Flash Accounting

Definition

Flash accounting refers to the instantaneous recording and settlement of financial transactions on a blockchain. This method leverages the atomic nature of blockchain transactions, where all steps within a complex operation either succeed entirely or fail completely, ensuring immediate and verifiable finality. It allows for the simultaneous execution of multiple interdependent financial actions, such as borrowing, trading, and repaying, all within a single block transaction. This capability significantly reduces settlement risk and enables highly capital-efficient operations in decentralized finance (DeFi).
