Simple blockchain projects

Blockchain technology is generating a lot of interest nowadays, but technologies by themselves do not generate revenues , there must be business and projects to implement them and here we go: the top mistakes to avoid in Blockchain projects! This is the typical feeling when a new technology arises and people have not a clear idea of its benefits. Everyone thinks that they are missing the next big thing, they believe that their business are in risk and will be superseded by newcomers. To be fair it is difficult to say if starting a project due to FOMO is an error or not. And obviously it is applicable not only to Blockchain but to all the new and potentially disturbing technologies. But do not jump into the abyss and start a dozen of new projects, because it will be difficult to focus and find out the real benefits.

How Blockchain Could Solve the Problem of Digital Identity

They try to implement it in whatever sphere comes to mind, whether it is fashion, education or healthcare. I would say it is okay — too little time has passed to determine which area of human activity can benefit the most from applying this technology.

To understand the practical application of blockchain, we must first define why it appeared, and then study cases when blockchain can make a significant difference. Note: This article does not explain the blockchain concepts; instead, it focuses on developing a fintech application using this technology. I will explain why fintech can already adopt the blockchain, and most importantly, focus on developing a decentralized application using this technology.

Don Norman once wrote that many products failed because they were released at the wrong time. I can remake this statement and say: Many technologies fail to find practical applications.

It was a catastrophe, and its consequences are still visible by thousands of never-visited websites with horrible interfaces, clumsily created by anyone who had a computer.

We are currently witnessing virtually the same situation—the most potential technology of the decade is associated with speculations on crypto-exchanges.

It is widely used for financial scams, although it was initially created for the contrary. Source: Microsoft Azure An attempt to exclude the human factor from the business was one reason why blockchain appeared. That is why the industries that may have blockchain successfully implemented are those that 1 heavily depend on human activity, and 2 suffer most from human errors, like finance.

Important: Blockchain is being applied to various products from different industries; we just need more daring entrepreneurs who are willing to put a lot at stake. Fintech deals with a very thorny matter — money. It is exactly where most fraud takes place. The desire to become richer is one fundamental mechanism that pushes people to do things, often bad things. Fintech startups aim to improve the traditional financial institutions, for example, excluding the human factor from the financial activities.

Utilizing blockchain excludes third parties from the financial transactions, like a bank that verifies the person between which the transaction is made. It can be used for managing the inventory and logistics, trading goods, optimizing the person identification, tracking transactions and more.

Here are some cases when you might want to use blockchain:. What you can do tomorrow, and even while reading this article, is to build a simple blockchain. It is the focus of part 2. I will tell you about the main components that are required to build a blockchain for fintech products, propose some tools, and show real pieces of code with explanations. CryptoNote is an open-source project that allows you to create crypto coins. They have a simple, step-by-step guide to creating a cryptocurrency.

To launch it, you will need to have two nodes which will be used to run the Monero server. Useful links: How to create a coin How to create a wallet. A popular open software platform for building decentralized applications. Its focus is running the programming code of your blockchain-based app. ZeroNet is used for creating decentralized websites. It uses the Bitcoin addressing and verification mechanisms, and the BitTorrent distributed content delivery network to create sites that cannot be censored, forged or blocked.

Now that you know the tools — Cryptonote, Ethereum and ZeroNet — we are moving to building a basic blockchain of our own. I will be using Python in this example, but if it is not your primary coding language, you will still understand the logic and be able to write it in another language. First, I will explain the fundamental elements required to build a block.

I will start with date of creation, nonce, checksum and transaction data. Transaction data in our case could be just a string to simplify the code. It is the current and time in unix format. It is required for the future development of your blockchain; when there are many running nodes and you add a new block to your branch, the node will decide which block to use based on Date of Creation. For example, if the nonce value is 5, then we have to add 5 zeros to the data block to calculate the right checksum.

Also sometimes referred to as hash value, hash code, or simply a hash. It is block data with nonce plus checksum of previous block. SHA protects the ledger chain from being rewritten. How it works: Node calculates the checksum and compares to the one of the new block; if they match, the block is added to the blockchain.

It can contain any sort of data: e. Proof of work PoW is a unique consensus algorithm in a blockchain network. It is used to validate the operations and the creation of new chains in the blockchain network. The main idea of PoW is to add complexity to building a block on the client side and reduce the load on the server side.

For example, I say checksum has to have 5 lead zeros; it means that we will increase nonce until checksum will not have 5 lead zeros. First of all, I will create a class for a block. It will be a very simple class with a constructor, a method for calculating the checksum and property to check that block is valid.

We will have two constants, one for number of lead zeros in checksum and a second to identify which symbol we will use with the nonce. Constructor accepts only two parameters; the first is a previous block, and the second is the current block data. Also, constructor creates the time mark and sets nonce to zero as its initial value. A property that calculates checksum and compares if the current one is equal to the calculated and has the right number of zeros.

The most complicated method in our code. This method packs the time mark, data, and checksum of the previous block to one string. Then it calculates the checksum of result string. Now we have a simple yet fully functional block. I will move on to creating a chain of blocks. For now, it will be a simple chain without the ability to store and load data, but it will convey the main idea.

I just created a chain with only one block — a genesis block. Genesis block is a first block of the chain and has only a checksum. This block is required for adding the first real block to the chain because the real block requires a checksum of the last block in the chain. It has only one parameter — data for a new block. This method creates a new block with the given data and run method to find a correct nonce value.

Only then, it will append a new block to the chain. This method aims to find the right nonce for a block. It has an infinite loop where I increase the nonce and calculate a new checksum. Then it compares the checksum with the rules — for now, it is only the number of zeros. This method tells us if the chain is valid. It goes through all blocks in the chain and checks if each block is valid. In this article, I attempted to prove that building a simple yet working blockchain is not as difficult as it may seem.

My general advice is to take the lesson you learned here and start playing with blockchain by experimenting with blocks and data. All great products, including blockchain, were experiments once. If you are from the fintech industry, I suggest you study more about the products that are using blockchain. Some things about them are certain; they are more secure, more attractive for investments, and, if they succeed in the global market, will be called game changers.

The first step of adapting the new technology has been taken. The next step is to spread the knowledge and educate people about the features of blockchain. Stay tuned for the next part about blockchain and fintech, most likely with more complex pieces of code and suggestions on its practical application in fintech from our Python development company.

Vadym Zakovinko. Technologies are changing fast; people are not. Here are some cases when you might want to use blockchain: You want to attract investments. Like it or not, blockchain is still a buzzword. It attracts more investments than common working products. Though, to get those funds you should prepare a convincing investment proposal , but blockchain solution may become a game changer for yor product.

You want to increase your competitiveness in the market. If you manage to build a product on blockchain successfully, you will instantly show your professionalism, thus becoming more attractive to investors and customers. You are ready to experiment. Yes, any blockchain-based product is an experiment because few know what this technology is capable of. If you are ready to make a breakthrough in your industry, blockchain could be a right choice.

I do not suggest implementing blockchain in the following cases: You are limited in resources. It is a high-risk way to creating a product because 1 there are few blockchain engineers, and 2 it is expensive to have them in the team. You are not ready for significant changes. The changes include operational management and human resources. If you are a bank that has implemented blockchain, you will most likely need to let many employees go since there will be less work for people.

You have short-term vision. Blockchain is about long-term perspective.

Facebook's parent and its partners are looking to get out of the troubled cryptocurrency project, according to a report. It may be the end of the day for Diem, Meta's troubled cryptocurrency. Facebook parent Meta and its partners in the Diem Association are reportedly pulling the plug on the yet-to-launch cryptocurrency project amid growing resistance from regulators. Earlier this week, Bloomberg reported that the association, which oversees the digital currency, is considering a sale of its assets in order to return capital to its members. Discussions are still early , the news service reported, and are focused on how a sale of its intellectual property might work and where the engineers who developed Diem might find jobs.
