Ethereum sign transaction

An Ethereum transaction needs to be included in a block and mined before it is processed and saved on the blockchain. As a result, on-chain transactions takes time and costs gas to compensate miners for their work. In contrast, off-chain computation lets you perform actions instantly without waiting for transactions to be mined and does not cost any gas. In this article, let's look at how you can perform off-chain computation using Ethereum signatures. Cryptographic signatures.
