An off-chain transaction refers to a transaction that occurs outside of the main blockchain network. In a blockchain system, transactions are typically recorded on the distributed ledger, which is the main chain. However, off-chain transactions are processed and recorded separately from the main blockchain, often to improve scalability and reduce transaction fees.[1][2]
The key characteristics of off-chain transactions are:
They are executed and recorded outside of the main blockchain, typically on a separate layer or network.
They can be used to perform high-volume, low-value transactions without burdening the main blockchain.
