Cryptocurrency and blockchain solutions are making waves across various industries today. Originally designed for financial record-keeping, blockchain has expanded its reach.
Ever wondered what makes blockchain stand out in the world of data management?
Blockchain, born in 1991, serves as a secure digital data storage system. It functions on a distributed ledger, tracking changes to assets within the chain.
According to Statista, worldwide investment in blockchain solutions will soar from $3.7 billion in 2020 to $15.85 billion in 2024.
Blockchain technology is leading the way in data-driven recordkeeping.
This article explores what sets blockchain solutions apart from traditional record-keeping systems.
What is a Traditional Database?
A traditional database is a type of data structure that helps store and handle data.
The crucial thing about databases is that they allow users to get the data they need. SQL is used to query the data.
Traditional databases follow a client-server setup. Clients, which are the end-users, ask the server for specific data. The server handles these requests.
For security reasons, the client software has to be verified before it can be used. Only those with login credentials and passwords can access private databases.
What is a Blockchain Database?
Blockchain databases have many decentralized nodes.
Each node plays a role in managing the database. They all check and confirm new entries to the blockchain and can add new data.
To add something to the blockchain, most nodes have to agree.
This agreement system ensures the network’s security. Which makes it hard for anyone to tamper with the information.
Traditional Database vs Blockchain Database
Traditional databases operate within a Client-Server architecture. Users can view and modify data. This data is stored in a central database or on a centralized server.
Regular databases use a setup where one central authority controls everything. One central authority checks your credentials before granting you access to the database, where changes can be made. If someone messes with the admin, they can mess with the data.
In contrast, blockchain databases have multiple “decentralized nodes.”
Each node actively verifies new blockchain additions to ensure seamless data integration.
They’re a bit different. Instead of one authority, there are lots of independent “nodes” that play a part in managing things. Each node checks and approves new data, making sure nothing gets left out.
So, when something new is added, every node agrees on it before it becomes part of the database. This agreement makes sure no one can mess with the data—it’s super secure.
In regular databases, if you have the right access, you can mess up the data. By working together, blockchain nodes make tampering nearly impossible.
Authorized users can compromise conventional databases, but blockchain nodes use a consensus mechanism. This is a major difference between blockchain and other record-keeping methods.
CRUD vs Read and Write Operations
Functionality is another difference between blockchains and databases.
Classic databases allow CRUD—Create, Read, Update, and Delete—operations.
In contrast, blockchain users can only add data, which is permanent and cannot be changed. This addition occurs through the creation of new blocks.
Blockchain operations focus on Read and Write functions.
Historical data is immutable, highlighting that blockchain operations are Read Functions only.
This lack of alteration makes blockchain a far more secure record keeping solution.
Blockchain has a key edge over traditional databases with its real-time verification.
When a transaction kicks off on the blockchain, nodes in the network instantly confirm it.
Since blockchain can perform verification in real time, it is more efficient than legacy systems, which often take longer.
Blockchain has transformed how we store data by using a distributed ledger structure.
Blockchain is not like traditional databases, where all the data is kept in one place. Instead, the data is spread out among many nodes in the network, creating a decentralized storage system.
This not only makes data more secure but also adds redundancy, making sure we don’t lose data. It’s like having multiple copies of important files, in case one needs it.
Decentralization and Distributed Networks
One major advantage of blockchain is its decentralized nature.
Traditional systems rely on a single entity to keep track of records and verify their accuracy, which can invite inaccuracies and even fraud. Blockchain, on the other hand, uses a decentralized network of computers to perform these tasks.
Unlike centralized databases, blockchain uses a decentralized network of nodes.
This decentralization is a key part of the blockchain’s security. It allows peer-to-peer transactions, eliminates data theft, protects data privacy, avoids single points of failure, and creates a trustworthy system.
As a result, it is harder for a single entity to change the data. This makes the system safer and more reliable.
Cryptography and Security
Blockchain technology uses advanced cryptographic hash functions to secure data.
Each transaction within a blockchain is encrypted and intrinsically linked to the one before it. This creates an additional layer of protection.
By default, blockchain solutions encrypt all transmitted data. This makes data transactions far more secure than traditional methods.
Verification Process and Consensus Mechanisms
These mechanisms are there to make sure that transactions are legitimate. They make checking things safer than traditional methods, which involve central authorities or middlemen.
How Does Blockchain Maintain Its Decentralization and Transparency?
Blockchain technology uses a distributed ledger to store data across independent nodes.
Each node stores an identical copy of the blockchain database to ensure that information is never stored in a single location.
The network welcomes any number of “nodes,” or computers, from any number of sources.
When a transaction takes place on the blockchain, it is added to a group of transactions called a block.
The block is then sent out to every node in the network to be verified.
For a successful validation, the majority of nodes must accept the data in the block. A process called consensus adds the block to the existing chain of blocks after it has been checked and approved. This makes a record of the transaction that can not be changed.
Consensus ensures the security and tamper-proof nature of data on the blockchain.
To link blocks in a chain, a cryptographic hash function generates a unique code for each block. This hash serves to authenticate data and prevent unauthorized changes.
Each block in the blockchain has the hash of the block before it, which makes it impossible to change. If an older block is changed, its hash changes, which affects all blocks that come after it.
Thousands of nodes would have to verify any change, making this scenario highly improbable.
As a nutshell, the blockchain provides a trustworthy, decentralized, transparent, and unchangeable data store.
There is no need for a third party to verify or record transactions, and the data is impervious to changes.
Is Blockchain Record Keeping Secure?
Yes, blockchain is a secure technology for record keeping.
Due to its specialized design, blockchain technology is extremely resistant to tampering. It’s more secure than traditional databases.
Blockchain stores data in a decentralized ledger shared by network nodes.
To prevent tampering, the network ensures the integrity of each data block via consensus verification and encryption.
However, blockchain isn’t foolproof. One risk is losing private keys, which are crucial for accessing data. If a business loses these keys, it could be a major problem.
If too few nodes support the blockchain, it becomes an easier target for hackers. Also, businesses need specialized knowledge to handle blockchain tech, unlike centralized systems.
Blockchain has limits on the amount of data that can be transferred at a specific time. This can be a hurdle for businesses with large data needs.
Benefits of Using Blockchain for Record Keeping
Blockchain technology is unique among recording technologies in that it is both secure and trustworthy. Using blockchain for record-keeping provides several benefits:
1. Cost Reductions
Traditional record-keeping relies on third-party authorities to manage data, incurring extra expenses. In contrast, blockchain’s decentralized digital ledger eliminates the need for intermediaries, reducing costs.
Normally, only certain people can check records. On the other hand, blockchain makes everything transparent and clear for all parties involved.
2. Enhanced Security
Traditional record-keeping is vulnerable to errors and hacks because entries can be added or removed easily. Blockchain’s use of digital ledger blocks enhances security by preventing such vulnerabilities.
Traditional record-keeping limits access to authorized individuals or organizations. Blockchain allows all parties to access data, promoting transparency in agreements and data handling.
4. Eliminate Errors and Mistakes
Conventional record-keeping, often manual, increases the risk of mistakes, errors, and omissions. Blockchain’s decentralized ledger prevents hacking and manipulation, making data more secure.
Compared to conventional methods, what sets blockchains apart is decentralized control. Traditional approaches rely on a single point of control, which leaves data vulnerable to being erased, corrupted, or destroyed by anyone with access to the underlying database. Blockchain mitigates these risks by decentralizing control and enhancing overall security.
Managing Traditional Database vs Managing Blockchain Database
CRUD operations, which stand for “Create, Read, Update, and Delete,” are standard fare in conventional databases.
An administrator is in charge of the centralized management of all databases.
This individual has the ability to make adjustments to the database as necessary. Their primary role is to enhance performance and reduce redundancy in the database.
As the database grows, so does the need for daily audits and a checklist of maintenance tasks.
The process can be streamlined by having a central administrator delegate duties to other users. These tasks can range from data entry to modifications.
Databases need backup storage to handle potential issues. Important data may be lost due to data corruption or server failure.
In such situations, files can be recovered from backups. Backup processes also allow for archiving multiple versions of a database.
However, blockchain technology distributes administration tasks among network nodes using their computing power. Each node holds a complete copy of the entire blockchain.
To alter the content of a block, its hash must be changed.
Blockchain technology automatically adjusts the level of difficulty for hashing a block. An enormous amount of computing power would be needed to change the hash of all blocks.
This is only possible in a 51% attack, where a malicious actor has more computing power than the network.
This characteristic makes blockchain technology highly resistant to changes, ensuring immutability.
Immutable records contribute to transparency in the system.
Blockchain is notably fault-tolerant. Even if some nodes (computers) go offline, the remaining nodes maintain 24/7 uptime.
Blockchain transactions don’t need authoritarian permissions, making it a permissionless system.
Blockchain can serve the same purpose as a database, but with the advantages of being immutable, transparent, fault-tolerant, and able to run without the need for a trusted third party.
Reasons to Use Blockchain Technology
1. Fault Tolerance
Blockchain excels at system preservation when compared to a conventional database. Blockchain’s reliability comes from its hundreds of thousands of nodes rather than a few central servers. Even if some nodes are turned off, the overall efficiency of the network remains solid.
Every node in the network downloads a copy of the blockchain to confirm new blocks. Even changing one block requires a lot of computing power, making it secure from malicious attacks.
If you have access to the public blockchain, you can view every single transaction ever made. Unlike with traditional banks, where transfers are kept secret, blockchain makes all transactions public. This openness lets skeptics verify claims and follow the money in controversial cases.
4. Cost Reduction
Blockchain can be a cost-cutter for organizations. Transaction processing is streamlined, time spent on mundane tasks like data gathering is reduced, and reporting and auditing are made easier. Blockchain technology aids businesses financially by eliminating costly intermediaries.
If your data is stored in a single location, it could be accessed by anyone with the right credentials. As a distributed ledger with embedded cryptography, blockchain technology is well-suited to addressing this problem. Before settling on a database, businesses should conduct a thorough analysis of their requirements and consider the advantages and disadvantages of each system.
