Things to know when Building Blockchain

The ideas around blockchain are significant because they’re the engine that enables cryptocurrency to be so secure and cohesive. It’s crucial for us to differentiate their value from the actual data they usually contain, like Bitcoin transactions. Blockchain technology isn’t only for cryptocurrency; cryptocurrency is just what helped it break into the mainstream.

With all of this said, how do we sort through all of the buzz? I believe that by asking three questions, we’ll be able to understand the value of blockchains much more clearly:

  1. What exactly makes up a blockchain?
  2. How would we implement our own version of blockchain?
  3. Is using blockchain right for my company?

Dissecting a Blockchain

At a high level, a blockchain is a series of decentralized databases that are connected to a large, distributed network. Each database contains and generates records known as blocks. These blocks can contain literally anything, but they do have a few constant attributes:

  • An encrypted hash of the previous block
  • A timestamp
  • Payload data, eg, transaction data

Each of these pieces plays a crucial part in making the blockchain unique and secure. Most implementations use the encrypted hash of the previous block and timestamps to check the validity of a new block. No previous block can be modified without the complete change of every other block in the chain.

In other words, every block must be in chronological order and have the previous block referenced to it. Any modification of blocks outside of this wouldn’t be accepted by the blockchain at large.

Another thing that makes this architecture unique is its emphasis on decentralization. This means that an entire blockchain isn’t located on just one main machine or database. Individual blocks are distributed in numerous computers around the world.

In order for someone to maliciously control and alter a blockchain, they would have to control all blocks across all of its networked computers!

While this is certainly possible on smaller blockchains, the probability of achieving total ownership of a blockchain diminishes with each new computer added to the chain.

Reading about all of these higher-level ideas might seem like a satisfactory business pitch, but how would you actually build one from a technical perspective?

Creating a Blockchain

Bitcoin is actually a wonderful place to start on this subject. The entire framework of the cryptocurrency is open source and available online. Looking at Bitcoin’s implementation, we can see a few common themes:

  • We need something to store.
  • We need a distributed network of computers to power the transfer, creation, and verification of blocks.
  • We need a means of incentivizing other computers to join our blockchain.

Stored records

As I mentioned earlier, there’s a difference between a blockchain and the valuable things it stores. There is technical importance around what exactly is stored in each block. Historically, blocks have stored information that has a record-like format. For example, Bitcoin transactions are what Bitcoin’s blockchain stores.

However, one could argue that, due to the open-source nature of blockchain’s design, it could be extended and modified to store anything. We just need to make sure that whatever is being stored within a block can interact with previous copies or iterations of itself. This is why records tend to be the natural choice for storage on a blockchain. They’re unaffected by whatever comes before or after them; they’re simply a recording of something that occurred at a specific time.

Chained computers

Another thing we’ll need is a series of computers to power the entire chain. These computers will need to be constantly connected to each other and actively contributing computing power to the chain.

Many implementations encourage computers to help “mine” or create and verify new blocks as well as store existing ones. However, incentivizing other computers to invest all of this computing power can be tricky.

Participation incentives

This is where mining incentives come in. We need a means for our computing power to not only participate once, but also continue to participate in our blockchain.

The reason that cryptocurrency has been so popular in the past is because they’ve rewarded users with Bitcoin and the like in exchange for helping power various blockchains.

Now that we’ve explored what makes up a blockchain, why would we actually want to build one for ourselves or others? Furthermore, why would we choose this implementation over other solution architectures?


Understanding When to Utilize Blockchain

Blockchains are complex and expensive pieces of technology to build and maintain. They require a lot of computing power and the willing participation of networked computers. So, it’s safe to assume that they aren’t a solution for every problem we may have.

Public record

Furthermore, companies must ask themselves whether they want the information stored in the blockchain to be of public record or of private record. Depending on the answer, you would either have a public or private blockchain.

Both have their pros and cons, though it’s worth noting that the blockchain was designed from the public point of view, so private ones are somewhat new.

Public blockchains are chains that have a focus on incentivizing and enlisting the general public into joining their mining pools. They must not only have something valuable to the public at large, but also a valuable means to incentivize folks to help power it (again, why cryptocurrencies are so popular).

Private record

On the other hand, private blockchains are private networks that power decentralized databases. These chains are able to store information in a private and somewhat secure matter (since not everyone can join), but they increase the effort it takes to compromise a data set by quite a bit. It might be useful to store confidential transaction data, secure plans, or even simple assets like movies on these chains. These private blockchains might be able to prevent things like massive hacks of major companies in the future.

Both of these approaches come at different costs. You’ll be spending extra computing power and storage to simply verify and create the means for storing this information. Sure, technologies and methodologies for each of these aspects are getting better constantly, but whenever you jump into developing a blockchain, you’ll be committing to the current specs of the technology you’re using.

Its really important to ensure that the information you’re storing is valuable and worth putting all this effort into scattering and securing. Financial data makes a lot of sense — like many things we exchange, it has a value, and we often accumulate it privately. Yet, it would be quite costly if I just stored something like random cooking notes on a blockchain.

The computing costs are pretty high to secure pieces of information that aren’t really the valuable.

Wrapping Up

At the end of the day, the ideas behind cryptocurrency and the blockchain are very interesting. It’s just really difficult to see them at the moment because of the massive amount of attention around the value of cryptocurrency right now. If we can see through the hype and find the right use case, implementing a blockchain may very well change how many core technologies are structured and created.

5 Blockchain Applications That Have Transformed the World of Technology

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.

1. Ripple

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.

2. Etherisc

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.

A multitude of use cases around the numerous industrial segments are now contained in the blockchain technology that once began as the underlying system for Bitcoin trading. One of the main impacts on the financial sector has been felt. Blockchain technology has been publicly adopted by businesses like JP Morgan. The financial sector is suffering from data protection problems, faster transactions, transparency and other bottlenecks that hamper the growth of businesses that rely on monetary transactions from banks and NBFCs. Blockchain could therefore be a possible solution here. Banks and financial sectors can easily solve the disadvantages that hold back the banks’ smooth functioning with Blockchain’s involvement.

Some of the biggest developments we have seen in the Blockchain sector are the development of Blockchain platforms such as Hyperledger Sawtooth, Hyperledger Fabric, Corda, etc This approved Blockchain not only ensures that the system operates efficiently, but also ensures that transactions take place at a faster rate. It actually helps the banking system work much better and in a more effective way.

How the financial sector is impacted by Blockchain:

1. Providing a safe platform-
The need for a secured platform is one of the greatest challenges facing most banking and financial institutions. As most of the transactions and other work have now been digitised, most banks and other allied companies are looking for a stable platform that is free of any mistakes or defects. In addition, there is also a high rise in the need for a network that can efficiently combat data breach problems, and so we have Blockchain. By time-stamping all information or data on it this DLT platform works. This guarantees full security. And with the introduction of approved Blockchain networks, the security feature is even more assured.

2. No third party- Time lag and paperwork are two weaknesses of the financial sector that appear to hold up the processes and ultimately influence the company’s efficiency as well. We can solve these problems with the assistance of Blockchain technology and thus ensure quicker transactions. Blockchain technology operates on peer-to-peer transactions, ensuring that for authentication and approval, there is no need to rely on a third party, which speeds up the transaction process.

3. Tracking and tracing- For banking firms, these features can be highly beneficial. Banks invest a large amount of money on authentication and verification, amid all the efforts of false identity cases, and fraud reports are growing, we can easily put an end to it with Blockchain. As data tracking and tracing becomes simpler and history can be easily traced back, compared to the traditional technologies that banks use, it becomes easier to rely on this platform.

These are the three big benefits that Blockchain can reap from the banking and financial field. Blockchain developers and Blockchain experts are in high demand because of this, and we will see an increase in this number in the times to come.

All You Need To Know About Transactions In Blockchain

The technology of record-keeping behind Bitcoin has now emerged as a popular technology that, through the numerous industrial segments, finds many applications. Cryptocurrency exchanges or transactions, however, were the main explanation for Blockchain’s success. Blockchain and Bitcoin ultimately paved the way for the financial digital revolution.

Unlike the traditional database, all the data or transactions are chained by Blockchain. This implies that any data entering the DLT as the block is connected to another block, any interference in any of these will affect the other, reflecting in the ledger. What contributes to Blockchain’s security aspect. This Blockchain feature makes it ideal for cross-border transactions with improved protection, safety, and speed.

Blockchain transactions:
Let’s explain how the blockchain operates and how the transactions are secured.

Peer-to-peer interaction: Well, peer-to-peer interaction facilitates the operation of the Blockchain in plain terms. This implies that the two parties concerned communicate directly without relying on a third-party for approval and confirmation. Therefore, a lot of costs are saved in the form of processing fees, transaction fees, platform fees, etc.

Safe transaction: The safety and security features are next. Developers of Blockchain work to build a safe and secure Blockchain platform. All the transactions or data exchanged through the Blockchain platform is also cryptographically encrypted. It guarantees that all transactions are secure and secured. You don’t need to worry about data breaches and risks. This encryption of data guarantees that all data is protected and free from hacker attacks.

Faster processing: Blockchain helps P-2-P transactions where one does not have to wait for approval and confirmation by third parties, as discussed above. This guarantees that transactions are carried out at a quicker pace. In general, it can often take longer hours for a cross-border transaction, but this time is reduced with Blockchain. There is less time loss since all the interacting groups are directly in contact with each other.

Smart contracts: Smart contracts have become one of Blockchain’s main applications. These digitised contracts have predetermined conditions agreed by all the interacting parties, and the contract is executed and the payment is issued when these conditions are met. In real estate and financial transactions, smart contracts are currently being used.

These are some of the Blockchain transaction’s key features. Scalability remains, however, a matter of concern. Blockchain Developers are working to build a fast and scalable network so that it can present itself as an infallible monetary exchange mechanism.

And what is next?

The increasing use cases of Blockchain technology and its implementations indicate that we will see some huge advancement in the field of technology, and there will be an increasing appetite for experts from Blockchain and developers from Blockchain who can exploit this technology. This is the time to register for the Blockchain certification programmes provided by the Blockchain Council, if you are also eager to join the best Blockchain developers’ league.
