# Calculation contract

FOGR supports large-scale complex computing contracting. FOGR uses smart contract to make computing have corresponding legal and economic attributes, so that computing can be implemented and encouraged in a self-organizing way. Smart contracts can "release the power of data" and highly protect data privacy while encouraging full data sharing.
