GDPR compliance requirement to understand in which components it should be applied. GDPR has become a crucial part of the design process which should never be ignored.
After designing the user-interfaces and admin console for the application, you are ready for the development process. Development is the core stage of the blockchain development process where you should be prepared for building the application. In this particular stage, you are required to build APIs for distinct use cases of the application.
But do you know why do we need APIs? The application is developed under different phases. First of all, the application developed that does not undergo formal testing is said to be in pre-alpha phase. Then, the application jumps to the next stage, i. After the alpha release of an application, it is prepared for the beta release.
During Beta Phase, the software contains the complete feature set, but it might have unknown bugs. Once the beta version is ready, the application gets prepared for Release Candidate version. A release candidate is an advanced beta version which is now ready to be a final product. When the application is tested thoroughly, it is moved to the production phase to get ready to be delivered.
Deployment is the process of putting an application onto a prepared application server. Before an app goes live, it should be deployed on the test network to test its functionalities.
While deploying an application, administrators can also control which versions of the app should be deployed to different resources using provisioning. After provisioning an application, it should be hosted on the main chain.
For example, if you have built an application on the public blockchain, it should be released on the main network. If your application has both off-chain and on-chain business entities, i.

For example, a scientific information blockchain system is proposed to lower the costs at scientific information access and make it open and universal. The intention is to make larger parts of the research cycle open to self-correction [ 13 ]. A global higher education credit blockchain platform is proposed to constitute a globally trusted, decentralized higher education credit, and grading system that can offer a globally unified viewpoint for students and higher education institutions, as well as for other potential stakeholders [ 14 ].
A digital identity blockchain ecosystem is developed to create secure and trusted digital identities to reduce identity theft and improve public safety, which allows citizens to carry out high-value and daily transactions online [ 15 ]. The existing credit systems are not well recognized because of separate brokerage systems, non-pertinence, centralized and static evaluation models, and insufficient supporting information. The authors have been developing creditworthiness-related projects since and proposed an autonomous credit system to exploit potential feasibility and performance that the blockchain and smart contracts may make for online trading [ 16 ].
The autonomous blockchain system is envisioned as the next generation of credit system in that it is trading-oriented and to match all the trading-related participants. It is developed to be an integrated, traceable, dynamic, and personalized blockchain ecosystem. The goal is to make the participants and transactions credible besides credible data in a blockchain system. It, therefore, supports creditworthy business commitments, with life-cycle and multimedia tracing information while no dependency on any credit brokerages.
The pioneer blockchain project, cryptocurrency Bitcoin, is surrounded by numerous skeptics as most of the deviated cryptocurrency projects have failed except those forked from Bitcoin. A large portion of blockchain applications have been aborted, and there is not yet any blockchain project found successful to its efficiency at other application scenario.
However, blockchain-raised magic ideas are so attractive that people would never give up. Numerous researches have been conducted to improve or innovate its core techniques or discover feasible and efficient use scenarios around the world. The underdeveloped techniques are objective to address the critical issues that block the acceptance and development of blockchain systems.
The blockchains are secure but not creditworthy. The devoted credit mechanisms are required to make blockchain systems to be creditworthy although blockchains provide a creditworthy infrastructure for data-level storage and operations. An autonomous credit system is proposed by the author [ 16 ]. It is trading-oriented to satisfy all the involved trading participants. A blockchain creditworthiness ecosystem is developed to implement the credit system as it provides an open, equal, and creditworthy infrastructure.
And it is through a collection of smart contracts that all the blockchain operations are processed. A creditworthiness model is developed to implement the credit system to make it more integrated, traceable, dynamic, and personalized. Several pilot projects have been developed to test the feasibility and efficiency of the proposed autonomous credit system.
Four creditworthiness clouds have been developed as public blockchain clients and creditworthiness query services. Networking models of blockchain. Four types of blockchain networks have been identified, including public blockchains, private blockchains, consortium blockchains and hybrid blockchains.
Public blockchains are difficult to be feasible, while private blockchains do not manifest their technical potentials. Most of the ongoing projects use consortium or hybrid blockchains, which take some centralized mechanisms and some decentralized mechanisms [ 17 ]. For now, what features from Bitcoin are fundamental for blockchains and what are optional or changeable is always a popular argument and not yet got concluded. For example, should a blockchain system be supervised or not?
New methods are required to develop audit plans that identify threats and risks [ 20 ]. With boosting blockchain ventures, application-driven blockchain techniques have been developed to meet particular business features, and a variety of business-level techniques for blockchain-based applications have been delivered.
The business-level techniques further boost and improve the fundamental blockchain techniques to make complete system solutions to the blockchain applications.
In a joint project in which the authors have a part, it is for an autonomous creditworthy trading ecosystem that all layers of the blockchain techniques are research subjects and developed. To support efficient and complicate trading scenarios, the blockchain infrastructure is improved to explore interconnected blockchain networks with multi-layer and primary-secondary relationships, to define product-oriented block data structure, to replace the blockchain-layer proof-of-work with business-layer incentives, and to develop blockchain gateways and internetwork consensus mechanisms to connect multiple blockchain networks.
For unmanned trading, smart contracts techniques for secure verification and interactive models are to be developed. Further special data processing techniques are developed to integrate data from outside and inside the blockchains, and address the data scarcity and insufficiency raised by self-regulated blockchain data. There are several critical issues to be addressed to implement a feasible and efficient blockchain application ecosystem.
From the view of a software system, a typical blockchain ecosystem has four layers, including the blockchain, smart contracts, services, and user interfaces. The critical implementation issues for an ecosystem are to design network model, ecosystem architecture, participants and admission policies, nodes and polling mechanism, incentive mechanism, smart contracts, and clients.
Furthermore, data collection and data processing algorithms are required to address the critical issues with blockchain applications. The blockchain network model is a challenge for most of the current projects. The blockchain techniques are fast evolving, and no well-accepted technical specification has been released. Some projects following Bitcoin have not got acknowledged due to their in-efficiency and performance cost.
Some only take blockchain as a distributed database infrastructure. More projects are designed with self-designed hybrid networks or variation network models. Among them, the blockchain provides a decentralized and self-regulating data infrastructure in which all data and transactions are stored.
Participants should be identified based on the blockchain network and their role. The number of nodes and evolvement policies are defined based on the polling mechanism and operation objectives. In the case of consortium blockchains, the admission policies and required information are designed based on the network model. A reasonable and efficient incentive mechanism should be developed to make the blockchain prevailing, and design an efficient consensus mechanism.
Smart contracts are well accepted as the greatest enabling technology for blockchains. With them a blockchain ecosystem becomes autonomous, open, consent, and credible. It is through a collection of smart contracts that the blockchains can operate without human intervention. The smart contracts are developed to deploy at the predefined blockchain nodes.
Generally, both the blockchain operations and application-related rules can be programmed as smart contracts. Blockchain clients for participants. There are three types of blockchain clients, which interact with the blockchain ecosystem through application programming interfaces.
The second type of clients are smart contracts or those provided by the blockchain operation system, such as the blockchain browsers. The third type of clients are public facilities by the blockchain, which provides a public user interface for both the participants and potential participants.
Data collection techniques are critical to support blockchain-based businesses. It is considered that the data are private and self-regulated by the participants in a blockchain, which raises several popular issues at collecting data; among them are data insufficiency, data scarcity, and data redundancy. It is necessary to develop well-defined compensation algorithms for missing data, attributes, and irrelevant or redundant data.
At the same time, cross-checking and weighting algorithms should be developed to exploit the integrated participation information from inside and outside the blockchain, on blockchain and off blockchain, which could be developed as smart contracts to collect the integrated information. There are further some other concerns to be considered when processing the data. For example, it is required to address how to use the data from other blockchain ecosystems.
After all, the ecosystem is developed to integrate inside and outside of the blockchain, and the requester may come from the other blockchain ecosystem. There are tens of general-purpose blockchain development environments released as open sources. The Bitcoin Blockchain is the first player from , with the new concepts of Bitcoin, miner, proof-of-work, transaction, and permissionless [ 21 ].
The Ethereum Blockchain is derived from Bitcoin and prevails since its beginning, with which the concepts are Ether, Ethereumminer, proof of stake, account, permissionless [ 22 ]. Hyperledger Blockchain has been developed for business. Hundreds of blockchain development environments have been developed for special applications or scenarios such as supply chain finance, financial clearance, business regulation and supervision.
They have been improved with improved infrastructure, consensus mechanisms and design patterns to get higher performance and best-fit special scenarios on the general-purpose blockchain development environments. For instance, a permissioned blockchain, called Beihangchain, has been developed with its unique consensus algorithms, interfaces, and design.
The blockchain used an account blockchain and a trading blockchain for a variety of applications including copyright protection and digital payment [ 24 ]. The Hyperchain is a self-contained and controllable blockchain platform that provides enterprise-level blockchain network solutions. It enables the enterprises to deploy, expand, and manage blockchain network based on existing cloud platforms, and provides real-time visual monitoring of its operation status [ 25 ].
The basic mission of blockchains is to establish a creditworthy ecosystem among independent participants in a non-trustable distributed environment. Very few of the blockchain ventures are necessary, feasible, efficient and survive. Despite low successful cases, with its magic attraction, the blockchain technologies and application scenarios are continuously being innovated and improved. Another period of blockchain prosperity is on its way since the two symbolic projects, the Libra by Facebook and the DCEP by Central Bank of China, were announced to be launched.
To embrace the booming blockchain time, this article provides some insights into blockchain applications and techniques. The advances and possible innovations and researches on blockchain applications and techniques are presented.

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.

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.

Enterprise Blockchain Development Blockchain has huge potential to transform many businesses like Banks, Financial services, Healthcare, Real Estate, Supply chain, etc. The participants of the ecosystem are peer entities with equal privileges to each other.
The data of the ecosystem records are private and self-regulated to decide which participants can receive and view. There are tens of thousands of blockchain-based application systems have been developed for smart contracts, notarization, asset trading, bank clearance, ecommerce, social communication, Internet of Things, storage, data API, finance, to provide data-level, business-level, or service-level infrastructure.
Many of them are shut down in a few years due to low necessity, feasibility or performance along with business operation issues. There are several basic concerns to be addressed when evaluating a blockchain venture, as shown by Fig.
Why is it necessary? How many benefits are expectable for the participants? What about its performance? Is it operable to start up? Furthermore, what are the innovations by introducing blockchains? It is the cryptocurrency Bitcoin that brings acceptance and prosperity of the blockchain-based technologies, as the blockchains provide secure, open, and decentralized transaction infrastructure for Bitcoin. Since then, thousands of Bitcoin-like or Bitcoin-derived projects have been launched.
Most of the blockchain concepts are developed from the Bitcoin blockchain, and cryptocurrency and payment ventures are still emerging to be the most popular application areas, despite the fact that very few of them survive and Bitcoin is illegal in some countries.
The two projects are ambitious to provide anonymous digital wallets with no bank account, and make new electronic payment infrastructure across the world. The Libra is announced as a stable currency built on a secure and stable open-source blockchain, backed by a reserve of real assets, and governed by an independent association [ 4 ].
The two grand visions are destined to make tremendous impacts on transnational financial systems and international politics. Compared with the autonomous Bitcoin system, the two projects have been developed with tremendous resources and by most powerful groups either in America or China.
The blockchain technology is best fit for reliable activity tracking. A blockchain-based application in the healthcare sector was proposed to reduce prescription drug fraud, integrate the medical information, and connect the dental industry. The blockchain is used to solve the problems that medical information is frequently held by individual providers or private data collectors without full patient access.
The authors believe blockchains can make an effective and trustable tracking of transactional information at each step of a process in a transparent and immutable way [ 6 ]. Several commercial blockchain IoT solutions have been put into the market. Within an IoT construct, blockchain can build a trusted and efficient business network based on shared ledger, reduce cost of creating, maintaining and enforcing contracts based on smart contract, produce a permanent or indelible record based on IoT device data, and accelerate transactions through IoT events to trigger smart contract execution directly [ 7 ].
Furthermore, it is popular to use the blockchains to make anti-counterfeit solutions in that authenticity of products is verified by the blockchain network consisting of all market participants in electronic commerce producers, merchants, and marketplaces [ 9 ].
The supply chain is one of the best-fit areas for blockchains as there are multiple entities in a supply chain and need a creditworthy mechanism to cooperate for a business. The blockchain ecosystem can be developed to provide secure, creditworthy, and complete information among the supply chain members to avoid cheating or commercial abusing. The creditworthy data are helpful for small and medium enterprises to get financial services, which is a painful issue with traditional industries.
Also the author learns from some interviews and cooperative projects with industry partners that a number of blockchain projects have been underdeveloped in China to increase the efficiency of finance audit and solve the financial issues of the small enterprises. As illustrated by Fig. Several finance blockchain projects for supply chain can be found at information websites [ 10 ].
Further, with smart contracts, blockchains have the potential to make more secure and trustable trades or collaborative business among a supply chain. Smart contracts can be used to compose the entire transaction process and automatically executed in a cost-effective, transparent, and secure manner [ 11 ].
For example, a blockchain-based production credit mechanism PCM for manufacturing services is put forward to regulate the cross-enterprise collaborations among socialized manufacturing resources [ 12 ]. The blockchains are supposed to be applicable at many business areas though most of the ventures have failed as mentioned above.
A feasible application scenario is the key for a feasible blockchain application. The scenario should be elaborated to explore the unique blockchain features, and follow invented business rules within the evolved instead of the conventional business environments. It is encouraging that numerous attempts and ventures are under development around the world.
On the blockchain-related information websites, you may find thousands of blockchain projects for tens of application areas [ 10 ]. Also, some blockchain attempts in can be found in the literature. For example, a scientific information blockchain system is proposed to lower the costs at scientific information access and make it open and universal. The intention is to make larger parts of the research cycle open to self-correction [ 13 ].
A global higher education credit blockchain platform is proposed to constitute a globally trusted, decentralized higher education credit, and grading system that can offer a globally unified viewpoint for students and higher education institutions, as well as for other potential stakeholders [ 14 ].
A digital identity blockchain ecosystem is developed to create secure and trusted digital identities to reduce identity theft and improve public safety, which allows citizens to carry out high-value and daily transactions online [ 15 ].
The existing credit systems are not well recognized because of separate brokerage systems, non-pertinence, centralized and static evaluation models, and insufficient supporting information. The authors have been developing creditworthiness-related projects since and proposed an autonomous credit system to exploit potential feasibility and performance that the blockchain and smart contracts may make for online trading [ 16 ].
The autonomous blockchain system is envisioned as the next generation of credit system in that it is trading-oriented and to match all the trading-related participants.
It is developed to be an integrated, traceable, dynamic, and personalized blockchain ecosystem. The goal is to make the participants and transactions credible besides credible data in a blockchain system. It, therefore, supports creditworthy business commitments, with life-cycle and multimedia tracing information while no dependency on any credit brokerages.
The pioneer blockchain project, cryptocurrency Bitcoin, is surrounded by numerous skeptics as most of the deviated cryptocurrency projects have failed except those forked from Bitcoin. A large portion of blockchain applications have been aborted, and there is not yet any blockchain project found successful to its efficiency at other application scenario. However, blockchain-raised magic ideas are so attractive that people would never give up.
Numerous researches have been conducted to improve or innovate its core techniques or discover feasible and efficient use scenarios around the world. The underdeveloped techniques are objective to address the critical issues that block the acceptance and development of blockchain systems. The blockchains are secure but not creditworthy.
The devoted credit mechanisms are required to make blockchain systems to be creditworthy although blockchains provide a creditworthy infrastructure for data-level storage and operations.
An autonomous credit system is proposed by the author [ 16 ]. It is trading-oriented to satisfy all the involved trading participants.
A blockchain creditworthiness ecosystem is developed to implement the credit system as it provides an open, equal, and creditworthy infrastructure. And it is through a collection of smart contracts that all the blockchain operations are processed.
A creditworthiness model is developed to implement the credit system to make it more integrated, traceable, dynamic, and personalized. Several pilot projects have been developed to test the feasibility and efficiency of the proposed autonomous credit system. Four creditworthiness clouds have been developed as public blockchain clients and creditworthiness query services. Networking models of blockchain. Four types of blockchain networks have been identified, including public blockchains, private blockchains, consortium blockchains and hybrid blockchains.
Public blockchains are difficult to be feasible, while private blockchains do not manifest their technical potentials. Most of the ongoing projects use consortium or hybrid blockchains, which take some centralized mechanisms and some decentralized mechanisms [ 17 ]. For now, what features from Bitcoin are fundamental for blockchains and what are optional or changeable is always a popular argument and not yet got concluded. Discover how blockchain technology—including Ethereum networks—works to secure your data and digitise your workflows in these illustrated architectural scenarios.
Businesses use blockchain to digitize workflows they share with other organizations, such as moving physical assets across supply chains. The anatomy of blockchain apps is similar across use cases. A common blockchain pattern is IoT-enabled monitoring of an asset as it moves along a multi-party supply chain. A great example of this pattern is the refrigerated transportation of perishable goods like food or pharmaceuticals where certain compliance rules must be met throughout the duration of the transportation process.

Nasdaq brings blockchain technology to capital markets to manage transaction delivery, payment and settlement from multiple blockchains and payment mechanisms. Microsoft uses blockchain solutions to compute royalty statements for Xbox game publishers in hours, instead of months.
Blockchain is a record-keeping and contract-enforcement technology that is based on complex cryptography. It allows organisations to streamline shared workstreams—such as supply chains—by exchanging and tracking assets and transactions on a shared ledger often called distributed ledger technology or DLT.
Each partner also has the ability to reject incorrect transactions before they are applied to the ledger, which simplifies auditing and greatly reduces the risk of fraud.
In addition to supply chain and shared workstream applications, developers are driving new revenue streams by creating blockchain-based products and services. A "block" is a cluster of data within the blockchain that has both a unique identifier and a history. Blockchain is a transparent and verifiable system.

Describe Service. It is through a collection of smart contracts that the blockchains can operate without human intervention. The smart contracts are developed to deploy at the predefined blockchain nodes. Generally, both the blockchain operations and application-related rules can be programmed as smart contracts. Blockchain clients for participants. There are three types of blockchain clients, which interact with the blockchain ecosystem through application programming interfaces.
The second type of clients are smart contracts or those provided by the blockchain operation system, such as the blockchain browsers. The third type of clients are public facilities by the blockchain, which provides a public user interface for both the participants and potential participants.
Data collection techniques are critical to support blockchain-based businesses. It is considered that the data are private and self-regulated by the participants in a blockchain, which raises several popular issues at collecting data; among them are data insufficiency, data scarcity, and data redundancy.
It is necessary to develop well-defined compensation algorithms for missing data, attributes, and irrelevant or redundant data. At the same time, cross-checking and weighting algorithms should be developed to exploit the integrated participation information from inside and outside the blockchain, on blockchain and off blockchain, which could be developed as smart contracts to collect the integrated information.
There are further some other concerns to be considered when processing the data. For example, it is required to address how to use the data from other blockchain ecosystems. After all, the ecosystem is developed to integrate inside and outside of the blockchain, and the requester may come from the other blockchain ecosystem. There are tens of general-purpose blockchain development environments released as open sources.
The Bitcoin Blockchain is the first player from , with the new concepts of Bitcoin, miner, proof-of-work, transaction, and permissionless [ 21 ]. The Ethereum Blockchain is derived from Bitcoin and prevails since its beginning, with which the concepts are Ether, Ethereumminer, proof of stake, account, permissionless [ 22 ].
Hyperledger Blockchain has been developed for business. Hundreds of blockchain development environments have been developed for special applications or scenarios such as supply chain finance, financial clearance, business regulation and supervision. They have been improved with improved infrastructure, consensus mechanisms and design patterns to get higher performance and best-fit special scenarios on the general-purpose blockchain development environments. For instance, a permissioned blockchain, called Beihangchain, has been developed with its unique consensus algorithms, interfaces, and design.
The blockchain used an account blockchain and a trading blockchain for a variety of applications including copyright protection and digital payment [ 24 ]. The Hyperchain is a self-contained and controllable blockchain platform that provides enterprise-level blockchain network solutions.
It enables the enterprises to deploy, expand, and manage blockchain network based on existing cloud platforms, and provides real-time visual monitoring of its operation status [ 25 ]. The basic mission of blockchains is to establish a creditworthy ecosystem among independent participants in a non-trustable distributed environment.
Very few of the blockchain ventures are necessary, feasible, efficient and survive. Despite low successful cases, with its magic attraction, the blockchain technologies and application scenarios are continuously being innovated and improved. Another period of blockchain prosperity is on its way since the two symbolic projects, the Libra by Facebook and the DCEP by Central Bank of China, were announced to be launched.
