📌 Proof of Stake (PoS) Summary
Proof of Stake (PoS) is a method used by some blockchains to confirm transactions and add new blocks. Instead of relying on powerful computers to solve complex problems, PoS selects validators based on how many coins they own and are willing to lock up as a guarantee. This system is designed to use less energy and resources compared to older methods like Proof of Work. Validators are rewarded for helping to secure the network, but they can lose their staked coins if they act dishonestly.
🙋🏻♂️ Explain Proof of Stake (PoS) Simply
Imagine a school election where the more tokens a student is willing to put aside, the more likely they are to be chosen to count votes. This means students who care about the results are trusted more. In PoS, those with more coins at stake have a bigger chance to validate transactions, but they risk losing their coins if they cheat.
📅 How Can it be used?
A project can use Proof of Stake to secure its blockchain network while reducing energy consumption.
🗺️ Real World Examples
Ethereum switched from Proof of Work to Proof of Stake in 2022. Now, people who want to help validate transactions must lock up a minimum amount of Ether as a stake. If they work honestly, they earn rewards. If they try to cheat, they can lose their staked Ether.
The Cardano blockchain uses Proof of Stake, allowing users to delegate their coins to staking pools. These pools validate transactions and add new blocks, distributing rewards to participants based on their contributions.
✅ FAQ
How does Proof of Stake work in simple terms?
Proof of Stake lets people who own a cryptocurrency help run the network by locking up some of their coins as a promise to play fair. The more coins you lock up, the more likely you are to be chosen to check transactions and add new blocks. This approach uses much less energy than older systems that rely on lots of computing power.
Why do some blockchains use Proof of Stake instead of Proof of Work?
Many blockchains use Proof of Stake because it is much more energy-efficient and environmentally friendly than Proof of Work, which needs powerful computers running all the time. With Proof of Stake, the network is secured by people putting their coins at risk, so it saves electricity and makes it easier for more people to take part.
Can you lose your coins with Proof of Stake?
Yes, if someone tries to cheat or break the rules while acting as a validator in a Proof of Stake system, they can lose some or all of the coins they have locked up. This rule helps keep everyone honest and protects the network from attacks.

Application Security Testing
Application security testing is the process of checking software to find and fix security problems before they can be exploited. This involves scanning code, running tests, and reviewing how the application handles data to prevent attacks such as hacking or data theft. The goal is to make applications safer for users and organisations by identifying and fixing weaknesses early.
Customer Loyalty Program
A customer loyalty programme is a marketing strategy that rewards customers for repeatedly choosing a companynulls products or services. The aim is to encourage repeat business by offering incentives like points, discounts or exclusive offers. These programmes help businesses build long-term relationships with their customers and increase customer retention.
Event Stream Processing
Event stream processing is a way of handling data as it arrives, rather than waiting for all the data to be collected first. It allows systems to react to events, such as user actions or sensor readings, in real time. This approach helps organisations quickly analyse, filter, and respond to information as it is generated.
Feature Selection Strategy
Feature selection strategy is the process of choosing which variables or inputs to use in a machine learning model. The goal is to keep only the most important features that help the model make accurate predictions. This helps reduce noise, improve performance, and make the model easier to understand.
Graph Feature Modeling
Graph feature modelling is the process of identifying and using important characteristics or patterns from data that are represented as graphs. In graphs, data points are shown as nodes, and the connections between them are called edges. By extracting features from these nodes and edges, such as how many connections a node has or how close it is to other nodes, we can understand the structure and relationships within the data. These features are then used in machine learning models to make predictions or find insights.
