    This way, the transactions are linked so that it can keep a proper note on expenditure done in the blockchain. The last important part of blockchain architecture is consensus. It is the method through which a transaction and is validated. Each blockchain can have a different consensus method attached to it. There are other types of consensus methods as well that we are going to list below.

    Consensus algorithms offer a set of rules. It needs to be followed by everyone in the network. Also, to impose a consensus method, nodes should participate. Without any node participation, the consensus method cannot be implemented. This also means that the more nodes join to participate in the consensus method, the stronger the network begins. Bitcoin has a big network and offers a great incentive to become a miner. In fact, it also has one of the biggest miner communities out there.

    The miners sometimes also follow their allegiance when it comes to making their point. For example, if there is a change required in the blockchain, miners can decide to at least protest against the change. They can fake transactions and also make it possible to do double-spending. If you want to learn how does blockchain work in a step-by-step process, then we can go through it below.

    Step 1: In the first step, a transaction is requested. The transaction can be either to transfer information or some asset of monetary value. Step 2: A block is created to represent the transaction.

    However, the transaction is not validated yet. Step 3: The block with the transaction is now sent to the network nodes. If it is a public blockchain, it is sent to each node. Each block consists of the data, the previous block hash, and the current block hash.

    Step 4: The nodes now start validating according to the consensus method used. In the case of bitcoin, Proof-of-Work PoW is used.

    Step 5: After successful validation, the node now receives a reward based on their effort. All of these processes can offer you the highest level of security in the network. Now that we have understood the core components of any blockchain network, we should also learn about the different types of blockchain architecture. In a public blockchain architecture, anyone can participate in the network. Examples of public blockchain architecture include bitcoin, Litecoin, and Ethereum. When it comes to private blockchain architecture, not anyone can access the blockchain.

    The administrator or the ruling set of nodes determines who can join the network. Want to understand the differences between public and private blockchain? It combines the best features of both public and private blockchain. It is also heavily controlled and is best suited for enterprise blockchains. Consensus methods are an integral part of any blockchain type. It determines how fast, efficient, and secures a transaction is. Right now, there are tons of consensus methods out there.

    But for simplicity of discussion, we are going to cover the top four popular ones. It is the first-ever consensus method used by a blockchain network. It was introduced with bitcoin. In this consensus method, there are miners who are responsible for validating a transaction. The hash of a new block is needed to be found so that it can be added to the network. The one who finds the first one gets rewarded with others.

    Blockchain Proof of Work requires extreme computational power and also has high requirements when it comes to hardware. Proof-of-Stake is used by 2nd generation blockchain network, Ethereum. Here coins are staked by the nodes. Ethereum has its own requirements on how coins need to be staked for it to be eligible to take part in the consensus algorithm.

    The nodes that have more coins staked have more chances to get rewarded. This also makes Proof-of-Stake investment heavy. DPoS is a different type of PoS. It handles the node selection differently. The coin holders, in this case, select the nodes to take part in the consensus method.

    They can also vote while choosing or kicking a node. It is more suited for an established network with more trust. You can use this technology for blockchain business models. It enables nodes to decide whether to accept or deny the submitted information. The party maintains an internal state which is used to run a computation on new messages.

    If the party computation runs well, it then decides to share the transaction with other parties within the same network. As not all nodes are required for the consensus method, it also has a low hash rate requirement. However, to make it successful, it requires well trusted nodes to work together. In this section, our focus would be on the enterprise blockchain use cases. The blockchain use-cases will help you understand blockchain technology better.

    There are hundreds of blockchain use cases, but we are going to list only a few of them below for the sake of simplicity. Supply Chain Management currently suffers from a lot of problems. For example, the biggest problem in SCM is product counterfeit. By using blockchain for supply chain , products can be traced accurately, removing any counterfeit possible. It also improves transparency and ensures that there is a cost reduction on the whole part. Improvements in SCM also mean an improvement in different industries, including healthcare, food industry, etc.

    If you are curious about how blockchain can positively impact the world of supply chain, and in particular, management operations, then you must enroll in our enterprise blockchains and supply chain management course now! Healthcare also benefits from the likes of blockchain. With blockchain for healthcare , it will now become possible for patients to have their reports stored on blockchain — which can be retrieved later on.

    This way, doctors can work on a single report and give better medical services to them. It also makes the process efficient, improves the exchange of information, and brings the best possible way for patients to secure their documents to not have to carry them. What Diana and Ross need is a smart contract. Diana is selling football for 70 ETH.

    Ross wants a football so he sends Diana 70 ETH. Both parts of the contract have to happen for the transaction to be completed.

    Which transaction would you prefer? They can be used for lots of different things. Solidity smart contracts can be used to guide all kinds of transactions from secure voting in elections to rental agreements. Solidity is a high-level coding language.

    This means that it is designed to be read and used by human beings! Computer programs are usually written in a high-level language and then translated into a low-level coding language. Now, if you really want to know how to become a blockchain developer, you must learn about low-level coding languages also.

    A low-level coding language is designed to be read and used by computers. Low-level languages are made up of 1s and 0s. This is called binary. When a blockchain developer builds dApps and smart contracts on the Ethereum blockchain, there are rules which guide their design. For example, if you want to design a new cryptocurrency using Solidity you have to follow a set of rules called ERC These rules make it easier to tell how new dApps will work when they are launched on the blockchain.

    Ethereum blockchain development happens in a very special place called the Ethereum Virtual Machine. A virtual machine is an environment where new computer programs can be written. You would build and test your car in a factory and on empty streets. This is how the EVM works. It is a factory for building new smart contracts. This makes Ethereum a great place to learn blockchain.

    The EVM allows users to practice blockchain programming without worrying about making mistakes. The EVM is also Turing complete. This means that whatever a computer can do, you can design using the EVM. The only limit is your imagination! Think of all the exciting new ideas being built using the EVM right now! Learning Solidity is a lot like learning to speak a new language , but it is essential to become a blockchain developer on the Ethereum platform.

    Solidity basics are like nouns, adjectives, and verbs. Nouns, adjectives, and verbs are tools for creating sentences. Here are some of the tools for creating Solidity smart contracts;. Variables - These are used to store information on the blockchain.

    There are lots of different kinds of variables but here are some of the most common:. Booleans - These are used to store information that is either true or false.

    The keyword for Booleans is bool. Integers - These are used to store information as a number. There are two types of the integer. Regular integers can be positive or negative numbers. Their keyword is int. Unsigned integers can only be positive numbers. Their keyword is uint. Addresses - These are used to store Ethereum addresses. Each Ethereum user has its address or addresses on the blockchain. Diana and Ross, from the example earlier, would both need addresses for their smart contract to work.

    Strings - These are used to store text information. Their keyword is strings. Functions - A function is used to do a certain job. A function can use information from variables to create new information. For this sum, the keyword would be function add. This is what sums look like in smart contracts;. Structs - These are used to put variables into groups. Do you remember that new car you were building? In Solidity, you could use a struct to group information about your car!

    It would look something like this:. Not only are there basic courses, but also game-courses that could teach you! Two courses that teach you how to become a blockchain developer are Space Doggos and CryptoZombies. Space Doggos and CryptoZombies are both gamified Solidity lessons for beginners.

    This means that they both turn Ethereum blockchain into a game! Space Doggos allows beginners to learn blockchain development by creating characters and environments for an adventure in space. The first lesson contains ten chapters of information and tasks to get you started. Each chapter has detailed notes on the processes being used. These include the variables, functions, and structs I talked about earlier.

    Users can design their astronaut dog using real Solidity code. The code becomes more complicated as the adventure continues. As an introduction to the Ethereum blockchain, Space Doggos is a well-designed and entertaining platform for any upcoming blockchain developer. CryptoZombies allows users to design a whole army of zombies.

    To do this, users first have to build a zombie factory. Then, users can code the way their zombies look and even the way they attack their victims! CryptoZombies is very entertaining and makes a lot of difficult ideas fun. So, if you want to command an army of the undead, then CryptoZombies is the course for you. However, I would recommend Space Doggos. For this, I would recommend the BitDegree Solidity course.

    The BitDegree Solidity course is great for users who have learned Solidity basics and are ready to start blockchain programming. The course starts with the environment setup and takes users through to building and launching their cryptocurrency!

    We've covered the topic quite in-depth, but if you're more of a TL;DR kind of a person, let's see the shorter version of the steps you should take if you want to master blockchain developing:.
