# FOGR blockchain implementation

FOGR network is a distributed ledger, which aims to provide a cost-effective way to run the application logic core to run the FOGR computing platform, store device data information and provide the trading system. It uses FHPoS consensus protocol to reach consensus.

Both internal and external users of the FOGR computing platform can access the blockchain, which is a new protocol specially built from scratch for the FOGR computing platform.
