Lagrange is not about making blockchain capable of doing everything, but about enabling it to 'trust' things that were previously impossible. AI reasoning, cross-chain messaging, game calculations, IoT data analysis... these tasks are too heavy to be handled directly on-chain. But you also can't trust the off-chain results without any basis, which is where the Coprocessor comes into play.
After the Coprocessor completes the calculations off-chain, it generates a STARK proof, allowing the on-chain to verify once at a low cost to confirm whether the entire logic is correct, without needing to redo it.
And LA is the economic support for all of this:
• Users pay task fees with LA
• Nodes stake LA to take on tasks, ensuring integrity
• Errors or fraud will trigger a destruction mechanism
• Successful tasks will distribute rewards and trigger token deflation
This is the infrastructure for trusted off-chain computation, and LA is the trust core of this system.
