6 Key Blockchain Features To Know In 2022

Blockchain technology, which began its advent as disruption, has gained the stature of a transformational force considering the multiple utilities it provides and the use cases it can serve across horizontals and verticals, given the key features of blockchain. In this article, we will explore and understand what a blockchain is and, how it works, some of the key features of blockchain that make blockchain what it is today.

What is Blockchain?

Blockchain is a distributed database over a network of computers where data can be safely stored, making it impossible to change or manipulate. In other words, a blockchain is simply a digital record of transactions replicated and spread across the blockchain’s network of nodes or computer systems. Each block on the chain contains several transactions, and whenever a new transaction takes place on the blockchain, a trace of that transaction is added to the ledger of every participant. Distributed Ledger Technology is a decentralized database administered by several individuals (DLT).

The three key technologies that make up the blockchain are a digital ledger, a peer-to-peer network, and cryptographic keys. The two types of cryptographic keys are private keys and public keys. Both of these keys are held by each person or node and are used to generate digital signatures.

The Top 6 Key Features of Blockchain

1. Immutability 

Immutability is the quality of not being able to be altered or modified. It can be considered one of the top key features of blockchain technology. One of the best aspects of the blockchain is that it ensures the technology will continue functioning as a stable, unchangeable network. 

One of the key features of blockchain is the creation of immutable ledgers. Any centrally located database is vulnerable to fraud and hacking since it relies on a third-party intermediary for security.

This Blockchain feature works through the presence of nodes. Blockchain technology works via a network of nodes. A node is one machine that runs the blockchain’s software to verify and preserve the whole record of whatever transactions occur on the network.

A copy of the digital ledger is stored on each network node. Each node evaluates a transaction before adding it to the network, and if the majority of the nodes agree that it is valid, the transaction is added. This indicates that no transaction blocks (group of transactions) can be added to the ledger without receiving the consent of the majority of nodes. Any records that have been validated are final and cannot be altered. This implies that it won’t be editable, modifiable, or deletable by any network user. 

It is reasonable to anticipate that this key feature of blockchain technology can significantly alter many situations where there is a need to eliminate corruption or manipulation. Therefore, nobody would be able to hack into it, change it, or even steal information if businesses started using blockchain to operate their internal networking system. Immutability as one of the blockchain features also helps in granting traceability of transactions. 

2. Decentralized

In a blockchain, there isn’t a single individual or organization overseeing the framework. The network is decentralized since a collection of nodes maintains it. One of the most important features of blockchain technology that grant it the status of disruption is this, given how it proves a great alternative to centralized systems. Users are put in a clear position of authority by the blockchain. This key feature of the blockchain benefits us so that we can immediately access the system via the web and put our assets there because it doesn’t need any regulating body or third party.

A decentralized network like blockchain has many benefits, such as a much lower chance of failure and greater security as blockchain operations are automated and do not require much human control, resulting in a lower chance of failures or errors.

Another major benefit of this key feature of blockchain is that there is no single point of failure because the decentralized system distributes each database among numerous nodes worldwide. As a result, the blockchain will remain secure even if any computer is compromised. This key feature of blockchain also provides complete transparency to the users. 

Blockchain’s decentralized nature allows users to manage their assets and data independently. They are not dependent on a third party to care for their assets. They may all complete it concurrently on their own.

3. Enhanced Security

No single node can alter any blockchain properties or records for their benefit since there is no longer a requirement for a central authority or intermediaries to facilitate transactions. An additional layer of protection is provided for the system using encryption via hashing and cryptography. 

The blockchain’s records are all individually encrypted. The blockchain network’s entire process is made more secure by using encryption. This is one of the key features of blockchain technology as we know it, as it provides a safer space for users compared to the current form of the internet (Web 2.0).

Another key benefit of blockchain technology’s safe environment is that every few minutes, the blockchain network automatically verifies and updates itself; this aids in the creation of a self-reviewing system. It aids in offering a very stable system. All data is public because it is incorporated inside the network. As a result, it contributes to transparency.

Anyone attempting to change the block data on the blockchain would require a significant amount of computer power before the rest of the network could react. This shows that it is extremely hard for hackers to penetrate and compromise the network. 

The consensus mechanism via which a blockchain validates transactions allows an additional layer of security. The combination of hashing algorithms, public-private keys, and consensus mechanisms helps to make security one of the key features of blockchain. 

4. Distributed Ledgers

A distributed ledger like blockchain will typically give you all the details about a transaction and the parties involved. There is nowhere to hide because everything is visible. However, the justification for a private or federated blockchain is rather different. A blockchain’s database is stored on every node on its network and is immutable, open-source, and transparent. 

Public ledgers make details of transactions and participants available to the general public. Unlike private or federated ledgers, which can also be linked to a blockchain system, these ledgers lack security or authority. This is so that all other system users can maintain the network’s ledger. Anyone with the necessary access can view the distributed ledger, which increases the process’s transparency and dependability.

This key feature of blockchain also has many benefits, such as the fact blockchain ledgers are tamper-Free. Ledgers are created in a way that makes it impossible for anyone to alter the ledger, and updates occur practically instantly. There is also no kind of bias with distributed ledgers. This is one of the key features and benefits of blockchain technology. Nobody using the network can receive special favors or encounter any form of bias from the network nodes. The process for adding blocks is the same for everyone.

5. Consensus Algorithms 

The decentralized in a blockchain happens successfully due to its consensus algorithm. It is a distinctive trait and an essential component of any blockchain. Consensus involves a validation process within the group of active nodes involved in the network’s decision-making process. The nodes can reach an agreement in this situation pretty rapidly.

The consensus assists the network in reaching choices quickly and impartially. The consensus mechanism helps make the decision-making process swift, prompt and efficient. The algorithms that run at its heart can be trusted even if the nodes do not trust one another. Because of this, every action taken on the network favors the blockchain. There are numerous available consensus algorithms, like Proof-of-Work, which the Bitcoin and Ethereum networks use, Proof-of-Stake, Proof-of-Authority, etc., each having advantages and disadvantages. A consensus method is necessary for any blockchain, or else it will start to lose the key blockchain features for which it is valued.

Miners or network validators validate transactions using the consensus mechanism. For instance, in the Proof-of-Work consensus, miners compete to solve complex computational problems to find the unique hash that will represent the transaction block on the blockchain. The miners put in resources and computational power as ‘proof’ of their contribution to the network, eliminating the bad actors. The transactions are validated when the nodes check the database to test whether the transactions can be approved. 

If any hackers dare to try their hand at corrupting the network in any way, they would have to have control over approximately 51% of the network nodes to be able to change them and be remotely successful. The whole process of hacking and trying to gain control of millions of computers to change up the millions of copies that millions of people across the globe have access to is an almost impossible feat.

6. Faster Settlement

Blockchain offers faster settlements compared to traditional banking systems. This key feature of blockchain technology has a lot of benefits and is one of the many unique features that sets blockchain apart.

Because they typically take days to complete and take an awful lot of settlement time, conventional banking systems are incredibly slow. One of the key causes for these banking institutions’ need to modernize their banking systems is this. Blockchain can help us overcome this issue by quickly resolving money transfers. In the end, this saves these institutions a tonne of time and money and offers ease to the customer.

Banking makes great use of blockchain. Currently, a user repeatedly verifies his identification with each bank he visits. The use of blockchain can make the overall procedure much faster and easier for users around the globe. For instance, Ripple assists hundreds of banks around the world in real-time settlements. 

Faster settlements are one of the main features of blockchain. To put it another way, it eliminates the middleman to increase transactional effectiveness and speed. This key feature of blockchain benefits its users in such a way that it helps businesses keep track of data and transactions. The scope expands with transaction speed.

Conclusion

For quite some time now, it has definitely made its mark across various existing and prominently established industries and has managed to become a mainstream phenomenon that is gaining more traction day by day. Blockchain is at the heart of the development of popular concepts such as the metaverse and web3 due to its key features and all the benefits they provide, such as transparency, trustworthiness, and tamper-proof qualities. It is crucial to improving commercial and governmental processes’ safety, effectiveness, and efficiency.

The concept of blockchain is still being built upon and modified every day, with new and unique features constantly introduced to provide users around the globe with better technology, so you should keep yourself updated about any new changes of such nature!
