Unraveling DeFi, Blockchain, and the Evolution of Decentralized Money

Features of DeFi

DeFi or Decentralized Finance proposes a paradigm shift in the financial sector by establishing an open, transparent, and accessible financial environment.

This novel concept uses blockchain technology to bypass traditional intermediaries like banks and financial organizations, giving individuals complete control over their assets and transactions.

DeFi comprises numerous financial services like lending, borrowing, trading, and investing, all developed on decentralized platforms. The usage of smart contracts – self-executing agreements with terms incorporated in the code – is the foundation of DeFi, allowing for frictionless and safe transactions between parties.

DeFi offers a more inclusive and democratized approach to finance by eliminating the need for intermediaries and embracing decentralization, benefiting users worldwide.

Another distinguishing feature of DeFi is liquidity pools that enable users to contribute their assets to a common pool and receive passive income through interest or fees. This mechanism encourages participation and assures that decentralized platforms have enough liquidity to conduct seamless and efficient transactions.

As DeFi evolves, it is becoming a more appealing alternative to established financial institutions, promising a brighter and more egalitarian financial future.

The Role of Blockchain Technology in DeFi

Let’s take a moment to admire DeFi’s backbone: blockchain technology, primarily Ethereum. You may be wondering what makes blockchain unique and why it is so important to DeFi’s success.

Blockchain, on the other hand, is a distributed, decentralized, and secure digital ledger that records transactions in blocks. It enables the development of trustless, transparent, and tamper-proof systems – exactly what DeFi needs!

The true strength of Ethereum blockchain technology is its ability to enable the development of decentralized applications (dApps) that run on its network. DeFi services such as lending, borrowing, trading, and investing are now feasible without the requirement for a central authority.

It also allows for the production of decentralized digital assets such as cryptocurrencies and tokens, which feed the expansion of DeFi.

The Origin of DeFi

DeFi can be traced back to the birth of Bitcoin in 2008. Although Bitcoin is not a DeFi application in and of itself, it does lay the groundwork for decentralized financial services by showcasing the possibilities of a decentralized, peer-to-peer payment system.

However, the ultimate birth of DeFi occurred with the launch of Ethereum in 2015. DeFi’s development and expansion were aided by Ethereum’s release of smart contracts and the ability to construct decentralized apps (dApps) on its platform.

Charting DeFi’s Development: Key Milestones

DeFi has seen important achievements that have brought it to the forefront of the financial world in its relatively short history. Among the major landmarks are:

  • MakerDAO is the first decentralized autonomous organization (DAO) to create the stablecoin DAI, which is pegged to the US dollar. This was the start of DeFi’s venture into lending and borrowing.
  • Uniswap’s launch (2018): Uniswap, a decentralized exchange (DEX), transformed the way users trade cryptocurrencies by utilizing liquidity pools rather than traditional order books, resulting in a more efficient and decentralized trading experience.
  • DeFi saw significant growth in 2020, with total value locked (TVL) on DeFi platforms jumping from over $1 billion at the start of the year to more than $14 billion by the end of 2020.
  • Mainstream adoption: The success of DeFi has piqued the interest of major financial institutions, with many investigating the feasibility of incorporating DeFi solutions into their services.

Is DeFi crypto’s version of a stock exchange?

While there are similarities between DeFi and stock exchanges, they are not the same.

DeFi is a broader idea that includes a variety of financial services, such as decentralized trading platforms similar to stock exchanges.

However, it goes beyond trading to include lending, borrowing, and other financial services enabled by decentralized technology. Let’s look at how they differ in the DeFi ecosystem.


The core notion of decentralization is the most significant distinction between DeFi and regular stock exchanges.

Traditional stock exchanges are centralized institutions that govern and regulate the trading activity, whereas DeFi platforms, including DEXs, run on decentralized networks such as Ethereum, allowing users to trade with one another directly.


Traditional stock exchanges rely on middlemen to enable transactions, such as brokers, clearinghouses, and custodians.

Smart contracts, on the other hand, are used by DeFi platforms to automate and secure transactions, removing the need for intermediaries and lowering associated expenses.

Inclusion and Access

Traditional stock exchanges impose access barriers like minimum investment amounts, accreditation requirements, and geographical restrictions.

However, DeFi systems are open and available to anybody with an internet connection, fostering financial inclusion and democratizing access to financial services.

Trading Hours

Traditional stock exchanges have set trading hours, whereas DeFi platforms and DEXs offer 24/7 trading, allowing users to trade whenever they want.


Because all transactions are recorded on a public blockchain, they are easily verifiable and auditable, DeFi platforms and DEXs provide greater transparency than traditional stock exchanges.

Centralized vs. Decentralized Finance (CeFi vs. DeFi)

CeFi vs. DeFi

Centralized Finance (CeFi) and Decentralized Finance (DeFi) are two separate approaches to financial services, each with its own set of benefits and drawbacks. Let’s look at their main distinctions.

Governance and Control

CeFi operates under centralized control, which means that banks, traditional finance, and financial institutions are in charge of the transactions and services they offer. These bodies are in charge of making decisions, enforcing rules, and regulating the flow of money in the system.

This centralized governance model ensures compliance with existing laws and regulations by providing a structured and regulated environment for financial services.

DeFi, on the other hand, uses blockchain technology to build decentralized platforms that give consumers more control over their assets and transactions. Smart contracts and decentralized governance models, which are often based on consensus algorithms, are used to enforce decisions and norms.

This decentralization provides greater autonomy and flexibility, but it also implies that DeFi platforms may be less regulated and prone to greater dangers.

Agents of distribution

Centralized exchange relies on intermediaries to enable transactions, such as banks, brokers, and payment processors. Account administration, payment processing, and transaction execution are just a few of the services offered by these intermediaries.

While this paradigm provides convenience and dependability, it also adds inefficiencies, greater costs, and significant delays in transaction processing.

DeFi eliminates the need for intermediaries by automating and securing transactions with smart contracts. Smart contracts are self-executing contracts with terms and conditions encoded straight into code. These contracts can automatically facilitate, verify, and enforce contract fulfillment, eliminating the need for middlemen and associated fees.

DeFi platforms can provide faster, more efficient, and less expensive financial services by eliminating intermediaries.

When compared to CeFi institutions, DeFi platforms provide more transparency. DeFi platform transactions are recorded on public blockchains, making them easily traceable and auditable. This transparency ensures that users may rely on the platform’s operations and check transaction accuracy without the need for third-party audits.

CeFi institutions, on the other hand, have private, centralized ledgers, making it harder for users to obtain insight into their activities. Furthermore, CeFi institutions are not obligated to disclose all of their operations, which can lead to inconsistency and potential conflicts of interest.


DeFi systems are open and available to interested investors with an internet connection, lowering entry barriers and boosting financial inclusion. Users can use DeFi services regardless of their location, income, or financial status, allowing underserved groups to engage in the global financial system.

CeFi services, on the other hand, have eligibility requirements and regional restrictions that can preclude potential users. To obtain CeFi services, investors may need to fulfill certain income requirements, have a certain credit score, or live in a given nation.

These entrance obstacles can impede financial inclusion while also perpetuating existing inequities in the financial system.

Safety and custody

CeFi institutions are often custodians of their users’ assets, storing and managing funds on their behalf. Because consumers do not have to handle their assets directly, this custody model can be convenient. It does, however, introduce a single point of failure, leaving CeFi institutions vulnerable to hacking, fraud, and mismanagement.

DeFi systems, on the other hand, allow users to keep control of their assets by using non-custodial wallets and smart contracts. Users are in charge of managing their private keys, which allow them to access their funds.

This non-custodial architecture decreases the possibility of centralized failures while also requiring users to assume greater responsibility for the protection of their assets.

Advantages of DeFi

DeFi advantages

DeFi is crucial for various reasons, including its potential to change the global financial system and yield enormous advantages. Among the many benefits of DeFi are:

Financial Democratization

DeFi has the potential to democratize access to financial services by reducing entry barriers and creating a more inclusive financial environment.

Cost Cutting

DeFi platforms can help cut financial service costs by eliminating intermediaries and automating procedures with smart contracts. Traditional financial systems frequently involve several middlemen, such as banks, brokers, and payment processors, which can result in higher fees and longer transaction times.

DeFi can provide more efficient and cost-effective financial services by eliminating these intermediaries.

Better Security and Control

Through non-custodial wallets and decentralized protocols, DeFi systems allow users to keep control over their assets. This additional control has the potential to lower the danger of centralized failures, hacks, and mismanagement which are common in traditional financial organizations.

Furthermore, DeFi platforms frequently include blockchain technology, which, due to its decentralized and tamper-resistant nature, provides additional security and transparency.

Financial Ingenuity

DeFi has fostered a new wave of financial innovation by providing a platform for new financial products and services. DeFi projects’ open-source nature encourages cooperation and experimentation, which leads to the invention of novel financial instruments and application cases.

Decentralized lending and borrowing platforms, tokenized assets, yield farming, and decentralized insurance products are among the examples.

Now that you’re familiar with the concept of smart contracts and their real-world applications, it’s time to look deeper into why Ethereum is the best choice for smart contract creation.

Ethereum: The Ideal Smart Contract Development Platform


Ethereum has established itself as a prominent platform for smart contract creation; nevertheless, what makes it the best choice for businesses? Here are several major features that distinguish Ethereum:

Developer Community

Ethereum has a large and active developer community that is always contributing to the platform’s growth and enhancement. This dynamic ecosystem encourages creativity and offers a wealth of tools, making it easier for newbies to learn and build on the platform.

Robust Ecosystem

Ethereum’s ecosystem contains a variety of tools, frameworks, and libraries that make building and implementing smart contracts easier. This comprehensive bundle of materials assists developers in overcoming obstacles and expediting the development process.

Native Cryptocurrency

Ether (ETH) is the Ethereum platform’s native money, which supports smart contract execution and incentivizes developers to create and maintain decentralized apps (dApps).

Now that we’ve established Ethereum’s dominance in the smart contract ecosystem, let’s move on to Solidity, the programming language that enables Ethereum development.

Solidity: Ethereum’s Powerful Programming Language


Solidity is the primary programming language used on the Ethereum platform to create smart contracts. It is designed expressly for blockchain and smart contract development and has distinct features and capabilities that set it apart from other languages.

Here are some key features of Solidity:


Solidity is an object-oriented language that allows developers to write modular and reusable programs. This functionality facilitates the organization and maintenance of complex smart contract projects.

Static Typing

Solidity is a statically typed language, which means that variable data types are explicitly defined during compile time. This feature aids in the detection of potential mistakes early in the development process, hence improving the overall security and reliability of smart contracts.

Similarities to JavaScript

Solidity contains syntax similarities with JavaScript, making it easier for developers who are already familiar with JavaScript to learn and adapt to the language.

Contract Structure

Smart contracts in Solidity are arranged into a contract structure, which comprises features like state variables, functions, events, and modifiers. Understanding these aspects and their interactions is critical for the effective development of smart contracts.


Contract inheritance is supported by Solidity, allowing developers to build new contracts that inherit properties and methods from existing ones. This feature encourages code reuse and modularization, resulting in smart contract projects that are more controllable and organized.

Error Handling

To manage exceptional conditions and ensure that contracts execute only when particular requirements are met, Solidity provides error handling features such as ‘require’, ‘assert’, and ‘revert’. Implementing adequate error handling is crucial for smart contract security and stability.

Gas Optimization

Smart contracts on Ethereum consume ‘gas,’ which translates to transaction fees paid in Ether. Developers of Solidity could optimize their code to reduce gas usage, making smart contract interactions more cost-effective for users.

Best Security Practices

Writing secure smart contracts is critical in the realm of blockchain. Familiarizing yourself with common security patterns, such as the ‘Checks-Effects-Interactions’ pattern, as well as maintaining up to speed with Solidity’s latest security guidelines, can assist you in building robust and safe smart contracts.

Setting Up Your Ethereum Development Environment

Before getting into smart contract development, it’s critical to set up an appropriate development environment. Having the correct tools at your disposal can help you to streamline your process and increase your productivity.

Here is a list of crucial Ethereum development tools and resources:

Integrated Development Environment (IDE)

An IDE, such as Remix or Visual Studio Code, provides a user-friendly interface for creating, testing and deploying smart contracts. These IDEs provide syntax highlighting, auto-completion, and debugging features, making development easier and more efficient.

Solidity Compiler

To compile your Solidity code into bytecode that can be executed on the Ethereum Virtual Machine (EVM), you’ll need a Solidity compiler, such as ‘solc’. Most IDEs come with a built-in compiler or offer plugins to incorporate one.

Truffle Framework

Truffle is a popular Ethereum development framework that makes smart contract compilation, deployment, and testing easier. It also includes capabilities such as migrations, network management, and connection with well-known front-end technologies such as React and Angular.


Ganache is an Ethereum development personal blockchain that allows you to run tests, issue commands, and view state while controlling the execution environment. It’s a fantastic resource for mimicking blockchain interactions during development and testing.


MetaMask is a browser extension that acts as an Ethereum wallet and a bridge between your browser and the Ethereum network. It allows you to communicate with smart contracts and dApps without having to run an entire Ethereum node.

Learning tools

Solidity documentation, Ethereum Stack Exchange, and online courses like ConsenSys Academy or CryptoZombies are all excellent tools for learning and troubleshooting while working on Ethereum.

Smart Contract Scaling: Integrating with Decentralized Applications (dApps) and Beyond

As your knowledge and comfort in smart contract development expand, you may want to consider integrating your smart contracts with decentralized applications (dApps) and scaling them to fit your business’s needs.
Here’s what you should know:

Creating Decentralized Applications (dApps)

Decentralized applications (dApps) are programs that operate on decentralized networks such as Ethereum, integrating the power of smart contracts with user interfaces to offer interesting and secure digital experiences.

Integrating your smart contracts with dApps can help you open up new business prospects while also improving user experience.

Interoperability with Other Protocols

As the blockchain ecosystem evolves, new protocols and platforms emerge, allowing for cross-chain interactions and greater functionality. Learning how to combine your smart contracts with various blockchain protocols will assist you in staying ahead of the curve and entering new industries.

Layer 2 Scaling Solutions

As your smart contracts grow in complexity and popularity, you may encounter issues with transaction throughput and gas expenses. Layer 2 scaling solutions such as Optimistic Rollups and zk-Rollups can assist you in overcoming these difficulties by offloading computation and storage from the main Ethereum network, resulting in faster and cheaper transactions.

Upgradability and Governance

As the complexity and user base of your smart contracts expand, adding upgradability and decentralized governance methods becomes crucial. These characteristics enable your smart contracts to adapt and evolve over time, ensuring long-term viability and harmony with your company objectives.

Security Audits and Best Practices

As your smart contracts manage more valuable and vital business functions, their security becomes increasingly important. Regular security audits, adherence to best practices, and being current on the latest security research can assist you in maintaining resilient and secure smart contracts that can survive future threats.

Using web3.js and Creating a Simple Web Interface to Interact with Your Smart Contract

You can interact with a deployed smart contract using libraries such as web3.js, which provide a straightforward way to communicate with the Ethereum blockchain. We’ll show you how to make a simple web interface for users to interact with a smart contract in this guide.

We’ll utilize the SimpleMessage contract we built before in this example.

Create your project

Make a new folder for your project and run npm init to get it started. Run the following command to install the essential dependencies:

npm install code

Connect to the Ethereum network

Make a file called index.js in your project folder. Set up a connection to the Ethereum network using web3.js in this file:

index.js file

Make a basic web interface

In your project folder, create an HTML file called index.html with the following structure:


Use web3.js to interact with the smart contract

To communicate with the smart contract, add the following functions to your index.js file:

async func to index.js

Serve your dApp

To test your dApp, use a simple HTTP server such as http-server. Using npm, install it globally:

npm global

Then, in your project folder, execute the server: http-server

To interact with your dApp, open your browser and go to http://localhost:8080.

Using web3.js, you’ve now constructed a simple web interface for people to interact with your smart contract. As needed, this basic configuration can be enhanced and adapted to accommodate more complicated smart contracts and user interactions.

The Ultimate Guide to Blockchain Development – [Plus use cases]

Before Covid, the instant surge in the blockchain market attracted the attention of everyone, even the stock marketers. It was a considerable business that gained the trust of people to invest. But, only a few know in-depth knowledge of blockchain development and its work. 

Today, the market is all about how information is getting transferred. Blockchain has changed how it delivers that information as it offers immediate, shared, and transparent information that authenticated network members can only access. Not only this, there is much about blockchain, like decentralization, unanimous, immutable, and others.

distributed ledger technology

As digitization is taking over the global market, blockchain has emerged as one of the new-age technologies that are helping businesses to reach new heights. It will be fantastic to know how big is the blockchain market and how it is growing. 

As per the research, the size of the global blockchain technology market was USD 5.92 billion in 2021, which will grow tremendously by 2030. Below are the stats that will prove it.

As investing in blockchain technology is legal in countries. People are investing in it and creating new opportunities for market growth. Statista says global spending on blockchain solutions accelerated from 4.5 billion to 6.6 billion in 2021, estimated to rise to $19 billion (approx) by 2024. That’s a huge number!

blockchain investment

Well, these are the stats that are important to get to understand more about Blockchain. But for those not aware of the Blockchain and its benefits, you have landed on the right page that will help you explore blockchain technologies and their use cases.

What is Blockchain? Understanding the hype around it…

You can compare a blockchain with a distributed database whose data and crucial information is shared across the network globally. It is a secure way to store transaction records. All the information is stored in a digital format, making it preferable to store and share cryptocurrency, such as Bitcoin. 

It is just like a database with a critical difference: the data structure. Unlike a typical database, Blockchain gathers information and groups them into blocks. Each block has its storage capacity; once filled, they are closed and will get linked to the previously filled block through cryptographic hashing. It will create a unique secure code that will tie into the next page or block, creating a chain of blocks or a blockchain.

This creates a chain of blocks, thus getting its name (Blockchain).

chain of blocks

But, why does blockchain come into the picture?

Today, global transactions between nations somehow define the legal and political structure. These transactions, contracts, and records need to be secured. The way we have regulated those transactions has to change and need modifications in term of security. This is where blockchain came into the picture and has helped solve this problem. 

Blockchain is an open, distributed ledger that records those transactions between two parties efficiently and verifies who is making the transaction. 

Blockchain ledgers are public and designed with robust security measures, making them a fantastic technology for almost every sector. Today, every sector is using blockchain technology to grow their business securely. 

Isn’t it fantastic technology? 

Have you ever wondered how this technology came into the picture and how it has evolved? Let’s dig deeper into its history.

History of Blockchain

Blockchain is not a new technology, though. It has an exciting history that everyone having an interest must know. We have mentioned a timeline from the beginning of the blockchain. In 1991, Stuart Haber and Wakefield Scott Stornetta introduced the first concept of blockchain. They introduced the idea of a cryptographically secured chain that is now referred to as blocks. 

But this technology has just started getting traction and is getting global recognition. 2008 marked a pivotal point when Satoshi Nakamoto introduced an established model and planned application for blockchain technology.

We will discuss the entire evolution below.

How does a transaction add to a blockchain?

If we see the below image, the process seems to be simple. But, it is a complex task.

blockchains work

Whenever we have a new transaction, a new block will be added to the blockchain. For this, several nodes having the identical blockchain will run algorithms that will evaluate, verify, and process the history of the blockchain. 

If most nodes verify the history and the sign of the new block, it will be accepted into the ledger. Now, the new block is added to the blockchain. 

But, if the block does not process as per the consensus (set of rules by which a blockchain network operates and validates the block’s information), it will get rejected. 

In this way, the blockchain functions as distributed ledgers without needing a central or unifying authority to validate the blockchain transactions, making it highly secure.

Why adopt Blockchain?

We needed a bigger picture to safeguard highly-confidential transactions, keep records safe, and eliminate vulnerable attacks. This is when the Blockchain enters. Several reasons can influence you and your business to opt for blockchain technology. If you are not using Blockchain, then you must read its benefits.

  • Greater trust- Blockchain has enabled everyone to get accurate and timely data. Even though your confidential data is on the network, only network members can access it if they have proper access.
  • Greater security- once the information is on the Blockchain, no one can delete that record. Even the system administrator cannot hamper the stored information. It will be logged what actions are being taken on the data.
  • Improved efficiency- by eliminating the reconciliation of unnecessary records, Blockchain improves the efficiency of the transactions. For speedy transactions, it uses some rules, known as a smart contract that is stored within the Blockchain.
  • Transparency- most blockchains are open-source, allowing everyone to view their codes. Due to enhanced transparency, auditors can review cryptocurrencies for security. There is no fixed authority or authorized person who is allowed to make the code change. If the majority of the users within the network support the change, the code will be updated. 
  • Decentralization- there is no central location for the information. Instead, the Blockchain is copied across the network. A single block change in the Blockchain will reflect on each network, making it difficult to tamper with the Blockchain. 
  • Reduced costs- Blockchain reduced unnecessary costing by eliminating the need for the third party to verify the transactions and their associated costs. Unlike the traditional banking system, where they charge for their transactions, there is nothing like this with the bitcoin transactions. 

But, blockchain has a concept of “gas fees” given to the miners as compensation for the computing power they use to verify any transaction. This payment is done in the blockchain’s native cryptocurrency. This cost is mandatory, and you cannot make transactions without paying gas fees. 

Well, this is not the end of the benefits anyone can leverage of Blockchain. Today, Blockchain is helping many sectors in the market to help their businesses grow.

It has created many attractive opportunities in the various industries. 

blockchain opportunities


Drawbacks of Blockchain

Despite several benefits, everyone must keep some significant drawbacks in mind while dealing with blockchain technology.

  • Technology cost- though there are no intermediary charges while transactions with blockchain. But, this technology is costly due to its network’s access. Blockchain has a vast network, and being a part of that is costly. Another cost is for bitcoin mining, which means the process where a bitcoin is awarded to a computer that solves a complex algorithm. This mining process includes solving complex math problems to create new bitcoins that consume much energy. This requires a special system that is too costly.

Due to this issue, many solutions are rising to help reduce such computational costs of making transactions and mining the required data within the blockchain network. 

  • The efficiency of data and speed- bitcoin is considered slow as the PoW system takes around 10 minutes to add a new block to the blockchain. This, in turn, reduces the number of transactions per second. Many developers have been working for years to improve this situation of deployed speed. 
  • Illegal activity- somehow, blockchain supports and validates illegal activity around the network. The most famous example of illegal activity is the Silk Road, an online dark web, money laundering, and others. To overcome this problem, some government has imposed regulations and background checks on the new user’s account. 
  • Regulations- some crypto has regulations imposed by the government of specific regions. Some countries have banned dealing with and owning cryptocurrencies. But, out of the box, PayPal has allowed the ownership of cryptocurrencies on its platform, eliminating the imposed regulations and making it easier for people to make blockchain transactions.

Due to the increased popularity of blockchain over time, new variations of blockchain have been introduced to cater to different market needs. Let’s see what different types of blockchains available are.

If you look closely, these are not drawbacks but seem like barriers to taking blockchain down. Some other barriers to be considered are-

Types of Blockchain networks

Blockchain networks are of different types-

blockchain networks

Public blockchain networks

In such networks, blockchain is open and accessible to everyone. In simple words, no permission is required to access such bitcoin networks. You only need to download and install the software on your system, and your system will become a node within the blockchain public network. Then you can use your system for mining, verifying transactions, and others.

Private blockchain networks

A single entity handles such blockchain networks. These networks have restrictions on who can access them. Leading companies decide whether o constrict or expand the network. Such networks are also known as enterprise blockchains.

Hybrid blockchain networks

Hybrid means combing the benefits of both the public and private blockchain networks. To access the data and other operations on hybrid networks, you need permission for some tasks and do not need permission for others. With a network comes greater flexibility. You can access it anytime, along with some restrictions to ensure high security.

Consortium blockchain networks

A consortium blockchain is also popular as a federated blockchain. Unlike a hybrid network, this network is handled by multiple companies. It has a semi-closed ecosystem rather than having o

Just one. This network comes with high transactional speed and scalability. This is why consortium blockchain networks are highly decentralized. Not only this, you can still be a part of both private and public blockchain networks. 

Blockchain security for the enterprise

To create a blockchain application, you will require many technologies to be combined and work together. Thus, to ensure security, you must implement best security practices at each technology stack. This is how you can manage access and permissions to different types of nodes. 

Maintaining security is not that easy. You must work on strategies and follow the best practices to develop a secured enterprise blockchain solution. Below are some security controls you can include within your enterprise-level blockchain solutions.

  • IAM (Identity and access management)
  • Key security management
  • Data or block privacy
  • Secure and safe communication
  • Smart contract security
  • Transaction endorsement

Handling strong security is not a single-man job. You will require cross-skilled professionals who can efficiently design a compliant solution for your business. 

Blockchain security is a complex structure, as shown below.

Blockchain security tips and best practices

Designing security strategies can be complex as you must consider several factors. So, make sure that you consider asking the following questions while designing your strategy. It will help you to come up with the right security solution.

  • On what governance model can any organization join the blockchain network?
  • What type of data do you want to store on the blockchain? Does it require additional security?
  • What should the regulatory requirement be included, and how to ensure their working?
  • How to manage different identities available on the network? 
  • How do encrypt the blocks?
  • How to manage and revoke keys?
  • Specify the disaster recovery plan for the blockchain participants.

However, the questions are unlimited. You must stay focused and consider every minute detail while designing a security solution. It is essential as different enterprises across the globe are using blockchain. Blockchain has helped various sectors in different ways.

To know more about how blockchain has contributed to the market, we will explore its use cases in those sectors.
