The Complete Blockchain Professional Course

In this lecture, you will learn how blockchain works, with the help of an example. This example will give you insight as to how the blocks in the blockchain are linked to each other and also provide you the knowledge about the functioning of the nonce in the blockchain.

In this lecture, you will learn about different types of wallets, digital signatures and protocols.

In this lecture, you will learn about the benefits of blockchain over traditional technologies. We will also see the overview architecture for blockchain, which is bases on peer to peer connections and traditional technologies, which is based on client server model.

In this lecture, we will break the myth of Bitcoin being the blockchain. We will see how bitcoin is only one of the mainstream manifestations of blockchain. We will also talk about how blockchain holds the potential for disrupting various industries.

In this lecture, you are going to learn about the key generation algorithms used with Blockchain. We are also going to talk about the concept of addresses in Blockchain.

In this lecture, you are going to learn about transactions and how transactions are incorporated inside a Merkle tree to form the validation process for the block. We are also going to learn about the key components of a block with the example of a Bitcoin block.

This is a bonus lecture provided for the key concepts. We are going to talk about some additional concepts related to the Hierarchical Deterministic Wallets which are used for hierarchy processes, Mnemonic Seeds for protection of wallets and Smart Contracts for running business logic between two or more parties.

This lecture will give you an overview of how a Blockchain transaction works and why it is better than traditional transactions.

Let's first understand the problem related to the Internet and Peer to Peer networks. In this lecture, we are going to discuss the two generals problem related to the internet and also the generalized version of two generals problem related to the peer to peer networks.

After defining the problem, we will go into a probable solution provided for the generalized version of two generals problem. With the help of an example, we will understand how the solution is defined. This lecture is oriented to provide the solution in most layman terms possible.

Once we understand the solution to the generalized version of two generals problem, we will map the solution to the blockchain world. We will see how blockchain utilizes the concepts defined in the solution to work securely.

Apart from Byzantine Fault Tolerance, we have one more concept which makes sure that no conflicts arise in the creation of blocks. This concept is known as the Longest Chain Rule. In this lecture, we will discuss the longest chain rule and also understand how the longest chain rule resolves the conflicts in mining.

In this lecture, you will learn about the pioneer consensus algorithm known as Proof of Work. We will also talk about Bitcoin as one of the example projects utilizing Proof of Work consensus algorithm.

In this lecture, you will learn about the Proof of Stake consensus algorithm which avoids the pitfalls of the Proof of Work consensus algorithm. We will also talk about Neo as one of the example projects utilizing the Proof of Stake consensus algorithm.

In this lecture, you will learn about the Delegated Proof of Stake consensus algorithm which provides a completely different approach from the Proof of Stake consensus algorithm. We will also talk about Lisk as one of the example projects utilizing the Delegated Proof of Stake consensus algorithm.

In this lecture, you will learn about the Proof of Authority consensus algorithm which is similar to Proof of Stake consensus algorithm but miners need to stake their identities to earn the rewards. We will also talk about Proof of Authority network as one of the example projects utilizing Proof of Authority consensus algorithm.

In this lecture, you will learn about the Proof of Weight consensus algorithm which is a broad classification containing different types of consensus algorithm. We will also talk about Filecoin as one of the example projects utilizing Proof of Weight consensus algorithm.

In this lecture, you are going to learn about different categories of Blockchain. We will discuss about public, private and consortium Blockchain. We are also going to compare the different Blockchain categories.

In this lecture, you are going to learn about the Blockchain architecture. We will talk about some sample architectures and define how you can create your own architecture.

Note: Blockchain architecture discussed here is a sample architecture, you can use similar types of architecture for your use cases. There is no standard definition of architecture, we can define it as per the services we require for our solution.

The first step in defining our solution is to identify the Use Case. Blockchain is not a silver bullet and we cannot consider it to be a solution to all the problems. We need to identify a suitable Use Case, where Blockchain could be cost-effective and productive.

The next step in forming a Blockchain solution is to design the integration strategy with the existing architecture and applications. The new solution should seamlessly integrate and not break our present ecosystem.

After designing Integration strategies, we go into identifying the appropriate consensus mechanism to be used with our Use Case. There is no single consensus mechanism which could fit in with all the problems. We need to identify which consensus mechanism suits the best for our needs.

After Identifying the consensus mechanism, we go into identifying the platform. There are multiple platforms available in the market which provides different feature set. We need to choose the most suitable platform for our Use Case.

The next step is to design the architecture for our solution. As mentioned in the course, there is no concrete definition for Blockchain architecture. You need to define the services as required. You also need to understand whether you require public, private or hybrid solution.

The next step is to design your Blockchain instance. This is one of the most important steps for defining your Blockchain solution. In this step, you define all the parameters required for your Blockchain which will be followed throughout the lifetime of the Blockchain.

Now we will go into building the Application Programming Interface. You need to take notice about which functions you want to expose to developers and users. Developers can use your APIs inside their applications to interact with your Blockchain.

Finally, we go into building our applications, which will be used by the users to interact with the Blockchain. Users cannot work with command line interface and require a good UX application to perform operations over the Blockchain. We will also define future prospects and opportunities for Blockchain solutions.

In this lecture, we are going to learn about the Blockchain technology stack. We will understand different support systems, protocols, and overlay networks that form the complete technology stack.

Only having an idea or Blockchain solution is not good enough. You need to build a complete ecosystem around your solution which will help your project grow. In this lecture, we are going to learn about different parts of the Blockchain ecosystem and why you need to maintain all these parts?
