Blockchain Transaction Tested on GOMX-4 Constellation

March 3, 2021 by Blockchain Consultants

Blockchain Transaction Tested on GOMX-4 Constellation

According to the latest announcement, JP Morgan, an American multinational investment bank headquartered in New York City, has tested a transaction of Blockchain in space. This Blockchain transaction testing is carried out by a Danish space firm named GomSpace’s satellites.

It was reported by GomSpace that it is the world’s very first bank-led tokenized value transfer in space, executed through smart contracts on a blockchain, established between satellites orbiting the earth.

Talking about GomSpace, it is a space company that aims to be engaged for space systems and services in the global market by introducing new products depending on innovation within professional nanosatellites. 

Blockchain is a peer-to-peer, decentralized distributed ledger technology that records data in individual blocks linked to one another using cryptography. This technology is known to offer immutability, transparency, security, and privacy. 

This Discovery Opens the Opportunity to a Potential P2P Satellite Marketplace

The report announced that a Blockchain transaction was executed between two GOMX-4 satellites in the low Earth orbit (LEO), which validated the approach towards a decentralized network where communication with the earth is not required.

As private companies prepare to launch their own constellations, the report mentions that in the long term, this discovery opens the opportunity to a potential P2P satellite marketplace, allowing data transfers between satellites against payment. 

GomSpace CEO Niels Buus expressed his views regarding his team’s support for J.P. Morgan. According to Buus, he is glad to have supported them as they explored this novel use case of a space-based payment infrastructure by implementing blockchain technology.

Blockchain Era has Begun 

Gone are the days when Blockchain technology was confined to finance and cryptocurrency. Today, this technology’s potential and relevance in other areas of business are coming under the limelight. Last year in July 2020, it was announced that the first use of Blockchain in renewable energy happened in Australia.

Apart from this, recently, it was announced that Twitter has considered whether to add bitcoin to its balance sheet.

Enterprise meets DeFi: Organizations work toward adopting blockchain tech

March 2, 2021 by Blockchain Consultants

Decentralized finance is quickly maturing. While the total value locked in DeFi is over $45 billion, financial institutions and large corporations are starting to implement DeFi concepts to automate business processes. This is known as “enterprise DeFi.”

For instance, invoices and other financial products can be tokenized to ensure that transactions are valid and should be processed for payment across multiple parties. Coke One North America is one of the first large corporations to demonstrate this.

CONA is leveraging the Baseline Protocol — a project that coordinates confidential workflows between enterprises using messaging, zero-knowledge cryptography and blockchain — to tokenize invoices. CONA aims to “baseline” its entire supply chain by giving internal bottlers and external suppliers access to a private, distributed integration network.

Through use cases like CONA, such solutions are quickly gaining traction. There are also a number of vendors entering this infrastructure market including Provide, an enterprise middleware provider, and Big Four firm Ernst & Young. Most recently, ConsenSys — one of the leading blockchain software companies — announced plans to use Baseline Protocol as a solution for its enterprise clients, further demonstrating the importance of enterprise DeFi adoption.

How ConsenSys plans to drive enterprise DeFi

Specifically, ConsenSys Codefi — ConsenSys’ fintech suite that connects financial use cases to blockchain counterparts — will soon offer a baseline-compliant solution for its enterprise clients.

Didier Le Floch, institutional products and engineering lead at ConsenSys Codefi, told Cointelegraph that while the Baseline Protocol was developed by EY, ConsenSys and Microsoft, Codefi has been taking steps to ensure that its products will eventually be fully compatible with it:

“We want to enable the use of digital assets and the financing of those assets for payment use cases. These use cases will generate maximum business value, combining automation of business processes and payments using things like stablecoins, for example.”

In order to achieve this, Floch explained that the Codefi tech stack will be combined with the Baseline Protocol to deliver an effortless user experience for cases such as financing supply chains. Floch remarked that this is a first step in the right direction, as Codefi strongly believes that the enterprise sector will soon converge with the DeFi market: “There will be ebbs and flows, and it will be a journey with various steps, but we’ve already seen the promise of this convergence in the DeFi market.”

To his point, MakerDAO — the protocol behind the stablecoin Dai — announced support in June 2020 to use non-crypto-native assets, such as invoices and music streaming royalties, as collateral for its Dai stablecoin. Maker also voted to support a protocol from blockchain startup Centrifuge to bring real-world assets on its platform. Known as “Centrifuge Chain,” this is built on Parity’s blockchain development framework, Substrate.

Asset originators can use the Centrifuge Chain to mint nonfungible tokens of real-world assets, converting them to ERC-721 tokens. These assets can then be added to Tinlake, which is Centrifuge’s Ethereum-based DeFi protocol for decentralized asset financing.

A Centrifuge spokesperson told Cointelegraph that the company is currently working with MakerDAO to bring New Silver, an online real-estate lender, on to the Maker platform as an asset originator. As such, NewSilver would be the first asset originator using Tinlake to get to the MakerDAO executive vote, ultimately allowing asset originators to generate Dai as a credit facility.

DeFi protocol Aave also introduced a diversified money market to support real-world assets back in October 2020. According to the Aave blog post, this money market would make it easy for the Aave community to onboard real-world assets into the protocol, allowing investors to lend against assets, such as invoices, real estate and inventory finance. “Right now, it’s at a small scale, but there are DeFi lending protocols already taking steps to incorporate real-world assets into their protocols,” said Floch.

Breaking down barriers hampering adoption

Many enterprise DeFi concepts are still in early development, as a number of barriers exist. For instance, there are concerns regarding publicly available sources to determine the price of collateralized assets. Furthermore, many DeFi protocols venturing into the enterprise space only allow solutions for borrowing in crypto, which may be unappealing to mainstream organizations. Moreover, paying transaction fees in cryptocurrency may also be problematic for enterprises that typically deal in fiat payments.

Floch explained that Codefi’s use of Baseline Protocol is intended to address these concerns. For example, he noted that there will be an “Infura ITX” integration that will enable corporations to pay gas fees in dollars rather than Ether (ETH) when using the Baseline Protocol. Since the platform leverages the Ethereum network as its mainnet of choice, or as a common frame of reference for complex workflows, this integration will ensure a better user experience overall.

In addition, Floch mentioned that ConsenSys’ open-source zero-knowledge proof library, known as “gnark,” will be leveraged to ensure enterprise data remains private, yet verifiable.

While notable, Codefi’s implementation of the Baseline Protocol isn’t the only solution intended to solve the challenges related to enterprise DeFi adoption.

For example, EY has been heavily involved in the blockchain space, specifically in terms of enterprise DeFi development. Paul Brody, global blockchain lead at EY, told Cointelegraph that the firm has been working on DeFi enabling solutions since 2016, with the goal of making the inputs and outputs of enterprise business processes tokenized and then transactable:

“This means purchase orders, invoices, receivables, inventory — everything in traditional business-to-business processes should be ready to integrate into a DeFi ecosystem.”

Of course, Brody is aware of the challenges regarding this vision, noting that the first element to be tackled is achieving an acceptable level of privacy for enterprise users. Once this is accomplished, Brody explained that necessary standards need to be established where bodies, such as the Enterprise Ethereum Association, can be key partners in the pursuit of these goals.

Brody further mentioned that as an industry auditor, EY will not be offering financial services involving DeFi. Rather, the firm is devoted to ensuring that enterprise clients will be able to plug their business operations into existing DeFi solutions. For example, Brody explained that EY’s Network Procurement solution is designed to manage purchase orders and fulfillment, which would allow enterprises to exchange tokens for purchase orders, contracts, invoices and inventory transfers. “As soon as we see standards we can leverage, we hope that our enterprise users will be able to take advantage of these markets,” said Brody.

Institutions show interest in DeFi?

In addition to a growing number of enterprise DeFi solutions in development, there is now interest in DeFi from large organizations and financial institutions. This was recently demonstrated by the leading digital currency asset manager, Grayscale. On Feb. 26, 2021, the firm announced consideration to offer investors access to DeFi assets, including Aave, Compound’s COMP, MakerDAO’s MKR, Reserve Rights (RSR), SushiSwap’s SUSHI, Synthetix Network Token (SNX), Uniswap’s UNI and Yearn.finance’s YFI.

Although this is separate from enterprises using DeFi protocols to find real-world assets, Floch noted that this demonstrates more institutional players are ready to invest in prominent DeFi protocols:

“For institutional customers of Grayscale to start investing in those tokens is definitely a sign that they’re getting more comfortable with Defi, while understanding the value of those protocols (asset management, collateralized lending and trading automated in smart contracts).”

Prepare Yourself With These Top 30 Blockchain Interview Questions 2021

February 4, 2021 by Blockchain Consultants

Prepare Yourself With These Top 30 Blockchain Interview Questions 2021

Want to have a career in the Blockchain space? This article talks about the top 30 interview questions to get you ready for a big interview. Excited? Let’s get started.

Table of Contents 

  • Top Interview Questions You Should be Prepared for
  • Wrapping Up: How to Learn Blockchain?

Top Interview Questions You Should Know

In this section, let’s discuss the top 30 blockchain questions and answers.

1. What is the difference between Bitcoin Blockchain and Ethereum Blockchain?

Both Bitcoin and Ethereum have decentralized distributed databases of immutable records. But Bitcoin and Ethereum differ in purpose in a way that Bitcoin is considered as an alternative digital currency that offers various advantages, whereas Ethereum is regarded as the king of smart contracts that facilitates Peer-to-Peer contracts and applications via its own currency known as ETH. Ethereum was introduced with an intent to complement rather than compete with bitcoin.

2. How is Blockchain different from traditional databases?

A database is a kind of central ledger, whereas Blockchain has a distributed ledger, which means unlike the traditional databases, it is not governed by any central server. Due to this, Blockchain is a fully confidential and robust technology.

3. What is double-spending, and how can it be stopped?

It is the process of spending a balance of that cryptocurrency more than once. It is done by fooling the network to think that the original amount is never spent, thus making it available to be used for multiple transactions. 

However, this problem can be prevented in blockchain-based cryptocurrencies by utilizing a consensus mechanism known as Proof-of-Work (PoW).

Bitcoin’s solution to deal with this crucial problem is that if the majority of the nodes agree on which transaction was first to be received, later tries to double-spend are pointless.

4. Out of the three types of Blockchain, which is the best one?

Out of public, private, and consortium Blockchain, to state which one is the best would not be right because each of has its own features, usage, and requirements. If you want to design and implement your own enterprise blockchain, a private blockchain is a one-stop solution. Consortium blockchain, on the other hand, is likely to interest organizations who want to efficiently streamline communication among one another.

Features  Public  Private  Consortium 
Accessibility  Anyone  Single Person/ Central Incharge  More than one central in-charge.
Who can join? Anyone  Permissioned and known identities Permissioned and known identities
Consensus Mechanism PoS/PoW Voting or multi-party consensus algorithm Voting or multi-party consensus algorithm
Transaction Speed  Slow  Lighter & Faster  Lighter & Faster 
Decentralization Completed Decentralized  Less Decentralized  Less Decentralized 

5 How ICO differs from IPO?

ICO stands for Initial Coin Offering, whereas IPO stands for Initial Public Offering. The first difference between an ICO and an IPO is that ICO is generally for the young and risky, whereas IPO is mainly for well-settled companies. The process of issuing also differs in both. An IPO is an extensive process that requires underwriters and lengthy evaluations to determine the market price of each share. Moreover, for an IPO, you need lawyers, banks, and patience, whereas, for ICO, one needs programmers and the Internet. 

6 Name a few popular platforms for developing Blockchain-based applications?

There are multiple platforms available but before deciding on one, understand what type of Blockchain do you need, how popular is the chosen platform, what kind of scalability does your solution need, and ensure whether your preferred blockchain platform supports smart contract functionality or not. 

Blockchain platforms enable the development of blockchain-based applications that are in great demand and useful for businesses and enterprises. A few of the top platforms for developing Blockchain-based apps are Hyperledger Fabric, Ethereum, R3 Cords, Quorum, and Ripple.

7 What do you know about the lightning network?

It is an off-chain, micropayment system designed to make transaction processing faster in the Blockchain. In Lightning Network, the members can directly interact with each other without offering anything to the miners, and members can engage in numerous microtransactions with each other. And finally, when the payment channel is locked, the concluding transaction set is added to the Blockchain.

Lightning network not only helps in scalability but also makes payments instantaneous, and transactions are not dependent on miners. The network is micropayment and multi-signature friendly and, moreover, reduces the load of the main chain and decreases waiting time.

8 Distinguish between Fungible and Non-Fungible.

  • Fungible are Interchangeable: Fungible tokens are interchangeable and can be exchanged with any other token of the equivalent kind. 
  • Non-Fungible are Non-Interchangeable: Unlike Fungible tokens, such tokens are non-interchangeable as they cannot be replaced with the non-fungible token of the same type.
  • Fungible Tokens are Uniform: Each token is different from all other tokens of the same type. 
  • Non-Fungible Ones are Unique: All tokens of each type are identical in specification, and each token is identical to the other. 
  • Fungible Tokens are Divisible: These tokens can be divisible into smaller units, and one can get any number of units, and it does not matter to holders as long as the value remains the same.
  • Non-Fungible Tokens are Non-Divisible: These tokens cannot be divided in any sense.  

9 What is Blockchain Wallet?

A blockchain wallet can be defined as a digital wallet or E-wallet that allows individuals to store, manage, and transfer their cryptocurrencies such as Bitcoin(BTC), Ethereum(ETH), and many more. With such wallets, users can manage their balances of these two cryptocurrencies by paying transaction fees that depend on various factors such as transaction size. Since digital assets or cryptocurrencies are just a number, that is why the wallet keeps the private key of any particular individual, and the private key fetches the balance of that individual from the Blockchain.

10 Explain the features of DeFi.

  • Autonomy — DeFi platforms ensure that your assets are all yours, and no one has control over them.
  • Enables affordable and faster cross border payments
  • Tradability — You can trade more efficiently as they aren’t prone to an entire high-value investment at once.
  • Accessibility: DeFi has a financial system that is accessible to everyone regardless of their location.
  • Interoperability: DeFi apps and protocols are built to integrate and complement one another.
  • Transparency — In the DeFi environment, data is available publicly, which helps keep service providers impartial.
  1. Question: What are the requirements for implementing Blockchain technology for enterprise usage?

Answer: Here are the most basic ones:

  • Is the network peer-to-peer? 
  • Does the system offer smart contract functionality for the execution of decentralized applications or not? 
  • Can data be stored permanently without compromising the security measures?
  • Does it offer decentralized data storage?
  • What are its data privacy aspects? 
  • Is the immutability ensured?

12 Question: What is blockchain mining? 

Answer: Blockchain mining is a process by which transactions of a blockchain are verified without involving any third-party. Every time a transaction is sent from a Bitcoin wallet, it is sent to the transaction pool. Miners then pick hundreds of transactions and combine them to form a block with other overheads like Merkel Root, SHA-256 Hash, Nonce, etc. 

13 List some of the top blockchain development tools. 

  • Solidity
  • Remix
  • Geth 
  • Meta Mask
  • Truffle Framework

14 What, according to you, are the key Challenges for Blockchain Adoption

  • Scalability 
  • Interoperability 
  • Energy Consumption 
  • Lack of Talent 
  • Lack of standardization 

15 What are the drawbacks of Blockchain?

It is a complex technology that is hard to understand and implement. Scalability is another issue related to Blockchain. Moreover, network speed and transaction costs vary, and human errors still persist. 

16  Is it possible in Blockchain to remove one or more blocks from the networks?

No, it is not possible to manually remove a block. However, blocks can be removed with the help of default options and filters. Deleted blocks can be re-downloaded again whenever needed.

17 Enlist key features of Blockchain technology.

Transparency– Transparency is one of the significant issues in the current industry. Although to improve it, organizations have attempted to implement more rules and regulations, but there is one thing that doesn’t make any system completely transparent,i.e., centralization. But with the help of Blockchain, organizations can go for a complete decentralized network where there is no need for a centralized authority, improving the transparency of the system.

Immutability– Blockchain is immutable, meaning nobody can modify the data over a blockchain. This feature enables companies to ensure that there is no hamper of data, making their system more functional in a highly competitive market. 

High Availability– As we already defined Blockchain as a decentralized system of peer to peer network, thus it is highly available due to the concept of decentralization. It offers decentralized services that provide unique access to the options that are otherwise unavailable.

Security– Unlike traditional databases, Blockchain provides a high level of security to its users. High security is due to the cryptographic algorithms which are being run behind the Blockchain. Rather than trusting any individual or third party, in the Blockchain, one needs to trust only cryptographic algorithms.

Fast Dealing- Traditional banking organization takes a lot of time in initiating and processing the transactions and is prone to human error and often requires a third-party intermediary. Blockchain can streamline and automate the entire process without any human intervention and with complete accuracy.

Reduced Transaction Fees- As Blockchain removes the involvement of the third party, it eliminates the overhead cost of exchanging the assets; thus, it leads to reduced transaction fees. 

18 Mention types of Consensus Algorithms?

  • Proof-of-Work (PoW)
  • Proof-of-Stake (PoS)
  • Delegated Proof-of-Stake (DPoS)
  • Proof-of-Authority (PoA)
  • Proof-of-Elapsed Time (PoET)
  • Byzantine Fault Tolerance

19 Explain how PoW consensus works.

The central principle behind PoW consensus is to solve complex mathematical problems and make the largest number of guesses as quickly as possible. Such requires a lot of computational power, and by using a more efficient mining machine to run calculations, a miner can maximize profitability in terms of crypto rewards. 

In this type of consensus mechanism, miners compete to be the first one to find a hash regarding a particular block, which can only be solved using sheer computing power to make the largest number of guesses. When a miner finds the right solution, they advertise it to the whole network, receiving a reward in cryptocurrency provided by the protocol. 

20 Explain the Concept of PoS

Proof-of-Stake is a consensus algorithm that deals with the main drawbacks of PoW. In this mechanism, every block gets validated before the network adds another block to the blockchain ledger. Unlike PoW, where miners have to solve complex puzzles, in PoS, miners can join the mining process using their coins to stake. It allows users to mine for rewards using very minimal hardware and software resources. Here, the mining capacity of a particular miner depends on how many coins they already have; thus, the more coins one has, the better chances are, which indicates only the richest can have control of the consensus. 

21 Define the term CBDC

CBDC stands for Central Bank Digital Currency, which is controlled directly by the country’s central bank and is backed by national credit and government power. 

In other words, CBDC is an electronic form of central bank money that can be used to store value and make digital payments seamlessly.

22 What is DeFi technology? Explain the term, DeFi Pulse 

Decentralized Finance can be defined as financial services using smart contracts that don’t need any central authority and uses decentralized, distributed ledger technology, Blockchain. Most of the DeFi protocols are based on the Ethereum Blockchain network. 

DeFi Pulse is a data site that lets individuals find the latest analytics and rankings of all DeFi protocols. Pulse rankings track the total value that is locked into the smart contracts of DeFi protocols so that individuals can stay up to date on the latest trends.

23 What is Hyperledger Fabric? 

Hyperledger Fabric is a distributed ledger platform that comes with versatility, modularity, and performance specially crafted to provide enterprise-grade solutions. It is an open-source enterprise-grade permissioned DLT platform known to provide modularity and versatility for a broad set of industry use cases, including banking, insurance, healthcare, supply chain, human resources, etc.

24 What are Smart Contracts? What are its benefits?

A smart contract is used to describe computer code that can facilitate the exchange of money, content, shares, or anything of value. When running on the Blockchain, smart contracts becomes like a self-operating computer program that executes automatically when desired conditions are met. Since such contracts run on the Blockchain, they run exactly as programmed, without any possibility of censorship, downtime, fraud, or any third-party interference. 

  • No intermediaries ensure a quick transaction process
  • Secure and Efficient
  • No Middleman, more savings 
  • Works with accuracy and precision 
  • Establish confidence
  • Automation saves time and effort. 

25 What are dApps? Mention some of the popular dApps.

Decentralized applications (dApps) are digital applications that exist and run on a peer to peer network of computers instead of a single computer. 

Some of the dApps that are popular, innovative, and feature-rich are:

  • Cipher
  • Chainlink 
  • EOS Dynasty
  • TraceDonate 
  • Brave  

26 Explain the role of Blockchain in Governance

Due to increased decentralization, data integrity, and transparency, along with better efficiency and reduced operational costs, blockchains are becoming popular in governance. From improving transparency to streamlining the tax collection mechanism, Blockchain distributed networks can help governments to operate more efficiently and build higher levels of trust among their citizens. 

27 Mention some of the myths related to Blockchain. 

  • Blockchain and Cryptocurrencies are the same. 
  • All blockchains are public blockchains.
  • Technology only targets the finance domain. 
  • Blockchain is just a database.
  • Blockchain is free and highly accessible. 

28 Are there any restrictions for putting records in Blockchain?

No, there is no such restriction. One can store any kind of record, depending upon their requirements. The most common type of records that are recorded in Blockchain are records of transaction processing, identity management, business transactions, health management data, and all other crucial documentation.

29 Is Blockchain a trusted approach?

Blockchain is undoubtedly a trustable technology that helps participating parties to share their valuable data in a secure and tamper-proof manner. It makes use of cryptography for securing crucial information, thus making it extremely hard for attackers to play with stored data. Due to its high potential to provide security, it is widely adopted and implemented by various organizations and businesses for their operations.

30 What do you know about the future of Blockchain?

Blockchain is likely to discover a whole new way of economic transactions and contribute to global economic development immensely. Although its mainstream adoption is yet to be achieved, once it is done, it will change the way businesses operate and transform the landscape of the technology sector forever.

How Blockchain technology offers improvements to payments security

Blockchain is disrupting industries like Fintech, Agriculture, Supply Chain Management, Pharmaceuticals, and Real Estate Registry. It has found unique solutions to some of the most pressing concerns of modern time. With the advent of big data and analytics, blockchain also provides pioneering solutions in data management.

The first and foremost application was found in the payments industry, with the introduction of cryptocurrencies, making them faster and more secure. In this article, we will look at how blockchain structure and Blockchain Payment Gateways can help make our payments secure.

Blockchain can be described as a living ledger with a network of peers who participate and monitor the assets and their transfers. They individually hold all the data of the blockchain but are collectively responsible for approving transactions. Data once approved is immutable and disincentives are present for shady or unscrupulous practices. This decentralized system has improved the efficiency, reliability, and security of countless industries.

Cryptocurrencies were the first application of blockchain technology, bitcoin, being the first of its kind. Any transaction or modification is accessible by all the users on the public ledger, adding a level of security. Just like fiat currencies issued by Central Banks, cryptocurrencies have all the properties: scarcity, fungibility, and non-repudiation but are not issued by a central authority. Instead, bitcoins are mined by solving complex mathematical puzzles related to the stamping of a transaction. Moreover, as this solution is impossible to falsify, it makes the complete architecture secure and very easy to verify.

The PCI (Payment Card Industry) Security Standards Council, a global forum created by leading payment networks such as American Express, Visa, and the likes believe that the payment industry is seldom prepared for changes. It works reactively to new threats and all-new payment method implementations are vulnerable to more modern attacks. For example, all critical payments information including credit card numbers, currently pass through the merchant’s payment systems and become the potential place for security breaches. A Blockchain Payment Gateway Development has the potential to eliminate this shortcoming.

Cryptocurrency is already accepted by a plethora of merchants and its usage is witnessing an upward trend. Consultants at PCI state that cryptocurrencies challenge these traditional approaches to privacy, trust, and security by its decentralized structure.

So far, centralized systems have controlled how payments are executed and users upheld their trust in the central institutions responsible for privacy and security. On the other hand, a cryptocurrency functions not on trust but on the integrity of the underlying algorithms governing the structure.

Every node holds a copy of the ledger and the protocol is governed by an MIT license open-source software. It uses a number of public security primitives and data structures that are well established. These include but are not limited to SHA256 hashes, Merkle trees, and Elliptic Curve Asymmetric Cryptography.

A group of transactions are used to form a block and this block is assigned a unique SHA256 hash. The subsequent block holds this hash key from the previous block and the cycle continues. This exercise links all the blocks to each other and forms a chain, which is known as a blockchain. Hence, it becomes impossible to modify a transaction once it has entered a block.

Firstly, cryptocurrencies provide an alternative to the current payment systems and highlight the flaws in the latter. Secondly, it provides a strong underlying architecture which can be used by Blockchain Development Companies to prepare future payment gateways and enhance security.

Cryptocurrencies are legal in most countries and with better regulations, its mainstream application can be witnessed pretty soon. The costs associated with cryptocurrencies to send and receive money are negligible compared to the current charges levied by card issuers, banks, and other intermediaries. Removal of intermediaries would also lead to shorter execution time and reduced risk of security breaches. A Blockchain Payment App Development would leverage all these benefits and provide a fool-proof, secure, inexpensive, and fast way to make payments.

Blockchain has the potential to acquire a huge market in the micropayments industry. Payment networks levy heavy charges in the form of a fixed + variable fee which goes exorbitantly high while handling very small payments.

The payments industry has seen major overhauls but struggled to keep pace with the growing internet and payment demands. Payment security is a big concern, especially when money is sent across borders and involves an exchange. In such a scenario, information passes through multiple processors and increases the likelihood of a data breach. A Blockchain Technology Payment Security offers the perfect solution through its decentralized system, thereby reducing intermediaries, costs, and risks in executing payments.
