What does "Off-chain computation" really mean? Why are more and more blockchain projects starting to emphasize this term?
In simple terms, Off-chain computation is a practice that allows you not to have to process everything on the blockchain. Because on-chain computation is expensive, inefficient, and has poor scalability, off-chain computation can be performed first, and then the results can be submitted for on-chain verification.
This is precisely where the Lagrange Coprocessor comes into play.
You can think of it as a co-processor that helps the blockchain "extend its capabilities." The main chain does not need to handle complex computations directly; it just waits for the Coprocessor to submit the answers and proofs, which can then be quickly verified.
This design brings several key benefits:
1. Significant efficiency improvement: There is no need to execute every step on-chain, reducing gas costs.
2. Increased application flexibility: It can handle more complex logic, such as data aggregation, leaderboards, and cross-chain computation.
3. The proof is verifiable: There is no need to trust a particular node, only to trust cryptographic proofs.
We are no longer in an era where "if it can't be done on-chain, don't do it at all"; rather, we have entered a new era of "if it can't be done on-chain, hand it over to the Coprocessor."
Lagrange stands at the forefront of this transformation, creating a blockchain world where data is combinable and logic is verifiable.
