About Course

If you're a software developer and new to blockchain, this is the course for you. Several experienced IBM blockchain developer advocates will lead you through a series of videos that describe high-level concepts, components, and strategies on building blockchain business networks. You'll also get hands-on experience modeling and building blockchain networks as well as create your first blockchain application. The first part of this course covers basic concepts of blockchain, and no programming skills are required. However, to complete three of the four labs, you must understand basic software object-oriented programming and how to use the command line. It's also helpful, but not required, that you can write code in JavaScript. When you complete the course, you should understand what a blockchain business network is, how to build and model a simple blockchain solution, and the role of the developer in creating blockchain applications. If you choose to take this course and earn the Coursera course certificate, you will also earn an IBM digital badge upon successful completion of the course. You'll need to pass several end-of-section quizzes and a final exam that include multiple choice, true and false, and fill in the blank questions. This course does not cover Bitcoin or cryptocurrency in detail.

Course Syllabus

In this module, you'll get an overview of IBM and the Hyperledger Project, and get an introduction to Hyperledger Composer, a tool that helps you quickly model and build blockchain business networks. You'll also use Hyperledger Composer to model a simple business network that transfers a car among buyers, sellers, and other network participants.

Blockchain IBM opened a blockchain innovation research centre in Singapore in July 2016. A working group for the World Economic Forum met in November 2016 to discuss the development of governance models related to blockchain. According to Accenture, an application of the diffusion of innovations theory suggests that in 2016 blockchains attained a 13.5% adoption rate within financial services, therefore reaching the early adopters phase. In 2016, industry trade groups joined to create the Global Blockchain Forum, an initiative of the Chamber of Digital Commerce.
Blockchain Major applications of blockchain include cryptocurrencies—including bitcoin, BlackCoin, Dash, and Nxt—and blockchain platforms—Factom as a distributed registry, Gems for decentralized messaging, MaidSafe for decentralized applications, Storj for a distributed cloud, and Tezos for decentralized voting. Each cryptocurrency has its own features and particularities. Frameworks and trials such as the one at the Sweden Land Registry aim to demonstrate the effectiveness of the blockchain at speeding land sale deals. The Republic of Georgia is piloting a blockchain-based property registry. The Ethical and Fair Creators Association uses blockchain to help startups protect their authentic ideas.
Blockchain Distributed ledgers and other blockchain-inspired software are being developed by commercial organizations for various applications:
Blockchain The "Harvard Business Review" conducted a two-year research project exploring how blockchain technology can securely move and store host "money, titles, deeds, music, art, scientific discoveries, intellectual property, and even votes". Furthermore, major portions of the financial industry are implementing distributed ledgers for use in banking, and according to a September 2016 IBM study, this is occurring faster than expected.
Blockchain In 2016, the central securities depository of the Russian Federation (NSD) announced a pilot project based on the Nxt Blockchain 2.0 platform in order to explore the use of blockchain-based automated voting systems. Various regulatory bodies in the music industry have started testing models that use blockchain technology for royalty collection and management of copyrights around the world.
Blockchain Some blockchain implementations could enable the coding of contracts that will execute when specified conditions are met. A blockchain smart contract would be enabled by extensible programming instructions which both define and execute an agreement. For example, Ethereum Solidity is an open source blockchain project that was built specifically to realize this possibility by implementing a Turing-complete programming language capability to implement such contracts.
Blockchain The blockchain format was first used for bitcoin, as a solution to the problem of making a database both secure and not requiring a trusted administrator. The words "block" and "chain" were used separately in Satoshi Nakamoto's original paper in October 2008, and when the term moved into wider use it was originally "block chain," before becoming a single word, "blockchain," by 2016. In August 2014, the bitcoin blockchain file size reached 20 gigabytes. In January 2015, the size had grown to almost 30 gigabytes, and from January 2016 to January 2017, the bitcoin blockchain grew from 50 gigabytes to 100 gigabytes in size.
Blockchain The first blockchain was then conceptualised by Satoshi Nakamoto in 2008 and implemented the following year as a core component of the digital currency bitcoin, where it serves as the public ledger for all transactions. Through the use of a peer-to-peer network and a distributed timestamping server, a blockchain database is managed autonomously. The invention of the blockchain for bitcoin made it the first digital currency to solve the double spending problem. The bitcoin design has been the inspiration for other applications.
Blockchain The blockchain is parsed by software to extract relevant information.

Blockchain Blockchain technology can be used to create a permanent, public, transparent ledger system for compiling data on sales, storing rights data by authenticating copyright registration, and tracking digital use and payments to content creators, such as musicians. Imogen Heap's Mycelia service, which allows managers to use a blockchain for tracking high-value parts moving through a supply chain, was launched as a concept in July 2016. Everledger, "building systems to record the movement of diamonds from mines to jewelry stores", is one of the inaugural clients of IBM's blockchain-based tracking service.
Blockchain , Blockchain 2.0 implementations continue to require an off-chain oracle to access any "external data or events based on time or market conditions [that need] to interact with the blockchain."
Blockchain A blockchain facilitates secure online transactions. A blockchain is a decentralized digital ledger that records transactions across many computers in such a way that the registered transactions cannot be altered retroactively. This allows the participants to verify and audit transactions in an inexpensive manner. They are authenticated by mass collaboration powered by collective self-interests. The result is a robust workflow where participants' uncertainty regarding data security is marginal. The use of a blockchain removes the characteristic of infinite reproducibility from a digital asset. It confirms that each unit of value was transferred only once, solving the long-standing problem of double spending. Blockchains have been described as a value-exchange protocol. This blockchain-based exchange of value can be completed more quickly, more safely and more cheaply than with traditional systems. A blockchain can assign title rights because it provides a record that compels offer and acceptance. From the technical point of view a blockchain is a hashchain inside another hashchain.
Blockchain Blockchain protocols facilitate businesses to use new methods of processing digital transactions.
Blockchain Nikolai Hampton pointed out in Computerworld that "There is also no need for a ‘51 percent’ attack on a private blockchain, as the private blockchain (most likely) already controls 100 percent of all block creation resources. If you could attack or damage the blockchain creation tools on a private corporate server, you could effectively control 100 percent of their network and alter transactions however you wished." This has a set of particularly profound adverse implications during a financial crisis or debt crisis like the financial crisis of 2007–08, where politically powerful actors may make decisions that favor some groups at the expense of others. and "the bitcoin blockchain is protected by the massive group mining effort. It's unlikely that any private blockchain will try to protect records using gigawatts of computing power — it's time consuming and expensive." He also said, "Within a private blockchain there is also no ‘race’; there's no incentive to use more power or discover blocks faster than competitors. This means that many in-house blockchain solutions will be nothing more than cumbersome databases."
Blockchain By 2014, "Blockchain 2.0" was a term referring to new applications of the distributed blockchain database. "The Economist" described one implementation of this second-generation programmable blockchain as coming with "a programming language that allows users to write more sophisticated smart contracts, thus creating invoices that pay themselves when a shipment arrives or share certificates which automatically send their owners dividends if profits reach a certain level."
Blockchain The credit and debits payments company MasterCard has added three blockchain-based APIs for programmers to use in developing both person-to-person (P2P) and business-to-business (B2B) payment systems.
Blockchain In 2016, venture capital investment for blockchain related projects was weakening in the USA but increasing in China. Bitcoin and Ethereum use open (public) blockchains. , bitcoin has the highest market capitalization while Ethereum is second.
