Best Practices for Designing and Developing Fintech Apps Using Blockchain Technology

fintech apps using blockchain technologyFinancial technology or fintech is a burgeoning industry that seeks to make financial systems more efficient and accessible for all users. With the increased demand for faster transactions and greater security, leading-edge technologies like blockchain are gaining fast adoption. Through the use of decentralized networks, blockchain-based fintech apps, also known as decentralized finance or (DeFi) apps, are providing a secure and efficient platform for users to transact.

At present, the fintech blockchain market is valued at $6.2 billion and is projected to reach a value of $36 billion by 2028.

In this blog post, we will look into different types of fintech apps that can be developed with blockchain technology and some best practices to follow while designing and developing them.

Types of Fintech Apps Developed with Blockchain Technology

  • DeFi Banking Apps

Decentralized finance (DeFi) banking apps offer users the ability to access a variety of financial services without the need of traditional banking institutions. These apps enable users to store their money in digital wallets, transfer funds between accounts, purchase insurance, and much more.

  • Lending/Borrowing Apps

Blockchain-based lending and borrowing apps allow users to access credit by providing collateral in the form of cryptocurrencies. They also offer a secure platform for peer-to-peer lending, enabling people to borrow money from other individuals without the need for a middleman or credit agency.

  • NFTs Marketplace

Non-Fungible Tokens (NFTs) are unique digital assets that represent ownership of a particular item. NFTs can be used in fintech apps for everything– from trading crypto-collectibles to managing online portfolios. NFT marketplaces enable users to buy and sell these tokens in a secure and transparent manner.

  • Crowdfunding Platforms

Decentralized finance (DeFi) crowdfunding platforms provide a secure way for people to invest in projects they believe in. These apps make it easy for users to participate in fundraising activities without the need for a middleman or expensive transaction fees.

  • Decentralized Crypto Exchange Platform

Decentralized crypto exchange platforms allow users to buy and sell cryptocurrencies without the need for a third-party intermediary. These platforms offer secure transaction processing, low fees, and fast settlement times, making them ideal for fintech applications.

Best Practices for Developing Blockchain-Based Fintech App

  • Choose the Type of DeFi App

Before beginning development on a fintech app using blockchain technology, it is important to identify the type and functions of the application required for your business. Conduct diligent market research to understand your competitors, and features trending among DeFi users, and identify features that align with your business. This will help you determine the most suitable blockchain technology stack for your project and minimize future technical debt.

  • Decide Tokenomics

It’s important to consider the tokenomics model of your app before you start developing, as they are an essential part of DeFi applications. Tokenomics is the design principle behind token-based economies. It includes considerations such as incentivizing early adopters of your product, maintaining liquidity in the market, and aligning user motivations with growth.

To offer features such as staking, decentralized exchanges, and liquidity pooling, you will have to introduce crypto tokens along with the mechanism to apply them through your fintech app. For creating an effective token economy, you can leverage tools like OpenZeppelin to ensure the implementation of standard tokens such as ERC721 and ERC20

  • Implement Optimized Development Processes

Developing a successful fintech app requires following a set of best practices for the development process. This includes adapting agile methodologies, test-driven development, continuous integration/delivery, and automated testing. These processes will help ensure that your app is bug-free, meets quality standards, and is ready to deploy.

  • Prioritize Security

While developing a fintech application, security must be the top priority. This means incorporating robust authentication with multi-factor authentication (MFA) and access control measures to protect user data from unauthorized access.

Additionally, developers should utilize encryption for any sensitive information and implement smart contracts for secure transactions. Your developers must be well-versed with different cyber threats such as cross-site scripting, SQL injections, etc, and implement appropriate solutions to mitigate them.

  • Focus on Enriching User Experience

When designing the UX/UI of a fintech app, it is important to keep usability principles in mind in order to create an intuitive and enjoyable experience for users. These principles include things such as simplicity, consistency, visibility, feedback, task orientation, and accessibility. Keeping these principles in mind will help ensure that your app is easy to use while also providing all the features necessary for effective financial management.

  • Develop Scalability Strategies

Building an application with scalability in mind from the outset is key to ensuring its long-term success. Utilizing the right technology stack, understanding capacity planning needs, and implementing performance optimization techniques can all help ensure your app has the capacity to grow over time with minimal downtime.

  • Follow Regulatory Compliance

The financial sector is highly regulated and fintech apps must adhere to the prevailing laws and regulations to run operations smoothly. Developers should always research legal requirements before launching an app and ensure all features comply with necessary standards. This includes considering licensing needs, consumer protection obligations, anti-money laundering and counter-terrorism financing measures, privacy policies, etc.


Developing a successful fintech application requires careful consideration of various aspects such as project scope, technology stack, user experience, scalability needs, and regulatory compliance. By following the right development processes, businesses can create an app that enables users to manage their finances in an intuitive and secure manner.

How Blockchain In Supply Chain Can Help Overcome Operational Hurdles

blockchain in supply chain
Blockchain in supply chain management

With bitcoins and cryptocurrency gaining much popularity over the last few years, its underlying technology – blockchain, seems to be the latest buzzword across industries. There seems to be a sudden urge among businesses to adopt and use the technology to significantly improve their workflow operations. The concept seems to have a promising future that would assist in solving several hold-ups of the existing technology gears. 

But first, let’s look at what blockchain technology is.

What is Blockchain?

A blockchain is a digital ledger that records all cryptocurrency transactions. It consistently keeps growing as “completed” blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the blockchain to differentiate legitimate transactions. 

Using Blockchain in Supply Chain

As per a Zion Market study, the market scope of blockchain technology in supply chain management is estimated to grow to approx. USD 3.15 billion by 2028.

The use of blockchain in the supply chain helps firms significantly in cost reduction, source tracking, and establishing trust. The immediate need to eliminate intermediaries has paved the way for the automation of supply chain operations.

Supply chain blockchains have replaced coins to tokenize different types of transaction-related data. This has thus enabled the creation of unique, transparent, and easy-to-verify detectors for purchase orders, inventory units, bills of lading, etc.

This technology governed the overall blockchain supply chain market in 2021 and is expected to continue dominating the forecast period. The reason is the growing adoption of blockchain platforms for streamlining the supply chain processes.

How Supply Chain Industry Benefits From Adopting Blockchain

Blockchain in supply chain gives increased supply chain transparency, and significantly reduces costs and risks across the supply chain. Here’s how:

  • Real-Time Sharing of Data

While blockchain records actions in a chain of “blocks” and display the most recent information, all the previous records are also saved. Blockchain ledger allows you and multiple partners to work on the same data in real-time, without losing any. However, it is to be noted that the data once recorded, cannot be altered and only be viewed.

  • Enhanced Security

As every new block created is linked to the previous blocks, it’s impossible to fabricate or modify any data. To make any changes to the ledger data, you need to make changes to hundreds of copies of that ledger at the same time. Simply put, this means it can’t be hacked. 

Additionally, blockchain data is decentralized. This implies it’s not stored in a single location like its previous supply chain tech. The data can be accessed through the cloud network from any geographic location worldwide. However, while anyone can view the records via the internet, it would need someone to verify access to any specific data.

  • Thorough Transparency 

Blockchain ensures transparency throughout the supply chain process as it’s a shared database. This transparency is vital for managing products with shorter life cycles, and also for managing the entry of additional partners in the supply chain. 

Moreover, blockchain tech enables supply chain partners to monitor transaction status in real time. They know the exact location of the product without having any doubts created by manual records. This ensures smoother processes, reduced lead times, reduced delays and redundancy, greater team relationships, and a satisfied customer.

Additionally, blockchain supply chain innovations bring about the following key benefits:

    • Improved tracking of the material supply chain to meet corporate standards
    • Reduced losses from the counterfeit or black market
    • Reduce paperwork and administrative costs
    • Improved transparency and compliance over outsourced contract manufacturing
    • Reduced probable public relations risks due to supply chain malpractices
    • Builds stakeholders’ trust and ensures their engagement and involvement

Blockchain Challenges

  • More Industries Need to Adopt

While certain industries have successfully adopted blockchain, it is yet to see increased adoption in the supply chain industry. The technology makes transactions and international payments more secure, efficient, and transparent. However, more industries are yet to implement blockchain in the future as organizations continue to experience the benefits of its implementation.

  • Need For Strong Network

The key barrier to a blockchain is the relatively small network of users. To scale up operations, all members throughout the supply chain, from the supplier to the retailer, need to use it. Since the entire blockchain ecosystem still seems new to many, more users are yet to adapt, or are still adapting to it.

  • Complexity in Handling Data

While implementing blockchain is easy, blockchain programming is something that requires users to learn complex skills. This means firms need to give comprehensive training to their workforce or outsource their programming to a third party.

  • Clustering And Anomaly Detection

Clustering and anomaly detection are unsupervised learning methods that can be used for fraud detection by identifying patterns within your data that suggest fraud may occur, such as many small withdrawals from an account or many large purchases made at one store over time.

  • Regulations

The laws and regulations seem to be another barrier to blockchain adoption. Due to the global nature of supply chains, there is an intricate range of worldwide regulations to be considered. Today’s supply chain regulators are exploring ways to integrate the old and traditional laws with the new emerging digital technologies.

However, as more users of blockchain begin to see the advantages, greater will be the number of adopters of the cloud-based database infrastructure.

Final Notes

Blockchain technology has great scope and has promising years ahead in assisting firms as well as industries. Using blockchain in supply chain can help reduce administrative costs, achieve a boost in performance by streamlining processes, and widen visibility across overall operations. New emerging technologies thus offer promising opportunities to enhance and improve the supply chain industry and the transparency within.

How Bitcoin Solves the Double-Spending Problem?

Many of us probably already have heard of Bitcoin. We know what innovation it has brought into this world – the blockchain technology. As of this writing, it has been almost a decade since its inception and it has long thrived without any central control over the network.

Bitcoin, a peer-to-peer electronic cash system, has inspired many other projects and can be seen as a pioneer of the underpinning blockchain technology. That said, it would be worth exploring how Bitcoin solves the double-spending problem. Instead of delving into theoretical exposition we will experience a transaction process in this pioneering innovation. We will be making a transaction on a real network and analyzing what a Bitcoin transaction looks like. A transaction in the Bitcoin network is a bit complex than a conventional digital transaction.


Comparison with Fiat Currency Transaction

In a transaction that involves currency notes, we can easily envisage two parties exchanging some goods or services in exchange for the money. One party receives the goods/services and the party pays in currency notes. Let us say the transaction was costing $50 and the payer has $100 currency note. The payer would pay $100 and would receive in change $50 (as shown below). Both the currency notes are legal tender that is supplied by a central bank. A Bitcoin transaction also involves paying and may too involve receiving back change and in this respect is quite similar to our day-to-day transaction.

Comparison with Conventional Digital Transaction

A conventional digital transaction, say the online transfer of money, involves two parties and a mediator (the bank). So, there is a “From address” (A/C No.), a “To address” (A/C No.) and the amount (value transfer). There is no concept of change in a conventional digital transaction. If you want to transfer $1050 then you can transfer the exact amount and this is a mere process of debiting from sender’s account and crediting to the receiver’s account with the help of the mediator who validates the transaction. However, a Bitcoin transaction may involve multiple From addresses and multiple To addresses without any mediator. We will explore how this is possible.

As it is with any traditional transaction, ours will have the following attributes: a “From entity”, a “To entity” and the value to transfer. Let us send an amount of 0.1 BTC to a Bitcoin user as follows:

From: n2FSwa6DsMsbJgNknB64ThR3pHPUQ79bxL
To: msqdPeF7KeEqcWUNAFMm8JQijVB3cnLi4N

Amount: 0.1 BTC

The transaction has been done and the transaction details can be seen here

Bitcoin Transaction

Now, what looks legitimate is the From address (left) and the one of the To addresses with 0.1 BTC sent. However, two things look contradictory. Firstly, we sent 0.1 BTC but it says 1.0 BTC being transferred. Secondly, there is one more To address to which some amount has been sent.

Is something wrong with this transaction? Not really! You can check the above transaction in block explorer and verify yourself that it is indeed the same transaction. But this is the way Bitcoin works. Let us explore.

What is a Bitcoin Transaction made up of?

A transaction in Bitcoin consists of inputs and outputs. The input is like a “From address” which is in Bitcoin terms an unspent transaction output. When you want to make a transaction you will always spend an unspent transaction output as a whole. That said, you end up paying the entire amount. However, you receive the remaining amount in a different address called change address. This change address is your own address where you collect the change, which in turn is an unspent transaction output. This is quite common in Bitcoin transactions. For instance, someone sent you 1.0 BTC. Now you want to send 0.5 BTC to your friend. You cannot break the 1.0 BTC but you will spend the entire 1.0 BTC in a transaction and get the change in your change address.

Transaction Fee

Back to our transaction. Now, let us verify that the amount in input and outputs are balanced. So, 1 BTC – (0.1 BTC + 0.89432145 BTC) should be 0. But it turns out to be 0.00567855. So, where did this amount go?

Well, this is the transaction fee that is paid to the miner who helped you in validating the transaction, adding it into a block, mining the block, and broadcasting to the network. The miner is given this amount as a mining fee for the work he has done.

The mining fee is charged in satoshi per byte. Our transaction has a size of 225 bytes and we were charged 2523.8 satoshi per byte. So, 2523.8 x 225 = 0.00567855 BTC.

The Concept of UTXO

Note that the two outputs here are mentioned as “unspent”. This is how bitcoin keeps track of balances. The sum of all unspent transaction outputs is what constitutes your balance. Bitcoin network does not have any database or global state of balance amount rather it uses the concept of UTXO.

So, how is a UTXO represented in the bitcoin protocol? Perhaps in the bitcoin protocol, there is no concept of “From address”. Yes, there is no concept of From address in Bitcoin. The Bitcoin addresses are used to receive payments. A transaction in Bitcoin never encodes a From address but only has a reference to a previous unspent transaction output. That said, the input of a Bitcoin address is actually a previous unspent output. Bitcoin refers to a previous unspent transaction output using a combination of transaction ID (or transaction hash) and an index. Once an unspent transaction is spent you cannot spend it again and thus prevent the double spending.

A Transaction with Multiple Inputs

So, how will a Bitcoin user transact an amount for which he has no unspent transaction output equal to or above that value? Say, a user wants to transfer 5 bitcoins but none of his unspent transaction output has that much amount although the user has multiple unspent transactions that add up to a value greater than 5.  Bitcoin allows you to combine unspent transaction outputs. A transaction with multiple inputs would sound new to a person doing a conventional digital transaction. This is because a conventional digital transaction always has only one sender (or From address). Let us analyze a bitcoin transaction with multiple inputs. In this case, the Bitcoin user wants to send 1.02 bitcoins but he has no unspent transaction outputs of that value. So, the user combines two inputs and then transacts (see below).

Bitcoin Transaction

The above transaction (ac194c19201a20cdd26bbb8d696588370c06261148fd20a96b3330b0bcb03207 ) has two inputs and two outputs and it is absolutely a valid transaction in Bitcoin. The total amount of BTC of these two inputs, which is 1.04997424 BTC, is sufficient to send a transaction of 1.02 BTC. And the remaining value has been collected in a change address with 0.02997013 BTC.


How are transactions validated in Bitcoin?

Let us take an example of a transaction that involves one input and one output (as below). Here,  the input is a reference to a previous unspent transaction at index 0. The previous transaction is referred by a transaction hash: f5d8ee39a430901c91a5917b9f2dc19d6d1a0e9cea205b009ca73dd04470b9a6
The output sends 50 bitcoins to a bitcoin address. When the recipient wants to spend this 50 bitcoin he will reference output 0 of this transaction as an input of his own transaction.


Previous tx: f5d8ee39a430901c91a5917b9f2dc19d6d1a0e9cea205b009ca73dd04470b9a6
Index: 0
scriptSig: 304502206e21798a42fae0e854281abd38bacd1aeed3ee3738d9e1446618c4571d10



Value: 5000000000

scriptPubKey: OP_DUP OP_HASH160 404371705fa9bd789a2fcd52d2c580b65d35549d


Bitcoin uses a scripting system to verify a transaction. There are two script components that can be seen in the above transaction: scriptPubKey and scriptSig. So, the scriptSig refers to the sender’s signature and the public key. The scriptPubKey is the script that will be evaluated using bitcoin protocol and if the execution of the script returns true then the transaction is valid.

scriptSig: <sig> <pubKey>

Let us see how this script is executed on the stack:

Step 1: Combine scriptSig and scriptPubKey in that order
Step 2: Push <sig> and <pubKey> to stack
Step 3: Execute the operation OP_DUP which will duplicate top item, which is <pubKey>
Step 4: Execute the operation OP_HASH160 which will create hash of the <pubKey> and this hash will be pushed to the stack.
Step 5: Execute the operation OP_EQUALVERIFY to ensure the hash generated matches with the <pubKeyHash>
Step 6: Execute the operation OP_CHECKSIG for the two hashes on the stack.

In summary, a Bitcoin transaction involves one or more inputs and one or more outputs, has no concept of From addresses in its protocol, uses a concept of unspent transaction output, and verifies the transaction using a scripting architecture.
