Working of dApps

As we are discussing the dApp blockchain connection, it is important to dig deeper into the design of dApps. Decentralized applications include a frontend and a backend as the two important components in their design. The frontend helps in communicating with the user, while the backend code is basically a smart contract. Now, the smart contract is where blockchain jumps in the answers for ‘what is dApp’ and most prominently refers to the Ethereum blockchain. 

The front end of the decentralized application is actually the code executed on the user side of an application. It basically serves as the interface for communication between the user and the application. In addition, the frontend of dApps also includes a digital wallet that serves different functions. 

The digital wallet maintains a record of private and public keys of users for authentication purposes. In addition, the digital wallet helps in interacting with blockchain for management of blockchain addresses and cryptographic keys. The digital wallet in the dApp frontend also helps in triggering the execution of backend or smart contracts. 

The backend of decentralized applications brings an interesting twist with the use of smart contracts running on the server-side of the application. You have the backend of dApps on a blockchain where it is executed, and the backend of dApps is open source in nature. The smart contracts perform the specifically defined functions irrespective of the conditions in their surroundings.

Differences between Decentralized Apps and Traditional Apps

Twitter and Slack are some of the conventional examples of companies offering web applications. Traditional web applications also depend on the frontend and backend as the important elements in their functionality. However, traditional web applications leverage software that resides on centralized web servers rather than the local operating system of specific devices. The devices would leverage the Hypertext Transfer Protocol or HTTP for using coding messages to communicate with servers. So, the feed on the front end of the web application would come from data in the backend or web server of the company. 

A decentralized app uses a smart contract on a blockchain network as its backend. Blockchain is basically a network of multiple machines sharing the same transactional burden in a distributed network. You can find that a dApp leverages the same technology for rendering the page on the frontend. However, dApps differ from web applications in terms of their backend as they communicate with relevant blockchain networks by leveraging a wallet.

Significance of Wallets in Decentralized Applications

Suppose you are trying to find out answers to “What is dApp used for?” then you should take a look at how wallets serve as an important component in dApps. The wallets help in managing a user’s blockchain address alongside the cryptographic keys required for their identification and authentication. 

Rather than depending on HTTP protocols, the wallets are responsible for triggering smart contracts or the backend of dApps. The smart contracts would then interact with blockchain network and ensure the execution of transactions. Since smart contracts are programmable code that you can tailor according to specific use cases, the dApps can work for a wide range of use cases. 

Key Features of Decentralized Applications

Another key highlight that you should discover in discussions around ‘what is dApp’ is an outline of the key traits of dApps. Now, you have a clear impression of the basics of decentralized apps and how they work. So, this would be the best time to take a look at the following features of dApps which distinguish them profoundly.

Decentralized applications are basically traditional web applications which you would run on a blockchain network. So, what does a dApp offer in terms of value for users? Here are some notable advantages you can find with decentralized applications. 

• No Downtime

The foremost advantage of dApps refers to the fact that there is no downtime with them. After deploying the smart contract on the blockchain, the network can always serve the needs of clients who want to interact with the smart contract. Furthermore, dApps can also ensure that any malicious actors cannot launch denial-of-service attacks on specific apps. Since a decentralized application runs on a peer-to-peer system, it will continue to function even if parts of the network architecture are non-functional.

• Censorship Resistance 

Another important aspect about dApps that expands the scope of answers to “What is dApp used for?” refers to censorship resistance. Decentralized apps do not allow control of the data and processes to a single entity. Therefore, it is impossible for any government or entity to block users from submitting transactions or deploying dApps, and even reading data from the blockchain. Without any specific individual or organization controlling a dApp, users have the advantage of complete freedom with dApps. 

• Trustless Computation 

The next crucial value advantage associated with dApp blockchain interplay refers to the analysis of smart contracts and predictable execution without any centralized authority. Decentralized apps establish the foundation of truly trustless systems as compared to traditional models. 

For example, you have to trust the financial institutions in online banking systems and assume that they would not misuse your financial or personal information. However, you don’t have to rely on a central authority anymore with a dApp as the smart contract takes care of everything. 

• Privacy

The most dominant advantage of decentralized apps, which clearly strengthens an understanding of ‘what is dApp’, is anonymity. You would find that a major share of decentralized applications does not demand the real identity of users.

Decentralized applications present many complications in terms of maintenance due to difficulties in the modification of code and data published on the blockchain network. Developers could not deploy updates to the apps, even in the event of identifying bugs or security risks. 

• Network Congestion

The issue of network congestion becomes clearly evident in cases where one dApp consumes an excessive amount of computational resources. As of now, the Ethereum network could process around 10 to 15 transactions every second. However, sending transactions at a faster rate could lead to faster expansion in the number of unconfirmed transactions.

• Centralization 

While a decentralized application might look like a solution built on Ethereum, it may feature some centralized traits. For example, some dApps could store the keys or other sensitive information on the server-side or execute sensitive business logic on centralized servers. 

• Performance Overhead

The next dominant risk associated with dApp examples would refer to the massive performance overhead and difficulties in scalability. Every node in the network has to run and store each transaction for ensuring the desired levels of security, reliability, integrity, and transparency in a dApp. Furthermore, the consensus mechanisms such as Proof-of-Work also consume time and resources. Therefore, the overhead with dApps is massively larger than the overhead of standard computation. 

• User Experience

Another notable setback for decentralized applications would refer to the difficulty in user-friendly engineering experiences. The average end-user would encounter difficulties in setting up a tool stack for interacting securely with the blockchain. 

Examples of Decentralized Applications

An introduction to dApps will be incomplete without mentioning a few popular dApp examples. Some of the common names among dApps that are popular today include Augur, BitTorrent, and Golem. Augur is one of the top entries among dApp examples, with more than 100,000 monthly visitors to its website. 

It is an open-source, decentralized prediction marketplace based on Ethereum, which helps in creating different prediction markets.

For a newbie, both might sound similar. However, that’s not true even when many people out there consider blockchain “just another database.”

Also, you will find people searching for blockchain vs distributed database? Is there anything called “distributed database”? Or blockchain is simply a distributed database? We will answer all of these questions below.

Blockchain is more than just a database, and this article aims to a detailed comparison of blockchain vs. database.

Blockchain Vs Database: What Is Blockchain?

But, if you are new, don’t worry; we will cover blockchain in brief here before jumping into blockchain vs. database comparison. The basic definition of both database and blockchain will help us understand the blockchain vs. database comparison. Let’s get started.

Blockchain is a distributed ledger technology that enables a set of peers to work together to create a unified, decentralized network. The peers can communicate and share information or data with the help of the consensus algorithm. Also, there is no need for a centralized authority, which makes the whole network trustworthy when compared to other networks.

Let’s take a look at an example to understand how blockchain works. When one peer sends information to another, a transaction is generated. When this happens, the transactions need to validated using the consensus algorithm.

In this case, Proof of Work is used to validate the work. It ensures that no invalid transactions are passed into the blockchain. Blockchain is all about blocks. They are used to store transactions and other important information that is required to operate the blockchain successfully.

Timestamps are created to ensure that each transaction can be traced, backed, and verified by anyone. The whole system adds value and brings in new features such as transparency, immutability, and security.

What Is a Database?

With the idea of blockchain clear, it is now time for us to understand the database. The database, unlike blockchains, are a centralized ledger that is run by an administrator.

Databases also exhibit unique features, including the ability to read and write. Here, only the parties with proper access can do Write and Read actions. Databases also exhibit the ability to store multiple copies of the same data and their history. This is done with the help of a trusted, centralized authority who manages the server.

Centralization brings many benefits to the database. For example, it is easy to manage databases as the data is centralized. Accessing and storing data is not only easy but also fast. However, they also have drawbacks.

One of the biggest drawbacks is the chance of the data getting corrupted. To overcome the disadvantage, multiple backups are taken. But, that’s not always the case, as most of the entities always trust their owner and hence skip the backup data option. Another big drawback is how the data can be modified by anyone who is in control of the database itself. This can happen as the database is centralized in nature.

A Technical View

Now, let’s look at the database more technically.

A database utilizes data structure to store information. All the data that is stored in a database can be queried using a special querying language known as Structured Query Language (SQL). A database can work with almost every type of data and help support all modern enterprises. Also, it can be scaled to support millions of records.

The history of the database is also rich. It started with just hierarchical file systems. It had severe limitations, and hence it then later adapted to the relational model. The relational model is useful and gives the owner the ability to work with different databases at the same time. Database management systems are used to organize databases effectively.

At the core, data elements are stored in tables. The table consists of fields that can record a different type of data, known as attributes.

Without a proper business model in mind, it’s difficult to use blockchain as leverage. Check out our ultimate blockchain implementation strategy to learn more about developing blockchain.

Private Blockchain Vs Database: Are these Same?

There are many different types of blockchain. For example, we have a private blockchain that works in a closed ecosystem.

This may sound similar to what databases are about, but they are fundamentally different. Private blockchain inherits all the properties that a blockchain has to offer, but it works in a closed environment. Only people who are allowed by the administrator can participate in the blockchain. The only similarity between private blockchain and database is the centralized aspect.

Blockchain vs. Database

With each of the terms clear, it is now time for us to make the actual comparison. We will compare both the technology using important pointers, where we will discuss how they compare. Each pointer will also contain examples to ensure clarity and understanding. So, without any details, let’s get started.

Blockchain vs Centralized Database: Authority and Control

If we compare blockchain and database, the first thing that you will notice is how authority works. Blockchain is designed to work in a decentralized manner, whereas the databases are always centralized. This unique feature of blockchain gives it the leverage it needs to become the next generation of technology.

Decentralization brings in a lot of implementation changes to the current systems and processes used by the different industries. It empowers networks to work independently and removes any need for centralized control.

Databases, on the other hand, function completely based on the centralized aspect. No traditional database is powered by decentralization. If you are specifically looking for a decentralized database, then blockchain falls directly into the category.

Now you know about the difference between blockchain vs centralized database.

Authority in Centralized Database

Let’s take a deeper look into how centralization works in databases. An administrator is allocated to manage the database. The administrator has all the control over the database, which means that he can manage, modify, and control the database the way he wants. Without an administrator, the database will not function at all.

He is at the top and can easily create, modify, change, and delete the records. Other than that, they can also perform other tasks, such as performance optimization. It is an important task as a larger database tends to get slow over time.

When it comes to other users associated with the database, an admin can delegate roles to other users. Other users can manage the database according to the role that they are assigned. For example, he can assign a user to create new users. Other key functions, such as backing up the database, maintenance, etc., can also be done.

However, it is not simple when we take into consideration the different types of blockchains out there. The basic blockchain introduced in bitcoin is completely decentralized, but it cannot be implemented among businesses with private data and processes at stake.

That’s why blockchain evolved, and we have a different type of blockchain. Hybrid/Federated blockchain is the most common type of blockchain out there that solves the problem of private organizations.

Hybrid blockchains are permissioned, which gives organizations the full ability to customize their setup according to the requirement.

This is one of the biggest differences when we do private blockchain vs database. We will cover more about hybrid/private blockchain later in the article.

Blockchain Database vs Traditional Database: Architecture

Architecturally, both blockchain and database are different. So, what is the difference between the blockchain database structure and the traditional database structure? Let’s find out. You can a

A database is based on client/server architecture. It is a highly successful architecture that can work in both small-scale and large-scale environments. Here the client is the receivers, whereas the servers act as a centralized processing unit. The communication between client and servers are maintained through a secure connection.

Blockchain, on the other hand, uses a distributed ledger network architecture. It is a peer-to-peer enabled network where each peer can connect with another using secure cryptographic protocols. As there is no centralized node, nodes can collectively take part in the consensus algorithm.

One of the most popular consensus algorithms is Proof-of-Work, which requires miners to solve complex mathematical equations to validate transactions over the network.

The database doesn’t require a consensus algorithm and is completely dependent on the centralized approach.

The administrator controls every aspect of the database and is highly centralized. It is also permissioned like hybrid blockchain, but not when compared to the public blockchain. This hopefully answers your question related to permissioned blockchain vs database. The table below also covers permissioned blockchain vs database. Now you what’s the difference between blockchain database vs traditional database.

Performance	Extremely fast	Slow to medium	Slow

Blockchain Vs Database: Immutability and Data Handling

When it comes to data storage and handling, both blockchain and database work differently. In a traditional database, data can be stored and retrieved with ease. To ensure proper operation of the application, CRUD is utilized at the primary level.

CRUD stands for Create, Read, Update, and Delete. This also means that data can be erased and replaced with new values if needed.

Blockchain, on the other hand, works differently when it comes to data storage. Blockchain supports immutability, which means that data once is written cannot be erased or replaced. Immutability means that no data tampering is possible within the network.

Traditional databases don’t exhibit immutability and hence are more prone to being manipulated by a rogue administrator or third-party hacks.

In short, blockchain only supports two operations, Read and Write.

• Read Operations: Used to read or retrieve data from the blockchain network
• Write Operations: Used to add information and data to the blockchain network

Database Vs Blockchain Technology: Transparency

Another key property that blockchain offers is how anyone with the right tool can verify the data once written into the public blockchain. Transparency ensures that the public can trust the network.

Databases, on the other hand, being centralized, doesn’t support any form of transparency. Users cannot verify the information if they want to. However, an administrator can make a set of data public, but still, the data verification cannot be done by an individual.

Blockchain’s integrity is made possible thanks to the immutability it has to offer. Data, once stored cannot be corrupted or changed in any possible way, which means that the data integrity is maintained at any cost.

Blockchain Technology vs Database: Cost and Talent Acquisition

When it comes to implementation cost, a traditional database is less costly when compared to the blockchain. Blockchain is a fairly new technology and hence is still evolving.

This also means that a business needs to do proper planning and execution to integrate blockchain into their process.

Also, any business that is already operating needs to adopt new technology. The change in approach is a serious business as blockchain requires end-to-end implementation and cannot be just integrated into an existing system as an add-on.

The traditional database is easy to set up and scale. They work with most of the existing processes and hence work out of the box on many systems. This makes it an excellent choice for businesses who want to quickly and cost-effectively want to set up their database systems.

However, if we look at a longer look at the cost associated with each technology, blockchain might provide a more cost-effective solution as peers mostly manage the network. Organizations don’t have to deal with the extra cost associated with handling the network, which can save a lot of costs.

The same cannot be said when it comes to talent acquisition. Blockchain is fairly a new technology, which also means that there is a limited amount of talent available to deal with the practical blockchain applications. The cost of the blockchain talent is also high, which can increase the cost associated with the implementation and maintenance of blockchain on the higher side.

Database related talent, on the other hand, is easy to get. They are also affordable, and even small business can afford the cost of hiring a database expert.

Read More: Blockchain Vs Relational Database: What’s the Difference?

Blockchain vs Database: Speed and Performance

The speed of execution is also a critical aspect that we need to compare both blockchain and database. Databases are known for faster execution time and can also handle millions of data at any given time.

Blockchain is considerably slower when compared to databases. However, it can be because blockchain is a relatively new technology and still needs a lot of time to evolve and match up to the standards of well-aged technologies such as databases.

When a transaction is carried out in the blockchain, it does all the things that a traditional database will do. However, it is slowed down because of carrying more operations, including the following.

Signature Verification:

Blockchain transactions, when carried out, are cryptographically signed using cryptographic algorithms. This step is needed to ensure that each transaction is valid and originated from a valid source. As it is a complex process, it takes time to carry out the process. Even though the whole blockchain application is fast, the signature verification can bottleneck. In comparison, a centralized database doesn’t have to go through the signature verification process, which makes them comparatively faster.

Consensus Mechanisms:

As blockchain is decentralized, it relies heavily on a consensus mechanism to validate transactions on to the blockchain. Also, the speed of consensus depends on the type of consensus method used. Some consensus method is faster than others, but overall, it adds more time before a transaction can be processed. Centralized databases don’t suffer from this kind of issue as they are centralized in nature. Each transaction is verified automatically by the database and can be executed way faster using a queue.

Redundancy:

Blockchain is a complete network where each node plays a crucial role. To ensure that each node can participate, each transaction information needs to be stored and verified by each node.

These three aspects slow down the blockchain. This means that databases are comparatively faster when it comes to performance.

Blockchain vs Database: Best Use Cases

Now that we have understood some crucial differences between blockchain and databases, it is now time we learn the best use cases for both of them.

Databases Use Cases

The best use case for databases is enterprise solutions or networks. The reason behind it is how the database operates and bring stability to the whole network.

Databases are undoubtedly user-friendly and are already supported by many popular management systems for developers and administrators. Even websites with millions of visitors rely on databases to serve content. Forbes, for example, uses a database in conjunction with high-end systems.

The scalability is what makes databases such a good choice for the enterprises out there. Also, systems such as stock exchanges that rely on fast operations must use databases for better data flow. However, blockchain also seems to do great in enterprise networks.

The blockchain is not ideal for storing a huge amount of numerical data that needs to be regularly used. Another benefit is how data is stored in a database. It doesn’t have to go through verification during the write or read process. What makes the database a great choice is how cost-effective it can be, especially if there is a need to do basic bookkeeping.

To sum it up, the best use cases for the database include the following.

• Apps or systems that utilize the continuous flow of data.
• Storing confidential information
• Online transaction processing that needs to be fast
• Apps or systems where data verification is not needed.
• Relational data
• Standalone apps

Blockchain Use Cases

Blockchain’s purpose is completely different. It is a peer-to-peer network that establishes two important things to its users, i.e., transparency and trust. The distributed ledger is what makes it unique. It can change how an industry works and enhance every single aspect of it. So, what are the best use cases for blockchain? Let’s explore.

Any system that requires proper verification can utilize blockchain. For example, B2B Business-to-Business transactions can benefit immensely.

This includes supply chain, inventory management, and distribution. The key here is transparency as it enables businesses to follow every single movement without introducing more complexity. However, blockchain doesn’t scale that much and can slow down systems when handling large scale data records.

Another excellent use case of blockchain is permissioned networks. Permissioned networks such as voting can benefit from a decentralized approach and bring trust and transparency to the whole voting system.

Blockchain is also ideal for automating tasks within a platform. Smart contracts are introduced in the Ethereum blockchain, which brings in the ability to utilize stored procedures. If a certain condition is met, the code is automatically executed.

Ethereum blockchain also uses Proof of Stake (PoS), which is more efficient and less power-hungry.

To sum it up, the best use cases for blockchain include the following:

• Transfer value
• Storage value
• Monetary transactions
• Trusted data verification
• Voting systems
• Decentralized apps (dApps)

Concluding Thoughts: Which One Should You Choose?

The choice of picking up your next data storage technology is not a tough one. We discussed the crucial difference between them, and both traditional databases and blockchain are the clear winners.

The database is a winner when it comes to utility, speed, and accuracy. However, blockchain is also a winner when it comes to innovation, verification, and automation.

Blockchain introduces a performance penalty because of its verification method. This clearly means that you should avoid blockchain where fast execution time is an essential factor. Databases are a great choice where the critical business process needs to be supported or scaled at the same time. The read and write process is also not simple when it comes to the blockchain, which makes the database more desirable for general purpose application.

In short, choose blockchain if you are looking for trust, transparency, and verification. Database, on the other hand, is ideal for high-performance apps or services. It is also an excellent choice for apps that require scalability. If you want to understand blockchain more thoroughly, you should check out our free blockchain course now!

Chapter-1: What Is Blockchain Technology?

Let’s start with the most basic question of all time – “What is definition of blockchain technology?” Well, blockchain technology is a distributed ledger system that promotes decentralization, transparency, and data integrity.

Please include attribution to 101blockchains.com with this graphic. <a href='https://101blockchains.com/blockchain-infographics/'> <img src='https://101blockchains.com/wp-content/uploads/2019/07/Blockchain-technology-explained.jpg' alt='Blockchain technology explained='0' /> </a>

Does it seem confusing?

Let me explain blockchain technology in a simple way. Imagine multiple blocks that are connected in a chain-like a format. Here, all the blocks will be linked to the previous block and the block in front of it.

Moreover, all the blocks in that chain contain some form of data, and the chain represents the linking structure. In reality, every single block will link using the cryptography. Moreover, all the blocks in that chain will have a cryptographic hash ID along with transactional data and timestamps.

And so you end with a growing chain of blocks, and that is my friend what a blockchain is. You could think of it as a database that stores information in a unique way. But blockchain and databases are practically quite different in nature even though they both store information.

By default, blockchain technology does not support any modification of the data. So, any data that would go in the block can never get deleted or altered. Thus, it will stay there forever. Another significant fact about blockchain technology explained is that the network is a peer-to-peer network.

So, there is no centralized connection lurking in the shadows trying to steal your information. I mean, who wouldn’t like this much freedom, right?

Blockchain Technology Explained: How Does It Work?

Well, it’s time for you to know how the tech actually works in this blockchain guide. But before we begin, take a look at some of the important features to know about beforehand.

Blockchain stored all the information in a ledger system. Moreover, any kind of data exchanges is called “transactions.” Previously blockchain was only meant for transacting digital currencies, but now it can even use other forms of data as well.

Every single user on the network is called “nodes,” and they get a copy of the updated ledger. Moreover, every node has a different way of communicating with each other. The system varies from blockchain to blockchain.

Now let’s begin the explanation of blockchain technology!

First of all, a user will request for a transaction in the network. Here, he/she will get two keys – public and private. But the user can only transact using the private key. And to find the other person you are sending money to you will need their public key.

Anyhow, after the request a block with all the information of the transaction gets created. In reality, everything in the block is encrypted to promote security.

Once it’s created, it will be broadcasted to all the nodes in the network. In blockchain technology explained you need verification from other nodes that what you claimed is valid. And so the other nodes use a consensus algorithm (I’ll explain what it is a bit later) to validate the information.

Once your block gets validated, the block will get a spot on the chain. At the same time, the transaction you did will be executed as well.

Understanding how it works doesn’t seem that much difficult now, does it?

Chapter-2: Layers of Blockchain Technology

Now let’s talk about the different layers of the blockchain technology in this explanation of blockchain guide. Primarily there are 5 different layers of the tech, and we’ll get to every single one of them here.

So, let’s start.

1. Application Layer

At first, let’s talk about the application layer. In reality, it comes with dApps, dApp browser, User interface, and the application hosting.

Using the dApp browser, you can get access to the decentralized applications. Unfortunately, typical browsers like Chrome or Firefox isn’t capable of browsing through decentralized applications. So, in this one, you will get a completely different user interface similar to typical browsers.

However, with these, you can also surf the regular internet.

Next, the application hosting lets you run all the decentralized application in this layer. Without this element, no dApps can be live on the internet. Obviously, the hosting protocol will be fully decentralized as well. Moreover, maintaining these hosting servers are absolutely secure as they have a low risk.

Next comes the decentralized applications. Typically these are similar to today’s application but with one distinct change. All of them have a decentralized network. Furthermore, these are extremely easy to make nowadays.

2. Services Layer

This is the second layer after the application layer. In this one, you’ll get access to all the essential tools that will help you build and run the dApps layer. In reality, in this blockchain explained layer, it covers all the vital elements.

More so, you’ll get your hands on governance, off-chain computing, state channels, data feeds, and side chains.

Data feeds are a process that helps to get the most updated information from all the credible sources. So, it will help the nodes to get the latest updates information about the network.

On the other hand, off-chain computing is here to get the computing process done outside the blockchain. Furthermore, it promotes additional privacy and takes the burned off the core network system.

Additionally, you’ll get a governance structure here as well. In reality, these are basically a human-less autonomous organization that can promote a fair environment.

Furthermore, the state channel actual is the pathway between two nodes. So, using state channels, two nodes can communicate with each other.

Other than these, there are also other elements in blockchain explained layers. Mainly these are Oracles, Multi-signatures, Smart contracts, Digital Assets, Wallets, Distributed file storages, Digital identities, etc.

These are optional because a blockchain technology may have it or not.

Oracles:

Oracles are necessary for smart contracts because they act as an agent for collecting information from outside the network.

Multi-signatures:

This element ensures a different kind of security protocol. In reality, you would need to sign any transaction without a unique signature for making a transaction. And here, you can choose how many of these signatures you want for transacting.

Smart contracts:

These are mainly self-executing legal contracts within two participants on the blockchain technology network. In reality, the whole system gets rid of the trust issue and lets you quickly exchange any kind of asset.

But we will get to it later in the blockchain guide.

Digital Assets:

Now on the blockchain technology stack, the digital asset can refer to anything. In reality, it can mean cryptocurrencies, shares, gold, or even other kinds of document. Furthermore, any digital element with real values in the real world would be known as digital assets.

Wallets:

Here, in the blockchain technology wallets are to store all the digital assets you will have on the network.

Distributed file storage:

In the explanation of blockchain technology, I can safely say that distributed file storages are actually a server location where all the data will be stored. Obviously, you’ll need authentication for accessing them.

Digital Identity:

In reality, Digital Identities are the identities of the users on the network. Furthermore, you will need it to have proper authentication on the network.

Let’s move on to the next layer in this blockchain explained guide.

3. Semantic Layer

In this layer, there are consensus algorithms, virtual machines, any kind of participation requirements, and so on.

There’s no blockchain network without consensus algorithms. In reality, consensus algorithms are absolutely necessary for maintaining an agreement between all the nodes. Practically, it’s a process where all the nodes come to the same agreement over the information on the ledger.

Furthermore, in the ledger, no one can just start a transaction and get it added. He/she may not be honest as well. So, to make sure that the information on the block is valid, all the nodes come to the same agreement. But we’ll talk more about it later in the blockchain explained guide.

Next comes the participation requirements. In reality, these are mainly rules that helps the network decide who can join the system and who can’t. Moreover, this element is basically for the private blockchain technologies out there.

On the other hand, virtual machines offer security and execution environment for all the tasks on the network.

Mostly, it’s used in the smart contract execution. Next comes the side chains where developers can go to another separated blockchain environment to develop decentralized applications without affecting the core network.

Anyhow, let’s move on to the next layer in the explanation of blockchain technology guide.

4. Network Layer

Another layer after the semantic is the network layer. It contains Trusted Execution Environment (TEE), Roll your own mechanism, RLPx, Block delivery network, and many more.

Basically trusted execution environment helps the architecture to maintain scalability issues. Not only it helps the network overcome this issue, but it also makes it more secure. Furthermore, it helps to store data away from the main network to take some of the loads off it.

Usually, these protocols are for when a standard protocol doesn’t fully adjust to the infrastructure. So, it lets you customize other protocols to better adapt to it. It’s best to work with standard ones. But in some cases, the standard might not be enough.

On the other hand, RLPx is a network suite that helps in the transportation of data between two peers. Anyhow, it creates an interface to help the users communicate in the blockchain network.

Lastly block delivery networks is a network system that will deliver a web content or page to you if you request for it. In reality, you can see it in the typical internet architecture.

But if you are working on a decentralized application you will need some kind of delivery system to access web content, won’t you?

Now let’s move on to the next layer in this explanation of blockchain technology.

5. Infrastructure Layer

This is the last layer in the blockchain technology architecture. In this one, you might come across mining as a service protocol. However, now, mining is slowly going away because of the excess power it needs.

On the other hand, virtualization is the means of creating any kind of virtual resources such as servers, network, storage, OS, etc. Furthermore, it operates in three levels – hardware, system, and server. Nodes are also a part of this layer. Any device connected to the network is considered a node.

In reality, without any nodes practically, there won’t be any blockchain technology at all. Another cool element of this layer is the decentralized storage of the network. As it’s decentralized, it’s more secure than ever.

In reality, you might see token on this layer as well. Tokens help maintain the ecosystem and are a native asset on the network.

So, these are the five layers of blockchain technology. Now let’s move on the next phase of this explain blockchain technology guide.

Chapter-3: What Are Smart Contracts?

Now let’s talk about one of the significant features of the blockchain technology in this explain blockchain technology guide. Previously you got a little bit of introduction to the smart contracts. But now we’ll dive into a bit deeper into this topic.

The usual definition would be –

Smart contracts are self-executing legal contracts within two participants on the blockchain network.

Typically with the smart contract, you can practically exchange any kind of asset such as money, property, shares, anything that is deemed valuable. Moreover, it lets you do it securely and transparently. Furthermore, in smart contracts, there’s no need for any intermediary.

Now there are many blockchain applications that come with smart contracts integration.

Thus, this is the main difference between the typical contracts. In case of any legal contracts, you would need to pay for the service and then get that in return.

However, here you won’t have to wait for the service to get done after paying for it. So, there’s no issue with trust at all. So, it’s kind of like a vending machine, where you can get candy or snacks right after the paying.

To help you better understand what the situation is, I’ll explain how it actually works in this explain blockchain technology guide.

How Does It Work?

First of all, a party creates a contract after the full agreement from two or more parties. When the contract is created, all the parties can choose to remain anonymous. In the typical private network space, mainly you would have to have a proper authentication process to enter the system.

So, when someone starts a smart contract with you, they will most probably know your identification as well. Well, at least you’d have to let them know about the public address.

After that, the parties would set any kind of rules that needs to be fulfilled in order for the contract to be valid. It could be anything or any triggering event. So, when that condition would be made, it’ll automatically trigger the next event.

Once everything gets set up, it’ll get verified and stored on the ledger. After that, everyone connected to that contract would be able to see the progress right from the network. Moreover, in case of tracking everything will be in real-time.

After fulfilling all the conditions to fulfill the contract, it’ll self-execute and distribute the money.

Basically, it’s a great way to automate the process of ay contract. As everything is automated and tracked right from the UI, it saves a lot of money and time.

Why Is Smart Contract So Beneficial?

Another important fact I should explain in this explain blockchain technology guide is that smart contracts highly beneficial. But why? Well, let’s find out.

• No Interruption: Due to getting rid of the middleman, there’s no annoying interruption time in the process.
• High Security: You can see everything right from the blockchain applications UI, so there’s no way anyone can scam you as you can just what the process is. Also, no one can hack the data on the smart contract to alter the outcome.
• Quite Fast: Typically processing everything manually takes up a lot of time. But when it’s on the blockchain applications network, it’ll flow quite fast.
• No human Error: Practically in many contracts, the human-made error cost a lot of money and time. But with this blockchain applications digital contract, the chance for that is entirely low.
• More Profit: In reality, getting rid of the intermediary gets rid of the extra payment option as well. So, that means more profit for you.

So, these are the advantages of smart contracts. Let’s move on the next phase of these basics of blockchain technology guide.

Chapter-4: Different Consensus Algorithms

• Proof of Work

Proof of Work is the first-ever consensus algorithm in the blockchain network. As you know, bitcoin had the first working blockchain network, and it used proof of work. After that, many other blockchain networks use this method until now.

However, proof of work consumes a lot of power and is relatively slow. In this one, miner tends to solve complex mathematical problems using their devices computational power. Basically, it’s for verifying every single block on the chain.

Let’s move on to the next algorithms in the basics of blockchain technology guide.

• Delayed Proof of Work

This is another version of the proof of work algorithm. You could think of it as a hybrid model. In reality, this one allows the network to take advantage of the power of hashing from another blockchain network.

But how? Well, some notary nodes add data from the first blockchain to the second one, thus securing the power. Any blockchain network working on the dPoW can use either PoS or PoW to function properly. Anyhow, this one is much faster than the original proof of work.

• Proof of Stake

Proof of stake actually came because of the limitations of the proof of work. Here, every single block will be validated before any other block comes along. Moreover, the miners here can stake their coins and take part in the process.

But here the taking participation would depend mostly on the possession of coins. So, if you have a minimum amount of coin, you can take part or else you can’t. In reality, proof of stake is much faster and less power consuming than PoW.

• Delegated Proof of Stake

This is another variation of the proof of stake algorithm. In reality, this one is much more robust and flexible than other algorithms so far. Furthermore, all the nodes here are delegates. There’s also a concept of witnesses that are selected through voting. After they validate each node, they get paid accordingly. Also, the delegates are chosen using voting as well. And mainly these nodes are responsible for changing the parameters of the system.

However, they do not get paid the same as the witnesses. Anyhow, let’s move on to the next one in the basics of blockchain technology guide.

• Leased Proof of Stake

Leased proof of stake is yet another entry in the basics of blockchain technology. In reality, the Waves uses this consensus algorithm. Furthermore, the process limits the use of power in any way possible.

Here, smallholders can lease their coin to the network and take part in the consensus process. So, there’s no issue of unfair rules in this one. As the small coin holders never got a chance in the previous PoS algorithms, here, the full transparency prevails.

• Proof of Stake Velocity

Proof of stake velocity is a relatively new addition to the basics of blockchain technology. At present, Redcoin uses this method to validate a block. Here, the process encourages you to have both ownership and activity in the network. These are mainly two functions of this new coin.

In reality, the coin mainly facilitates social interactions in the digital world. However, it’s more power-efficient and fats than typical PoW and PoS.

• Proof of Elapsed Time

It’s a great consensus algorithm for blockchain applications. However, this one is mainly suited for a permissioned type blockchain network. So, basically not suitable for the public ones. In reality, all the individuals have to wait for a certain amount of time to join a consensus. The time limit is randomly chosen.

Once they finish the wait time, they can then create a block. However, to make sure that the winner chooses the random number, everything is monitored that way.

Moreover, it’s also tracking that if the user did wait for the time, he/she was supposed to.

• Practical Byzantine Fault Tolerance

Another great consensus algorithm for the blockchain applications. In reality, it mostly depends on the state machine. Even though it follows the same method as Byzantine but still manages to get rid of the general issue.

Before anything happens, the system assumes the possibility of failure and uses other nodes to manage that. Usually, all the nodes in the system are specifically organized. And all the nodes within the network work in a harmony and relay information super-fast.

So, even if a node gets compromised, all the other nodes will know about it quite soon.

• Simplified Byzantine Fault Tolerance

In the simplified Byzantine fault tolerance algorithm, a group of transactions gets validated at the same time. Usually, the block generator, in this case, collects all the transactions at a time and then batches them accordingly. After grouping them, they get into another block and then that block gets verified.

Before validating any big block, the generator will declare all the rules for the nodes to follow. After that, a block signer uses his/her own signature to validate them. And so, if any of the blocks don’t come with the key, it would get rejected.

• Delegated Byzantine Fault Tolerance

In this one, the power of the general is limited drastically. While choosing a leader for the army of nodes, the leader would get called the delegate. In any case, if the general tries to be corrupt, another delegate replaces that one.

More so, even the army of nodes can disagree on the leader and can choose another one. SO, as the general would have no sole power, other parties can’t corrupt that node. Moreover, all the nodes may choose a speaker to relay their messages to the delegate.

In reality, to pass a new motion, at least 66% of all the selected delegates would need to agree with the motion.

• Federated Byzantine Agreement

It’s a rather latest addition to the Byzantine algorithm family. Mainly you will see this one in a network where the transactional costs are pretty low with high scalability and throughput. Moreover, here all the general would get their very own blockchain.

At present, only Ripple and Steller use this method to validate the blocks. However, before any node can request for performance that nodes need to be verified form beforehand. So, the nodes will only choose them that they really trust in this case.

• Directed Acyclic Graphs

At present, IOTA and NXT use directed acyclic graphs in their blockchain network. Even though many people consider it as a consensus algorithm, in reality, it’s not entirely that. It’s actually a form of data structure.

Furthermore, the data is in topological order other than being in a chain-like format. So, instead of getting one single chain, DAG actually has multiple side chains. Thus, it can validate multiple transactions at a time in parallel. That’s why it takes less time than usual consensus algorithms.

• Proof of Activity

Proof of activity uses both proof of work and proof of stake to make another hybrid algorithms model. So, the system becomes more robust against any kind of attacks and also uses less power. In reality, the miner mine blocks that are templates rather than complete block.

Furthermore, the block then indicates to a stakeholder that later validates the remaining pre-mined block. Also, the more stake a validator will have, the more valid will his verification be.

At last, all the miners and validators get a fair share of payment from the network.

• Proof of Authority

Well, this is one of the energy-efficient consensus algorithms on the list right now. However, it suits a private network better than public ones. In reality, only some of the approved accounts can join the validation process.

More so, these nodes are previously approved to be validators. Anyhow a node has to earn the right to validate other blocks and also needs to leave their computer untouched. For doing so, they get rewards on the network to maintain their authority.

• Proof of Reputation

Another consensus protocol that more suitable for permissioned networks rather than public ones. Usually, in this case, the nodes need to have a good reputational strength to participate in the process. Additionally, the nodes will face severe consequences if he/she tries to cheat in the validation process.

So, not all the nodes can really take part in it. Once the node earns a reputation, then the process is quite similar to the proof of authority.

• Proof of History

I think you already know how the validation process heavily depends on eth timestamp. But here, you can prove a transaction based on what happened before or after that. So, to do so, you can create a significant event in time that will occur before or after any specific time on the network.

And based on that, others can validate your transaction block. Thus, by doing so, you don’t even need the information of the timestamps in the block.

• Proof of Importance

Next is proof of the importance consensus algorithm. In reality, it depends on a new factor called vesting or harvesting.

Due to the harvesting, it can determine if a node is eligible to participate or not. So, the more you harvest, the more the chance for the node to become a validator. Also, for the harvesting, the validator gets a reward as the transactional fee. However, the wealthy on the network would have more chance of getting a spot than others.

• Proof of Capacity

Here, they use the plotting and mining to finish a validation of blocks. Many people also use it instead of proof of work because in this one it takes less time than that. But in PoW you would have to use your computational power even before you start mining.

Even though it’s pretty fast, still, it takes four minutes to mine a block. But I guess you get a six-minute boost. Anyhow, the more plots you have on your computer, the more chance for you to be the mining winner.

• Proof of Burn

In proof of burn, you would have to burn some of the coins to safeguard the crypto on the network. Obviously, burning the coins would mean a loss. But in the long run, it will keep the network stable. To burn coins, the users will send some of their coins to an eater address.

To make sure everything is in check, the ledger keeps track of all the coins and makes sure they are not usable.

• Proof of Weight

Proof of weight is actually a massive upgrade form the proof of stake algorithm. Usually, in proof of stake, you see that the more tokens you have, the higher chance of you getting more. In reality, this is a bit biased.

Instead of only taking the tokens into account, the network uses other factors to weigh in. Moreover, these factors are actually the weighted factors that help to determine which nodes get to participate in the system. In short, you get more scalability and faster output here.

Chapter-5: Web3: The New Internet

Understanding blockchain technology is easier than you think. Previously we talked about the layers of the blockchain technology. However, this architecture will actually fuel the next generation of the internet.

Usually, it comes with some of the critical elements that we will see.

Now we will talk more about it for understanding blockchain technology a bit better.

Let’s start!

• Artificial Intelligence

Well, first of all, this is definitely not about super robots. In reality, the AI will ensure a better output when it comes to results and analysis of the data on the ledger. Even though it might not sound like a big deal, but the experience will drastically change.

Typically it will make sure that you get to the content that you are looking for on the internet. So, that means more accurate results, better forecasting of your actions. In reality, it’s just a simple mechanism that helps to learn about your tastes and give you’re the best output base do that.

• Ubiquity

For understanding blockchain technology better, you would need to know what the ubiquity is really about. Just look around you and see what all the people are using any kind of device to use the internet.

Moreover, all the smart TV, fridge, smart home accessories, assistants, tabs, or smartphones do the same thing. So, they all connect to the internet. By doing so, they form a network. Usually, this network is actually called the Internet of Things. However, in some cases, people call it ubiquity.

Anyhow, the future of the internet depends a lot on this process.

• Enhanced Connectivity

The new internet web 3.0 is based on the fact that it would be user-centric. So, it means that you will see more connectivity than you see in web 2.0 internet. Additionally, no one will control your data or use it for their personal gain.

Here, the semantic metadata is of big help. In reality, it helps the users to stay connected more easily and quickly. Thus, it enhances connectivity.

• Semantic Web

For understanding blockchain technology, you need to know about the semantic web as well. It’s a massive part of the web 3.0 internet. Furthermore, semantic web actually means the understanding process of any web content similar to humans.

Thus, it will depend on machine learning and will not focus on keywords only. So, if you have good content and do not depend on the keywords, you are going to have a good amount of crowd.

• 3D Graphics

Well, obviously 3D graphics are a huge part of understanding blockchain technology web 3.0. As you can see now, people like to see images, videos instead of reading any texts. So, the best way to increase focus would be to have 3D graphics integrated to it.

All the apps in the future will use some form of Virtual Reality or Augmented reality

• Peer-To-Peer Network

The new internet will be totally decentralized. So, there is no option for any kind of centralized authority ruling over what you do and what you don’t. But that clearly doesn’t mean that you can break all the laws here.

This is just an element that will ensure all your data online will remain safe no matter what.

Before we dissect why blockchain will change the world, let’s begin with “what is blockchain.” Blockchain technology is a distributed and decentralized ledger system that offers transparency, immutability, and security.

Judging from the last few years of success, blockchain is here to stay and is slowly disrupting various industries. But don’t worry, disruption doesn’t always mean a negative impact. In reality, blockchain can help out in all the industries, getting rid of the flaws that plagued them in the first place.

So, any novice who isn’t familiar with the topic should use this guide to get familiar with the concept of blockchain and how it will change the world.

How Will Blockchain Change the World?

Now that you know what blockchain is, we can move to how it can actually alter the course of our economy and business.

The blockchain is a decentralized database where all the transactions are stored and validated that has value. However, the value can represent anything at all, like money, lands, jewels, etc. Forbes is already seeing the future and putting its faith in the new money. They believe blockchain will change the world.

But first, what kind of benefit does it beget? And how will it change the world?

Peer-to-Peer Network System

Everybody has complete trust in the blockchain database as it’s not governed by any single organization, meaning it’s open. With blockchain technology, you can transact directly to its receiver, which indulges any third party.

Thus, it completely makes them pointless as you don’t need any other third party to validate any more. So, the impact of blockchain here is establishing peer-to-peer transactions rather than a client-server model.

No Centralized Control

Blockchain will change the world by getting rid of centralized control. No central authority can control your assets anymore. Although the public blockchain system is autonomous, a private blockchain system does need authentication to function. But it still can reduce the level of centralized control.

Over the past years, we have been seeing the unimaginable dominance of Google, Facebook, or Amazon in the market. Now they have the personal data of almost everyone in the world! However, blockchain can help you take back control of your own data.

Improving Privacy

Using the hash function and cryptography method, all the transactions are encrypted, and none can keep track of your transactions. In reality, this really helps to maintain privacy as no bad party can see the contents of your transaction even if they want to.

Full Transparency

One of the best parts about blockchain is that it promotes transparency. At present, most of our business models don’t offer this attribute. We can’t even get transparency from the government itself.

So, when blockchain offers a public ledger system where everyone can see what is happening, it can restore people’s lost trust.

No Corruption

Blockchain will change the world by getting rid of corruption in our society. In reality, as we are still operating on legacy network systems and paper-based documents, it’s easy for fraudulent parties to alter them.

But blockchains are completely immutable by nature. It’s impossible to alter or change contents inside a block. If someone tries to tamper with it, all the nodes in the system will reject it instantly as it violates the consensus. Thus, it gets rid of corruption.

Blockchain Changing the Economy: New Monetary System

Another new feature of blockchain is slowly getting traction at the moment. It’s the change in the monetary system from centralized to decentralized. At the moment, many governments are interested in central bank digital currency models.

In the traditional method, the third party is the federal banks who issue “money,” which is a valuable entity in our consideration. But the federal banks don’t share their records with the public and controls the overall economy.

Moreover, transactions are often unreliable. As a result, financial fraud cases occur.

The problem doesn’t end here. Each country has a different currency of its own. So, there is no unified currency. People have to go through troublesome hurdles before they can use their money in a foreign land. Transactions take days.

Plus, the “all-seeing-eye of government” keeps track of every single penny you spend. Who wants someone to nosing his business? It’s a breach of someone’s privacy.

But with the invention of the CBDC model, now many countries are adopting blockchain and making a digital copy of their native money. Countries like China or the USA are already developing their solutions.

This will definitely change our social and economic status for good.

China is recently launching its very own CBDC model. Learn more about it from our guide on the DCEP project.

When Will Blockchain Take Over?

If you are thinking about when blockchain will take over, you need to know that it’s already taken over many industries. Like supply chain, trade finance, insurance, and healthcare, many industries are adopting blockchain technology for their companies.

So, change has already begun. However, only when blockchain can get rid of its technical flaws can it start the mass adoption process.

Why Blockchain Will Change the World?

Well, we think it’s important to note down that blockchain will not only change the technological aspect of the world, but it will also affect the ways we function as a society. More so, blockchain is the change of paradigm, a way we can understand the world as a whole and not only parts of it.

How will blockchain affect the economy? The traditional ways are full of issues and, most of all, corruption. So, it was high time for us to adopt a technology that helps us to make our business models even more efficient. This is how blockchain can positively affect our economy.

Will blockchain succeed? We believe so! It is already showing positive outcomes in many projects. Also, many enterprise companies are investing a good deal into blockchain-based solutions. Therefore, the shift is not only beneficial for the people but for the companies too.

Ending Note

Blockchain growth has been rampant in the past few years. You’ll see a lot of Blockchain applications recently. You can buy cars, homes, to healthcare services with cryptocurrencies now. Considering its ever-growing popularity, it can be simply assumed that blockchain will be the future as it solves every single problem the traditional systems have.

However, only time can tell us whether blockchain is suited for our future or not.

Most importantly, how it will really affect the world once it’s adopted worldwide. If you are just a novice in the blockchain realm and want to learn more about this technology, you can use our free blockchain course for it.

Blockchain is predicted to the technology of the future, so why would you stay behind the race?

Let’s start with a question — How does blockchain technology work? Basically, a blockchain is a series of blocks containing data and which has a hash number and a hash number of the previous block.

On a technical level, you can say the same thing about a linked list! It is a type of data structure that ‘stores data’. That being said, what are the main differences between these two types of data storing tools?

For those who are not so adept in the language of computer science, terms like data structure would hold no meaning. It’s quite normal for people who don’t have primary knowledge of computer science.

What is a Linked List?

A linked list is a linear way to organize and store data where every single element represents a different object. You could call it a series of data of various types. In computer science’s language, a linked list is a data structure.

In a linked list there is a sequence. Each data element has a “pointer” assigned. Meaning, you could always trace the previous node of the list. Thus, the whole list works like a chain. By following the hash number, you could even reach the genesis node.

There is an interesting fact about it, you can find the parent node linking in the blockchain technology too. This is a key feature that makes the blockchains immutable. Once it is designed, it’s done!

What is Blockchain and How Is Blockchain Similar to a Linked List?

You must be already getting the idea of how these two have some noticeable similarities. The blockchain data structure can easily be said to be a linked list. While the linked list has the pointer function, the blockchain has the hash function. Each block in the blockchain has a unique hash number as well as the hash number of the previous block or the parent block.

Both blockchain and linked list adopt the same technology. They both have a genesis block that doesn’t have a previous hash number.

So yes, blockchain does actually share a few characteristics of a linked list data structure. You can check out the core blockchain features to learn more about the technology.

However, there are some fundamental differences between these two technologies, as well.

Blockchain vs Linked List: What are the Key Differences?

The first and foremost clash of blockchain vs linked list is that a blockchain has a hash function to identify the ancestor of a particular block. Whereas a linked list does the same function using a pointer function. Learn more about hashing in cryptography here. Also, if you want a more comprehensive knowledge, this detailed guide on cryptographic hashing should give you a vivid idea of how does hashing work.

Again, a blockchain is way more complicated in terms of structure. A linked list is a linear way of arranging and storing data.

Blockchains, for example, have Merkle Trees to store transactions and all the data related to the transactions. Moreover, these Merkle trees (or blocks) have a link to their parent hash with the unique hash number.

Moreover, a blockchain has some unique features. For instance, a blockchain is a decentralized, distributed, and autonomous digital ledger that can have numerous applications in our practical life. Data manipulation and tampering are nearly impossible as the system of the blockchain will allow it in sense. While on the other hand, a linked list is a simple way of structuring data.

How does the blockchain eliminate the risk of cyber-attacks?

Well, the copy of blockchains is distributed among the users within the network. So, everyone in the node is working as a validator. If someone tries to tamper with one copy, it will not sync with other ones. The other node will simply reject the unusual change. That’s how blockchain security safeguards against cyber-attacks and hackers.

A blockchain has the potential to create decentralized apps, decentralized organizations, a smart economy, and many more. Maybe the key definition of how blockchain functions raised the question of it being similar to the linked list.

Conclusions

So, that was a brief summary of the blockchain vs linked list debate.

Is blockchain a linked list?

NO!

A blockchain does possess some key characteristics of a linked list. But that’s it, essentially it is much more complex and has way more functionality. A linked list doesn’t have data validators who will safeguard the integrity of the linked list. Blockchain, on the other hand, is a fully functioning autonomous system.

The distributed ledger technology (DLT) is the backbone of blockchain technology. All blockchains inherently use a distributed ledger to function. In fact, blockchain is one of the technologies under the umbrella of distributed ledger technology.

Of course, distributed ledger technology is a complex technology and requires a deeper understanding of multiple concepts related to this technology. This article tries to offer a brief introduction to the concept of DLTs.

What is Distributed Ledger Technology?

Distributed ledger is a digital database that runs on a distributed network. It is spread over diverse locations, networks, and beyond boundaries. The main idea behind distributed ledger is that any central authority does not control it and hence offers transparency.

Each node of the network takes part in the distributed system. Each of them knows the ledger as they have an exact copy just like other nodes in the network.

The distributed ledger systems are extremely fast. It doesn’t take much time to reflect change across the network.

Distributed ledger technology is an excellent choice in this age of cyberattacks. With a distributed ledger, it becomes hard for hackers to hack the database. This is because everything is transparent and it is easy to trace back to the hacker. Also, to hack, the hacker needs substantial computational power which might be not possible for almost the majority of them out there.

Unique Features of a Distributed Ledger

By using distributed ledgers, there is no need for centralized authority. A distributed network is all about decentralization. It is a network of ledger or contracts that is maintained by nodes. The nodes can be merged into blocks which makes it even easier to maintain larger distributed network ledgers. Without the need for a central authority, all the information stays secure.

However, to enable the distributed network, technology such as cryptography is required. The data can be used with the help of cryptographic signatures and keys. For further study, you should learn more about hashing in cryptography.

Anything that is stored on the distributed ledger is immutable. This means that once stored; it cannot be changed. Immutability makes it even harder for hackers to try to hack the distributed ledger network. Furthermore, the absence of the central authority means that it is also free from any intentional change as well.

Blockchain vs Distributed Ledger Technology (DLT)

Someone who is still learning the fundamentals around blockchain technology often makes the mistake of thinking DLT and blockchain as the same technology. Rather than making things complicated, you can remember one simple thing —

Blockchain is a type of distributed ledger but every distributed ledger is not blockchain.

While blockchain has a particular block structure, DLTs are not bound to follow the same structure as the blockchains. Distributed ledgers can follow different data structures. The same thing can be said about following a data sequence.

Another big difference is that blockchains MUST need a power-hungry consensus algorithm to function. But distributed ledgers don’t need a consensus algorithm. That’s why distributed ledgers also are less power-hungry and more scalable.

The main reason why distributed ledger technology is so compelling is the fact that it can be used to power blockchain. The blockchain is a specialized database that uses DLTs.

Final Words

Distributed ledger technology is still in the infant stage, but that shouldn’t discourage companies to utilize it to make their business more effective. DLT is also incremental which means that it can be scaled easily. It can act as a cornerstone of future technologies and solutions that can make life easier for every one of us.

DLT solves a lot of problems that the current world is going through. Not only it is capable of storing essential data, but it also solves customer problems such as protection, integrity, speed, and so on. It also reduces the environmental footprint with the reduced use of paper.
