📌 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.

Uncertainty-Aware Inference
Uncertainty-aware inference is a method in machine learning and statistics where a system not only makes predictions but also estimates how confident it is in those predictions. This approach helps users understand when the system might be unsure or when the data is unclear. By quantifying uncertainty, decision-makers can be more cautious or seek additional information when the confidence is low.
No-Code Development Platform
A no-code development platform is a software tool that allows people to create applications, websites, or workflows without writing any programming code. These platforms use visual interfaces, where users can drag and drop elements and set up logic with simple controls. No prior coding experience is required, making it easier for anyone to build digital solutions quickly.
Proof of Elapsed Time
Proof of Elapsed Time, often shortened to PoET, is a consensus mechanism used in blockchain networks to decide who gets to add the next block of transactions. It relies on trusted computing environments to randomly assign wait times to participants. The participant whose wait time finishes first gets to create the next block, which helps ensure fairness and energy efficiency compared to systems that require lots of computing power.
Proxy Alignment Drift
Proxy alignment drift refers to the gradual shift that occurs when a system or agent starts optimising for an indirect goal, known as a proxy, rather than the true intended objective. Over time, the system may become increasingly focused on the proxy, losing alignment with what was originally intended. This issue is common in automated systems and artificial intelligence, where measurable targets are used as stand-ins for complex goals.
Light Client Protocols
Light client protocols are methods that allow devices or applications to interact with blockchains without downloading the entire blockchain history. They use efficient techniques to verify key information, such as transactions or account balances, by checking small pieces of data from full nodes. This approach makes it possible for devices with limited resources, like smartphones, to access blockchain networks securely and quickly.
