All About UPI

UPI stands for Unified Payments Interface. It is a payment mode developed by the National Payments Corporation of India. UPI is a payment system that allows you to transfer money between any two parties. As compared to NEFT, RTGS, and IMPS, UPI is far more well-defined and standardized across banks. This means that you can use UPI to initiate a bank transfer from anywhere in just a few clicks! The benefit of using UPI is that it allows you to pay directly from your bank account. The hassle or need to type in the card or bank details goes away with UPI. You can use UPI to transfer money to your family, friends, or even between your own bank accounts. The much wider use of UPI comes when you have to pay different merchants. mPIN in UPI Another benefit of using UPI is that you can do away with the need to wait for an OTP and enter it to complete the money transfer. The mPIN is a 6-digit passcode that you must enter every time you need to make a transaction. The mPIN is highly val

What Is the Smart Contract?

What is the Smart Contract?



Now you can listen to this article via Spotify click on the player below:


Smart contracts defined

Smart contracts are simply programs stored on a blockchain that run when predetermined conditions are met. They typically are used to automate the execution of an agreement so that all participants can be immediately certain of the outcome, without an intermediary’s involvement or time loss. They can also automate a workflow, triggering the next action when conditions are met.

How smart contracts work:

Smart contracts work by following simple “if/when…then…” statements that are written into code on a blockchain. A network of computers executes the actions when predetermined conditions have been met and verified. These actions could include releasing funds to the appropriate parties, registering a vehicle, sending notifications, or issuing a ticket. The blockchain is then updated when the transaction is completed. That means the transaction cannot be changed, and only parties who have been granted permission can see the results.

Within a smart contract, there can be as many stipulations as needed to satisfy the participants that the task will be completed satisfactorily. To establish the terms, participants must determine how transactions and their data are represented on the blockchain, agree on the “if/when...then…” rules that govern those transactions, explore all possible exceptions, and define a framework for resolving disputes.

Then the smart contract can be programmed by a developer – although increasingly, organizations that use blockchain for business provide templates, web interfaces, and other online tools to simplify structuring smart contracts.


Benefits of smart contracts:

Speed, efficiency, and accuracy

Once a condition is met, the contract is executed immediately. Because smart contracts are digital and automated, there’s no paperwork to process and no time spent reconciling errors that often result from manually filling in documents.

Trust and transparency

Because there’s no third party involved, and because encrypted records of transactions are shared across participants, there’s no need to question whether information has been altered for personal benefit.

Security

Blockchain transaction records are encrypted, which makes them very hard to hack. Moreover, because each record is connected to the previous and subsequent records on a distributed ledger, hackers would have to alter the entire chain to change a single record.

Savings

Smart contracts remove the need for intermediaries to handle transactions and, by extension, their associated time delays and fees.

All About Web 3.0

Article Duration: 15 min Now you can listen to this article via Spotify click on the player below: Imagine a new type of internet that not only accurately interprets what you input, but actually understands everything you convey, whether through text, voice, or other media, one where all content you consume is more tailored to you than ever before. We are at the tipping point of a new phase in the web’s evolution. Some early pioneers call it Web 3.0. Arguably, there are a few early-stage Web 3.0 applications that already exist today, but until the new internet becomes fully embedded in the web infrastructure, their true potential cannot be observed. Definition: What Is Web 3.0? Web 3.0 is the upcoming third generation of the internet where websites and apps will be able to process information in a smart human-like way through technologies like machine learning (ML), Big Data, decentralized ledger technology (DLT), etc. Web 3.0 was originally called the Semantic Web by World Wide Web in

Zero-day vulnerability: What it is, and how it works

A zero-day exploit is when hackers take advantage of a software security flaw to perform a cyberattack. And that security flaw is only known to hackers, meaning. Software developers have no clue about its existence and have no patch to fix it. This is why, when a zero-day attack is detected, it needs to be mitigated immediately. In other words, there are “zero days” to fix vulnerability because it’s already been exploited. Here, we’re zeroing in on the zero-day concept, including just what is a zero-day exploit, and how to avoid them. 1. Zero-day definitions: What is zero-day? The term “zero-day” refers to a newly discovered software vulnerability and the fact that developers have zero days to fix the problem because it has been — and has the potential to be — exploited by hackers. Sometimes written as 0-day, zero-day definitions run the gamut: A zero-day vulnerability , also known as a zero-day threat, is a flaw in security software that’s unknown to someone interested in mitig
