Smart contracts in blockchain environments
Digital or “smart” contracts execute in a blockchain environment. Any entity (whether public or private) may specify a digital contract via a blockchain. Because there may be many digital contracts offered as virtual services, the contract identifier uniquely identifies a particular decision table and/or the digital contract offered by a virtual machine, vendor or supplier. The blockchain is thus not burdened with the programming code that is required to execute the decision table and/or the digital contract. The blockchain need only include or specify the contract identifier (and perhaps one or more contractual parameters), thus greatly simplifying the blockchain and reducing its size (in bytes) and processing requirements.
1. A method performed by a server that identifies a network resource executing a digital contract, the method comprising:
identifying, by the server, a contract identifier specified by a blockchain, the contract identifier associated with the digital contract;
identifying, by the server, a network address associated with the network resource by querying an electronic database that associates the contract identifier to the network resource;
sending, by the server, a service request to the network address requesting an execution of the digital contract; and
receiving a service result of the execution of the digital contract.
2. The method of claim 1 , further comprising generating a data record in a blockchain data layer that describes the service request sent to the network address requesting the execution of the digital contract.
3. The method of claim 2 , further comprising transacting a cryptocoinage in response to the generating of the data record in the blockchain data layer.
4. The method of claim 1 , further comprising transacting a cryptocoinage in response to the sending of the service request.
5. The method of claim 1 , further comprising generating a data record in a blockchain data layer that describes the service result.
6. The method of claim 1 , further comprising transacting a cryptocoinage in response to the receiving of the service result.
7. A system that identifies a network resource executing a digital contract, comprising:
a hardware processor; and
a memory device storing instructions that when executed by the hardware processor perform operations, the operations comprising:
identifying a contract identifier specified by a blockchain, the contract identifier associated with the digital contract;
identifying a network address associated with the network resource by querying an electronic database having entries associating network addresses to contract identifiers including an entry of the entries that associates the contract identifier to the network address;
sending a service request to the network address requesting an execution of the digital contract; and
receiving a service result of the execution of the digital contract.
8. The system of claim 7 , wherein the operations further comprise generating a data record in a blockchain data layer that describes the service request sent to the network address requesting the execution of the digital contract.
9. The system of claim 8 , wherein the operations further comprise transacting a cryptocoinage in response to the generating of the data record in the blockchain data layer.
10. The system of claim 7 , wherein the operations further comprise transacting a cryptocoinage in response to the sending of the service request.
11. The system of claim 7 , wherein the operations further comprise generating a data record in a blockchain data layer that describes the service result.
12. The system of claim 7 , wherein the operations further comprise transacting a cryptocoinage in response to the receiving of the service result.
13. A memory device storing instructions that when executed by a hardware processor perform operations, the operations comprising:
identifying a contract identifier specified by a blockchain, the contract identifier associated with a digital contract;
identifying a network address associated with a network resource by querying an electronic database for the contract identifier, the electronic database electronically associating network addresses to contract identifiers including the network address associated with the contract identifier;
sending a service request to the network address that is electronically associated with the contract identifier that uniquely identifies the digital contract, the service request requesting an execution of the digital contract; and
receiving a service result of the execution of the digital contract.
14. The memory device of claim 13 , wherein the operations further comprise generating a data record in a blockchain data layer that describes the service request sent to the network address requesting the execution of the digital contract.
15. The memory device of claim 14 , wherein the operations further comprise transacting a cryptocoinage in response to the generating of the data record in the blockchain data layer.
16. The memory device of claim 13 , wherein the operations further comprise transacting a cryptocoinage in response to the sending of the service request.
17. The memory device of claim 13 , wherein the operations further comprise generating a data record in a blockchain data layer that describes the service result.
