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.

Decentralization

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.

Intermediaries

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.

Transparency

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.
Accountability

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.

Availability

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.

Traditional financial systems frequently contain constraints such as minimum investment amounts, credit scores, and regional restrictions, which can prevent a huge section of the world’s population from gaining access to financial services.

DeFi systems are open and available to anybody with an internet connection, fostering financial inclusion and empowering people to participate in the global financial system.

Enhanced Accessibility

DeFi platforms are accessible 24/7, allowing users to access financial services at their convenience. Traditional financial systems, such as banks and stock exchanges, frequently have limited operating hours, which might limit service availability.

The availability of DeFi platforms around the clock provides customers with greater freedom and can promote more smooth worldwide financial transactions.

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.

Compound is yet another prominent DeFi lending and borrowing platform that allows users to supply and borrow multiple cryptocurrencies. For decentralized decision-making, it employs its native governance token (COMP).

SushiSwap

SushiSwap is a DEX and yield farming platform that provides services similar to Uniswap but with added features like Onsen (custom liquidity pools) and BentoBox (optimal yield techniques). It governs using the SUSHI token.

MakerDAO

MakerDAO is a decentralized credit platform that enables users to create the DAI stablecoin by encrypting collateral in smart contracts. It also provides a decentralized governance mechanism through the use of its MKR coin.

Synthetix

Synthetix is a DeFi platform that allows users to create and trade synthetic assets, allowing them to obtain exposure to other markets without owning the underlying assets. The SNX token is used for collateralization and governance.

Understanding Risks and Ensuring Security of the DeFi Minefield

Before you headfirst into Decentralized Finance lending, remember that it, like any investment, comes with its set of hazards. The value of cryptocurrency can fluctuate, and smart contract faults or hacks are always a risk.

However, with proper research and caution, DeFi lending can be an excellent way to put your crypto asset holdings to work and make some real passive income.

Security Flaws in Smart Contracts

Smart contracts are used by DeFi platforms to automate transactions and enforce agreements. Smart contracts, however, are still vulnerable to coding faults and weaknesses that hackers can exploit.

Users should look for platforms with certified smart contracts and a history of secure operations to mitigate this risk.

Impermanent Loss

Liquidity providers in AMM-based DEXs face the danger of impermanent loss. It occurs when the relative price of assets in a liquidity pool changes, resulting in a decline in the value of a user’s deposit.

Users might consider investing in stablecoin pairs or using advanced AMM platforms with greater risk management capabilities to limit impermanent loss.

Risk of Liquidation

Users must offer collateral while borrowing assets through DeFi lending networks. If the collateral’s value falls below a specific threshold, the user’s position may be liquidated, resulting in a loss.

Users should maintain a healthy collateral ratio and closely monitor their positions to prevent liquidation risk.

Regulatory Risk

As the Decentralized Finance industry expands, governments may enact new regulations that have an impact on the ecosystem.

Users should be aware of any regulatory changes that may have an impact on their DeFi investments and alter their plans accordingly.

Risks of Centralization and Governance

Some DeFi implementations retain centralization aspects, such as admin keys or centralized oracles, which could introduce possible points of failure or manipulation.

Platforms with strong decentralized governance and security measures should be sought after by users.

Platform and Token Risks

DeFi coins’ value can be variable, and some platforms may underperform or fail. Users should diversify their assets across several platforms and tokens and undertake rigorous research before investing to reduce platform and token risks.

  • Users should choose trustworthy platforms with a proven track record and audited smart contracts to assure security and mitigate dangers in Decentralized Finance.
  • For further security, they should secure their private keys and employ hardware wallets.
  • Use risk management measures like diversification and keeping a healthy collateral ratio.
  • Keep up to current on legislative changes, platform updates, and market circumstances.
  • When investing in fresh or unproven systems and tokens, proceed with caution.

  • Insurance: Insurance businesses can use smart contracts to automate the claims process, ensuring prompt reimbursements and lowering the risk of fraud.

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

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

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:

Object-Oriented

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.

Inheritance

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

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

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.

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

Before COVID-19, the instant surge in the blockchain market attracted the attention of everyone, even stock marketers. It was a considerable business that gained the trust of people to invest. However, only a few have 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.

Investing in blockchain technology is legal in some 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 it 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 needs modifications in terms 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

Image Source

Whenever we have a new transaction, a new block will be added to the blockchain. For this, several nodes having 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 log 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 costs 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 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. However, 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 a lot of energy. This requires a special system that is too costly. 

bitcoin energy consumption

Due to this issue, many solutions are rising to help reduce the 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 governments have 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-

barriers to blockchain

Types of Blockchain networks

Blockchain networks are of different types-

blockchain networks

Image Source

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 combining 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 structure

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 do you 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.

Blockchain use cases

Blockchain is everywhere, and people willingly invest in it due to its rising economy. Today many companies are using blockchain technology to help them reduce additional transaction costs, and improve efficiency, speed, and transparency.
