In this chapter we build our first web front end to our blockchain network. We will start with the administrative interface, which supports the basic management of the network (deploy, undeploy, ping, update) and working with Members and Assets. You will note that there is an option to pre-load the network and that, in addition to what you saw in the video, there is now an active window at the bottom of your browser which is showing all of the blocks as they are created and added to the block chain.

Ready to learn more about the blockchain technology? The internet has a short history when compared to the time that we have had life on earth. But in this very short period of time, it has taken mankind by a storm. There have been several transformation on the way we transact, and communicate since the time internet was developed. The manner in which we maintain a record of transactions and contracts create the basics of our economic, legal and political system. These instruments help us in protecting our assets and setting organizational boundaries. The record of every transaction or contract helps in the establishment and verification of identities as well as in chronicling events. They oversee the interactions between nations, organizations, communities and individuals. This explain...
This video is a demonstration of the Ethereum Blockchain solution developed by our team for the Blockchain Virtual GovHack. The demonstration shows the multiple Ethereum nodes built for a solution that allows for UAE Property Title Deeds to be stored on a Government Land Registry. The solutions caters for asset ownership transfer from Property Seller to Buyer, approved via the Land Department and demonstrates possible integration with other Government entities like DEWA. We developed this Blockchain solution in less than 4 weeks specifically for the hackathon, and leveraged the Makani API to get GPS location data for properties. We also utilized an IPFS document management platform to store documents like the EmiratesID, Title Deed document, Tenancy Contract and Ejari Certificate again...
So as it stands there are three types of Blockchains available, and all three have there own positives and negatives. So we have public blockchain’s, consortium blockchain’s, and private blockchain’s. // VIDEO TAKEN FROM // View: https://www.udemy.com/blockchain/?couponCode=YOUTUBE10 // FREE BITCOIN WEBINAR // Join: http://bit.ly/2AR6v2v // CRYPTOCURRENCY & BLOCKCHAIN TUTORIALS // Sign-Up: https://www.b21block.com // FOLLOW ME ONLINE // Subscribe: https://youtube.com/c/RavinderDeolB21Block?sub_confirmation=1 Like: https://facebook.com/B21Block
Looking at the major differences between a private Blockchain with a public blockchain. Within a private blockchain we also know the participants in the network so we take a look at how we add a new participant into a blockchain network to know who they are.

The network in Hyperledger Composer is defined by creating a: model file (sample.cto), which describes the members, transactions and assets in the network access control file (permissions.acl) transaction logic (/lib/sample.js) test logic (/test/sample.js) We will create each of these files and then use both the Composer Playground on Bluemix and also the REST services to interact with our first network.
Blockchain may be best known today as the technology that underpins the digital currency bitcoin, but it can also be used for a host of other purposes that involve transmitting data securely. “Blockchain technology represents nothing less than the second generation of the internet,” says Alex Tapscott, CEO of consultancy Northwest Passage Ventures and co-author of the book Blockchain Revolution. Blockchain is set to transform financial transactions and reporting and, in turn, tax as well. Watch EY’s Michael Meisler and Rod Roman talk about the role that blockchain may play in the future of tax. Read more about our Tax Insights: http://taxinsights.ey.com/

Blockchain explained in plain English Understanding how blockchain works and identifying myths about its powers are the first steps to developing blockchain technologies. Blockchain is an algorithm and distributed data structure for managing electronic cash without a central administrator among people who know nothing about one another. Originally designed for the crypto-currency Bitcoin, the blockchain architecture was driven by a radical rejection of at (government-guaranteed) money and bank-controlled payments. Blockchain is a special instance of Distributed Ledger Technologies (DLTs), almost all of which have emerged in Bitcoin's wake. HOW DOES BLOCKCHAIN WORK? Blockchain is a Distributed Ledger Technology (DLT) that was invented to support the Bitcoin cryptocurrency. Bitcoin was ...
This is part 8 of the Blockchain tutorial explaining what logarithms are. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology c...
Events help us understand and act on what's happening in the network. In this chapter, we will update our system model to support events for each state change in an order and then update the chaincode to issue these events if a transaction successfully completes. We then update our nodejs server code to listen for these events and then let the browser know about events as they relate to various roles. We will create an event notification icon and update it in real time as events occur in the blockchain business network.

The Buyer is the beginning of the process. They have the ability to create orders, submit a purchase request, cancel an order, approve payment for an order and raise a dispute. They are the only role, other than the administrator, who can create an Order asset. They can issue some transactions, but not all. We need to interact with the composer created transactions and leverage the ACL to ensure that the buyers can do what they need, while restricting them from issuing inappropriate transaction requests.

The National Aeronautics and Space Administration (NASA) in conjunction with the University of Akron (UA) has just initiated a new research program that will see the two scientific groups come-together to implement Ethereum-based blockchain technology for the purposes of space communication and navigation. Faculty member from their Electrical and Computer Engineering department, Jin Kocsis, received a grant in excess of $330,000 for her research on the topic of “Resilient Networking and Computing Paradigm (RNCP)”. The Center for Blockchain Studies, our group within Black Blockchain Consultants, will pursue similar research grants. As black people, we should pursue this $3.1 trillion industry. https://cryptoslate.com/nasa-initiates-independent-research-on-the-ethereum-blockchain/
