📌 State Channels Summary
State channels are a technique used in blockchain systems to allow two or more parties to carry out multiple transactions without needing to record each one on the blockchain. Instead, the parties communicate directly and only add the final result to the blockchain. This reduces costs and avoids delays caused by waiting for blockchain confirmations. State channels help improve scalability by taking frequent or repetitive transactions off the main blockchain, making them faster and cheaper for users.
🙋🏻♂️ Explain State Channels Simply
Imagine two friends playing several rounds of a game and keeping score on a piece of paper instead of telling the referee after every round. They only report the final score when they finish. In the same way, state channels let people transact privately and quickly, and only update the main blockchain when they are done.
📅 How Can it be used?
A payment app could use state channels to let users send money back and forth instantly and only settle the total on the blockchain.
🗺️ Real World Examples
In a gaming platform, players can use state channels to bet and settle winnings across multiple rounds. Instead of recording each bet and payout on the blockchain, which would be slow and expensive, the platform records only the final balances after all rounds are complete, saving time and transaction fees.
A group of businesses that regularly trade with each other can open a state channel to handle their ongoing payments. They can exchange funds repeatedly off-chain and only close the channel and settle the final net amounts on the blockchain, reducing both transaction costs and network congestion.
✅ FAQ
What are state channels and why are they useful?
State channels let people make lots of transactions with each other without putting every single one on the blockchain. Instead, they only record the final outcome, which saves money and time. This is especially useful for things like games or frequent payments, where speed and low fees matter.
How do state channels make blockchain transactions faster and cheaper?
By allowing people to interact directly and only saving the end result on the blockchain, state channels avoid the usual wait for confirmations and high transaction fees. This makes it possible to complete many transactions quickly and at a much lower cost.
Can anyone use state channels or are they only for experts?
State channels are designed so that anyone can use them, not just experts. Many apps and platforms are working to make the process simple, so regular users can enjoy quicker and cheaper transactions without needing to understand all the technical details.

Payment Channels
Payment channels are a technology that allows two parties to conduct multiple transactions between each other without recording every transaction on a public blockchain. Instead, only the opening and closing balances are recorded, which helps reduce fees and increase transaction speed. This method is commonly used to make frequent or small payments more efficient.
Centralised Exchange (CEX)
A Centralised Exchange (CEX) is an online platform where people can buy, sell, or trade cryptocurrencies using a central authority or company to manage transactions. These exchanges handle all user funds and transactions, providing an easy way to access digital assets. Users typically create an account, deposit funds, and trade through the exchange's website or mobile app.
Data Validation Framework
A data validation framework is a set of tools, rules, or processes that checks data for accuracy, completeness, and format before it is used or stored. It helps make sure that the data being entered or moved between systems meets specific requirements set by the organisation or application. By catching errors early, a data validation framework helps prevent problems caused by incorrect or inconsistent data.
Data Exfiltration
Data exfiltration is the unauthorised transfer of data from a computer or network. It often happens when someone gains access to sensitive information and moves it outside the organisation without permission. This can be done through various means, such as email, cloud storage, or portable devices, and is a major concern for businesses and individuals alike.
Query Generalisation
Query generalisation is the process of making a search or database query broader so that it matches a wider range of results. This is done by removing specific details, using more general terms, or relaxing conditions in the query. The goal is to retrieve more relevant data, especially when the original query returns too few results.
