The parent blockchain may be understood as a blockchain backbone generated by an intelligent contract that includes a plurality of businesses, for example, the parent blockchain may be understood as a blockchain for storing funds flow data between enterprises a and B and contract data signed between two enterprises, wherein the funds flow data stored in the parent blockchain is data generated by the intelligent contract 1, and the contract data is data generated by the intelligent contract 2.
The business contracts are intelligent contracts, wherein the intelligent contracts are electronic agreements which can automatically execute tasks which can be completed manually, for example, contracts which can automatically calculate the payment amount of a contract principal and arrange for payment of a shielding amount.
