Blockchain Terminology Review Now one of the resources I’m going to request you take a look at before you take the exam is on the Blockchain Training Alliance website and it would be under resources here. It’s basically glossary of blockchain terms. Now the reason I’m going to ask you to do this is because oddly enough, a lot of these terms you’re going to see again on the exam and no better a resource than to go to the source for the right definition, right? So let’s go ahead…

Bonus Lecture -R3 Corda Whiteboard In this whiteboard. Let’s go through a transaction lifecycle. This is going to be between its creation and the inclusion to the ledger. Now up here we have the three states that will occur. The first date that has to happen, especially if you’re going to be using the API, is to understand that the transaction lifecycle has three specific states. The first is the transaction builder. This is going to be essentially creating the transaction. This is going to be step one. Now, step…

Bonus Lecture – Facebook Libra Demo on Google Cloud Platform Welcome aboard, everyone. Let’s go ahead and talk about installing the Libre testnet on Google Cloud Platform. Now, to install the Libretest net on Google Cloud Platform is a relatively simple process. Now you can go ahead over to the link in the description and download the instructions. The instructions are going to essentially look like this. So let me go ahead and bring over my screen and show you what they look like. Now, when you download this PDF…

Comparing enterprise blockchains Enterprise blockchain. So let’s go ahead and talk about enterprise blockchains. Now, the exam itself is really going to focus on three blockchains. The main blockchain is going to focus on is Ethereum, hyper, ledger and Bitcoin. Let’s just clarify, Bitcoin is not an enterprise anything, it’s a cryptocurrency, right? So it’s not a blockchain, it doesn’t support smart contracts, at least from a wide scale perspective. There’s a way to run them, but it’s not going to be efficient by any means. But that’s another story…

Objective – Value Creation Let’s talk about value creation and blockchain. Now, anytime as an architect we want to go ahead and derive an architecture or to try to sell a solution. We have to be able to determine the value and display that to the customer. We want to realize that blockchain technology has some specific value creation benefits if it is a right use case for the technology. And around that we’re going to be looking at costing, security, privacy, efficiency and it is open source as well….

Objective – History of Blockchain This objective. Let’s talk about the history of blockchain. Now, there’s going to be a couple of dates that you’re going to want to remember. Not so much dates as in days and months, but more or less years. So let’s go and talk about the first one. We want to understand the Buys and T general problem. 1982, this is when that issue came up around how do we get the nodes to basically agree on specific consensus related concerns. Right now, when it…

Objective – Security in Blockchain and how addresses, public keys, and private Objective. Let’s talk about security and blockchain and how it addresses public private keys and how they all work. Let’s talk about a private key and a public key. Basically a private key and a public key are part of encryption and these encryption methods are going to be used to encode information. Basically we need a way to basically take plain text and transfer it into cipher text. Now when we look at encryption systems, it’s generally…

Objective – Consensus among Blockchains Let’s go ahead and talk about consensus. Now, when it comes to consensus, this is a course area that will be tested, I guess, in a way probably significantly more than perhaps other sections. There’s a lot here to talk about, and we definitely want to make sure you understand the reason to use specific consensus methods and why specific blockchains use proof of work, proof of stake, d, POS, poet, et cetera. But let’s clarify what consensus is. Consensus is a dynamic way of…

Application Insights Application Insights are a set of tools for specifically monitoring application level events and statistics. In order to use them, you must install an instrumentation package within your application. App Insights can be used in many different platforms, including Net, Node, JS, and Java, and it can be used to monitor both cloud and on premise applications. With App Insights, you get a full end to end view of your application from front end services, middle tier services, and back end databases and storage. It allows you to…

Log Analytics Azure captures an incredible amount of log data and as such it can be difficult to find and visualize what you need. For this reason, you can create a Log Analytics Workspace, which is a powerful tool for querying those logs to find the information you need. The Log Analytics Workspace is also required to provide other management capabilities such as advanced report and update management. Log analytics can query across many different data sources, including Windows event logs, Windows performance counters, Linux performance counters, custom fields, custom…
