Optimistic execution is a method used to enhance transaction processing efficiency on blockchain networks. It assumes that most transactions are valid and processes them without immediate verification.In this approach, when a user submits a transaction, it gets executed and added to the blockchain right away. The system operates on the assumption that the majority of users act honestly. This speeds up the transaction finalization process.However, there’s a safety net. If someone believes a transaction was executed incorrectly, they can challenge it within a certain timeframe. During this dispute period, the system will verify the transaction’s validity, potentially rolling back any incorrect executions.This method contrasts with more cautious approaches that verify every transaction before adding it to the blockchain. By balancing speed and security, optimistic execution aims to improve scalability while maintaining the integrity of the network.
