    One of our lead engineers once said that one of the most difficult problems that his team faces blockchain the lack best resources available. The VSCode extension comes with a tutorial gallery that is easy to follow and focused on manipulating the blockchain with smart contracts. Geth is an implementation blockchain an Resources node resources the Go programming language. Developer the moment, processing large amounts of data over the Ethereum network would be hugely inefficient as it developer both slow and expensive. Ganache is another tool from best Truffle suite.

    And for existing use cases, the supply chain space provides by far the most popular and successful use cases. Another helpful resource is the IBM Developer code patterns for blockchain , which offer ready-to-use open source code that developers can use out of the box.

    Blockchain technology is still relatively new and many dev teams may not feel comfortable working with it unless they have considerable experience. Once a dev team has achieved success in one business area, such as coffee supply chain, they will often find a number of clones popping up that adopt existing solutions to new and similar business areas, such as coffee in different geographical areas.

    Since many blockchain apps are open source, especially those that use different dialects of Hyperledger such as Hyperledger Fabric, a recommended first step for a newly minted dev team is to clone an existing blockchain app and apply it to a slightly new domain. Here, blockchain apps in the coffee supply chain provide a good starting point. And speaking of our blockchain development team — what should it look like? The team should include:.

    This makes for a total of about six developers to start with — a number that may well grow as the project grows. Funding is outside the scope of this article. As I mentioned earlier, the best way for a dev team to quickly come up to speed on these concepts is to re-implement an existing open source project such as the Blockchain Bean or another successful open source Hyperledger Fabric project.

    There are many platforms and development tools for creating blockchain applications. This article focuses on the following three:. It is intended as a foundation for developing blockchain applications or solutions with a modular architecture. Hyperledger Fabric allows components to be plug-and-play. Its modular and versatile design satisfies a broad range of industry use cases, and it offers a unique approach to consensus that enables performance at scale while preserving privacy.

    In addition, Hyperledger Fabric comes with superb documentation. Visual Studio Code with Blockchain VSCode extension helps developers create, test, and debug smart contracts, connect to Hyperledger Fabric environments, and build applications that transact on your blockchain network.

    After deciding on a use case, the dev team uses Hyperledger Fabric with the VS Code extension to create a blockchain application with smart contracts. The VSCode extension comes with a tutorial gallery that is easy to follow and focused on manipulating the blockchain with smart contracts. We use the VS Code extension to create, package, install, instantiate, and submit and evaluate smart contracts.

    The VSCode extension tutorial gallery is the obvious place to start learning how to create blockchain applications with smart contracts in Hyperledger Fabric and IBM Blockchain Platform. IBM Blockchain Platform is a cloud-based platform for creating and running blockchain enterprise applications on the infrastructure of your choice. Although most dev teams start their development journey with Hyperledger Fabric or some other favor of Hyperledger, they will almost certainly end up deploying their apps in the cloud, either on a public cloud or in multiple clouds in different configurations.

    Once they have identified a well-documented use case, the dev team then focuses on architecting a business network. I mentioned ledgers in the section 3 above. Business ledgers have been around for a very long time, as a way to manage business transactions. But traditional ledgers have always come with the need to reconcile the ledgers of each business participant with that of all others in the business network — which can be both laborious and error prone.

    Doing away with reconciliation by forcing all members in a business network to use the same shared ledger is a historic innovation. Discarding reconciliation also means that consensus takes pride of place in the business network. All members in the network have to agree before any transactions can be placed on the ledger. However, for the dev team it is not just a matter of plugging in a blockchain and starting to run.

    They must start by determining what data does and does not belong on the blockchain. For example, it is simply not feasible to put gigabytes or terabytes of data on a blockchain if you want to be able to do rapid searches — and searches are one of the must-have features that a blockchain provides. Mist , is the official Ethereum wallet that has been developed by the people responsible for Ethereum themselves.

    While it makes a lot of sense to use Mist, especially for smart contract deployment, you must keep one thing in mind. Mist is available for Windows both and bit , Mac, and Linux and bit. After you are done installing Mist, you will be told to wait for some time as the software syncs you up to date with the Ethereum blockchain.

    Once the node is fully synced, you will be given the option to operate on the test blockchain or the main blockchain. If you simply want to test out Ethereum then we recommend that you use the test blockchain. It is around this time that you will be asked to choose a password. Couple of things that you must keep in mind here:. Image Credit: Karl. Solidity is pretty much your bread and butter as far as developing on Ethereum is concerned. Solidity is a purposefully slimmed down, loosely-typed language with a syntax very similar to ECMAScript Javascript that is used for the creation of smart contracts on the Ethereum blockchain.

    However, something is needed to convert the solidity script to a format that can be easily read by the Ethereum Virtual Machine. Even though technically speaking, they are pretty much built from the same source code, in practice, they tend to come up with slightly different results.

    They also have different command line interfaces. Having said that, solc-js is a little bit slower than solc. A good number of Ethereum nodes natively includes a solc implementation, but it is also packaged as a standalone module for an offline compiling. So, you can decide to use web3. A solidity compiler which has been built of JavaScrip t allows for some interesting applications. One of those applications happens to be Remix, which is our next tool.

    Remix is a great compiler that we use for small contracts. If you are looking to learn solidity then this is seriously the best way to go about it. Simply go to their website and you should be greeted with the following screen:.

    The Remix default screen. You see a screen on the left that lets you write code. The right-hand side lets you deploy your code on the blockchain and lets you interact with the functions that you have written.

    Written in Javascript, Remix supports both usages in the browser or locally. Remix also supports testing, debugging and deploying of smart contracts and much more.

    Remix connects to the Ethereum blockchain through Metamask more on this in a bit. When you are writing programs for the Ethereum Virtual Machine EVM there are certain things that you will need to consider:. This is the reason why you might want to test out the dapp in a testnet before actually using the mainnet to deploy them. Public testnets are freely available to everyone who is connected to the internet. The public testnets available are Ropsten, Rinkeby, and Kovan.

    Instead of a public blockchain, you also have the option to get your own personal blockchain i. So, how exactly do you build this personal blockchain? A genesis file, which gets generated by you, will use a tool, quite like Geth, which will build a new chain just for you. Blockchain teams which are working on sensitive projects and need simulate mining and transaction confirmations without exposing themselves to the risks of attacks and hacks can use these testnets.

    These private testnets are free to create. The only costs that are required are as follows:. Also, once a private testnet has grown enough, the developers involved can expose the network to the public online. It simulates the Ethereum network on a single computer and allows you to make calls to the blockchain without any of the hassles of running a real Ethereum node.

    Over the last years, it has become one of the most widely used exchange in the world. This system enables a wide range of capabilities from gathering read-only data to building something really new. Also, , buy, sell, send and receive bitcoins worldwide, and they offer several client libraries and mobile SDKs that are quite useful for a developer. Along with all this, Coinbase provides a simple and powerful REST API to integrate bitcoin , bitcoin cash , litecoin and ethereum payments into your business or application.

    For example, it is simply not feasible to put gigabytes or terabytes of data on a blockchain if you want to be able to do rapid searches — and searches are one of the must-have features that a blockchain provides.

    Also, some data may already exist in efficient, tailor-made databases that need not be ripped and replaced. Rather than have the blockchain grind to a halt, it is better to keep key data on the blockchain with links to off-chain data as needed.

    The off-chain concept is key for developing successful blockchain applications. This means that your blockchain app is part of existing applications that do not need to be ripped and replaced unless absolutely necessary. A key advantage that blockchain provides is the ability to search the chain of blocks and quickly find key data — something that is impossible with the paper records that are still, amazingly enough, often being used in many traditional ledgers.

    Many blockchain solutions allow businesses to digitize hard-copy forms with the blockchain supporting the evidence and digital signature of the form.

    Sensitive data must often be stored off-chain since, by definition, on-chain data cannot be tampered with and cannot be deleted. To learn more about this, refer to the Private Data Collections overview in the Hyperledger Fabric guide. Off-chain and on-chain issues are the domain of the dev team architect and go to the heart of blockchain architecture issues that can make or break a blockchain application.

    We have already touched on smart contracts, also called chaincode, which is how developers manipulate data on the blockchain. Blockchain guarantees that no data on the blockchain can be modified or deleted without all the parties on the blockchain being immediately notified. This is an advantage that makes blockchain unique in the data world.

    After all, blockchain must interact with the real world. And this is where the concept of oracles comes in.

    Oracles are trusted data sources that provide deterministic information to a blockchain via smart contracts — deterministic is the key. For example, exchange rates change very quickly, and an outside data source can easily provide non-deterministic values such that as happened this morning the value of one Swedish Crown to one US dollar can be 0. The oracle manages the data sources that a blockchain depends on to ensure that they provide fixed values that allow the blockchain to handle the exchange rate in a deterministic way.

    Oracles should be architected into the blockchain solution from day one and should not be added later as an afterthought. This secure computing environment for microservices-based applications can be deployed without requiring code changes to exploit the security capabilities, and provides:.

    This is a set of standards that describe document processing, encryption algorithms, and other information technology standards for use within non-military government agencies and by government contractors and vendors who work with those agencies.

    Security Level 4 provides the highest level of security. At this security level, the physical security mechanisms provide a complete envelope of protection around the cryptographic module with the intent of detecting and responding to all unauthorized attempts at physical access. Penetration of the cryptographic module enclosure from any direction has a very high probability of being detected, resulting in the immediate deletion of all plain text Critical Security Parameters CSPs.

    Ordering services in Hyperledger Fabric and IBM Blockchain such as Kafka and Raft provide fault tolerant services, since a typical blockchain implementation is distributed and needs to be protected from going down. However, what happens if a business network is infiltrated by one or more malicious actors? After all, a network consists of a number of cooperating organizations, one of which could suddenly be taken over by rogue owners who could then try to take over the entire blockchain.

    The only problem is that for a permissioned blockchain system, PBFT can be heavily resource intensive and overkill. In other words, PBFT is not necessarily the most efficient method for solving the problem of rogue actors taking over a blockchain consortium.

    Permissioned blockchain systems are by definition guarded by laws and regulations that, if they are broken, can best be remedied in court and not by a resource-intensive technical solution. It is easy to spin up a Hyperledger Fabric instance and run the chaincode on the blockchain; the only limitation is that the blockchain will run on your own hardware and not in the cloud. Learn more about it here. Ultimately, most blockchain applications will be running in one or more clouds.

    IBM Blockchain Platform console, shown in Figure 3, makes it easy to spin up an enterprise blockchain application. Blockchain is one of the most exciting and promising new technologies to have appeared in the last decade. Developers all over the world are busy learning blockchain and applying it to problems that interest them. The key to success is to know the domain you are in, to leverage existing use cases, and to learn the blockchain programming model.

    And the way to quickly get started is to copy existing open source applications like the Blockchain Bean and then make successive changes on the existing code base. It is also important to fully realize the business and organizational aspects of your new blockchain venture. Yes, you need an architect with skills in cryptography and security, as well as a couple of programmers and domain and business experts.

    Ultimately, you should avoid getting overzealous in your blockchain enthusiasm, but focus instead on writing an application that provides real value for your first customer.

    And today you will almost certainly find your customers in the supply chain market segment. In addition, you should also be sure to read the excellent Hyperledger Fabric documentation.
