The Coprocessor created by Lagrange is not just for saving gas; it fundamentally reshapes the logic of whether "off-chain data can be reliably brought on-chain".
Imagine a complex AI reasoning task, cross-chain verification, or large-scale simulation results that could not be directly used on the blockchain before, because the chain could not bear the computational load and could not guarantee the correctness of the results. Lagrange uses STARK proofs to allow the results generated from these off-chain tasks to be lightly verified by on-chain contracts, truly achieving reliable input.
LA plays four roles in this:
1. Payment: Task submitters must pay rewards using LA.
2. Staking: Execution nodes must stake LA to ensure integrity.
3. Penalty: Errors or fraud will destroy the staked assets.
4. Governance: Token holders can participate in system parameter adjustments and upgrade proposals.
This design makes LA not just a "token", but a trust unit responsible for order, risk, and incentives.
