Off-chain

Off-chain refers to any transaction or interaction that occurs outside of the primary blockchain network. This can include sidechains, payment channels, or other methods of conducting transactions that don't rely solely on the main blockchain. Off-chain solutions are often used to improve speed and scalability, as they allow for faster and more efficient processing of transactions without burdening the main network. Additionally, off-chain solutions can help reduce transaction fees and improve privacy for users. Ultimately, off-chain solutions are designed to help improve the overall performance and functionality of blockchain technology.
