Smart contract implementation mechanisms

A method for completing multiple smart contracts, comprising:

• generating, by a smart contract application installed on a first user device, a first proposal for a first smart contract;
• creating a first set of parameter options for completing the first smart contract, and displaying the first set of parameter options via the first user device;
• transmitting, by the first user device, the first proposal for the first smart contract to a set of second user devices specified by the first set of parameter options;
• only when required parameters in the first set of parameter options are met, completing the first smart contract by the smart contract application installed on the first user device, and notifying each of the second user devices
• generating, by a smart contract application installed on a third user device, a second proposal for a second smart contract;
• creating a second set of parameter options for completing the second smart contract, and displaying the second set of parameter options via the third user device;
• transmitting, by the third user device, the second proposal for the second smart contract to a set of fourth user devices specified by the second set of parameter options;
• only when required parameters in the second set of parameter options are met, completing the second smart contract by the smart contract application installed on the third user device, and notifying each of the fourth user devices.
