Let me start by commending the Admin and Moderators of the Steemit Crypto Academy community for completing season 7, and entering season 8 of the engagement challenge. Your efforts and hard work are greatly observed and appreciated bosses.
For the first week, you presented an interesting topic titled The Importance Of Blockchain Technology by @crypto-academy.
The advancement of blockchain technology has revolutionized the way we think of data storage and security. It is a powerful tool that can revolutionize the way we conduct business, store and manage data, and even facilitate new forms of currency.
The Principal Problems Arising In The Existing System Of Blockchain Technology |
|---|
You would agree with me that blockchain technology has become increasingly popular as a method of securing digital transactions. However, as with any technology, certain issues have risen from its use.
Here are some of the main issues detected to have risen from the existing system of blockchain technology;
When it comes to blockchain technology, security is a major concern, because it is built upon distributed ledgers, which create an immutable record of transactions and data, making it more secure than traditional databases.
However, due to the decentralized nature of blockchains, they are vulnerable to malicious attacks. Hackers can use various methods to compromise the system, such as the 51% attacks, double-spend attacks, and front-running.
That's why we see various cases of companies trying to mitigate these security risks, as many organizations are now using advanced technologies such as cryptography, consensus algorithms, and digital signatures.
Cryptography is used to secure data and encrypt communications, while consensus algorithms ensure that all participants in the network agree on the same data. Digital signatures are also used to verify user identity and authorize transactions.
The distributed ledger technology of blockchain provides unparalleled transparency, making it a preferred choice for applications requiring secure and traceable transactions. However, this increased visibility also presents some privacy concerns.
As the data stored on a blockchain is publicly accessible, users may be reluctant to put sensitive personal information in the ledger, such as their identity or financial transactions.

That's why some developers have come up with the idea of maintaining user's anonymity, by introducing the use of zero-knowledge proofs to verify a user’s identity without revealing their personal details.
And we could equally see many projects actively working on privacy-focused cryptocurrencies, such as Monero, Zcash, and Dash. These digital currencies are designed to protect the identity of their users, allowing them to make transactions with complete anonymity.
One of the major issues with blockchain technology is its energy consumption, because the consensus mechanisms underlying many blockchain networks, such as proof-of-work (PoW), are extremely energy intensive.
Bitcoin, for example, requires an estimated annual electricity consumption equivalent to that of the entire country of Switzerland. You would agree with me that this is not only unsustainable but also potentially damaging to the environment.
Fortunately, there have been potential ways to reduce the energy requirements of blockchain networks such as the implementation of the proof-of-stake (PoS) mechanism which does not require expensive mining operations and therefore reduces energy consumption.
Scalability has been observed to be one of the major and most popular issues with blockchain technology, given the fact that many blockchain networks are still relatively slow and aren't able to solve lots of task at the same time.
This means that if a particular network becomes popular, it can quickly become congested and transactions take longer to process.
Furthermore, the transaction fees associated with certain networks tend to increase exponentially as the number of users grows. This makes it difficult for these networks to be used in everyday transactions, as fees can get quite expensive for users.
Although many speculate that this challenge can't be completely solved, there have been proposals for various potential solutions to this issue such as sharding, off-chain solutions, and sidechains.
Interoperability is another challenging issue facing blockchain technology, and this means that different blockchains and their applications should be able to interact and exchange information without any hindrance.
In the current system, different blockchain networks are not able to communicate with each other, leading to increased cost, time, and effort when exchanging data between them.
The most common approach observed to solving the interoperability problem is through bridging networks or cross-chain protocols. These protocols allow users to securely send tokens from one network to another.
For example, a user can send Ethereum tokens on the Ethereum network and receive Bitcoin tokens on the Bitcoin network. This is made possible by the use of interoperable bridges that act as intermediaries between the two networks.
Some Main Features With Blockchain Technology |
|---|
Many newbies might be wondering what exactly are the features of blockchain technology and what makes it so special.
There are many interesting features of blockchain, ranging from its ability to increase trust and transparency in transactions to the potential for smart contracts, blockchain technology is far more than just a buzzword.
Some of its key features include:
As you might have rightly guessed dear steemians, this is by far one of the most special and key features of blockchain technology. It is an important concept because it eliminates the need for a central authority or intermediary, such as a bank or government, to manage transactions.
Instead, blockchain technology relies on a distributed network of computers that maintain and validate the ledger.
The decentralized nature of blockchain technology makes it resistant to manipulation and tampering, given the fact that each block contains a cryptographic hash of the previous block, as well as its data.
Thus, if someone were to try to change any information in a single block, they would have to also change every other block after it. This makes it nearly impossible to manipulate the blockchain.
This is another key feature of this technology, where transactions made on the blockchain are recorded and stored in a public ledger, making them easily accessible to anyone with an internet connection.

Every transaction is visible to everyone, meaning that all participants can see the same information at the same time. This level of transparency allows users to verify the authenticity of a transaction and also helps to maintain trust within the network.
It also helps to reduce potential instances of fraud as all transactions can be seen and tracked by anyone.
You would agree with me that immutability is one of the most important features of blockchain technology and it refers to the impossibility of changing or reversing any action or transaction that has already been executed.
This means that once a block has been added to the blockchain, it cannot be altered in any way, and this is what makes the blockchain so secure, as it prevents any malicious actors from manipulating the data stored within the network.
The immutability of the blockchain is achieved through the use of cryptography and digital signatures, which are two methods for verifying the integrity of the data stored on the blockchain.
Cryptography ensures that no one can manipulate or modify data without first obtaining the required authorization from the system. Digital signatures, on the other hand, allow users to verify their transactions without having to trust any third parties.
Security is another important feature of blockchain technology and is essential for maintaining trust between users.
In a blockchain system, each transaction is digitally signed using cryptographic techniques to ensure that it is only the sender who can authorize it. This means that no third party can tamper with the data stored on the blockchain, making it more secure than traditional banking systems.
Additionally, the use of cryptographic keys to authorize and authenticate transactions also helps to ensure that the data remains safe from malicious actors.
It's equally important to note that smart contracts, which are digital agreements coded into a blockchain, help to further enhance security since they can be used to automatically execute certain actions when certain conditions are met.
Another key feature of blockchain to point out here is the improved efficiency it offers. Since Blockchain technology is decentralized, it eliminates the need for third-party intermediaries which can slow down and increase the cost of transactions.

This reduces transaction times and costs, making it an attractive solution for many businesses. All of these features combine to make Blockchain technology a powerful tool that can significantly improve efficiency in all industries.
A Basic And Simple Understanding About The Workings Of Blockchain Technology |
|---|
Blockchain technology has indeed become a major topic of discussion in the tech and business world. However, to many individuals, the concept of blockchain can be confusing.
Follow as I would be sharing some basic and simple explanations of how blockchain technology works, so you can get a better understanding of its inner workings.
Distributed ledgers are the basis of blockchain technology, as they are a form of database that is spread across multiple sites, regions, or participants.
Unlike a traditional ledger, which is centralized and managed by one party, distributed ledgers are managed by multiple parties who come to a consensus on its contents.
In a distributed ledger, all participants have access to the same data set and all changes are securely recorded with cryptographic keys.
Every transaction is written onto a new “block”, which is linked to the previous block via cryptography, and this creates an immutable chain of records that cannot be altered retroactively without changing all subsequent blocks.
By ensuring every node in the network has the same data set, distributed ledgers ensure consensus among participants and reduce the risk of fraud or double-spending.
Distributed ledgers also provide greater transparency and security than traditional ledgers, as all changes are recorded in real-time, so participants can view any transaction as soon as it happens.
Smart contracts are self-executing programs that are stored on a blockchain and executed automatically when predetermined conditions are met. They are designed to be used for transactions, agreements, and other important functions.
Smart contracts are written in computer code, which is then compiled and deployed on the blockchain, and this code is immutable, meaning it cannot be changed or reversed once it has been uploaded.
Every time a smart contract is used, a permanent record is stored on the blockchain which shows all the steps taken to reach the desired outcome.

By removing the need for manual intervention and paperwork, smart contracts can significantly reduce costs and improve efficiency, as they can automate processes such as payments, supply chain management, and other business operations.
Smart contracts can help ensure that parties adhere to the terms of a contract, and If the conditions are not met, the contract can be automatically rejected and no funds will be exchanged.
Decentralized networks are at the core of blockchain technology, as these networks consist of several computers, or nodes, that are connected over the internet.
Each node runs a copy of the same software and stores a copy of the blockchain, and the network is distributed across many different computers, so no single entity has control over it.
This type of system is secure because if one computer fails or is compromised, the others can still function normally.
Decentralized networks provide several benefits, which include security, since the data stored on them cannot be modified without the agreement of all nodes in the network.
They are also transparent, since all transactions can be seen by anyone who has access to the network, and they are equally resistant to censorship since no single entity can block or delete data stored on the network.
Cryptography is an essential part of blockchain technology, given the fact it ensures that data on the blockchain remains secure.
Cryptography refers to the process of encoding information in a way that only those with the right key can access it.
In the context of blockchain, this means that data and transactions stored on the network are encrypted, meaning they cannot be tampered with or altered.
This ensures the security and privacy of the data, as only those with the right key can access and decode the information.
Cryptography also plays a role in preventing double spending, as each transaction on the blockchain must be validated through cryptography.
With the use of cryptography, all nodes on the network can validate each transaction, preventing double-spending.
My Understanding Of How We Could Use "Zero Knowledge Proof Of Authentication |
|---|
Zero Knowledge Proof (ZKP) is a cryptographic protocol that allows one party (the prover) to prove to another party (the verifier) that they know a certain value without revealing the actual value.
In this type of proof, the verifier must be completely convinced that the prover knows the secret, while the prover must not reveal any information about the secret to the verifier.
ZKPs are built on mathematical proofs and are used in various areas of security, including authentication and access control.
This can be done by providing the second party with an encrypted version of the data that can only be decrypted with the original data. The second party will then verify that the data is correct without being able to access the content of it.
The process begins with a verifier and a prover, where the verifier has an algorithm and a set of questions that must be answered for the verifier to be able to confirm that the prover knows the information. The prover has the answer to these questions but does not want to reveal them.

The two parties then go through a series of interactive steps called the ‘challenge-response’ protocol. In this protocol, the verifier sends a challenge to the prover, which is essentially a request for an answer to the verifier's questions.
The prover responds to this challenge by sending back an encrypted version of the answer, while the verifier then checks the answer against its own data to ensure that the answer matches.
If the answers match, then the verifier can confirm that the prover knows the information without being able to access it directly.
This technology can be applied to a variety of use cases, such as cryptocurrency payments, identity verification, medical records access control, data privacy, and more.
The Advantages And Disadvantages Associated With Blockchain Technology |
|---|
As we have learned thus far, blockchain technology has the potential to improve how data is stored and transferred, with countless applications in the world of finance, healthcare, and even politics.
it’s important to understand both the advantages and disadvantages that come along with the use of blockchain technology. So follow as I would be highlighting the pros and cons of blockchain.
Blockchain technology allows users to be in control of their own data and keeps it out of the hands of third parties.
It equally provides transparency, as all transaction data is available on the distributed ledger and can be viewed by anyone with access. This means that users can track their transactions and ensure that their information is being handled correctly.
Users can verify the legitimacy of other users on the platform, helping to create trust and reduce the risk of fraud or scams.
Blockchain technology also offers increased efficiency, by eliminating the need for third parties and reducing paperwork, where users can enjoy faster transactions and decreased costs.
Blockchain technology can help reduce human error, by automating certain tasks, whereby mistakes are less likely to occur, and transactions are faster and more accurate.
Blockchain can be slow and expensive when it comes to processing transactions, as it’s estimated that the Bitcoin network can only process a maximum of seven transactions per second, whereas traditional payment networks like Visa can process up to 24,000, making it difficult to scale in certain cases.
The cost of using blockchain can be prohibitively expensive, particularly if users want to record large amounts of data on the chain.
The amount of energy required to mine Bitcoin has also been a major issue, as it’s estimated that it uses more energy than entire countries.
Security is another factor to consider, although blockchain is theoretically secure, there have been cases of hacks and fraud. For instance, there have been numerous reports of people having their cryptocurrencies stolen from wallets and exchanges due to poor security practices.
Regulations around blockchain technology are still in flux, as it's still relatively new and untested in many areas.
Conclusion |
