In this post, you'll learn What is Blockchain Size and How Does It Affect Blockchain-Based Projects?
Blockchain is known to revolutionize the world around us. After all, it changes how we define the process, store data, and explore the security of a network that the application runs on. It brings immutability, transparency, and unparalleled security that no other technology has been able to do so until now.
But there is one big problem — blockchain block size.
In any blockchain network, there is no centralized authority. Peers participate in bringing decentralization to the network. Each peer has a copy of the ledger (where all transactions are stored). This means that if any new transaction takes place, the ledger on each node will be updated accordingly. The unique solution lets businesses to create decentralized networks capable of solving problems not possible before.
Many of the industries are now implementing blockchain solutions to secure their place in the changing times. However, as other companies are eager to learn about blockchain, many are often confused over how blockchain works. Thus, because of the complex nature, even though many want to implement it, they are unable to fully grasp whether it would be a better option or not.
Blockchain being completely a new system does have a unique way to offer decentralization. That’s why in this guide of how does blockchain work will cover everything related to it. So, just grab a cup of coffee and let the reading begin!

Well, let’s start off with the basics. Before you jump into the process, you need to take note of these critical features of blockchain.
Blockchain will store any kind of data exchange on the platform. So, it’s like a ledger system, where every data exchange has a spot in the log. More so, the data exchanges in the system are called transactions. Once the transaction is verified, it gets a place in the ledger system as a block.
Once it gets on the ledger, no one can delete or alter it in any way.
In reality, blockchain uses a peer-to-peer distributed network, which will ensure the decentralized nature of the technology. Every device that connects to the network is considered a node. Also, to understand “how does blockchain work,” you need to understand the concept of “key.”
This is the basis of technology. Furthermore, the keys offer security on the network. For this, a user on the network will generate key pairs known as private and public keys.
Once you start using the keys, you end up with a unique credential that no one can get access to.
Anyhow, you’ll have to store the private key in a secure place because you’ll use this key to sign or perform any action on the network. On the other hand, other users will use your public key to find you on the system.
For example, imagine your public key as your bank account and private key as your signature that you can use to send or withdraw money. That’s why it’s necessary for you to keep the key as safe as possible.
In reality, if anyone gets access to your private key, they can easily misuse all your assets on the network.
Firstly, a user or a node will initiate a transaction signing it with its private key. Basically, the private key will generate a unique digital signature and make sure that no one can alter it. In reality, if anyone tries to modify the transaction information, the digital signature will change drastically, and no one will be able to verify it. Therefore, it will be dismissed.
After that, the transaction will get broadcasted to the verifying nodes. Basically, here, the blockchain platform can use different methods to verify whether the transaction is valid or not. There methods or algorithms are called consensus algorithm.
Anyhow, once the nodes verify that the transaction is authentic, it will get a place in the ledger. Also, it will contain a timestamp and a unique ID to secure it further from any alteration.
The block will then link up to the previous block, and then a new block will form a link with this block and so on. And this way, it creates a chain of blocks, thus the name blockchain.
Now, you know how does blockchain work, but is the working process secure enough to integrate into the enterprise environment? Well, there’s definitely no network on the internet that’s ‘unhackable.’ But blockchain does offer the highest level of security compared to any other technologies out there.
Blockchain works in a different method, not like the traditional centralized system. So, if you want to hack it, you would have to hack all the devices connected to it. Obviously, it’s a loss project and quite complicated, and that’s why it’s secured.
In reality, hackers would need a tremendous amount of resources to hack a blockchain platform, which will eventually be more costly than the gain itself.
You already know by now that consensus is a method of reaching an agreement. Basically, it’s a form of how individuals on the network can reach a resolution even though minorities may not like it.
In reality, the consensus is one of the core priorities of a blockchain because, without it, thousands of nodes can never come to an agreement. These models exist to create fairness and equality among all the participants.
However, there’s no one way to reach a consensus within a system. In reality, there are lots of algorithms that various blockchain platforms use. Obviously, every single one of them works differently and comes with its own set of flaws.
So, if you are wondering how does blockchain consensus work, you have to know about each one of them separately to understand.
It’s one of the popular and first consensus algorithms introduced in the blockchain. Here, nodes are called miners, and they will solve complex mathematical issues with help from their device’s computational power to verify the blocks.
Here, some notary nodes will add up data from one blockchain platform to another and secure the power of hashing. Both of the blockchain networks may use PoS or PoW to reach consensus.
Proof of stake allows you to take part in the consensus in terms of how much coins you staked in the network. If you have more coins, your possibility of mining a block will increase.
In this one, there’s a concept of delegates and witnesses. Each node is chosen using voting. Witnesses on the platform are responsible for validating the transactions. On the other hand, delegates can change the parameters of the system. Anyhow, all the nodes taking part in consensus will get paid.
In leased proof of stake, the smallholders can take part in consensus. As the previous PoS won’t let them stake their coins in the network, it creates an unfair environment. That’s why LPoS offers more fairground.
Proof of stake velocity offers an extra incentive to keep the users from staking into the network. Here, you can earn more if you maintain an active wallet. This means the users who aren’t active quite often won’t get the extra payment for validating a block.
All the nodes have to wait for a certain amount of time before they can participate in consensus. The time limit is chosen randomly. Thus, you can only create a block when you finish the wait time. There’s no way to bypass it, as the system tracks if the node waited or not.
Practical Byzantine Fault Tolerance gets rid of the compromised node issue. So, before any node can harm the network, it assumes the possibility of failure. In reality, the system gets information from other nodes as soon as a node is compromised to dismiss that node.
Here, the transactions are validated in a batch. More so, the block generator collects all the transactions and groups them accordingly and then gets them into one block. A validator then has to validate the whole block to verify the transactions.
Here, the leader of the nodes is called a delegate, and it has limited power. If the leader tries to manipulate the network, another delegate will replace that node. More so, other nodes can disagree with the delegate and can change their leader accordingly.
Here, all the general nodes get their own separate blockchain to run. And before any node can request for a transaction, that node needs to be verified and known from the start. Also, here, a node can choose who to trust on the network.
It’s a combination of PoW and PoS. Here, the miners pre-mine a block template rather than a complete one. Later, a validator validates the remaining block. In reality, the more stake a validator has in the network, the more valid his/her validation would be.
Here, the nodes participating in consensus will stake their reputation. Basically, the validating nodes are selected based on their true identities. Additionally, the validators have to invest money and their reputation to earn their place on the platform.
It’s quite similar to Proof of Authority; however, a validator needs to have a good reputation to participate in the consensus. More so, if they try to cheat the network, they would face severe consequences.
Here, the system creates significant events on the network. A node then can validate the transaction based on whether the transaction happened before or after that event.
Here, the blockchain work keeping a score of the importance. The more coins a user has, the higher his/her score will be. Once they are eligible for participating, they can harvest a block. Additionally, if you harvest more, your importance score will increase.
Users would use their available hard drive capacity to select mining rights instead of using computational power. So, the larger your hard drive would be, the more you can validate blocks.
Here, the blockchain works by burning coins to keep the network stable. So, the users would send some of their coins to an eater address and burn them so that they can participate in consensus.
Instead of only relying on how many coins you staked, the system stakes into other factors into account to weigh in. So, even if you have fewer coins, you may still get to participate in consensus.
Blockchain is associated with cryptocurrencies form the very start. That’s why many of you might think that blockchain can’t work without cryptocurrency. But blockchain can work without cryptocurrency.
In fact, there are already many platforms that don’t have any native tokens or coins. A lot of blockchain projects are now moving towards token or crypto less ecosystem. For example, Hyperledger is an enterprise blockchain platform that doesn’t have any native tokens to fuel the network.
The token actually varies significantly based on how blockchain works.
Cryptocurrencies are mostly suited for public platforms as they need some form of an incentive program to keep the users taking part in consensus. However, when it comes to enterprise platforms, they go with mostly permissioned or private ones.
As a result, they don’t need a coin or token to encourage nodes to participate in consensus. More so, cryptocurrencies are actually quite unstable for the economy. In reality, a volatile asset isn’t suited for real-life use cases.
Also, having a token in the system attracts hackers, as well. That’s why experts are predicting that cryptocurrencies will soon fail. So, it’s quite logical to move on to blockchain that can work without cryptocurrency.
Governments or other sectors are interested in taking advantage of the underlying use case of the technology, not a token-based architecture. Maybe cryptocurrencies can emerge in the future when the world is ready for the digital money system.
But at present, it doesn’t seem like a possibility. And so, for your blockchain implementation, you should also focus on a blockchain that can work without cryptocurrency.
However, blockchain is not free from problems. Initially, the blockchain block size was not as big, as only a small number of peers are connected to the network. For example, the bitcoin blockchain size was 614 MB in size in 2012. But now, the bitcoin blockchain size GB has grown tremendously to 250K MB. That’s approximately 250 GB of data that each peer/node carries with them. This leads us to a bitcoin blockchain size problem.
Other blockchain networks also suffer from the same problem. The blockchain size of Ethereum has already crossed 1 TB.
Image source: 101blockchains.com
In the last two years, the bitcoin blockchain ledger size has grown from 150 GB to 250 GB. That’s almost 50 GB per year. By 2030, we can see the blockchain ledger size cross more than 1 TB easily. However, not every node needs to download the whole blockchain to become functional. Some participants take part in the blockchain network to make transactions and not to validate one.
Some nodes are called full nodes. The full nodes are required for those who are willing to participate in the validation of the ongoing transaction. This means that they have to download the whole 250 GB of blockchain data containing the block headers and transactions.
More so, the current bitcoin blockchain size limit is 1 MB. However, some of the space within this limit is not usable. So, you will have to work with the bitcoin blockchain size limit just as it is.
The problem of the blockchain ledger size of Ethereum was more intense than that of bitcoin. Alistair Milne, a bitcoin investor, raised alarms on how the Ethereum ledger size is growing compared to bitcoin. According to the picture posted by him, Ethereum is growing at 3x that of bitcoins.
But, that might not be completely true as Ethereum also offers ways to work with the ledger. It offers a concept called pruning, which allows nodes to work without the need to download whole blockchain data.
Yes, blockchain ledger size matters. Blockchain is relatively a new technology, and it will only grow in the upcoming years. Bitcoin being a first-generation blockchain solution, is not free from problems. It has both scalability and size problems.
With the ever-increasing size of the blockchain, scalability also becomes a problem. It has been one of the significant issues for bitcoin. To temporarily solve the problem, they did a SegWit2x hard fork, which worked towards improving the block size (at the granular level) — improving the scalability and performance issues associated with bitcoin.
The ledger size is going to increase rapidly, with estimates of it each 6.5 TB by Jan 2023. It will bring in the need to buy harder disk space to participate in the network.
However, according to Moore’s law, hard disk storage prices will decrease with time, and you will be able to buy cheaper storage. The main problem arises when the blockchain size growth overcomes the rate at which the storage becomes cheaper.
It will make it hard for the enthusiast to bring in their skills or contributions to the network. Contributors need to spend $1000’s dollars to get their nodes running, which may not be worth it.
We live in a world that thrives on transactions. Every day, there are non-cash payments in billions. The growth of transactions is in a quadratic fashion. However, with cryptocurrencies like bitcoin, Ethereum, NEO, etc., we see a change in how transactions are carried out through non-traditional channels.
Right now, bitcoin doesn’t have to account for a lot of transactions compared to Visa or other forms of transactions. But, if we take a hypothesis where bitcoin is used for every transaction out there, it can take up to 2.4 terabytes for each block.
Also, not to mention, blockchain is capable of generating one block every 10 minutes. In short, every 10 minutes, 2.4 terabytes of data will be added to the blockchain size. In one day, 350 GB is added in one day and 127 TB every year. This also means that there is no ledger limit.
The issue limit brings new problems. These numbers are real concerns. Also, the fact that the block size will increase exponentially, it will take more time for miners to solve a block resulting in slower transactions.
On the contrary, our only hope is cheap hardware in the near future. Terabytes of storage won’t be an issue, and also processing power can grow exponentially, making transaction validation much easier.
So, does the problem impact startups that are building their application on top of Ethereum and bitcoin? Well, it depends on how the two blockchain technologies evolve with time. Right now, startups shouldn’t worry about the size.
Ethereum blockchain already offers pruning, which results in fewer blockchain data than what is needed by a full node. Bitcoin, however, doesn’t support pruning yet. If someone prunes the bitcoin, they will lose the full node status.
Blockchain size is not the top problem that needs to be resolved. In fact, it is the scalability and transaction speed that are the main focus now.
So, what do you think about blockchain ledger size, including bitcoin and Ethereum? Also, there are many more blockchain projects around that focuses on saving space and making it as much as efficient as possible. If you are just a starter and want to more about blockchain technology, we recommend enrolling in our free blockchain course as it focuses on the core concepts of blockchain more thoroughly.

Before working on real-time projects, it is recommended to create a sample hello world project in android studio and get a flavor of project creation as well as execution: Create your first android project
Android Project: A calculator will be an easy application if you have just learned Android and coding for Java. This Application will simply take the input values and the operation to be performed from the users. After taking the input it’ll return the results to them on the screen. This is a really easy application and doesn’t need use of any particular package.
To make a calculator you’d need Android IDE, Kotlin/Java for coding, and for layout of your application, you’d need XML or JSON. For this, coding would be the same as that in any language, but in the form of an application. Not to forget creating a calculator initially will increase your logical thinking.
Once the user installs the calculator, they’re ready to use it even without the internet. They’ll enter the values, and the application will show them the value after performing the given operations on the entered operands.
Source Code: Simple Calculator Project
Android Project: This is a good project for beginners. A Reminder App can help you set reminders for different events that you have throughout the day. It’ll help you stay updated with all your tasks for the day. It can be useful for all those who are not so good at organizing their plans and forget easily. This would be a simple application just whose task would be just to remind you of something at a particular time.
To make a Reminder App you need to code in Kotlin/Java and design the layout using XML or JSON. For the functionality of the app, you’d need to make use of AlarmManager Class and Notifications in Android.
In this, the user would be able to set reminders and time in the application. Users can schedule reminders that would remind them to drink water again and again throughout the day. Or to remind them of their medications.
Android Project: Another beginner’s level project Idea can be a Quiz Application in android. Here you can provide the users with Quiz on various general knowledge topics. These practices will ensure that you’re able to set the layouts properly and slowly increase your pace of learning the Android application development. In this you’ll learn to use various Layout components at the same time understanding them better.
To make a quiz application you’ll need to code in Java and set layouts using xml or java whichever you prefer. You can also use JSON for the layouts whichever preferable.
In the app, questions would be asked and answers would be shown as multiple choices. The user selects the answer and gets shown on the screen if the answers are correct. In the end the final marks would be shown to the users.
Android Project: Tic-Tac-Toe is a nice game, I guess most of you all are well aware of it. This will be a game for two players. In this android game, users would be putting X and O in the given 9 parts of a box one by one. The first player to arrange X or O in an adjacent line of three wins.
To build this game, you’d need Java and XML for Android Studio. And simply apply the logic on that. This game will have a set of three matches. So, it’ll also have a scoreboard. This scoreboard will show the final result at the end of one complete set.
Upon entering the game they’ll enter their names. And that’s when the game begins. They’ll touch one of the empty boxes present there and get their turn one by one. At the end of the game, there would be a winner declared.
Source Code: Tic Tac Toe Game Project
Android Project: A stopwatch is another simple android project idea that will work the same as a normal handheld timepiece that measures the time elapsed between its activation and deactivation. This application will have three buttons that are: start, stop, and hold.
This application would need to use Java and XML. For this application, we need to set the timer properly as it is initially set to milliseconds, and that should be converted to minutes and then hours properly. The users can use this application and all they’d need to do is, start the stopwatch and then stop it when they are done. They can also pause the timer and continue it again when they like.
Android Project: This is another very simple project idea for you as a beginner. This application as the name suggests will be a To-Do list holding app. It’ll store the users schedules and their upcoming meetings or events. In this application, users will be enabled to write their important notes as well. To make it safe, provide a login page before the user can access it.
So, this app will have a login page, sign-up page, logout system, and the area to write their tasks, events, or important notes. You can build it in android studio using Java and XML at ease. Using XML you can build the user interface as user-friendly as you can. And to store the users’ data, you can use SQLite enabling the users to even delete the data permanently.
Now for users, they will sign up and get access to the write section. Here the users can note down the things and store them permanently. Users can also alter the data or delete them. Finally, they can logout and also, login again and again whenever they like.
Android Project: This app is aimed at the conversion of Roman numbers to their significant decimal number. It’ll help to check the meaning of the roman numbers. Moreover, it will be easy to develop and will help you get your hands on coding and Android.
You need to use Android Studio, Java for coding and XML for interface. The application will take input from the users and convert them to decimal. Once it converts the Roman no. into decimal, it will show the results on the screen.
The users are supposed to just enter the Roman Number and they’ll get the decimal values on the screen. This can be a good android project for final year students.
Android Project: Well, coming to this part that is Virtual Dice or a random no. generator. It is another simple but interesting app for computer science students. The only task that it would need to do would be to generate a number randomly. This can help people who’re often confused between two or more things.
Using a simple random number generator you can actually create something as good as this. All you’d need to do is get you hands-on OnClick listeners. And a good layout would be cherry on the cake.
The user’s task would be to set the range of the numbers and then click on the roll button. And the app will show them a randomly generated number. Isn’t it interesting ? Try soon!
Android Project: This application is very important for you as a beginner as it will let you use your logical thinking and improve your programming skills. This is a scientific calculator that will help the users to do various calculations at ease.
To make this application you’d need to use Android Studio. Here you’d need to use arithmetic logics for the calculations. The user would need to give input to the application that will be in terms of numbers. After that, the user will give the operator as an input. Then the Application will calculate and generate the result on the user screen.
Android Project: An SMS app is another easy but effective idea. It will let you send the SMS to various no. just in the same way as you use the default messaging application in your phone. This project will help you with better understanding of SMSManager in Android.
For this application, you would need to implement Java class SMSManager in Android. For the Layout you can use XML or JSON. Implementing SMSManager into the app is an easy task, so you would love this.
The user would be provided with the facility to text to whichever number they wish also, they’d be able to choose the numbers from the contact list. Another thing would be the Textbox, where they’ll enter their message. Once the message is entered they can happily click on the send button.

Developing a mobile application can often be more challenging than it seems at first glance. Whether you’re a developer, UI designer, project lead or CEO of a mobile-based startup, writing good project briefs prior to development is pivotal. According to Tech Jury, 87% of smartphone users spend time exclusively on mobile apps, with 18-24-year-olds spending 66% of total digital time on mobile apps. Of that, 89% of the time is spent on just 18 apps depending on individual users’ preferences, making proper app planning crucial for success.
Today’s audiences know what they want and don’t want in their mobile apps, encouraging teams to carefully write their project plans before they approach development. But how do you properly write a mobile app development brief without sacrificing your vision and staying within the initial budget? Why should you do so in the first place? Let’s discuss that and more in greater detail.
It’s worth discussing the significance of mobile app project briefs before we tackle the writing process itself. In practice, a project brief is used as a reference tool for developers to remain focused on the client’s deliverables. Approaching the development process without written and approved documentation can lead to drastic, last-minute changes, misunderstanding, as well as a loss of resources and brand reputation.
For example, developing a mobile app that filters restaurants based on food type, such as Happy Cow, means that developers should stay focused on it. Knowing that such and such features, UI elements, and API are necessary will help team members collaborate better in order to meet certain expectations. Whether you develop an app under your brand’s banner or outsource coding and design services to would-be clients, briefs can provide you with several benefits:
Depending on how “open” your project is to the public, you will want to write a detailed section about who the developers are. Elements such as company name, address, project lead, project title, as well as contact information, should be included in this introductory segment. Regardless of whether you build an in-house app or outsource developers to a client, this section is used for easy document storage and access.

The blockchain is the decentralized database of the blocks of information, which gets recorded in the chain format and linked in a secured crypto graphical manner. This technology ensures proper safety of the data due to its secure nature, and it totally changes how people carry out transactions. It also brings about a faster and secure process of validating information needed to establish reliability.
Though blockchain technology came into the market to carry out only digital transactions, it is now used in various industries like supply chain, finance, health care, and many more.
The blockchain technology has made its position in mobile app development as well. Blockchain applications are transparent and accountable. From getting easy access to medical records and buying insurance, you can see blockchain applications everywhere.
Here are some of the areas where you can see the use of blockchain applications and how they have changed various industries.
Ripple is useful for increasing banking transactions. The implementation of blockchain technology in the financial sector is much more profound than any other sector. Ripple proves this. It is one of the greatest tools to record and complete financial transactions.
It develops a large network despite strict physical boundaries. As there is no such third-party involvement present, the cost of these transactions is lower than usual. At the same time, the network also remains transparent and quite secured.
It is normally seen that financial transactions that happen globally are
error-prone and take a lot of time. In addition to this, when the transaction
fees and exchange rates get added up, the total cost usually gets high.
However, Ripple offers real-time international transactions without spending too much money. It has the network of about 200+ institutions making the process affordable, secure, and fast for all sorts of international transactions.
This blockchain application helps in automating flight insurance. Insurance is another area where blockchain is gaining popularity. Through this application, insurers can make smart contracts rather than getting involved in the traditional contracts that are usually complex. Etherisc is the blockchain application that helps customers buy flight insurance. If the flight gets canceled or delayed, they do not have to wait for months to get the payment back. This application ensures an on-time payout.
