Blockchain CBSA – Objectives – Hyperledger Part 7

Hyperledger Composer Demo Now what we want to do is add our protocols for web traffic, which is going to be Http and Https. Now port 80 is fine. We’re going to go ahead and leave this as the default. I’m going to add another rule. I’m going to go over here, put in Https and actually select Https and there we go. Those are the two ports that we need to have open to access, for example, web traffic to that VPC, but also any VMs inside of the…

AWS Managed Blockchain (DEMO ONLY) No support and not on the exam Alright, well, let’s talk about AWS manage blockchain in this demo. Now this is a very new service. At the time of writing, this is still in preview mode, so you need to be basically authorized to access the service. However, by the end of April, early May 2019, this should be general availability. So let’s talk about what exactly this is. So this is actually very similar to how things work essentially with IBM blockchain as a…

Deploy AWS with Hyperledger Fabric Part 2 (DEMO ONLY) No support & not on exam Okay, we’re getting down to the point where we might be able to deploy our cloud formation stack soon. Now, we’re not done yet, so again, I said might because we still got some more work to do. Now what we want to do is we need to create basically a policy. What we need to do is add basically ECS and EC Two, S Three for Cloud Formation to do its work. Now for…

IBM Baas Demo (DEMO ONLY) No support and not on the exam I’m over here at the IBM Cloud website. What I like to do is walk through a demo of some of the functions and capabilities of the IBM blockchain as a service. So let’s go over here to blockchain and you can see it pops up blockchain there and it’s going to bring up a service name and, and location as well. But before we get into the capabilities and spin up some peers, for example, and install…

Demo – Channels Now I’m in the IBM blockchain as a service starter plan and what I like to do is just talk about channels and just deploy an additional channel. So when we create a channel we want to go over here to channels and it will go ahead and bring up the channel interface. And it usually doesn’t take this long, but sometimes it does. But you can see that we have a channel that is the default channel. This is created automatically for us when we deploy…

Hyperledger Fabric Whiteboard Discussion Okay I’m over here at Aww Amp. com. This is a free whiteboard solution and what I’m going to do is just walk you through the steps through a transaction because I think it’s important to talk about some of the node types, the peers, but also how the transactions occur. So I did a quick little diagram and I have my MSP and the CA up here. The MSP is the membership service provider and the CA is a certificate authority. We have our client…

Blockchain CBSA – Objectives – Hyperledger

Hyperledger Project Let’s talk about the Hyperledger project. Hyperledger is more than just hyperledger, Fabric. It’s really a project. So let’s talk about it. Now, Hyperledger is an open source project that came out of the Linux Foundation. It’s a global collaboration. Essentially. It’s hosted by the Linger Linux Foundation. It has a governance structure, it’s open source as well. Now the project itself consists of essentially three main components. It has the infrastructure component, the framework, and the tool component as well. Let’s go ahead and talk about these….

Blockchain CBSA – Objective – Ethereum Part 3

Ethereum Security Well, let’s talk about Aetherium blockchain security. Well, we know that Aetherium is a public non permission blockchain. We also know that it’s open to the public. We know that it’s using proof of work and at some point when it gets to the right block number it will change over to a proof estate consensus. Now, Aetherium was originally designed to be a smart contract platform and again, it’s perhaps the most well used smart contract platform out there. With that said, we want to be aware…

Blockchain CBSA – Objective – Ethereum Part 2

Ethereum Gas Estimates I’m over here at the Ether gas station. The link is here. It’s basically Ethan info. I’m over at the home page here. You can see here that it’s got the gas time to price estimator tells you the approximate use case and the cost involved tells you the count by gas price. In other words, again, percentage of transactions fall into a specific range. It seems like between four, but less than 20 seem to be about 60% of the transactions. Sort of an interesting thought…

Blockchain CBSA – Objective – Ethereum

Ethereum Overview In this module. Let’s cover the objectives around Aetherium for this exam. Now, Aetherium is of course one of those subjects that’s far and wide. It’s definitely not a 20 minutes subject to cover Ethereum. Technically and in detail it’s literally a three day class. But I want to ensure that we understand the basics of a theory theorem, especially for the CBSA exam. Now, the good part about this exam is it’s not going to dive into anything really technical. It’s more factoids, as I like to…
