This is another approach proposed for speeding up the transaction on a blockchain network.
The basic idea is to use side channels for state updating and processing transactions off the main chain; once the state is finalized, it is written back to the main chain, thus offloading the time-consuming operations from the main blockchain.
Off-Chain Transactions That Keep Blockchains Fast and Cheap
State channels work by performing the following three steps: 1.
First, a part of the blockchain state is locked under a smart contract, ensuring the agreement and business logic between participants.
Now off-chain transaction processing and interaction is started between the participants that update the state only between themselves for now.
In this step, almost any number of transactions can be performed without requiring the blockchain and this is what makes the process fast and a best candidate for solving blockchain scalability issues.
However, it could be argued that this is not a real on-blockchain solution such as, for example, sharding, but the end result is a faster, lighter, and robust network which can prove very useful in micropayment networks, IoT networks, and many other applications.
Once the final state is achieved, the state channel is closed and the final state is written back to the main blockchain.
Why This Matters for Blockchain Technology
At this stage, the locked part of the blockchain is also unlocked.
This process is

Conclusion
State channels represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.
Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
