The Lagrange Coprocessor handles not just computations, but also "trusted inputs." The limitation of on-chain contracts is that they can only accept results processed on-chain. However, the Coprocessor utilizes STARK technology to enable external computation results to be verified on-chain, ensuring that the sources are trustworthy and the logic is correct.
The economic guarantee behind this is LA. Each Prover must stake LA before taking on a task; if the proof submitted is incorrect or delayed, they will lose the staked tokens. Additionally, the submitter uses LA as part of the task fee, with rewards automatically distributed by the system, and a portion being burned, creating a long-term deflationary model.
This structure makes LA not just a token, but an indispensable trust bridge in the entire trustworthy off-chain computation system.
