Blockchain is the future of data science. It’s a decentralized ledger that stores an ever-growing list of records called blocks in a secure and encrypted format. These blocks are then linked together forming a chain of links, hence the name blockchain. Blockchain provides benefits such as giving transparency to data in a manner that is verifiable, immutable, and tamper-proof.

Blockchain in Data Science

The top benefit of using blockchain for data science is that it provides security to data and prevents tampering with records. Blockchain also provides transparency by allowing all participants within the network to see any change made to a record. This allows for the use of it in various industries such as finance, healthcare, education, etc. The article focuses on discussing the benefits of blockchain for data science.

Let’s start discussing each of these topics in detail.

What is Blockchain? 

Blockchain is the world’s most popular and fastest-growing technology. It has been used in many industries, such as finance, supply chain, healthcare, and more. Blockchain is a digital ledger that records transactions on a distributed public database. It is also called “distributed ledger technology” or “DLT”. The blockchain consists of blocks that are linked together and secured with cryptography. The concept was conceptualized by an anonymous person or group named Satoshi Nakamoto in 2008 and implemented the following year as a core component of bitcoin where it serves as the public ledger for all transactions on the network. Thus, blockchain technology made it possible to create a digital currency without any central authority or middleman.

Features of Blockchain:

  • Decentralized: The blockchain network has no single person looking after the network, instead a group of nodes is responsible for maintaining the network.
  • Enhanced Security:  As the blockchain network is decentralized so no one can change the characteristics of the network for their benefit and using encryption adds another layer to the security of the blockchain.
  • Transparency: Every node in the blockchain network has a copy of the digital ledger and to add a transaction every node needs to check the validity of the transaction. If the majority of the node thinks that the transaction is valid only then the transaction can be added to the block. Thus, making the entire network transparent and corruption-proof.
  • Distributed ledgers: The ledger on the blockchain network is maintained by all the nodes. So there is no single point of failure. Even if one node fails others nodes have the same copy of data so the network continues to function.
  • Faster settlement: Blockchain offers faster settlement in comparison to traditional banking services. This helps to transfer money relatively faster using blockchain.

What is Data Science?

Data science is a scientific approach to analyzing data. It includes a range of techniques for collecting, storing, analyzing, and visualizing data. It also includes the development of new algorithms that can be used to analyze data. Data science focuses on past data, present data, and future predictions. 

Features of Data Science:

  • Data collection: This involves extracting relevant information from raw data. It can be done by using different methods like web crawling, scraping, and crawling databases.
  • Data storage: This involves storing the collected information in a database or an online repository.
  • Data analysis: The process of examining the collected information in order to extract meaningful insights.
  • Data visualization: Visualizing the collected information in order to understand it better.

Relationship Between Blockchain and Data Science

Blockchain and data science are two of the most disruptive technologies in recent years. They have the potential to change all sectors of the economy, including the finance, healthcare, and supply chain management industries. Data science is a valuable tool in decision-making and predictive analytics, especially when paired with blockchain technology. It can help businesses understand trends that they otherwise might not have seen.

  • Blockchain stores and verifies data, and data science analyzes this data to derive insights into different data segments.
  • Due to the blockchain’s distributed and decentralized nature, the data is consistent across the network, thus data science can function effectively to generate predictions, and take decisions from the data.

Blockchain Impact on Data

The Blockchain has the potential to transform data storage, so it’s important to understand the implications of this technology.

  1. No third-party verification of data required: In Blockchain every node on the network maintains a copy of the ledger and a new transaction is added to the block only after it is validated by the majority of the nodes on the network.
  2. Smart contracts for transactions: Smart contracts are computer protocols designed to digitally facilitate, verify, or enforce the negotiation or performance of a contract. They are self-executing pieces of code that automatically execute when certain conditions are met (i.e., when all parties fulfill their obligations). One of the most common use cases for smart contracts is real estate transactions where they enable buyers and sellers to transact without any middlemen or brokers involved.
  3. Immutable data structures: As every node on the network maintains a copy of the ledger, the data is secure and immutable on the blockchain. When the data is changed by an intruder, the change should be validated by the majority of nodes on the network to be added to the ledger. 
  4. The high degree of control over data: Blockchain enables users to have a higher degree of control over data where they store data, which affects the accessibility and availability of the data.

Top 10 Benefits of Blockchain for Data Science

Below are the top 10 benefits of using Blockchain and Data Science together:

1. Enables Data Traceability

Blockchain is a decentralized system of records that can’t be altered or hacked. It can be used to store data in an immutable way and make it easier to trace, ensuring the integrity of the data.
One of the benefits of blockchain for data science is that it enables data traceability. This means that you can always know where your data came from and where it went to. The blockchain also ensures that no one has tampered with your data, which is quite useful when you want to ensure accuracy and reliability in your research.

2. Allows for Real-Time Analysis

Blockchain is a new technology that is revolutionizing the way we do business. It can be applied to any industry and has the potential to change how we work, live, and interact. As a distributed ledger, blockchain provides a way for people who don’t know or trust each other to share information with confidence. Transactions are stored in blocks that are linked together in chronological order inside of chains. This makes it possible for people to make sense of data without a central database or third-party verification. Blockchain technology allows for real-time analysis by allowing users to input data into the system and then instantly see what happens with it as it moves through the system. Harder to fake, expensive, and has low data integrity. Easier to manipulate, cheap, and has high data integrity.

3. Makes Data Sharing Easier

Blockchain has created a new way of managing data. This type of information is stored in blocks and each block has a timestamp, which makes the data tamper-proof. The blockchain prevents data from being edited or erased so it can be used for future analysis and research.

4. Ensures High-Quality Data

By using a decentralized ledger and hourly updates, blockchain technology creates an issue-free world of data. Blockchain is an incorruptible digital ledger that stays updated on the fly and contains a record of every transaction that has ever happened, giving it a vast amount of trust. Blockchain technology ensures high-quality data feed. By using a decentralized ledger and hourly updates, Blockchain technology creates an issue-free world of data.

5. Enhanced Data Integrity

Blockchain-enabled data integrity is a breakthrough technology that is going to change the way we do business. This is a decentralized ledger system that ensures data cannot be tampered with or changed without leaving an immutable record of the change.

6. Encrypted transaction

The blockchain provides an immutable record of transactions between two parties without the need for a central authority to verify the transaction. This means that once something has been recorded in the blockchain, it cannot be altered or erased.
Each block in the blockchain contains information about its previous block (parent), which makes it possible to trace any transaction back to its origin.

7. Builds Trust

Blockchain has many use cases that have been explored, but one of them is its ability to build trust. Blockchain can help to create a more transparent system that relies on the community more than any single person within it. The blockchain gives consumers access to the data they want to see and the power to control their information. It also provides more transparency in supply chains, greater security for smart contracts, and self-executing property deeds.

8. Data Lakes

Organizations’ information is usually stored in data lakes. Blockchain uses the source of the data to record it in a specific block with a specific cryptographic key. 
Blockchain is a secure, transparent, and fast way to ensure that anything of value can be traded in an efficient manner. Blockchain allows for the transfer of ownership without relying on a trusted third party. 

9. Make Predictions (Predictive Analysis)

Blockchain data, just like other types of data, can be analyzed to reveal valuable insights into behaviors, and trends and as such can be used to predict future trends. It can be applied to topics such as supply chains, property management, and online advertising.

10. Cost reduction

It has helped in cost reduction by reducing costs associated with third parties, intermediaries, and brokers. It also helps in increasing the speed and transparency of transactions, which reduces costs associated with compliance.

How Blockchain Can Help Big Data?

1. Take Control of Data Sharing

A blockchain-based Big Data solution would allow providers to share records with any other sector with an interest without the risk considerations that come with a network of separate data silos. Data from data studies can be stored on a blockchain network in this case.  Connected via encrypted channels and protected by advanced cryptography, the records are difficult to forge or change. The idea of a decentralized future has been around for some time now. However, many people still don’t know what it means for the society of today. Blockchain is the underlying technology that can help us move from a centralized system to a decentralized one in the future.

2. Data Monetization and Sharing

Combining blockchain and big data can help to advance the way data analytics is shared and monetized. Data is the new oil and the more data you have, the more valuable it becomes. Big data is one of the most valuable resources in today’s world. It can be used to predict future trends and make decisions accordingly. Combining blockchain and big data can help to advance the way data analytics is shared and monetized. 

3. Improve Data Security

The data security that exists within the blockchain is perhaps the most significant benefit that this technology provides to Big Data analytics. Data security is one of the most important aspects of any business because it affects all aspects. It is important to understand that data security is not only about preventing the loss of data but also about preventing unauthorized access to data and securing the systems that store and process the data.

4. Streamline Data Access

Another way that blockchain can help Big Data and analytics is by making data access more efficient. Data access is a major hurdle in the process of data analytics. With blockchain, data access will be more streamlined and efficient.

5. Preventing Fraud

Financial institutions can check every transaction in real-time thanks to blockchain technology. Fraud has been a problem for financial institutions for a long time.
